Put your front foot right about the front bolts maybe you are dragging too much Pop the tail harder maybe you are nor popping it enough And pratice , grab a rail and try doing it higher

Pop hard and slide ur foot all the way up to the tip of the board

Tanks I follow you

Pop stronger

Put your front foot farther back to slide more. This will cause you to get more pop

The best way for me to Ollie higher is to keep jumping over stuff like a 2X4 and every time you Ollie over it add another. Also when ollieing higher stuff keep the front foot move towards the middle and for smaller jumps keep the front foot closer to the bolts. And part of the problem is that not the board is popping high enough be instead it's ur fault for not getting ur feet high enough in the air.

Lift your foot to the tip of the nose and pop harder middle air try to bring your knees really high and this will sound stupid but try to imagine there is something you re ollieing over and it may help or may not help but thats my technique

Put your front foot back a bit closer to the back bolts
