Step 1: Stretch
Roll you wrists. Stretch your legs and your back. You can also practice on an exercise ball.
Step 2: Practice.
Put your hands in a triangle position. Then lean back, don't be scared. Straighten your arms and lock them in place so you don't fall then just lean back more until your hands are on the floor. If you don't get it the first time keep trying I didn't get down my first time, I fell a lot
