Step by step instructions
Stand with feet slightly wider than hips, holding a dumbbell in right hand. Pivot through feet, turning toes to the right and immediately lowering into a deep lunge, reaching right arm to the floor just outside of right foot.
Stand up and rotate body, turning toes to the left and lifting right heel off the floor as right arm bends into chest and then presses dumbbell overhead (arm should be slightly in front of head at the top), abs engaged. Return to starting position.
