Ollie
Why can't I level out my board?Lift Front Foot Vertically With The Board
Mechanism / Why It Happens
Two key requirements for lifting the tail: an upward force on the entire board, and a downward force on the nose
Suppose you are floating in space and the board is moving upward. If you press down on the nose, the board will rotate, and the tail rises as a result. An Ollie works on exactly the same principle: it needs these vertical forces.

What to Do
Accelerate the board's upward momentum with your front foot
At first glance, it may seem that popping the tail is what creates the upward force—but that alone i
Analyze
Make sure that the front foot lifts vertically
The front foot never moves forward until it reaches the peak, and accelerates the board's upward momentum by lifting vertically.
