today's the first class I missed, work got in the way; that happens sometimes. Knot, it's not much like bicycling, the tension is all wrong; on a stationary bike you can build up momentum and the thing spins easier, it's not really like that on a bike. I find it's easier to stand up and pedal than sit down; even though it does raise the heart rate some.
However, from where i am tired and sore; i would say it's going to help my bicycling in the long run! especially since when it gets crummy out i don't want to ride.
