Crunch & Punch

Crunch and punch - works the abs & arms

 

Lie with mid- and lower back on a stability ball, feet shoulder-width apart, knees bent and hips level with knees. Place hands behind head, elbows wide. Lift left shoulder blade off ball and punch left arm over right hip (as shown). Return to start position and repeat to other side. Do three sets of 10 punches to each side.
