How to do it
- Kneel with the front foot flat, front shin vertical, and the rear knee on a small pad.
- Keep the torso upright and rest both hands on the hips.
- Squeeze the glute on the kneeling side and tuck the pelvis slightly.
- Shift the hips forward until you feel a stretch in the front of the rear hip.
- Rock back to the stacked start without losing the glute squeeze.
- Finish the reps, then switch the kneeling knee.
Common mistakes
- Arching the lower back to fake a bigger stretch.
- Letting the rear glute go quiet so the hip flexor never lengthens.
