Becoming a Trainer

Hey all,

I want to become a trainer and one day I want to have my own gym but i seriously dont know how and where to start, can someone please help me out. basically I want to know what diploma/degree or program i would do to be a strenght coach or trainer? and can some one tell me what is the significance of bachelors of physiology with exercising? (cause i have done my bachelors already).

And one more thing i am also planning to do my MBA so can i incorporate both of these programs? and any universities in UK or USA which can help me out on this?
