“This fluid movement firms up flabby obliques, the muscles that cause muffin top,” says Denise Austin. To start: Kneel down on a mat and extend your right leg out to the side. (Steady yourself by drawing your belly button in towards your spine.) Hold a tea towel taut with both hands, and raise your arms overhead.
Then, keeping your abs engaged and your spine straight, slowly reach to your right side. Without pausing, return to the center, then reach to your left side. Don’t lean forward or back. Keep your torso upright while tightening your abs and squeezing your buttocks. Continue alternating sides for one minute.
