For the business purchaser who just wants to help folks tone up, slim down and bulk out, there are a number of  franchises you can do that and make money from it. 

How easy will it be for the public to visit your gym? Choose a location that suits you as an owner to attract customers. Try to find a location as close as popular to a popular location in town. The best time to get on any rising trend is on the ground floor. Do the necessary research.  Franchises are a great way to be an entrepreneur and have a higher success rate than those who start their own business from scratch.

Fitness franchises can be expensive, restrictive, and occasionally difficult to buy. There's a lot of equipment involved and usually a good deal floor space required.

Just buying a big name might not be suitable for you. If  you know nothing about fitness or have no desire to make fitness part of your life, what makes you think you could be successful with a fitness franchise? The brand name will only carry you so far. You may invest time and cash into something and have nothing to show for it, except debt. Try not to let your emotions run away from you. Just because you like something as a hobby doesn't mean you're suited to make money from it. 

Worse still, making a business out of something you love could ruin your enjoyment of it. To paraphrase Shakespeare: "To sport may become as tedious as to work". Choose dispassionately.

Choose a franchise that is a match for your interests and abilities and that also has made a good reputation and brand recognition for itself. It need not be the biggest name. Think about your alternatives and chose the franchise that suits you best. 

Have meetings and discussions with your franchisor and find out how they have managed to stay ahead in this competitive industry. Run scripts, ads and marketing pieces that will sell your gym’s value to more and more people.
