[Crpl. Crunch]

Well what i do is pick my main body parts- arms, legs, shoulders/back, and chest. And just train those on a certain day. Like with arms i'll do a set of curls then immediatly do set of a tricep exercise, making one Super set. I do that four times, then do that three more times with different exercises. Shoulders the same way, i try to hit all three heads of the shoulder. And so on and so on...Whatever you do, try doing supersets it'll get you done with your workout in half the time!
