During Arm Circles, you lie on your back on the Reformer while holding the straps or handles. With the assistance of the springs, your arms move in large circular patterns from shoulder width down alongside the body, up overhead, and back to the starting position. This controlled movement requires continuous muscular engagement, strengthening the shoulders, arms, and core muscles.
Benefits of Practicing Arm Circles on the Reformer
Pilates Arm Circles on the Reformer offer numerous benefits for both physical performance and body awareness. Below are some of the key advantages of this exercise:
1. Improves shoulder flexibility
The Pilates Arm Circles exercise on the Reformer helps enhance shoulder flexibility by gently stretching and warming the muscles surrounding the shoulder joint. Circular arm movements maintain and expand the shoulder’s range of motion, which is essential for preventing stiffness and reducing injury risk.
2. Strengthens the upper body
While performing Arm Circles, the shoulders, arms, and chest must work continuously to maintain control and stability. This helps build upper-body strength, improves muscular endurance, and supports everyday functional movements.
3. Enhances core stability and control
Arm Circles do not only target the shoulders and arms; they also require active core engagement to maintain balance and control on the Reformer. This improves core stability, supports spinal alignment, and contributes to better overall posture.
