I would say that I probably have more experience in the field of health and fitness than anyone on freelancer.com. Over the past 12 years I've been a professional athlete in 2 major sports, a professional strength coach on the collegiate, professional as well as elite high school level. I'm a college educated nutritionist and have had clients ranging from professional athletes, elderly, those with nutritional limitations etc. I have extensive knowledge of human kinetics which leads very well into injury prevention, rehabilitation and performance enhancement.
Beyond the experience listed above, I have knowledge of website development, marketing automation and sales. Being involved with business development and startups in the health and fitness industry as well as few other unrelated fields has given me a vast repertoire of skills.
I would write superb content for your website, i have no doubt that you would be very pleased.
