Not done one for a while but I found them very good…
I found it was mostly women at the sessions I attended normally led by some evil 0% body fat gym bunny, best tips I can offer are:
1- take a towel you’ll sweat like a bastard indoors and without headwind and it will drip all over the bars, get in your eyes and annoy the shit out of you.
2- take plenty of water and sip little and often don’t guzzle once every 10 mins as it’ll just sit there and slosh…
3- Set up the bike properly – take the time to set the seat/bar heights and fore/aft position and get as comfy as you can.
4- Warm up/down properly – do some stretches, ideally these will be led by the instructor also spend time spinning without any resistance at the start/finish of the session to help avoid cramp…
5- Try to do everything the instructor tells you to – a good instructor will mix high/low intensity/resistance/cadence sections with sitting and standing stress positions, often set to music (normally crappy dance tracks) – these mean you get more than just a workout for your legs.
6- allow recovery time – I would estimate I’m as knacked after an hours spin as after 2-3 hours on my road bike obviously that’s down to what you put into the session, but it’s worth allowing some recovery time, try not to go 2 days in a row if possible.
7- Go regularly! you will notice the benefit if you keep at it; do two 1 hour spin sessions a week for a month and you will see general fitness benefits, skip a week and you will also notice the drop off in general fitness happens fast…
just enjoy it and remember it is only an hour it might seem a bit tough at first but a session is soon over…
