Partner MB Twist
Sit on the floor back-to-back with your partner, keeping your legs slightly bent at the knees, heels on the floor.
Pass a suitable size medicine ball horizontally around both partners, with the initiating partner turning to the right, whilst the other partner grabs the ball on their left hand side, and then passing it back on their right.

Beginners aim for 10 - 15 turns each direction.
Intermediates work for 10 - 25 turns each direction.
Advanced aim to work for 10 - 25 turns each direction with feet 2 inches off the floor.
