Not an athlete
I bought an individual Zippy rock along with the Flow board so I could start off with a beginner-friendly set-up, and I've been using it for about a week now. My first time on the board was terrifying. I didn't fall, but I was heavily relying on a couple high backed chairs (holding the backs, at chest height) to remain stable. Still, just the little bit of movement and balance I managed was fun.
Since then I've been playing around on the Flow board/Zippy rock for a few minutes each day, and I'm amazed at how quickly a non-athletic beginner can pick this up. I don't need to have anything nearby to help me balance anymore. I'm still mostly just going side to side, but I find myself using more front-to-back motion. I can make turns pretty easily. I can watch TV while doing an easy side-to-side (and some minor turns to readjust) on the Flow/Zippy and actually follow the plot. It's just coming naturally now and no longer requires 100% of my concentration.
If you're a complete beginner and not sure where to start, I highly recommend the Pickle Nub board and this Zippy rock with either the Flow or its own Zippy board. Don't worry that you won't be able to use them - just about anyone can learn to use these. Take it as slow as you need to - the improvements come quickly!
