What are the primary muscles engaged during the Long Spine exercise?

The Long Spine exercise primarily engages the abdominals and hamstrings. This exercise is designed to lengthen and articulate the spine while promoting core stability, which is crucial in Pilates practice. The abdominals play a key role in maintaining pelvic alignment and controlling spinal movement as the body transitions through the exercise. In conjunction, the hamstrings are actively engaged to help facilitate the articulation of the spine while also supporting the pelvis and lower back. Together, these muscle groups work effectively to create the desired length and control necessary for this exercise, emphasizing the core-initiated movement that is fundamental to Pilates. This focus on the abdominals and hamstrings enhances overall body awareness and stability, which are key objectives in Pilates training.
