Lol at making money working for 24hr. The only way to make money that I've seen being a trainer is working for yourself and not having to give up 30-35% of what you make to a gym. Some gyms pay their trainers an hourly rate and charge up the ass to the clients. I'm not a trainer so I may be wrong in the percentage you give them. At the end of the day I know the trainers there don't make a whole lot of money.
I train in my spare time at my local gym, and have to pay them almost 150 bucks a month. They're already making money off of me bringing new clients in and making them long term customers, so it kinda sucks to have to pay them even more...
