Spinning classes look like really hard work - i haven't been on a bike in years - are they difficult for beginners?

Talk to the teacher - it is a tough workout, but they should be able to accomodate all levels.

I think it's one of the best workouts around - good cardio/interval mix usually.

I love it - it's really easy to do, and a great workout.  Give it a go!

i did find it hard at first, but it feels like a proper workout, like i've really done something.

I guess I'll have to give it a go.  thanks everyone.
