Forget about the floor! Get the fab abs you desire without hitting the mat, thanks to this move created by Alwyn Cosgrove, owner of Results Fitness in Newhall, California. His theory:

"The abdominals are spinal stabilizers, so they respond better to work done standing versus lying down. On your back, the spine is supported, taking the workload off the abs."

How to do it:

Stand with feet hip-width apart, knees slightly bent, hands clasped behind head and elbows pointed out to sides. Lift right leg to side, knee bent, thigh parallel to floor. Keeping knee lifted, bend torso to right side, bringing elbow and knee toward each other (as shown). Do 10 reps; switch sides; repeat.
