what is RPM

Les Mills International invented 7 category of body exercise, namely, Bodypump, Bodycombat, Bodybalance, Bodyjam, Bodyattack, Bodystep and RPM. I don't have difficulty to understand the former 6 category but what exactly is RPM. RPM is indoor cycling exercise just like the Schwin spinning class we have in California Fitness Center. RPM is the abbreviation of "Raw Power in Motion", a cool name indeed !
