Believe it or not, one of my favorite ab exercises uses one of those cheap infomercial gadgets, the “Ab Wheel.”
You can pick one up at Amazon.com or Wal-Mart for under 20 bucks, and it works your abs hard without having to do crunches.
But what about the other ab gadgets you see advertised on TV?
Researchers (from the Mayo Clinic, of all places) tested the “Ab-Slide”
(a contraption that’s similar to the Ab Wheel), and compared using it to doing ab crunches, supine double-leg thrusts (seated knee tuck-ins), and side planks.
Ten young men and 12 young women did all the exercises. And the researchers found that the Ab-Slide worked the abs the hardest. On the other hand, the seated knee tuck-ins required a lot of hip flexion, and they believed it could cause problems in people prone to low-back injury.
Personally, I’m going to stick with the Ab Wheel. As always, I’m going to keep crunches out of my program… and now I’m going to add the seated knee tuck-in to my list of ab exercises to avoid.
