How Did You Go From Being a Member of the Gem to a Personal Trainer?

How did you go from being a member of the gem to earning money off members? One of the trainers at the jim set up an external boot camp. It quickly became apparent that i'm not very good at working outside in the cold conditions. But also, i found it really hard to coach people outside doing sta jumps and burpees when i didn't really train like that. Yet, it works for a lot of people.
