An ollie is one of the most basic moves. it is when you jump up in the air and get all four wheels in the air.
Step 1: Position
Front foot inbetween the two sets of nails. Back foot on the tail.
Step 2: Lean and Jump
put your weight on your back foot. Jump up while pushing down on your back foot. Your front truck should go up first. (Like in the picture below)
Step 3: Slide
Slide your front foot across the board. this will straighten your board so it's level. (optional)
Step 4: Landing
The landing is easy just move your foot back to the board from where you slid it. Don't bother working on your position you can get that back to normal position on land.
