Our Top 10 Abs Exercises

Abdominal Hold

This is the sort of move that looks so wonky, you sure hope your roommate doesn't catch you doing it -- unless she also gets to see you look stellar in a bathing suit, in which case she just may pull up a chair.

Do it:

• Sit tall on the edge of a sturdy chair (or step with four risers) and place your hands on the edge with your fingers pointing toward your knees.
• Tighten your abs and bring your toes 2 to 4 inches off the floor. Lift your butt off the chair.
• Hold this position for as long as you can -- aim for 5 to 10 seconds.
• Lower yourself down and repeat.
• Continue this exercise for 1 minute.
