One foot on the tail, (by foot I mean the ball of the foot which is just behind the big toe) the other foot is about an inch behind the bolts(screws) for the front truck. Basically, the back foot quickly pushes the tail down, and right when the tail of the board strikes the ground, the back foot jumps up… the tail of the board will follow up with the foot when the front foot slides forward slightly, which pivots the tail of the board upwards. Since the front truck comes off the ground first, getting the back truck up is the trick.
The ollie is a skateboarding trick where the rider and board leap into the air without the use of the rider's hands. It is basically the combination of popping, sliding, and jumping on the skateboard all at the same time. Originated in vertical skateboarding, and later on flat ground, it is not intuitively obvious how the liftoff is achieved, making the movement visually striking.
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.
