Our History


Island Fitness was built on the cornerstone that exercise is the one true elixir of life and the only scientifically proven method to reverse certain aspects of aging. Just as exercise science is always developing, we are constantly bringing in and developing new programs to motivate our members, keeping them interested and keeping the pathways to success varied and full of choices.

Founded in 2002 by Alexa and Michael Rosenthal, Island Fitness has continued to grow, expanding our facilities, updating our equipment and providing educational support for our employees. We like to say that Island Fitness is your club in the heart of Bainbridge Island. We’re in the heart of Bainbridge Island in the downtown core of Winslow, and in the heart of Bainbridge Island as evidenced by being voted “The Best Place to Work Out” by a reader poll in the Bainbridge Review. The Bainbridge Review interviewed the Rosenthals in conjunction with the club's 10th Anniversary celebration and published this article about our history.
