looks like another interesting way to break your neck
hmhm...as far as I'm informed you are able jog with those jumpers as well
I really don't have a clue about how much energy is absorbed by the mechanics and how much ends in the lower part of your spine - might be good for a nice surprise after a few years...
Ouch...that sounds pretty bad.
if you're a sophisticated skater, snowborder, with good body coordination and some background in athletics... give it a go
the additional height is sufficient to easily break a hand or an arm if you slip without jumping action
errrr.....Nope. I'm not real a sportsman. I thought it could be fun to use it for jogging so I can do something more against my fat belly (because I can't kick myself in the ass in order to jog around the block. So I'm after some alternative to couple that with fun (and avoid pain because of my comminuted fractured right foot.)
Hm I tried inline skating but that was no fun...hmmm perhaps I should go for 80s like roller skates (had a lot of fun the, but I were I child in those times...and it doesn`t take much to have fun when you are a child).
Hm....
