Get the Most Out
of your Crunches
The sit-up vs. crunch
debate raged
on for years, followed by a plethora of new ab products, all in an
effort
to get you a stronger, flatter stomach without putting pressure on your
lower back. For now, it seems, the debate has reached an end with
a nationwide consensus of trainers. A survey of over 3000
ACE-certified
trainers* concluded that the best ab exercise is the Crunch on a Swiss
Ball.
Position yourself on a
Swiss Ball
so it supports your back and with your feet on the floor. Curl
up,
hold, then return to starting position. This makes it very
difficult
to cheat and requires your core-stabilization muscles to
contract.
This means fewer reps than regular crunches can get you better results.
