+1 We've got a Computrainer setup at work with probably seven stations that will hook into it. We ran it with a Sufferfest video that had been tied into the program somehow so when the video changed pace, the resistance units changed accordingly. I liked it a lot better than the spin classes I've attended.

I "conducted" a spin class with some of the guys once, and all I did was repeat what my lone Sufferfest copy does. No "jumps" (whatever nonsense those are), just some intervals and climbing and recoveries. They said they felt tired and well-worked, but unlike with the regular spin instructor, their legs hadn't turned to rubber.
