Ask Kensington: Any good gyms in the area?

Here's another question we couldn't answer (and we're feeling pretty guilty about that).

Emily asks:

I'm looking for a good gym in Kensington - I know of Curves on McDonald Avenue and that's pretty good but what else is there in the area? Suggestions, please!

Please, help a neighbor out. Put down your dumbbells and head to the comments section.
