Have been to a few on the list.
There are quite a few gyms across the country that I would consider "getting down to business" type gyms.
There are also gyms across the country, which are a bit different. I put on my Iron Chamber shirts, and I think about hard work, no frills and getting it done.
Before my The Pit shirt wore out, I would put it on and think about the sweat and effort that has and continues to go through there, as well as the knowledge that has come from there.
Many other gyms across the country like those.
Here's some information on some other gyms around the country:

Have been to a few of these as well, and there is work going on at 'em.
