Position yourself for this exercise by standing upright in front of an elevated platform with a dumbbell in each of your hands (your palms should be facing your outer thighs). Place your right foot on the platform and step onto the apparatus by extending the hip and knee of your right leg. Press primarily through your heel in order to lift the rest of your body up in elevation until you are able to place your left foot onto the platform as well. Once both feet are on the platform, step down with your left leg by again flexing the hip and knee of your right leg. Finally, return to the starting position by placing your right foot next to the left foot back on the ground. Repeat for the prescribed number of repetitions on your right leg before switching sides and performing the prescribed number of repetitions with your left leg. Alternatively, you can switch which leg you step up with after every repetitions (in alternating fashion).
