If i do spinning by myself on a mountain bike, what speeds and for how long should i do it?

Question

Spinning Classes. Have you taken them. I would like to do spinning on a mountainbike with my best friend, but we dont know what tensions, speeds, or for how long we should do it for.

Answer 1

Spinning is typically very low tension, but very high speed. Your duration depends upon the condition you are in. Although I have heard that for aerobic activity the optimal length of time is 18 minutes. Something about the body tending to burn fat versus muscle and you tend to deplete your muscles after 18 minutes. But 18 minutes is a rather short bike ride.
