Rollers

You'll get it, it's really not that hard once you relax and get used to it. Surround yourself with soft things and commit to balancing. Yes you'll fall once or twice but that will help you get used to it.

The control is all through the core, and from an even pedal stroke.

My core strength has lapsed somewhat since I stopped running in organised events. I used to work on it a lot (using one of those big gym ball things). I still think I should be able to master it though. I was just totally unprepared for it not to be easy (had it set-up in a big open space, with nothing to grab/lean-on). Its like yesterday the whole of the internet was saying that it is "useful, straight-forward, training". Then today its saying "does take a bit of mastering though". I might be a bit paraniod though ;)

Anyway I know what I'm doing tonight now.....
