Core Twist

Core Twist - works shoulders, back, abs, obliques and inner thighs



Lie facedown on ball with shins atop its center, placing palms on floor so that they align under shoulders, with arms extended (body forms a straight line from head to heels).

Engage abs and spread feet about 1 foot apart atop ball.

Keeping shoulders squared, slowly roll ball slightly to left and then right to complete 1 rep.

Do 15 reps.

Tip: To make this move easier, lie with thighs on ball.
