I use rollers instead of a turbo, as you can’t just switch off on them, like you can with a turbo, as you’ll probably fall off if you do! Great for cadence and Z2 long distance stuff, and OK for big gear sprints, not so great if you want to give it full beans standing up (Although better “rollers” than me can use them like that!)
Have something that you can grab fast when you start to use them, like a door frame, or a chair, as they can be like riding on ice for a bit. I found looking straight ahead, rather than down helped…
Edit: That vid!! eeek, I can about grab a water bottle from the frame, and put it back without ending up spread all over the floor and I’ve been using rollers for a couple of years!
