Which muscles are primarily engaged in the supine arms in straps series?

The supine arms in straps series primarily engages the transverse abdominis, hip flexors, latissimus dorsi, and long head of the tricep. This exercise is designed to challenge the core stability and upper body strength.

The transverse abdominis acts as a stabilizer for the spine and pelvis, providing support during the movements. The hip flexors assist in maintaining proper alignment and control of the pelvis while the legs are engaged. The latissimus dorsi, a large back muscle, plays a crucial role in arm movements and stabilization of the shoulder girdle during the exercise. Meanwhile, the long head of the tricep is involved in the extension of the arms, enhancing overall strength and coordination.

This combination of muscles helps facilitate efficient movement while promoting core stability and upper body control, important elements in Pilates practice.
