"Several years ago, a scientist named McClaren conducted an experiment with two control groups. Group A performed only upper body exercises without squatting; Group B performed only squats. After a several months, Group B exhibited more overall muscularity than Group A. From this experiment McClaren concluded that squatting seems to affect the entire body not just the legs."
Do you have any additional pieces of information on his study/studies? This sounds more than interesting. Thanks a ton!!
