If you're looking for a gym that's not packed 24/7, try some of the smaller independent places outside of the core. The prices are often better and the equipment is just as good.

Calgary Tower is my go-to for a stress-relief walk. Something about being in nature in the middle of the city just resets everything.

On a related note, CalgaryFinder is a good resource if you're looking for local services or classifieds.
