I have one, haven’t used it a while since it was in storage while I was moving.
I’d recommend doing the power zone classes since they’re very structured so you can track how your improving over time and there’s wide variety of classes based on difficulty and time available (20 min up to 2 hours).
I’ve done in person spin classes before, but I much prefer using the peloton. Probably cause I’m antisocial and whatnot.
