Rotational Dumbbell Straight-Leg Deadlift

Start: Grab a dumbbell in your right hand and hold it so that it hangs vertically next to your side. Stand on your left foot with your knee slightly bent. Lift your right foot off the floor and bend that knee slightly.

Movement: Without changing the bend in your left knee, bend at your hips, and lower your torso as you rotate it to the left and try touch the dumbbell in front of your left foot. Reverse the move to the starting position and repeat. On your next round, switch arms and legs.
