I have been to Rise and HNS. Rise is similar to Destination Dallas, proper bodybuilding culture but has too much Arsenal equipment. HNS is good for powerlifting.
But nothing compares to Absolute Recomp if you're an equipment snob, especially the new Fort Worth location. Everything is Panetta/New Tech/Nautilus/Atlantis. Top tier pieces that hits your muscles not your joints. Apparently, the rumor is the next location they're going to open is around my way. I will join there full time when that time comes.
That's true tho, I haven't really heard about quality gyms in Georgia besides Madhouse. Have you been there?
