Back Clinic Power & Strength Training. These types of conditioning programs are for both athletes and the general population. They can reach higher levels of personal power and strength, making them capable of achieving their personal fitness goals. Power is defined as the ability to generate as much force as fast as possible. It’s needed for athletic movements such as workouts (clean & jerk), swinging a bat, golf club, tennis racket, and running through a tackle.
Power requires strength and speed to develop force. Strength is the amount of force muscle/s can exert against an external load. One rep maximum test is performed where individuals assess the greatest weight they can lift while maintaining proper form. The movement’s speed is not important in a strength test. Dr. Alex Jimenez offers insight into various stretches and exercises and explains the possible risks of injury on strength training through his numerous article archives.
Can weight and strength training increase speed and power in athletes that participate in throwing sports?
Throwing Sports
Top-throwing athletes have amazing arm speed. To succeed in throwing sports athletes need to be able to generate quick explosive power. This means the ability to propel the arm forward with substantial velocity for maximum object delivery like a baseball, javelin, hammer throw, shot put, discus, etc. Combined with sports technique training, throwing strength and power can be increased by training with weights. Here is a three-phase training plan to improve throwing performance.
Full Body
The arm provides only one part of the delivery process.
The legs, core, shoulders, and general flexibility need to work cooperatively to exert maximum thrust and achieve maximum object speed.
The natural ability to throw fast with power is largely determined by an individual’s muscle type, joint structure, and biomechanics. (Alexander E Weber, et al., 2014)
Preparation
Preparation should provide all-around muscle and strength conditioning for early pre-season conditioning.
Athletes will be doing throwing training as well, so fieldwork will need to be able to fit in.
It is recommended not to do weight training prior to throwing practice.
This leads to the start of competition and tournament play.
Frequency
2 to 3 sessions per week
Type
Strength and power – 60% to 70% for one-rep max/1RM
The one-repetition maximum test, known as a one-rep max or 1RM, is used to find out the heaviest weight you can lift once.
When designing a resistance training program, individuals use different percentages of their 1RM, depending on whether they’re lifting to improve muscular strength, endurance, hypertrophy, or power. (Dong-Il Seo, et al., 2012)
Throwing practice and competition are the priorities.
Before competition begins, take a 7- to 10-day break from heavyweight sessions while maintaining throwing workouts.
Weight training during competition should provide maintenance.
Frequency
1 to 2 sessions per week
Type
Power – lighter loads and faster execution than in the preparation stage.
Exercises
3 sets of 10
Rapid movement, 40% to 60% of 1RM.
Squats
Power hang clean and press
Romanian deadlift
Lat pulldown
Incline bench press
Crunches
Rest
Between sets 1 to 2 minutes.
Training Tips
Athletes have individual needs, so a general program like this needs modification based on age, sex, goals, skills, competitions, etc.
A certified strength and conditioning coach or trainer could help develop a fitness plan that can be adjusted as the athlete progresses.
Be sure to warm up prior to weight training and cool down afterward.
Don’t try to train through injuries or try to progress too fast – it is recommended not to throw or do weights when treating or recovering from an injury. (Terrance A Sgroi, John M Zajac. 2018)
Focus on the fundamentals and practice proper form.
Take a few weeks off at the end of the season to recover after hard training and competition.

For athletes, the vertical jump is a skill that can be increased and improved with proper training. To improve jumping abilities for sports like basketball, tennis, volleyball, or track and field events such as the high jump it is necessary to do both strength and power training. Research has found certain key components can help athletes become better at jumping. There are different ways to improve an individual’s vertical jump. Here we go over some of the most effective exercises including plyometrics, and exercises that build strength and power.
Vertical Jump Increase and Improvement
Jumping is an explosive movement.
To jump well, an individual needs a consistent powerful spring.
This is achieved by training the explosive/fast-twitch muscle fibers with the ability to shorten and stretch dynamically.
Upper body strength is important for creating upward momentum.
Strength exercises involve slow, controlled movements like squats, lunges, and step-ups with weights.
Power exercises involve explosive, quick movements.
Plyometrics involve explosive hopping, bounding, and jumping drills that combine strength and speed.
Exercises
Plyometrics
Common plyometric exercises include hops, jumps, and bounding movements.
A popular exercise is jumping off a box and rebounding off the floor then jumping onto another, higher box.
Box jumps provide practice for jumping.
Single-Leg Squats
Single-leg squats can be done almost anywhere, without equipment.
They work the hips, hamstrings, quadriceps, gluteus maximus, and calves.
They strengthen the core and increase flexibility.
Full Squats
This is a barbell exercise to build strength and power.
It is considered one of the best total body exercises.
Weighted Step-Ups
The step-up is a recommended all-around exercise that can be done almost anywhere.
Not only will it build strength in your quadriceps, but you can also use it as part of a cardio workout.
It has a low risk of injury.
Overhead Walking Lunges
All that is needed is a weight and room to walk.
This exercise builds power, strength, and speed in the legs.
Improves core strength.
Stair Running
This is a high-intensity workout that builds speed, power, and cardiovascular fitness.
It targets the glutes, quads, and calves.
Agility Drills
Agility drills can include jumping to improve coordination, speed, power, and specific skills.
Sprints
Sprints are quick intense exercises to build muscle and increase performance.
Sprints use more muscle groups.
Practice
Build strength by performing basic weight training exercises using slow, controlled movements.
Build power with faster dynamic movements.
Improve movement speed to create power with explosive, quick exercises.
Work on form, by incorporating the lead-up to the jump, arm motion, and safe landing technique.
Include time to practice maximum jumping and bring it all together.
Always warm up before jumping or performing drills to keep the joints and body safe.
Athletes jump rope to get the blood circulating and warm up their muscles.
Do several slow, controlled toe raises to prepare the feet and ankles for jumping and landing.
Gradually work up to a full vertical jump, by doing box and squat jumps.
Jumping
When finally working on the vertical jump, start with the feet hips-distance apart.
If measuring jump height, stand about a foot away from the measuring tape or measuring bar on the side.
Start with arms overhead.
As you drop into a squat position swing the arms behind the hips.
Swing back up to the starting position before going for the full jump.
The pre-swing helps build momentum.
Land with the knees bent to minimize the impact.
Jumping is a high-impact activity that can take a toll on the knees, hips, ankles, and feet. Be sure to rest the body between hard workouts so the muscles have time to recover, repair, and build up.

Fitness, exercising, weight, and strength training programs use terms like sets, reps, and rest intervals. Knowing what they mean and how to use them for optimal results is important to achieve health goals. An individual’s training program will differ in the weights, reps, sets, rest intervals, and execution speed depending on whether the training is for fitness, muscle growth, strength, power, or endurance. Here we offer a strength training guide on understanding these terms and how they apply to a workout program.
Strength Training Guide
Reps
Rep means repetition.
A rep is one completion of an exercise, such as one bench press, or one bicep curl.
So, one bicep curl equals one rep, and 10 bicep curls equals 10 reps.
Reps make up a set, which is typically the total number of reps done before taking a break.
A repetition maximum – 1RM is an individual’s personal best or the most they can lift once in a single repetition.
A 10RM would be the most an individual could lift and successfully perform 10 reps with proper form.
Sets
A set is a series of repetitions performed sequentially.
For example, one set of bench presses could be eight reps
Sets are designed according to the individual’s workout program.
Rest
The rest interval is the time of resting between sets that allow the muscles to recover.
The rest period between sets can range from 30 seconds to two minutes.
Exercises can have short or long rests between reps.
The ideal rest period depends on the objective of the workout and health goals.
Not resting long enough and starting with another set too soon can fatigue the muscles too soon, increasing the risk of injury.
Resting too long between reps can cool the muscles down and release tension before starting again.
Execution Speed
The speed at which one rep of an exercise is performed is contraction velocity.
Concentric – shortening of the muscle is often the lifting part of a rep.
Eccentric – lengthening of the muscle, often the lowering part of a rep helps to build muscle mass.
Strength: 1 to 2 seconds concentric and eccentric
Hypertrophy: 2 to 5 seconds concentric and eccentric
Endurance: 1 to 2 seconds concentric and eccentric
Power: Less than 1 second concentric and 1 to 2 seconds eccentric
Choosing Weights
The distribution of repetitions against a percentage of 1RM maximum lift is as follows. This example uses a bench press where 1RM is 160 pounds.
100% of 1RM: 160 pounds, 1 repetition
60% of 1RM: 96 pounds, warm-up reps
85% of 1RM: 136 pounds, 6 repetitions
67% of 1RM: 107 pounds, 12 repetitions
65% of 1RM: 104 pounds, 15 repetitions
An individual should be able to do one lift at 1RM, six reps at 85%, 15 reps at 65%, and so on.
Goals to Build a Program
A training program is a schedule of exercise types, frequency, intensity, and volume, for weight training or any other type of fitness training. Individuals can devise various combinations of sets, reps, rest, and exercise types to find what works best for them. A qualified strength and conditioning trainer can help develop a program. The variables can be adjusted and include:
Exercise selection
Weights or resistance used
Number of reps
Number of sets
Execution speed
Rest time between sets
Rest time between training sessions and days of the week
General Fitness
A basic strength training fitness program targets strength and muscle-building.
Between eight and 15 repetitions for two to four sets will help achieve both.
Choose eight to 12 exercises, making sure to hit the lower and upper body and core.
Strength
Building strength uses the most weight, the least number of reps, and the longest rest periods.
The neuromuscular system responds to heavy weights by increasing the body’s ability to lift heavy loads.
For example, individuals with a strength goal could use a 5×5 system.
This means five sets of five repetitions.
Muscle Growth
Muscle growth and bodybuilding training use lighter weights, more reps, and less rest periods.
Muscle requires metabolic stress to increase in size.
This means working the muscles to the point where lactate builds and the muscle suffers internal damage, sometimes called “training to failure.”
Then resting and proper nutrition help muscle repair and the muscle grows larger in the process.
A program could be three sets of 8 to 12 reps, with loads that reach or near the failure point on the last few reps.
Power
Power training uses slightly lighter weights, takes longer rest periods, and focuses on execution speed.
Power is the ability to move an object at high speed.
Each push, pull, squat, or lunge is done at a quick tempo.
This type of training requires practicing the acceleration of a lift, resting properly, and repeating.
Muscular Endurance
Endurance weight training requires more reps in each set, up to 20 or 30, with lighter weights.
Individuals should ask themselves what is the day-to-day physical activity that requires the most muscular endurance?
For example, runners will want to concentrate on increasing endurance in their legs.
Swimmers may shift and focus on their arms one day then legs another.

Individuals can become overly passionate about exercising. However, constantly training the body without taking enough time to rest and recover can impact athletes and fitness enthusiasts physically and mentally and lead to overtraining syndrome. Excessive training can cause decreases in athletic physical performance that can be long-lasting, sometimes taking several weeks or months to recover. Individuals who don’t learn to manage overtraining can have injuries and more frequent illnesses and infections. And the psychological effects can also lead to negative mood changes. Learn the signs and how to cut back to prevent injury and/or burnout.
Overtraining Syndrome
Athletes and fitness lovers often exercise longer and harder than average to reach peak performance. Even individuals just getting started with exercise can push their limits as they try to figure out what works for them. This means taking into consideration the following:
The mental side of training.
How to get and stay motivated.
How to set up a safe and effective program with balanced cardio and strength training.
How to avoid skipping workouts when things get in the way.
Exercising too much is a mistake many beginners make, putting themselves at risk for injury.
Overtraining syndrome is when the body goes through and feels:
Extreme fatigue.
Physical performance problems.
Mood changes.
Sleep disturbances.
Other issues due to working out or training too much and/or too hard without giving the body enough time to rest.
Overtraining is common among athletes who train beyond their body’s ability to recover, usually when preparing for a competition or event. Conditioning for athletes and enthusiasts requires a balance between work and recovery.
Signs and Symptoms
There are several signs to look for, with the more common symptoms being:
Mild muscle or joint soreness, general aches, and pains.
Decreased training capacity, intensity, or performance.
Lack of energy, constantly tired, and/or drained.
Brain fog.
Insomnia.
Decreased appetite or weight loss.
Loss of enthusiasm for the sport or exercise.
Irregular heart rate or heart rhythm.
Increased injuries.
Increased headaches.
Feeling depressed, anxious, or irritable.
Sexual dysfunction or decreased sex drive.
Lower immunity with an increase in colds and sore throats.
Prevent Overtraining
Predicting whether there is a risk of overtraining can be tricky because every person responds differently to various training routines.
Individuals have to vary their training throughout and schedule adequate time for rest.
Individuals who believe they may be training too hard should try the following strategies to prevent overtraining syndrome.
Take Note of Mental and Mood Changes
Methods exist to test for overtraining objectively.
One is taking note of psychological signs and symptoms associated with changes in an individual’s mental state can be an indicator.
Decreased positive feelings for exercise, physical activities, and sports.
Increased negative emotions, like depression, anger, fatigue, and irritability, can appear after a few days of intense training.
If these feelings and emotions begin to present, it is time to rest or dial the intensity down.
Training Log
A training log that notes how the body feels daily.
It can help individuals notice downward trends and decreased enthusiasm.
This can help individuals learn to listen to their body’s signals and rest when necessary.
Monitor Heart Rate
Another option is to track changes in heart rate over time.
Monitor heart rate at rest and specific exercise intensities while training, and record it.
If the heart rate increases at rest or a given intensity, this could be a risk indicator, especially if symptoms develop.
Track resting heart rate each morning.
Individuals can manually take a pulse for 60 seconds immediately after waking up.
Individuals can also use a heart rate monitor or fitness band.
Any marked increase from the norm may indicate that the body has not fully recovered.
Treatment
Rest and Recovery
Reduce or stop the exercise and allow the mind and body a few rest days.
Research on overtraining shows that complete rest is the primary treatment.
Take Extra Rest Days
Starting anything new will usually make the body sore.
Be prepared for the aches and take extra rest days when needed.
The body won’t have the same energy levels from day to day or even from week to week.
Consult A Trainer
Not sure where to start or how to approach working out safely.
This is the time to meet with a professional who can look at physical and medical history, fitness level, and goals.
They can develop a customized program to meet specific needs.
Nutrition and Hydration
Maintain optimal body hydration with plenty of H2O/water and rehydrating drinks, vegetables, and fruits.
Staying properly hydrated is key to both recovery and prevention.
Getting enough protein and carbohydrates supports muscle recovery.
Carbs are important for endurance, and protein is important for muscular strength and power.
Sports Chiropractic Massage
Research shows that sports massage benefits muscle recovery and can improve delayed onset muscle soreness/DOMS.
Massage keeps muscles loose and flexible and increases blood circulation for expedited recovery.
Relaxation Techniques
Stress-reduction techniques such as deep breathing and progressive muscle relaxation exercises can improve rest and recovery.
Total recovery from overtraining syndrome can take a few weeks or longer, depending on the individual’s health status and how long the excessive training has gone on. A physician can refer individuals to a physical therapist or sports chiropractor, who can develop a personalized recovery plan to get the body back to top form.

Power is the combination of strength and speed over time. Strength is how much force an individual can exert. Powerishow fast an individual can exert force. Strength training for power, aka power training, is being able to exert a certain amount of force in a given time. Power can be built with weight training. However, power strength training is not just for weightlifters. Many athletes like football, basketball, and volleyball players, sprinters, dancers, and wrestlers build strength to increase power, improve explosiveness, increase their vertical leap/jump, and give their bodies a break from heavy weight training.
Power Strength Training
Building strength is one factor, but becoming powerful requires another element in training. Biologically, individuals train the muscles to elongate and contract fast so the body can perform a certain set of movements.
Benefits
The benefits of power strength training.
Promotes Active Body Rest
Power training gives the mind and body a break from heavy training.
Provides the tendons, joints, and central nervous system a rest.
Offers a fun and healthy change with jumping, throwing, swinging, etc.
A study found individuals with knee osteoarthritis that participated in high-intensity strength training, compared with low-intensity, had a reduction in knee pain symptoms.
Improves Vertical Jump
Vertical jump or leap is how high an individual can jump and is a common parameter for assessing athletic ability.
It is an integral part of movement training programs to improve sports performance.
Research has shown that power strength and jump training can improve jump height.
Training Program
Before starting any exercise program, it is recommended to talk with a doctor. Key components to focus on when training for power.
Going above this frequency can be intense on the body and central nervous system.
Limiting sessions to a few times a week gives the body time to recover.
Equipment
Because power training involves a combination of increasing force and speed, using the right equipment that allows both is important. However, there are ways to improve without equipment.
For practicing jumps, increase the force by increasing the distance using a taller box.
For practicing push-ups on the floor, increase the force by pushing with more power so the hands come off the ground.
To improve power by increasing speed, exercises can be performed faster or with decreased rest between sets.
Weight
The weight depends on an individual’s one-rep max or the heaviest weight that can be lifted in a single repetition.
This is essentially an individual’s record for whatever type of weightlifting is being done.
Power training movement options: Plyometrics, Ballistic, or Dynamic.
Plyometrics includes activities like squats or jump lunges, common with football and basketball players.
Ballistic training includes activities like a back squat for football or soccer players.
Dynamic training works for sports-specific training motions like golf swinging or tennis serving.
Nutrition
Whether cardio or strength training, adequate caloric intake is important regardless of workout type, this means having a healthy balance of the three macronutrients: carbohydrates, fat, and protein.
Carbohydrates could be the most important, as research has shown that high-intensity exercise like power training improves when eating carbohydrates before, during, and after the workout.
Fat is necessary, and a daily intake below 20% of calorie intake can decrease the absorption of various essential nutrients.
It is recommended to consume 1.2-1.7 grams of protein per kilogram of individual body weight.
As with any exercise, training takes time, and it’s important to gradually progress only when the body is prepared. Incorporating the elements of a healthy lifestyle includes a balanced, nutrient-rich diet and proper sleep and rest days. This will help get the most benefits and prevent injuries.

The biceps curl is an exercise to build strength in the upper arm. Curls are a common exercise used in upper-body strength training. Specifically, the curl works the muscles in the front of the upper arm. It’s recommended for achieving strength and definition and provides core and stability challenges. Injury Medical Chiropractic and Functional Medicine Clinic can educate individuals on fitness, strength training, nutrition, and injury prevention.
Bicep Curls
Located at the upper arm, the biceps comprise a short and long head that operates as a single muscle.
The bicep heads begin at different places around the shoulder/scapula region,
They have a common insertion point on the elbow tendon.
Together allow the bending of the arm at the elbow joint to curl and pull weight.
Curls work the muscles at the front of the upper arm and the lower arm. The brachialis and brachioradialis.
Dumbbells
Different equipment and grips can be used, including dumbbell weights, kettlebells, barbells, resistance bands, or cable machines. Select equipment with enough weight that can be lifted ten times using proper form, ensuring the last three repetitions are challenging to the point of being unable to raise another. From there, use this same weight to perform eight repetitions or slightly lower the weight and perform ten repetitions.
Begin by standing with the feet about hip-width apart.
Keep the abdominal/core muscles engaged.
Hold one dumbbell in each hand.
Relax the arms down at the sides with palms facing forward.
Keep the upper arms stable and shoulders relaxed.
Bend at the elbow and lift the weights so the dumbbells approach the shoulders.
Raise the dumbbells to eye or forehead level for a full range of motion.
Tension will be felt in the muscles in the front of the upper arm.
Keep movements smooth and controlled.
The elbows should stay tucked in close to the body.
Be careful to keep the wrist straight and rigid.
Flexing the wrist while bending the elbow won’t target the biceps effectively and can result in a wrist or elbow injury.
Exhale while lifting.
Lower the weights to the starting position.
For most, one set of 12 to 15 repetitions is adequate.
Train to failure performing the desired reps, staying within 3 to 5 repetitions of total failure.
When able, slightly increase weight and/or reps over time to increase muscle and strength.
Both biceps can be worked out by alternating arms.
Get the most out of the workout by avoiding these errors.
Rushing Through
Focus on proper form and avoid rushing through the workout.
Lift the weights with a smooth motion.
Take as much time to lower the weight as when lifting it.
Lowering the weight slowly can help build more muscle, making the most of the workout.
Improper Elbow Position
The position of the elbows should remain close to the side of the body.
Only the lower arm should move until the end of the movement when the elbows rise. This is a complete range of motion.
If the elbows move away from the torso or swing behind the body, there is probably too much weight.
Avoid Swinging the Weights
Focus on maintaining a tall, upright spine and a tight core.
The shoulders or torso should not swing the weights up when doing the curl.
It can feel like swinging, twisting, or heaving movements.
Don’t let the hips hinge, or the lower body assist the movement.
Keep the elbows at the sides until they naturally rise at the end of the motion.
Keep the shoulders relaxed
Make sure the shoulders don’t move forward to initiate the movement.
Use lighter weights or reduce the number of repetitions if this happens.
Safety
This exercise is generally recommended for most individuals. However, getting clearance from a primary caregiver before beginning any exercise routine is recommended.
Individuals with an arm injury or who experience pain during the motion should not perform the exercise without a doctor’s approval.
Don’t try to lift weights that are too heavy.
After a few lifts, expect to feel fatigued and a burning sensation in the biceps and forearm muscles.
This is the desired effect to get the muscles strong and growing.
Do not force extra repetitions once proper form cannot be achieved.
These muscles are in constant use when picking things up.
Consistently performing the biceps curl will help build strength in the upper arm.
Individuals learn to use their arm muscles correctly and with the core muscles.

Mountain and trail biking is a fun way to exercise. Mountain biking requires total body/core strength, explosive power, balance, endurance, and agility to maneuver the bike, build speed, and absorb the rough bumps and terrain. But it also means that certain muscles get overused, causing overcompensation in the body that can lead to musculoskeletal problems and conditions. Strength, cardiovascular, and cross-fit can benefit mountain biking training for improved performance, safer and more confident riding, and injury prevention.
Mountain Biking Training
A few of the benefits of training are:
Increasing bone density.
Improving joint health.
Correcting imbalances and unhealthy posture.
Weight loss.
Aging muscle loss prevention.
Maintaining body posture centered on the bike requires core strength to perform the movements when moving the body backward and forwards, side to side, and pushing up and down when different obstacles pop up. The exercises’ objective is to work various body parts simultaneously and diagonally, like the movements used on the bike.
General Overview of Mountain Biking Training
Build strength – Target the quads, hamstrings, and abdominal muscles to power pedaling strokes.
Increase endurance – Avoid getting fatigued early because of weakened legs and aerobic performance.
Improve mountain bike skills – Ride faster and more efficiently by improving bike handling and technical skills.
Example Training Week
The terrain determines the intensity, but the same basic principles apply to mountain biking training as other endurance sports. Here’s a training example for a beginner that can be adjusted to the rider’s needs:
Monday
Stretching and training the muscles to relax prevent becoming stiff or cramping up during rides.
Cornering is a critical skill that should never stop being practiced and improved.
Cornering Drills
Pick a corner on a local trail and ride through it until mastered.
Focus on riding smoothly through the corner, and speed will generate.
As confidence builds in the corners, do the same on the opposite side.
Straighten Out
Ride to the furthest outside edge when approaching the turn.
Initiate the turn just before the sharpest point of the corner.
Stick to the furthest outside point of the corner when riding out of the corner.
Brake Before The Corner
Braking in the corner can cause the tires to slide out of control, causing a slip-and-fall accident.
Look through the turn as the bike follows where the eyes look.
Don’t stare at the front wheel, which could lead to a falling or flipping accident.
Eventually, riders can handle this technique, but it’s too advanced for beginners.
Smooth Ride
Beginners can be amazed at how much terrain bikes can ride over and through. Modern mountain bike suspension and tire systems can handle it. However, using the correct technique is essential to get through or around the obstacles and avoid crashes.
Stay aware of the surroundings.
Keep the body loose when approaching obstacles.
Decide how to overcome the obstacle – ride over, pop/raise the wheels, jump, or ride around.
Maintain confidence.
When riding over the obstacle, maintain an even balance on the pedals and keep the buttocks slightly off the saddle.
Keep arms and legs loose and let the body absorb the shock of the obstacle.
Trust the suspension and tires.
Ensure enough speed is generated to go over it and that it won’t stop the bike and cause a fall.
Some rough trail areas can require added strength to hold the bike steady.
Braking
There is no need to squeeze the brake handles with extreme force.
Extreme braking, especially the front, will likely lead to a flip or crash.
The brakes are made to stop with minimal force.
Beginners are recommended to learn to use a light touch when braking.
Improvement will follow with each riding session.
