Pilates 100s

To firm up the muscles beneath your love handles — known as the external obliques — try the Pilates "100s." This exercise was found to challenge more overall muscle in one shot (specifically, the muscles spanning the waist) than traditional crunches. To do the 100s, sit on a mat and make a V with your body (your butt forms the bottom of the V). Reach your hands past your knees, arms parallel to the floor. Pump your arms up and down 100 times, inhaling and exhaling every five counts. via
