I find that push ups are enough...although I can only squeak out 4 or 5 real push ups, even though I've been working on them for months now. I figure I'll stick with the wimpy girl pushups and throw in a few guy pushups. Anyway, they work everything, so I'm happy. I'm also a big fan of yoga. Yoga gives you nice shoulders. Now if I could just get that yogabutt, I would be really happy.
