Hey man. If you're a gymnast (X-gymnast, I'd say go for the 90's). If you really want to get optimal height, the 10kg rule only really applies to people who don't know how to jump... there are a surprising number of people who don't.
It's fine for the richer people to say get 80's now then buy 90's a few weeks later. But if you're a little low on money that's not an option.
The 10kg rule is great for beginners. And it's great for people who don't have a lot of power in their legs. But as a gymnast you'll probably find yourself needing a heavier set sooner or later. At least that's the advice I was given by more dynamic bockers... and it makes sense when you think about it.
So the real questions are, do you have a lot of dynamic strength and power?
And, can you afford to buy 80's now, then 90's when you out-grow them?
you know what Brendan, im starting to really like hearing your opinions on things.
although i didnt "do gymnasics" other than when the school were forced to let us via school authority types, i do feel a bit that way out, my bro (drunken) and i can do pretty mad isht off diving boards, we always have been a bit "tapped" but we just taught ourselfs
(ok wait for it, you lot aint had it yet but your about to, im drunk and ranting so HAHAHAHA!!
)
we made a game called F
K ups, the idea was we in turn named a stupid part of your body to bounce really high of the bottom board and then make first contact with the pool using that part of the body, belly and back were old hat by now mind you, so we used the madest things, left ass check, very top of the head, you know silly things that get you hurt.
But although we were rolling all over the place laughing at each others pain the idea of the game was if you intentionally hurt yourself, then when you go to try some bad new dive that you have never tried before whats the worst thats gonna happen?
belly flop?, we do that for warm ups, land on the side of your head? happened, someone got a blister on their ear drum for landing wrong on that one (
happens when you play silly games though huh) see my point?, if youve caused yourself this pain for general jollys, trying new things isnt scary, that just how me and drunken grew up though.
WHICH to get to me to the longest digressed point on pro jump, is why i love your opinions Brendan, i often lack the terminology to put my point across in a clear light, then you come along and do it in 3 lines.
(sorry if this is compllete shizen, i have tried to edit and spellcheck myself, but this how it is at times )
