Do this drill preferably on a multiple-angle box or similar apparatus, which you must securely attach to the ground so it does not move or slip while you are performing the hops. The angle hops improve balance and lateral movement. This drill is useful in Alpine skiing, tennis, football, and gymnastics, as well as other sports.
Stand in a relaxed position on one angled surface of the box
Hop laterally from one side of the box to the next sequentially, emphasizing a rapid side-to-side motion. Once skill has improved, progress to more distant angles. Block with the arms for balance.
