Anyone done this? If so, can you recommend a class? I'm in MoCo, but would consider traveling for a good class. Is it all older people doing it or is it something the 20-somethings are doing? I'm really out of shape (50 years old) and thinking about trying it. I used to do spinning and loved it, but it has been years. Need to get back in the saddle and do something regularly.

Pluses, minuses, lemme hear it.
