Hmm...

I always wonder about some of the "high intensity" bike workouts...who teaches the teacher?

How long have you been "Spinning"? It could be a temporary thing till your body gets used to it. But maybe not....

Anyway, I suggest you check with your doctor to be sure there is not something kitty-whompus with your back. Just to be safe

I found out in my late teens that I have Spina Bifida and that explains why I walk like a duck for 2 days after riding a road bike in the road bike posture. Hence I have a mountain bike (a Rainier by Giant)and I'll soon have a comfort/road type bike. (A Sedona again by Giant) Stretching and lower back weight traiing help me immensely.

And for the record, I wouldn't do the spinning type class at the local YMCA. I watched one program of it and I think the Marquis De Sade set up the class guidelines....

The trainer suggested I look into it. I suggested that I not look into it....the recumbent stationary bike is just fine till I can get on the roads and trails.
