Hold a dumbbell in your right hand. Step your right leg back and hinge forward from your hips, allowing your left knee to bend slightly. Rest your left arm on your upper thigh. Your spine and head should be in a neutral position.
Engage your core, relax your shoulders, and extend your right arm forward and down to the floor.
On an exhale, pull the dumbbell up with control, driving your elbow straight back and keeping close to your ribs.
On an inhale, lower the dumbbell back down to the starting position. That's one rep.
