THE FLAT-ABS MOVE TO DO: THE SUPERMAN
1. Lay on the ground facedown with your arms and legs extended.
2. Start by lifting your upper body and lower body off the ground then back down again. Once you get stronger, try to go up and down without touching the ground. Do 10 to 20 reps for three sets. This is the perfect exercise for new moms because it pulls the body back, lengthening the midsection.
