Im 6ft1, 15, with a 38 inch vertical jump. I SHOULD be able to dunk as I can hang on the rim two hand and one handed, but for some reason I can't get the technique right, does anyone know any tips of specific things that I could do to help or that could be going wrong?

If you are a 1 foot jumper you shouldn't have trouble so keep trying. If you are a 2 foot jumper then use your arms to swing you up while you push with your legs.

Start trying to dunk in pick up games get your adrenaline boost and when u go up for the dunk go up on an angle. You should be able to dunk:D :cool:
