Debunking an Exercise Mythby Carole Phillips on 10/07/13
Myth: Don't let your knees go past your toes while doing a squat or lunge.
Reality: Avoiding excessive forward movement on the knee during a squat or lunge is important. However, in everyday activities such as climbing stairs, the knee and torso naturally move forward slightly in parallel with each other for balance and to propel the body forward and upward. Restricting this movement when performing squats and lunges increases hip stress and could increase the load on your lower back.
