Toned you say? First of all, girls get toned. Guys get muscular. I'm guessing when you say you want to get "toned" you mean bigger muscles, less body fat, etc. Well yes, pushups are a compound exercise that work your entire upper body. They'll work your pecs, triceps, shoulders, and even your lats to a certain degree during the eccentric (lowering) phase of the lift. But the key to gaining muscle is more than just exercise, you have to eat properly to supplement your growth.
