HOW: Begin this exercise with your feet spread apart beyond hip-width. Lunge towards the desired leg to exercise, lower yourself as far as you feel comfortable then push into the floor to return back to starting position. Avoid placing the weight excessively on your forefoot or your heel, keep most of the weight in the middle of your foot. The wider the feet, the deeper you will be able to lunge.
FEEL: The leg that you are lunging on will be working, from the calves up to the thigh and hips. You may feel a stretch in the groin on the side of the leg that is straight.
COMPENSATION: Avoid letting the knee going too far forward past your toes, this should be a combination of hip and knee bending. Also, avoid your knee caving inward, make sure to keep your ankle, knee, and hip in alignment.
