Exercise of the Day - Alternating Crunches on Exercise Ball

Unlike a standard Exercise Ball Crunch, this movement requires the activation of more core muscles, including the obliques, thus making it a much more effective exercise.

Alternating Crunches on Exercise Ball

The most common mistake with this exercise is bringing the upper body off of the ball and then twisting to one side or the other. You will recruit more muscle fibers by twisting as you come up, reversing the twist on the way back down, and then doing the same movement on the other side. Also, when in the top most part of the movement, hold that peak contraction for one or two full seconds before returning to the bottom position. Come back up from the bottom position immediately, though - do linger there and rest.
