Olympic Swimmer Dara Torres' Moves for Rock Hard Abs
Start in push-up position with hands shoulder-width apart. Keeping elbows tight in at sides, slowly lower chest toward ground; push back up. Do this very slowly, to feel stretch across chest. And keep body flat, like a plank, pulling belly button in toward spine (don't let belly sag).
Do 3 sets of 5 to 10 reps.
