My coach charged me $70 for a session & he worked & talked with me for well over 2 hours - BUT, he's a fitness nut like I am & does it more for the love of it than the money - he has a f/t job totally unrelated to fitness.
Additionally, he wants to promote the sport of olympic lifting & that is more important to him that making money. So I think that fee is somewhat cheap for his caliber.
I don't pay anything now that I'm a team member - I train with him & other team members (not that many people) & he's setting up a program & helping my form - watching me as we're working, but I'm not paying anything. Since the team itself is a non-profit organization, he can't charge the members for working out at his center, even though I think he owns the center himself (or pays rent on the property out of his own pocket). Non-team members who want to come train there (like my current training partner) pay $5 per workout - & he still helps them out. What a guy!
I received my certification through the ISSA. If you go to their website, you can search for one of their personal trainers that's in your area. www.fitnesseducation.com is their website. Hope that helps...
