-Mobile training vs. owning/renting a place
-The hourly rate you charge
-Other overhead expenses (equipment purchase, wear and tear of your vehicle, insurance costs, business expenses, etc.)
-Hours you are willing to work/week
-Individual training vs. group training
-Owning your own business vs. working for someone else
-Selling products other than personal training (supplements, etc.)
