Get out of the sagittal plane to decrease muscular imbalances and asymmetries. The lateral lunge should be completed with the stepping foot landing forward, HINGING at the hips so the glutes are active. This is not a knees over toes movement, do not allow the front of knee to cross over your toes, hinge and keep your shoulders from rotating. They need to be in external rotation with the spine neutral. Best to program these after heavy bilateral lifts transitioning into more strength.
