Pilates Moves Recruit Deep Abs Better Than Crunches

Pilates professionals can confidently promote the effectiveness of certain Pilates exercises to target the deep abdominal muscles (i.e., the internal obliques and transversus abdominis), resulting in aesthetic improvements and functional benefits, says a recent Pilates study presented at the 55th Annual Meeting of the American College of Sports Medicine (ACSM), held in Indianapolis. Particular Pilates moves that involve less flexion recruited the deep abdominal muscles more efficiently than standard crunches.

Researchers recruited 12 participants—10 women and two men—to perform 10 repetitions of the Pilates hundred, roll-up and double-leg stretch, along with 10 standard crunches, and the investigators measured muscle activation. The exercises with the least flexion, the hundred and the double-leg stretch, featured the highest recruitment of the internal obliques and the transversus abdominis. Consistently performing exercises that train these muscles translates into a leaner, flatter appearance of the stomach, better support for overall movement, and a stronger back, according to lead researcher and IDEA author Michele S. Olson, PhD, FACSM, at Auburn University in Montgomery, Alabama.
