Place right foot on a box (or bench) at about knee level and hold a (relatively light) dumbbell in opposite hand. Step straight up and drive knee high to waist level. As your body raises, curl dumbbell. Return back to ground and starting position. Keep same foot on box and explode back up into another repetition.
