Maybe he could do with an old mattress under the board.

Check out this video:

The first video just shows what some people will do at work when the boss is not looking. Did not think much of his style. Foot straps seemed a bit tight...

Second video was a lot more interesting and showed how to initiate a Vulcan. Guess this is to get you used to the action, but still the old "practice time on the water" can't be beaten.

Personally I'm happy to not fall in (too often) and do a few good carvies. Jumping tends to promote aches & pains.

Looks like my Jman buddy does not like the idea anyway think i might try some of thease ideas in the off season in autumn, when the wind fans shut down.
