Grab one or two dumbbells and hold them in front of your thighs. Soften your knees, hinge forward at your hips and keep your back straight as the dumbbells lower toward the floor. Go down as far as you can maintaining a straight back. Rise back up to standing. Repeat.
We love these adjustable dumbbells from Rep Fitness. They take up very little space and are also very durable compared to other adjustable dumbbells on the market.
