text: For your legs:  biking, jogging, elliptical trainer, squats, dancing, kicking, stair climbing though not TOO much as you don't want bulging muscles.  They should just become firmer with all that exercise.\n\nFor your stomach:  Continue with the crunches but when you come up, turn to one side then down, then come up and turn to the other side. That will help develop your 'oblique' muscles in your abdominal section.\n\n Also, while you're on the floor, lift your head, put your hands behind your neck and lift your legs with your knees bent.  Now move your legs like you're pedalling a bike and alternate pointing your right elbow to your left knee when it's up, then your left elbow to your right knee.  \n\nKeep up the good work with the pushups but remember that your arms have other muscles so lift heavy objects and pull too.
