What's the Best Lower Body Exercise? Squat!
When done correctly the squat works almost all muscles of the lower body! And by applying different variations you can incorporate just about the entire body. Bringing arms out in front adds work to your shoulders and core, adjust your foot placement and target the inner thighs, add an overhead press and almost every muscle in your body is worked. There is a reason that the squat is called the "King" of all exercises.
