I am doing one spin class a week
I won ten free sessions, and Tuesday evening fits in well with a class I have to teach... so I thought I'd just do that... but I can see the value of it as complimentary training - boy, can those ladies in the spin class stand for a long time - and boy, does it motivate me much more than when in my own home

Think I'll be buying a membership when I have used up my ten classes!
