Back and Spinal Fitness at PUSH as Rx leads the field with a laser focus on supporting our youth sports programs. The PUSH-as-Rx System is a sport-specific athletic program designed by a strength-agility coach and physiology doctor with a combined 40 years of experience working with extreme athletes.
The program is the multidisciplinary study of reactive agility, body mechanics, and extreme motion dynamics at its core. A clear quantitative picture of body dynamics emerges through continuous and detailed assessments of the athletes in motion and under directly supervised stress loads.
Exposure to the biomechanical vulnerabilities is presented to our team. Immediately, we adjust our methods for our athletes to optimize performance. This highly adaptive system with continual dynamic adjustments has helped many of our athletes return faster, stronger, and ready post injury while safely minimizing recovery times.
Results demonstrate clear improved agility, speed, decreased reaction time with greatly improved postural-torque mechanics. PUSH-as-Rx offers specialized extreme performance enhancements to our athletes no matter the age.
For individuals looking to improve their fitness health, can a fitness assessment test identify potential areas and help evaluate overall health and physical status?
Fitness Assessment
A fitness test, also known as a fitness assessment, helps evaluate an individual’s overall and physical health. It comprises a series of exercises to design an appropriate exercise program for general health and fitness. (National Strength and Conditioning Association. 2017) Fitness assessment testing benefits include:
Identifying areas that need improvement.
Assisting professionals in understanding what types of exercise are safest and most effective.
Helping measure fitness progress over time.
Allowing for an individualized plan that can help prevent injuries and maintain the body’s overall health.
An assessment can comprise a wide range of tests, including:
Body composition tests.
Cardiovascular stress tests.
Endurance tests.
Range of motion tests.
They are meant to ensure the individual won’t be at risk of injury and provide the trainer with the insights needed to establish clear and effective fitness goals. Individuals who wonder whether fitness testing would benefit them should consult their healthcare provider.
General Health
Before starting a fitness program, it is important to inform the trainer of individual medical history and get the necessary approval from a primary healthcare provider. (Harvard Health Publishing. Harvard Medical School. 2012) Fitness specialists usually use one or more screening tools to help determine individual baseline health.
This may include obtaining vital sign measurements like height and weight, resting heart rate/RHR, and resting blood pressure/RBP. Many trainers will also use a physical activity readiness questionnaire/PAR-Q comprising questions about general health. (National Academy of Sports Medicine. 2020) Among the questions, individuals may be asked about the medications being taken, any problems with dizziness or pain, or medical conditions that may impair their ability to exercise.
Body Composition
Body composition describes total body weight components, including muscles, bones, and fat. The most common methods for estimating body composition include:
Bioelectrical Impedance Analysis – BIA
During BIA, electrical signals are sent from electrodes through the soles of the feet to the abdomen to estimate body composition. (Doylestown Health. 2024)
These measurements use calipers to estimate the amount of body fat in a fold of skin.
Cardiovascular Endurance
Cardiovascular endurance testing, also known as stress testing, measures how efficiently the heart and lungs work to supply oxygen and energy to the body during physical activity. (UC Davis Health, 2024) The three most common tests used include:
12-minute Run Tests
Twelve-minute run tests are performed on a treadmill, and an individual’s pre-exercise heart and respiration rates are compared with post-exercise heart and respiration rates.
Exercise Stress
Exercise stress testing is performed on a treadmill or stationary bike.
It involves using a heart monitor and blood pressure cuff to measure vital signs during exercise.
VO2 Max Testing
Performed on a treadmill or stationary bike.
V02 max testing uses a breathing device to measure the maximum rate of oxygen consumption during physical activity (UC Davis Health, 2024)
Some trainers will incorporate exercises like sit-ups or push-ups to measure response to specific exercises.
These baseline results can be used later to see if health and fitness levels have improved.
Strength and Endurance
Muscle endurance testing measures the length of time a muscle group can contract and release before it fatigues. Strength testing measures the maximal amount of force a muscle group can exert. (American Council on Exercise, Jiminez C., 2018) The exercises used include:
The push-up test.
Core strength and stability test.
Sometimes, a trainer will use a metronome to measure how long the individual can keep up with the rhythm. The results are then compared to individuals of the same age group and sex to establish a baseline level. Strength and endurance tests are valuable as they help the trainer spot which muscle groups are stronger, vulnerable, and need focused attention. (Heyward, V. H., Gibson, A. L. 2014).
Flexibility
Measuring the flexibility of joints is vital in determining whether individuals have postural imbalances, foot instability, or limitations in range of motion. (Pate R, Oria M, Pillsbury L, 2012)
Shoulder Flexibility
Shoulder flexibility testing evaluates the flexibility and mobility of the shoulder joint.
It is performed by using one hand to reach behind the neck, between the shoulders, and the other hand to reach behind the back, toward the shoulders, to measure how far apart the hands are. (Baumgartner TA, PhD, Jackson AS, PhD et al., 2015)
Fitness assessment testing has various benefits. It can help trainers design a personalized workout program, help individuals identify fitness areas that need improvement, measure progress, and add intensity and endurance to their routine, which can help prevent injuries and help maintain overall health. We focus on what works for you and strive to better the body through researched methods and total wellness programs. These natural programs use the body’s ability to achieve improvement goals. Ask a healthcare professional or fitness professional for guidance if you need advice.

For individuals wanting to improve core stability, can using the right size exercise or stability ball help improve workouts and achieve goals?
Exercise Stability Ball
An exercise ball, stability ball, or Swiss ball is a piece of fitness equipment used in gyms, Pilates and yoga studios, and HIIT classes. (American Council on Exercise. 2014) It is inflated with air to supplement bodyweight workouts or improve posture and balance. It can also be used as a chair. They add a core stability challenge to almost any exercise (American Council on Exercise, N.D.) Getting the appropriate exercise ball size and firmness for your body and purpose will ensure an optimal workout.
Size
The exercise ball size should be proportional to individual height.
Individuals should be able to sit on the ball with their legs at a 90-degree angle or slightly more, but not less.
The thighs should be parallel to the ground or angled slightly down.
With the feet flat on the floor and the spine straight, not leaning forward, backward, or sideways, the knees should be even with or slightly lower than the hips.
Getting the right exercise ball for weight is also important. Individuals who are heavy for their height may need a larger ball to keep the knees and legs at the correct angle. It is recommended to check the weight rating of the ball, its durability, and its high burst resistance before buying.
Inflation
Individuals want a little give on the ball’s surface for exercise. When sitting on the exercise stability ball, body weight should create a little seat and provide more stability. More importantly, it allows sitting evenly on the ball, which is essential for exercising with proper spinal alignment. (Rafael F. Escamilla et al., 2016) Inflation is a matter of preference, but the more inflated the ball is, the more difficult it will be to balance the body, whether sitting or in other positions. It is recommended not to over-inflate the ball at the risk of bursting. The ball may require reinflation occasionally, so many are sold with a small pump for this purpose.
Exercises and Stretches
Exercise balls are highly versatile, inexpensive, and easy-to-use workout tools. They are beneficial for improving core strength and stability. Ways to be used include:
Target exercises for core activation and strengthening.
At Injury Medical Chiropractic and Functional Medicine Clinic, we focus on what works for you and strive to create fitness and better the body through research methods and total wellness programs. These natural programs use the body’s ability to achieve improvement goals and athletes can condition themselves to excel in their sport through proper fitness and nutrition. Our providers use an integrated approach to create personalized programs, often including Functional Medicine, Acupuncture, Electro-Acupuncture, and Sports Medicine principles.

Can improving breathing patterns help further fitness and optimize overall health for individuals who walk for exercise?
Improve Breathing and Walking
Exercising is a moment in which breathing can quicken and become labored if not done correctly. There is a proper way to breathe when exercising, especially when walking or speed walking. Breathing incorrectly causes rapid fatigue and exhaustion. Controlling the flow of one’s breath improves endurance and cardiovascular health, and it can also amplify metabolism, mood, and energy levels. (Hsiu-Chin Teng et al., 2018) Known as diaphragmatic breathing, it is used for those with reduced lung capacity, like individuals with chronic obstructive pulmonary disease/COPD. The practice improves lung capacity and is a recommended way to help relieve stress.
Physiology
During exercise, the oxygen inhaled converts the calories consumed into energy that fuels the body. This process is referred to as metabolism.
When the oxygen supply exceeds the body’s oxygen needs, the body is in an aerobic state. This means there is plenty of oxygen to fuel physical activity/exercise as there are calories to burn.
If the oxygen supply falls short of the body’s oxygen needs, the body falls into an anaerobic state.
Deprived of oxygen, the body turns to stored fuel in the muscles, known as glycogen.
This delivers a powerful burst of energy, but the fuel is quickly spent and fatigue and exhaustion soon follow.
Increasing airflow in and out of the lungs can prevent early exhaustion and help the body burn calories more effectively. (Your lungs and exercise. Breathe 2016)
Improved Breathing Benefits
Optimal breathing starts in infancy. When a baby breathes, their belly rises and falls. This facilitates respiration by pushing and pulling the diaphragm – the muscle that separates the lungs and abdominal cavity. When the baby inhales, the belly extends, pulling the diaphragm downward and allowing the lungs to fill with air. When the baby exhales, the belly draws in, pressing the diaphragm upward and forcing air out. As the body ages and the capacity of the lungs increases, individuals shift from belly-breathing to chest-breathing. Chest breathing involves the chest wall muscles with little use of the diaphragm. Chest breathing usually provides enough air for everyday activity but does not fill the lungs.
This is why individuals resort to mouth-breathing or gasping when the oxygen supply is limited. Even those in decent physical shape may be inadvertently undermining efforts by sucking in their stomach to look thinner, depriving themselves of complete inhalations and exhalations. To overcome this, individuals need to re-train their bodies to activate the abdominal muscles when walking. Belly or diaphragmatic breathing can extend the duration of exercise while strengthening the core muscles. (Nelson, Nicole 2012) By increasing core stability, individuals can better support the spine and maintain a healthy posture when walking. This stabilizes the hips, knees, upper back, and shoulders, making the body less prone to strain, instability, and fatigue from unhealthy posture. (Tomas K. Tong et al., 2014)
Breathing Correctly
The inhalation draws the belly out, pulls the diaphragm down, and inflates the lungs. Simultaneously, it extends the ribcage and lengthens the lower spine. This forces the shoulders and collarbone backward, further opening the chest. Exhaling does the reverse.
Walking
Start by inhaling and exhaling through the nose, ensuring that the inhalation duration matches the exhalation duration. When picking up the pace, individuals can resort to mouth-breathing, maintaining the same inhalation/exhalation rhythm. At no time should breathing be held in. Learning diaphragmatic breathing takes time, but the following steps can be a starting point:
Inhale by inflating the belly fully on a count of five.
Allow the lungs to fill, drawing the shoulders back as this happens.
Exhale by pulling the belly button toward the spine on a count of five.
Use the diaphragm to press the air out of the lungs, keeping the spine erect.
Repeat.
If unable to maintain a count of five, individuals can shorten the count or slow the pace of the walk. Individuals in good shape may be able to extend the count. Initially, diaphragmatic breathing may not come naturally, but it will become automatic with practice. Stop and place the hands over the head if short of breath when walking. Breathe in and out deeply and evenly until breathing returns to normal.

Can participating in a favorite sport several days a week help individuals trying to get fit or maintain a certain level of health?
Sports For Fitness
Spending hours in the gym can sometimes feel like a chore, especially for individuals who prefer competitive or recreational sports over traditional cardiovascular and resistance training. Various sports activities require only time, energy, sufficient apparel, and the willingness to play. Here are a few sports for fitness that can help improve overall health and wellness.
Cycling and Mountain Biking
Cycling is one of the best sports for fitness. Whether on roads or trails, fast or slow, it is a fantastic aerobic workout and benefits the leg muscles, specifically the quads, glutes, and hamstrings. Research has shown that, especially for those with diabetes, cycling can lower the risk of premature mortality. (Mathias Ried-Larsen et al., 2021)
There are appropriate bikes for all ages and stages.
Beginners start with paved trails.
Intermediate to advanced levels can engage in road cycling and mountain biking.
Road or mountain bike races for individuals looking to compete.
Racket Sports
Racket sports players range from all ages and fitness levels, entry-level to highly competitive, and all provide intense workouts.
Racket sports target the muscles in the back, shoulders, arms, chest, quads, glutes, hamstrings, and core.
Racquet sports have also been shown to lower the risk of cardiovascular disease mortality. (Pekka Oja et al., 2017)
Combine that with the endurance, speed, balance, and agility required to compete, and individuals will quickly see how these two sports can give a phenomenal workout while also burning a ton of calories.
Golf
For golf to be a fitness sport, individuals must walk all the holes while carrying or pushing the clubs.
What is needed is a supportive pair of shoes.
Walking the course can have multiple health benefits, including cardiovascular and respiratory health. (A. D. Murray et al., 2017)
Golf is a sport individuals can participate in at any life stage.
Water Sports
Paddleboarding, rowing, kayaking, and canoeing can provide a fitness solution for individuals who enjoy the outdoors. These sports increase heart rate, improve muscular endurance and strength, and burn serious calories. (Thomas Ian Gee et al., 2016)
Swimming
Activities that require upper and lower body muscles to work together rank high in sports for fitness. Swimming is the perfect full-body workout for anyone looking for an intense and competitive outlet that requires strength and endurance.
Swimming can be a year-round sport with various levels of competition.
Triathlon Training
Triathlon training is for lifelong athletes looking to improve endurance and strength and exercise beginners who need a goal; it is the ultimate sport for fitness.
Running, biking, and swimming together challenges every muscle and significantly increases aerobic and anaerobic fitness. (Naroa Etxebarria et al., 2019)
There’s something for every fitness level, from short sprint competitions to full Ironman events.
Basketball and Volleyball
Basketball and volleyball offer the physical benefits of a hard workout. These sports require sprinting, pivoting, and jumping, which engages the cardiovascular system and strengthens every muscle. Playing volleyball in the sand makes the muscles work harder.
Both sports are appropriate for most levels of fitness.
Beginners are recommended to learn the basic skills and go through drills before moving to games or matches.
Both sports require constant movement, increasing the risk of injury, so it is important to learn the fundamentals.
Talk to a healthcare provider before starting a new exercise routine or adding a new activity to an exercise regimen.

For individuals training for long distance walking marathons and/or events, can focusing on building a walking foundation, then increasing mileage progressively help condition the body for overall readiness?
Long Distance Walking Training
Training helps individuals be comfortable and safe for long-distance walking and events.
Training should focus on building a walking pace and increasing mileage gradually.
Individuals need endurance, not speed, and want to build mental stamina for walking for hours at a steady pace.
To reduce the risk of training injuries, increasing the total mileage per week/the distance of the longest walk per week to no more than 10% is recommended.
Individuals should also train to wear the gear worn during long-distance walks.
Training could last a few months.
Being methodical allows the body time to repair and build new muscle, blood supplies, and endurance.
Example Training Plans
Following a marathon training plan for mileage building and determining the proper hydration, nutrition, and gear for multi-day walks and treks is recommended. However, individuals must build back-to-back long days into their training sessions to assess any issues or problems resulting from walking long distances on back-to-back days.
Example Walking Training Plans
Multi-Day Walks/Treks Training Schedule
13 miles per day/21 kilometers
Use this plan for marathons or other multi-day walks with hills and natural surfaces requiring a backpack.
Training to Walk a Marathon
26.2 miles/42 kilometers
This will condition the body to go longer distances.
When training for distances of 31 to 100 miles/50 to 161 kilometers, the longest distance to train should not need to exceed 20 to 25 miles,
These should be performed at least twice two months before the marathon or event.
Taper down the month before the event to a 12.4-mile/20-kilometer distance.
Gear
All clothing, shoes, sunscreen, backpacks, etc., must be tested on the longer training days before the event.
Given the climate and terrain, plan for what will be needed and removed.
Try things out, as individuals don’t want to be surprised with something unfamiliar at the event. From head to toe, test the gear, including:
Shoes/boots, socks, underwear, bra, shirt, pants, hat, jacket, and rain gear.
Choose shoes or walking boots and wear them on long training days to break them in and ensure they perform.
Backpacks should be tested on longer training days to ensure they can be carried comfortably over long distances and have the necessary capacity.
Choose wicking fabrics that allow the skin to breathe and cool, especially under layers. (Justin De Sousa et al., 2014)
Individuals will want to wear gear similar to marathon walkers if the walk will mostly be on pavement or asphalt.
Individuals can modify their gear if the route is off-road or during different seasons. Find out what other long-distance walkers have worn on the same route or event.
Individuals can connect with fellow walkers via social media or find answers to frequently asked questions on the event’s or destination’s website.
Individuals can also contact the event director via the website or social media.
Nutrition
Proper sports nutrition will prepare the body for endurance activity.
For example, individuals are recommended to follow a diet comprising 70% carbohydrates, 20% protein, and 10% fat.
Avoid high-protein diets, as they can cause hydration problems and strain your kidneys under endurance walking conditions. (Marta Cuenca-Sánchez et al., 2015)
Train with the water, sports drinks, food, and snacks taken to the event, and do not deviate from them during the event.
Water is needed for 20 kilometers and under events, but an electrolyte replacement sports drink may be better for longer walks.
Diluting or leaving out some sugar can be easier on the stomach.
Have snacks pre-packaged and labeled for the times to be eaten.
Individuals need to eat fat and protein for ultramarathon distances – this can come from trail mix, peanut butter sandwiches, and chocolate bars with nuts.
Carbohydrates can be provided by sports gels or energy bars.
It is recommended to avoid products made for short distances and power sports as they can cause digestive problems when walking longer distances.
Planning a Walk
Planning begins by setting goals. Considerations include:
Time of year
Distance
Transportation to the event
Event pace requirements
Altitude and hill profile
Climate
Individuals are recommended to:
Prepare by researching routes and trails.
Study the course maps to know what services are provided along the way and what individuals must bring.
Walk a long distance without a supporting event.
Contact individuals who have walked the course.
Know the terrain and areas of total sun, hills, pavement, natural trails, and shade.
If possible, drive the course to become familiar with it.
Individuals may be able to find apps designed for their route.
Taking Breaks and Resting
Regular breaks should be short – using the bathroom, eating a snack, rehydrating, tying shoes, or bandaging blisters.
The body can stiffen up quickly during breaks and take several minutes to regain walking pace after a long break.
Recommendations could be taking a walking break instead, which means continuing to walk but at a very slow pace.
Foot Care
Individuals will have found what works for them concerning shoes, boots, socks, etc., on the long training days to prevent blisters and injuries. It is recommended to try different strategies, which include:
Sports tape
Blister block pads
Sprays
Lubricants
Wicking and/or double-layered socks
Moleskin
Stop at the first sign of irritation along the walk and doctor the foot with tape, blister bandages, or whatever method works best.
The body was built for walking. Planning and training properly before taking a long-distance or multi-day walk will ensure a safe and enjoyable marathon.

For individuals starting to lift weights, motor units are important for muscle movement. Can building more motor units help build strength and maintain muscle mass?
Motor Units
Motor units control the skeletal muscles and are the force behind every body movement. (C J. Heckman, Roger M. Enoka 2012)
This includes voluntary movements like lifting weights and involuntary movements like breathing. When lifting objects and weights, the body adapts to motor unit needs, meaning that individuals must consistently increase the weight to progress.
Lifting weights regularly trains the body to generate more motor units and force.
General guidelines recommend lifting weights for all muscle groups two to three non-consecutive days a week.
Consistency helps maintain muscle mass.
Regular progression increases the risk of plateauing.
What They Are
Exercise increases the body’s muscle strength, while sedentariness and inactivity weaken them. A motor unit is a single nerve cell/neuron that supplies the nerves to innervate a group of skeletal muscles. The neuron receives signals from the brain that stimulate all the muscle fibers in that particular motor unit to generate movement.
Muscles comprise different fiber types.
They are attached to the bones with connective tissue, which is stronger than the muscle.
Multiple motor units are dispersed throughout the muscle.
The motor units help ensure muscle contraction force is evenly spread throughout the muscle.
Motor units are different sizes and operate differently depending on where and what they do.
Small motor units might only innervate five or ten fibers. For example, to blink or sniff.
Large motor units can comprise hundreds of muscle fibers for swinging or jumping movements.
How They Work
The number of units activated depends on the task. Stronger muscle contractions require more. However, fewer units are needed to accomplish the movement for individuals expending less effort.
Contraction
Once a unit receives a signal from the brain, the muscle fibers contract simultaneously.
The force generated depends on how many units are required to accomplish the task. (Purves D. et al., 2001)
For example, picking up small objects like a pen and paper requires only a few units to generate the force needed.
If picking up a heavy barbell, the body needs more units because more force is needed to lift the heavier load.
The body can generate more force with stronger muscles.
This happens when lifting weights on a regular basis and overloading the muscles with more weight than they can handle.
This process is known as adaptation.
Adaptation
The purpose of lifting weights is to challenge the muscles so they adapt to the new challenge and grow in strength and mass. Motor units are a major part of the adaptation process. (Dr. Erin Nitschke. American Council on Exercise. 2017)
As individuals continue working out, their ability to generate more force increases and units activate more rapidly.
This makes movements more efficient.
Individuals can increase motor unit recruitment by consistently increasing the weight challenge to their muscles.
The development creates movement memory.
A relationship between the brain, muscles, and motor units is established even if the individual stops working out. The pathways are still there no matter how long the individual takes off.
When returning to training, the body will remember how to ride a bike, do a bicep curl, or squat.
However, the muscles will not have the same strength as the strength needs to be built back along with endurance that may have been lost.
It is the movement memory that remains.

For individuals who have decided to start exercising for fitness and health, walking is a great place to start. Can planning a walking exercise schedule help individuals maintain a fitness routine and improve endurance and speed quicker?
Walking Exercise Planning Schedule
While any amount of walking benefits health, individuals can increase the benefits by walking more per week or by increasing the pace. Brisk walking for 30 minutes per day, totaling 150 minutes per week, is recommended by health experts to decrease risks for heart disease, stroke, diabetes, and other conditions. (Centers for Disease Control and Prevention. 2022)
Individuals with ongoing health conditions should talk to their doctor before starting any new exercise program.
Beginners are encouraged to focus on using proper walking posture and technique to steadily improve strength and endurance.
The increased duration or intensity can help if weight loss is a goal.
Improving diet is also necessary for the best results.
Individuals can build healthy walking habits by tracking walks.
Schedule
Checklist
Individuals can walk outdoors, indoors, or on a treadmill.
Wear proper athletic shoes and clothing.
Check walking posture.
Walk at an easy pace for a couple of minutes before picking up speed.
First Week
An example of what a walking exercise schedule can look like, but it’s advised to consult a professional trainer to develop a personalized fitness plan.
Start with a 15-minute walk at an easy pace.
Walk five days the first week.
Building a healthy habit is the goal, so consistency is important.
Spread out rest days, like making days 3 and 6 rest days.
Weekly goal – 60 to 75 minutes
Second Week
Add five minutes, so the walk time increases gradually.
Or, individuals can extend more on some days, followed by a rest day.
Weekly goal – 80 to 100 minutes
Third Week
Add five more minutes with each session, so the walk increases to 25 minutes.
Weekly goal – 100 to 125 minutes
Fourth Week
Add another five minutes to increase the walk to 30 minutes.
Weekly goal – 120 to 150 minutes
Individuals who find any week to be difficult are suggested to repeat that week instead of adding time until they are able to progress naturally. Once able to walk for 30 minutes at a time comfortably, individuals are ready for a variety of different walking exercise workouts to add intensity and endurance. A weekly walking plan can include:
Longer walks
Higher-intensity walks
Speed-building walks
Beginner Walking Speed
An individual’s objective should be brisk walking to achieve a moderate-intensity workout. This is the intensity that is associated with the most health benefits.
