Short anwser: Yes. Long anwser: No, with a "but".

[Beefcake]

(yes to the last part anyway. It's been proven that you will gain overall size and bit more strength from squats. Not sure about calfs and hammies, but squats for sure will)

[CrusaderMuscle]

Doing squats will help increase your testosterone levels. Squats are probably the single most anabolic exercise.

[Teamorbit]

Hormone levels have shown to be at the highest during leg workouts than any other muscle group. During squats your incoporating so many muscles at one time.

[rIPPDUP]

working legs releases more natural testosterone than any other body part, another benefit is the natural release of gh jumps as well.
