Muscles trained: Hamstrings, glutes
Grab a pair of dumbbells and stand holding them at arm's length in front of your thighs. Keep your feel shoulder-width apart, your knees slightly bent, and your eyes focused straight ahead. Slowly bend at the hips as you lower the dumbbells just below your knees. Don't change the angle of your knees. Keep your head and chest up and your lower back flat or slightly arched. Lift your torso back to the starting position, keeping the dumbbells as close to your body as possible.
