after you've learned how to do it stationary, go out into the streets and learn it
don't be afraid to fall, it's a part of learning skateboarding!
skateboarding is a dangerous and hazardous sport that can result in serious injury or death, i suggest you wear a helmet and pads when learning
Step1
The Foot Positioning
Put your front foot around 2.5 inches away from the bolts, put your back foot in the middle of the tail
Step2
Pop the Tail
Using your back foot, stomp down on the tail of the board, try practicing just popping the tail with no jump first
Step3
Jump With the Board
As you pop up the tail, jump with the skateboard as it begins to go off the ground. (lift your back foot up)
Step4
Level Out
When you're in the air, level out the board by lifting your back foot up. (the board will stick to your feet if you have skateboarding shoes)
