What's it like working as a personal trainer at 24 Hour Fitness?

I am thinking about becoming a trainer at 24 Hour Fitness and just have some questions I want answered that I know won't be able to be answered in an interview. I know how getting paid works, but my questions is, how much do you as a trainer there make on average and how many hours do you put in a week? When you first started as a trainer, what was your average income for the first three months? Also, is there enough to do when first starting to be there 40 hours a week and if yes, what do you do during that time you're not with a client? Thanks for answering my questions.
