Ollie - Is basically jumping up. Your back foot has to be on the tail of the board. In this move you place your front foot as close or as far from the back foot as you want. The closer to the foot, the higher the jump. Press down hard with your back foot. At the same time you press down slide the front foot to the very front of the board. Then straighten out and land.
Kickflip - In this keep your back foot on the tail and the front foot in the low center, kind of on the side. Jump like an ollie, except instead of slide your foot up, kick your foot out to the side that your foot was hanging from.
Pop Shuv-It - It is done like an ollie except move your front foot about an inch behind the screws. Then ollie while you are in the air kick back foot forward and front foot back. Then bring your foot back over the board and land! You have done a Shuv It!!!
Heel Flip - Have your feet placed like your going to do an ollie, except place your front foot so all your toes hand off the board. The ollie and kick your front foot the way your toes point. Then try to stay above the board then land it. That's a heel flip.
