It is correct to avoid excessive forward movement of the knee during squatting and lunging movements. It is a myth, however, that you should “never let your knees go past your toes while doing a squat or lunge. ” This belief originated from a study that is more than 30 years old (1978 Duke University study that found maintaining a vertical lower leg as much as possible reduced shearing forces on the knee during a squat). The truth is that leaning forward too much is more likely what is truly causing the problem or injury. - See more at: http://cuttingcyclesteroids.tumblr.com/post/85898248065/knee-movement-proper-form-during-lunge-exercises#sthash.ytWjDGJM.dpuf
