Mark Ainsworth

Mark has been very athletic most of his life. However, like so many others life caught up to him, at the age of 45 Mark weighed an incredible 328 pounds at 42% body fat he had been diagnosed with high blood pressure and was full blown Type II Diabetic.

As a result there was an incredible health scare, a doctor told him, "change your life or you will die" and that is exactly what he has done. Over the next few years Mark made an amazing transformation both personally and professionally.

Mark became a personal training director for the largest health club company in the world obtaining multiple personal training and nutritional certifications.

Mark is now an NPC body building competitor and avid cyclist. Today at BodyCentre Fitness Mark spends his time helping others overcome the obstacles he once faced.
