Owning a gym is like owning a car dealership, a flower shop, or a candy store...it's all business, and all have similar obsticles. The Kinesiology, Athletic training, Bio, Anatomy would be helpful if you where looking to be a trainer, or interested in Physical Therapy. But that's not what you want to do...you want to be a businessman. You should get into a Business program with a specialization in Entrepreneuralship or small business owner...not all schools offer it, but it is geared towards poeple who want to start their own business. You will need to be able to put together a business proposal and present this to prospective investors. If they dont feel like you know what you're doing, they will shut you down for funding. The sports related stuff is great...but not for owning a gym.
Thats just my opinion.
