I know both Tre and Glen, really good guys. If your looking to personal train though you might want to look into other places around Charleston. Lifequest, Aerobics & fitness (West Ashley & Mt.Pleasant), the new Omni, and several smaller gyms downtown might be your best bet. Come to think of it a very large Golds Gym is opening soon on Folly Road, that might be a great launching point right there. Tres gym caters more to hardcore, competition bodybuilders. Its going to take you awile to get noticed as a personal trainer as well, there seem to be tons of them down here. Good Luck!
