Bobbi, what are your credentials in the fitness field? The hip flexors FLEX THE HIP. When analyzing movement during strength training, the joint action of the working muscles designates the primary movers in the exercise, and the hip flexors ARE NOT PRIMARY MOVERS in a lunge or a squat on the concentric phase (coming up from gravity). The hip flexors act to control the movement eccentrically (toward gravity) on the front leg, but they are not working as prime movers on either leg - the quads, glutes and hamstrings (to a lesser degree - every hear of passive insufficiency or would you like to debate that as well?) are the prime movers on the front leg, and the quads and calves of the back leg. You get brownie points for the statement about the adductors and abductors acting as stabilizers, which is correct.
Cathe states that during a static lunge, the hip flexors and quads of the BACK leg are working, and the hip flexors are not working (being strengthened as a prime mover). Yes, they are on stretch, but since there is no movement taking place at the hip joint of the back leg, they are not a prime mover in the exercise. In fact, if someone has tight hip flexor muscles, they can even be the weak link in a lunge.
I appreciate your concern for Cathe but you are incorrect. And I don't recall ever seeing any fitness related credentials in any of your posts. Care to share them with us?
