Just the topic to get me to join this place...
Tri-State Rehab in Ashland is where I've lifted and they're all cool with what I do. Not usually a lot of people to get in your way as it is primarily a physical therapy center. There are a few big guys who come in, some really small with the rest being phys. therapy patients. The rates are pretty good too I believe.
Another bonus is you'll get access to the other centers in the area. There's one in Huntington and Ironton. I haven't been to them though.
Another option is the YMCA. I personally don't prefer it, but if you need more equipment, that's the place to go. Membership is a bit higher though.
