What happens in Pelvic Stabilization #7 Single Knee Pull?

What happens in Pelvic Stabilization #7 Single Knee Pull?

• A. Arms move while legs remain still.
• B. Both legs extend with pelvis stable.
• C. Knee pulls toward the hip while torso rotates.
• D. One foot works on the footbar while the other knee pulls toward the chest or holds tabletop. Press out and in without shifting the pelvis.

Answer: (D)

This exercise tests keeping the pelvis steady while isolating leg movement on the reformer. One foot stays on the footbar to provide a stable anchor, while the other knee pulls toward the chest or rests in tabletop. The carriage then presses out and back in without letting the pelvis shift or twist, so the movement comes from the working leg and the core stabilizes the pelvis. Why this fits best: it explicitly describes the stabilizing of the pelvis while performing a single-leg knee pull with the opposite leg anchored on the footbar, plus the out-and-in carriage action that reinforces control and alignment. Other options don’t capture the same setup or constraint: moving arms isn’t the focus here, bilateral leg extension without pelvis movement isn’t the single-knee pull with stabilization, and introducing torso rotation contradicts the intended stable pelvis during this exercise.
