Do you do anything particular for your shoulders, thats something that I need to work on. I usually only do body weight exercises but its hard to find enough body weight exercises to do for your shoulders so I just end up using some dumbbell exercises. But this is my summer routine so far, with only a very few dumbbell exercises. I included some warm ups and moves from Jiujitsu, the martial art I am practicing. The punching routine is a series of punches commonly used in martial arts.

I'm gonna do this every other day for the rest of the summerbefore I eat and then have a whey protein shake. If you workout after you eat you are just burning calories that you just intook. If you eat after you workout the protein goes right to where its needed (your muscles) instead of just being stored as fat. On the other days I am just going to do the workout I did during the school year that I already posted (50 crunches, 15 push ups, and 10 pull ups) along with 25 squats.
Maybe its a bit of overkill but I do not gain muscle easily as I am an ectomorph.
