Movement has 3 large gyms in Englewood, Golden and Baker/5th Ave, all with fitness areas. There's also a bouldering gym in RiNo with a fitness area. movementgyms.com/
I would recommend Movement. You get a gym at Englewood(Formally Earth Treks and it was the largest climbing gym in the country when it opened), Rino(bouldering only), Golden(small and stiff), Baker(small), and Boulder.
