I have belonged to Dumbbells for 3 years, and this is the best place to ""work out"" in downtown Denver. This is a place to go for fitness without the meathead/bimbo scene of the bigger more expensive clubs. Very rarely is it too crowded to do your thing, the equipment is great, and classes are timely, professional, small, and always fun. The staff is first rate, friendly and knows me by name and is always willing to accomodate any need I may have. The lockerrooms are clean. As much as I would like to keep this gem a secret, I wanted to make sure it got its proper due. Thanks D2!
