why would you practice the stuff on the ground first? that seems backwards considering the ground is hard and unforgiving when the water is completely the opposite. its also a lot more about timing when doing long falls like that instead of jumping off a diving board and having at it. i did a little diving when i was on the swim team in high school. i wasnt exceptionally good at it, but i got the job done.
i like the video though, it started out a little slow.
