I second what Kafer_Girl said - if you are going to do a few invest in a gel seat - v cheap and oh so comfy!

Yep spinning is hard work but honestly you could cheat and breeze through a class. Don't try and keep up with the instructor, leave the resistance at a pretty constant level (except when you're out of your seat but they'll explain that to you) initially.

I wouldn't wear anything too baggy as it can get caught in the wheels - like Dach said 3/4 tights are good - shorts tend to ride up and you'll be fishing them out your bum!

Make sure you have a bottle of water and a towel, when I come out of a spin class I look like I have had a shower - not a good look!

The most important thing is to turn up at least 10 minutes early so the instructor can set up your seat properly, and listen to how they do it so you can do it on your own the next time. My hip flexors are pretty dodgy and if i'm not at exactly the right hight then I can really hurt myself - same with knees.

Enjoy! It is a heck of a hard class but it really, really works. The weight falls off you! Another thing to keep in mind is if you don't enjoy it then go to a different instructors class. I have been to so many and if it's not a Les Mills RPM class then you really don't know what you are going to get. Instructors freestyle spin classes so they choose the music, chorey, everything. I have been to great instructors xlasses that just don't work in a spin class. So if you don't enjoy - DO give another one a go with a different instructor.

Good luck - yay i'm excited for you!!!

What other classes do they have? If they do Combat you HAVE to try it (it's my favourite can't you tell!).
