weeho, trained today on rubberbands. I've known kipups and nohanded kipups since i was 13 yrs. Managed to do some 2-3 rubberbands

! Gonna practice some more.
just a tip to ppl who're trying this. Don't be afraid. If you do it right it won't hurt. and if you fail, it'll hurt a little, not as much as yuo expect. maybe you'll slam the air of off your lungs sometimes but it's alright.
And when landing, land and soften the landing using your hands, then go on to you upper shoulder. Keep the left / right balance though. I sometimes land on right shoulder only, and that hurts :P ! all the bodywheight on right upper shoulder. *ouch*
peace out.
