Abs Matrix

Start by holding two five-pound dumbbells at your shoulders, balancing on your right leg with your left foot slightly off the ground. Perform all three steps, then switch legs and repeat.

1. Do a shoulder press with your right arm while you lean your body back slightly — press upward from slightly behind your head. Return to an upright position. Repeat with your left arm.

2. Do a shoulder press with your right arm while you lean your body back slightly. Push the weight up and out about 45 degrees to the side, and slightly behind your head. Return to an upright position and repeat the move with your left arm.

3. Lean back and press your right arm across your body to the left, just above your left shoulder. Return to upright. Lean back and press your left arm across your body to the right.
