"The squat is perhaps the most effective weight-training exercise for total-body development...The legs may be moving the body, but it takes a stable trunk and strong upper body to provide a foundation in which the legs can produce force. This is especially true when you start adding weights to your squats. Whether it be a back squat, front squat, split squat or overhead squat, many muscles of your whole body work in concert in order to lower and raise your center of gravity."
