How to perform a back dive with a half twist
Walk to the end of the board, watch the water behind you (this is optional), and turn your back to the water.
Stand on the balls of your feet.
The first times you try this dive, start with your arms straight above your head and close to your ears.

Options: *Make sure your arms have a straight line between them for stability. Bring your arms back to your sides.. *The next time you practice a half twist, put all your weight on your outside foot to lift your arms forward. The second time you try this, don't lose your balance or tap your feet.. *The second time you try this dive, go out to a t-bend, as low as your back will go, and knock off the board, throwing you back to your starting position. This time come back to the bottom.. *Drop your arms to your sides while bending your knees. At the same time, swing your arms back up to your ears and push off the board..
