What happens in Abdominal & Hip Flexor #1 Inverted V Stretch?

• A. Hands on footbar, heels against lumbar support. Move between arched/rounded spine and carriage in/out. Variations include heels down, external rotation, large ROM, and metatarsal position.
• B. The exercise is performed with the heels on the footbar and no movement of the carriage.
• C. The spine must stay neutral throughout with no arching.
• D. Hands off the bar while the carriage moves in and out.

Answer: (A)

This exercise tests coordinated spinal articulation with carriage movement on the reformer. With the hands on the footbar and the heels pressed into the lumbar area, you create a stable setup that allows the carriage to travel while you move your spine between an arched position and a rounded one. This combination forces the core to stabilize the pelvis while the hip flexors lengthen, giving a controlled stretch through the front of the hips and an expressive range of motion through the spine. Variations—heels down, external rotation, a larger range of motion, or placing the feet on the metatarsals—adjust leverage and intensity without changing the fundamental pattern of arching and rounding as the carriage moves. Keeping the hands off the bar, or restricting movement of the carriage, or insisting the spine stay neutral with no arch would not deliver this dynamic, integrated stimulus.
