Pour rappel concernant les crunches:
"The Pilates roll-up is 30 percent more effective than the standard crunch when it comes to targeting the rectus abdominis (the "six-pack" muscle), say researchers at Auburn University in Montgomery, Alabama. Because the move challenges your abs through a fuller range of motion, it recruits more muscle fibers.
Try it:
Lie back with legs straight and arms extended above head next to ears.
Bring arms forward, tilt chin down, and slowly curl upper body up, reaching hands to toes.
Repeat 8 to 10 times three times a week."
