Hi. I'm turning 17 soon and I already work at a Gold's gym but I just re-rack weights and keep the locker room clean for 20 or so hours a week. I want to be ready and all set up when I turn 18 to apply to be a trainer. I asked one trainer who works there about it and he said he studied for about 6 months out of some book and took a really tough test. Is that basically all I have to do or is there more? Thank you
