Bicep Curls: El Paso Back Clinic

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.
• It can be done standing or sitting.

Avoid Errors

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.
• Take a thorough rest before the next set.
• Stop if pain begins to present.

Benefits

• 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.
