Cinch an Inch Faster
To give your obliques all the waist-whittling benefits of a bicycle crunch, freeze your legs in mid-spin, says Adrienne Howell.
- Lie faceup with right arm extended out to side, palm on ground, and left hand behind head.
- Lift left leg 6 inches off ground and bend right knee 90 degrees so shin is parallel to ground. Bring left shoulder toward right knee.
- Keeping left leg elevated and right knee bent, lower torso.
- Do 15 crunches.
- Lower legs. Switch sides; repeat.
