PUSH-UPS and SIT-UPS

Fitness entrepreneurs peddle equipment that magically reduces body fat and builds muscle for only 13 payments of $499. What they fail to mention is you already possess the best piece of fitness equipment ever designed: your body.

Sit-ups and push-ups will tone your body and at absolutely no charge. A simple change in push-up hand position tones arms, chest or shoulders. A slight adjustment in sit-up position strengthens your whole core. And next time you see one of those infomercials, think about the last time you heard a drill sergeant scream, "drop and give me 20 reps on the Bow Flex!" {relatedarticles}

SQUAT THRUSTS

Take push-ups to the next level with squat thrusts: Begin in the standing position. Squat. With your hands on the ground, kick your legs back to the push up position. Return feet to squat position. Stand up. Repeat.

Squat thrust benefits include strong legs, shoulders, chest, arms, abdomen, and buttocks. They improve cardio vascular health, can be done in conjunction with other exercises and make a great old-school aerobics workout.
