How to do an ollie
Step 1- put your index finger on the middle of the board and your pointer on the tail.
Step 2- Now that you have your fingerplacement,practise kicking the back of the board.
Step 3- Kick the board and slide your index finger to the front of the board, when its in the air straighten the board out and land.
Step 4- To get more height, all you have to do is kick the back of the board harder, and most of all practise!
Hope this helps
