Place barriers 4 feet apart. When you first start you want to go slow so that you get the correct movement pattern and technique. You may have to do this a few times the first session. Then work on speed over the next few sessions. Once again, you may have to do each exercise a few times. Once you have mastered speed and technique you only need to do each exercise once, (unless you trip or feel you need to do it again). Editor's Note: Barriers will be available soon from our store. If you don't have any kind of physical barrier, you can still benefit from this workout by jumping over lines of tape, or some other marker.
