I figured out where exactly this new gym is opening in my neighborhood. It's in the shopping center across the street from where I had physical therapy. so it will be stupendously easy to get to. It's even a walkable distance, really, if the weather is decent.
Now all I have to do is pay them a visit to see what they have. I know what the therapist recommended that I should look for in a gym, to maintain the muscle tone I built up via the therapy exercises. If they have that, and if the price is right, I'm joining.
