Two things to concentrate on and take ownership;
2. Landing quiet
Do a set of four around the compass and rest. Do it again as you feel more comfortable with it. Work up to 3-4 sets at a time. You can reverse the direction (go left) the next time. Form is what you look for..every time.
Land softly in a squat position and absord the impact. Anticipate landing soft and feeling the ground catch you. Try and land on your midfoot to the balls of your feet.
Once you master the four directional hops you can move on to "half hops" which will be jumping from north to south in one move. This will require more explosion and demand more balance.
