The skater can gain greater clearance from the ground by jumping higher, popping faster, sliding the front foot farther forwards (starting the jump with the front foot farther back), and pulling the legs higher into the chest to raise the feet higher. Skaters attempting record-setting ollies even contort the legs so that board and feet are not directly below them, allowing the board to rise at or just below the level of the pelvis.
But, a quick warning! If you learn to ollie while standing still, you can develop some bad habits. Some skaters end up turning in the air a little, and not landing straight. You might not even notice until you try to ollie while rolling. So, if you practice while standing still, I highly recommend also practicing while rolling. Maybe only practice in one spot for a few days - maybe a week or two - and then give the rolling ollie a shot. That way, if you are developing bad habits, you can shake them off before they really mess you up.
Smile and wave – Feel free to look around at all the other people at the skatepark that stood by and marveled at your new-found accomplishments (all one of them). I’m sure by this point you’ll be picking up roses that are being thrown at your feet, and taking a well-deserved bow as they begin to chant your name. Take it all in, thank the crowd for their undying affection, and then go get a snow-cone. You deserve it, champ.
