Anyone use one of these? It is called something like "C476" and the lights are bars showing floors per minute going left to right. It is one of the ones where you are trying to keep your body up taking explosive steps, when you increase the workrate the steps fall faster and you have to hit them harder. You can cheat by holding yourself up on "A" shape arms and flipping your legs beneath you pointlessly. Anyway, I'm the only person in the gym who uses it, so does anyone else use one and what can you do So, without cheating, ie hands forward and weight back, at lunchtime I set a new PB - 270 floors in 30 minutes, 3 minutes at 10 floors a minute, 3 at 8, five times through. So nine a minute average, but a bit harder because done as intervals. I reckon I might be able to do 280 if there was money on it. [If anyone can do, like, 350, don't tell me - I'm not sure I'd recover from that kind of crushing blow].
