Stand upright holding a dumbbell in each hand with your palms facing your legs and your knees slightly bent.
Keeping your arms straight and knees slightly bent, slowly hinge forward, bending at your hips (not your waist) to lower the weights to your shins.
Keeping your back almost parallel to the floor and your core engaged, bend your elbows and squeeze your shoulder blades together to row the dumbbells up next to your ribs.
Maintain the position of your torso as you lower the weights back to your shins.
Squeeze your glutes to return to standing, keeping your back straight. That's one rep.
