April '25 Muscle of the Month: Bicep

Our April Muscle of the Month is the bicep! Formally known as the biceps brachii, it is a two-headed muscle located on the front part of the upper arm. The bicep connects the shoulder to the forearm and is primarily responsible for elbow flexion (bending the arm), forearm supination (turning the palm upward), and shoulder stabilization.

In Pilates, the biceps play an essential role, even though the Pilates is often associated more with core strength and flexibility than with traditional arm workouts. Many Pilates movements subtly engage the biceps, especially when performing exercises that involve resistance bands, light hand weights, or on the reformer machines.

For example, during movements like bicep curls on the reformer, plank to pike transitions, or arm circles, the biceps work in conjunction with other muscles to maintain control, form, and balance. Unlike heavy weight training, Pilates focuses on elongated muscle engagement, meaning the biceps are strengthened through controlled, low-impact movements that emphasize precision and endurance.

Strengthening the biceps through Pilates contributes to better posture, enhanced upper body strength, and improved functional movement, all while reducing the risk of strain or injury.
