Stand on a box about 2 feet high to start. Step off and land on both feet simultaneously.
Immediately upon landing, without any false step, decelerate and sprint left
or right 90 degrees or straight for 10 to 20 yards.
As your balance and leg power improve, you will be able to get into the sprint
quicker. According to your strength gains, gradually increase the box height.
Complete 8 to 10 repetitions, alternating the direction of your sprint between
left, right and straight ahead. Rest one full minute between reps.
