I am good friends with two guys who are business partners and owners of a studio here in the city that I live. One guy run mostly the business and promo side of things and assist with boot camps, ad the other partner does only training and boot camps...he is the "head trainer" while the other guys is the "manager" but they are 50/50 partners. This is a wise way to run it IMO because they both get to focus on their strong points and its one of the reasons they are so successful!
