Avoid These Ab-Exercise Mistakes
Why waste time on moves that don't offer results? These tips will give you a tight belly the right way.

Time wasters
Are these do-nothing techniques a little too familiar? Ban them from your routine and you'll see results sooner:
Using momentum: Rocking your body back and forth will lessen the workload on your abs. Crunch slowly and with control.
Misplaced arms: Placing your hands behind your head and pulling your head and shoulders up will lessen the load on the abs, and can damage the neck. Place your hands by your ears and use the abs to curl up.
Ab cradles: This is the apparatus in the gym which supports your head and arms on a metal rocking frame. The problem again is that momentum and pulling with the arms will lessen the load on the abs, so work slowly and keep your arms and hands lightly resting on the supports.
