#3 – Exercise Ball Side Crunch

A variation on the standard ball crunch, this allows you to target your obliques, the diagonal muscles that feed into your abs from the side. The arc of the ball allows you to stretch your obliques at the start of the exercise, increasing the range of motion to make your obliques contract harder.

Lie on your right side against the exercise ball, arms positioned as above, legs extended and feet apart for balance. Slowly raise your body towards your left hip, breathing out and pausing in the top position before slowly lowering yourself down to the start position whilst inhaling. Repeat on the other side once the set is completed.
