I have been training and working out for about four years now. I have worked closely with a trainer who has trained me in the sport of boxing. I have motivated about six people to begin work out regimens and establish healthy eating habits. I love sharing information that I have with others and have now decided to make this a career. I am working towards getting my Wellness and Fitness Coach certification and want to obtain a Personal Trainer Certification this year. How can I generate revenue with new clients without having obtained my certification? Do I need to have one to have paying clients?
