It's really variable depending on your business model and marketing. If you're working for a chain like Fitness First then I would try to fill up with 30+ hours of training, as that's how you make your money.

If you're running your own business then you need to make sure you have time to work on your business as opposed to just training. It's important to do that with a place like Fitness First as well, but chances are they have mechanisms in place to at least help you get prospects. With your own business you do it all.

Remember that chances are you won't work a normal schedule as well, especially starting out. If you manage to line up clients in a nice, even 4-8 hour stretch, then you're doing great. It's more likely to be one client here, two here, etc.

I found that when I was just training clients I might "work" a six hour day but I'd be at or around the gym twelve. You'll have a lot of unpaid time.
