There's so much you can do with bodyweight alone. The basics always come up for a reason: sit-ups, planks, push-ups. They'll always give you results. The way to take it up a notch is to compound the basics to work multiple muscle groups at once.

I really like battle ropes. They're so versatile; you can get a terrific workout doing a ton of different exercises with them. My clients like them because they're a good way to get aggression out, too. Had a bad day? Take it out on the ropes!

Even if you can't do a full real push-up, I'd rather have you do them with a limited range of motion and work up to the perfect pushup then do them on your knees, where you probably won't progress at the rate that you could.
