Stand up straight with a clear area ahead of you.
Have a tape or a line, and two markers.
Position one marker at the starting position.
Stand on one leg with your hands clasped behind your back with your toe in line with the first marker.
Perform 3 hops forward, aiming to hop as far forward as you can while keeping your balance.
Hold the final hop for a few seconds.
Place the second marker in line with your heel.
Repeat the exercise on your other leg and note the difference in distance between the two attempts, if any.
