I have absolutely no idea what the previous poster can mean by RallySport being a meat market, it is a very professional and serious gym with a minimum of poser factor. The equipment and the instructors are first class all the way, and the members dedicated and focused atheletes.
There are 3 floors of class and equipment rooms, plus 2 pools and raquetball courts. Massage and other therapies are offerred. Classes include many yoga classes, various types of aerobics and martial art based cardio classes, power lifting, and fantastic NIA dance daily.
I travel all around the country and have not found a more inclusive and professional club than Boulder Rallysport.
Pros: Best staff and class schedule, convenient location
Cons: day passes not available
Not a bad gym, but its a meat market. Also expensive. If you want to shell out the money to try to meet someone, I guess it doesn't matter if its a bar or a gym. However, if you're serious about working out without a lot of distractions, it may not be the place to go.
Pros: Big gym with good equipment
Cons: Meat market and expensive
