Stand about two feet in front of a bench or step with your back to it. Hold a dumbbell in each hand by your sides and place the top of your back foot on the bench. Keep your front foot firmly planted on the ground, with your knee slightly bent.

Slowly bend your front knee to lower your body toward the ground, allowing your back knee to drop toward the floor. Lower until your front thigh is parallel to the ground, or as far as your mobility allows.

Press through your front foot to extend your leg and return to the starting position. Repeat for the desired number of reps before switching legs.
