Breakthrough Belly Flattening Plan.4)T Plank.

Assume a full push-up position with arms extended and hands directly beneath shoulders. Hold for 10 seconds. Rotate body to right, allowing feet to naturally turn onto sides, and extend left arm toward ceiling. Keep hips lifted, so body forms a diagonal T (shown). Hold for 10 seconds. Return to start, and repeat to opposite side. That's 1 rep. Perform 2 or 3 reps.
