You should start by deciding how much you have to invest initially and then search out equipment that will allow you to do at least the basic exercises that you want to have clients do. I teach CECs for Fitness Pros, but I am not a serious business person so I don’t teach business exactly. I do include some information on equipment purchasing and selection, along with my experiences with starting and restarting businesses. Anyone wanting to discuss this type of topic is welcome to get in touch with me through my website, www.hawaiifitnessacademy.com . I wouldn’t mind answering a few questions and providing a little moral support.
