Paul Thorton

Owner / Operator / Certified Personal Trainer Specialist


With a passion for sports and fitness and an absolute love of his chosen discipline, Competitive Natural Bodybuilding, Paul set forth, over 20 years ago, to help others discover that fitness is about so much more than looking awesome in a swimsuit. It’s a lifestyle! It’s safe to say that few trainers have spent more “man hours” helping others strive towards their optimal version of health and wellness. Paul directs and drives home that the tools garnered through one’s fitness journey (e.g, accountability, time management and self- discipline) could have an awesome impact in so many areas outside of a gym setting. This is a driving challenge for Paul, everyday. Lakeside’s slogan say’s it all. Accountability is Everything!
