High Lunge

Rectus femoris may contribute to the issue but is not treated as the complete explanation. Bending the back knee can compensate by reducing the amount of hip extension required. A high lunge combines front hip flexion with back hip extension. High lunge requires one side of the pelvis to open while the other side closes. Back knee bending in high lunge may reflect inability to create hip separation and pelvic dynamics rather than a knee problem. The general corrective strategy is to train maximal flexion of one hip with maximal extension of the other. Half-kneeling can serve as a regression because it preserves the pelvis-and-hip relationship while reducing standing demand.
