Wheelbarrow Push-Up

Tones chest, shoulders, triceps, glutes, and abs

This buddy push-up works more muscles than the solo kind. As a result, you have to really tighten your abs and buttocks muscles to keep your body straight.

Assume the push-up position with hands directly beneath shoulders and back straight. Have your partner squat down using good form (back straight, knees behind toes) and lift your legs as though holding a wheelbarrow. As she picks you up, tighten your glutes and abs to prevent your body from drooping. When you are steady, bend your elbows and lower your chest until your upper arms are parallel to the ground. Hold for a second, then push back up.
