Great Bay Athletic Club has been serving the active lifestyle needs of Newmarket for more than 37 years. Under the current ownership since 1999 the club has evolved from a racquet sports facility to one of the largest comprehensive active lifestyle centers in New England. With 55,000 square feet of climate controlled indoor space Great Bay provides something for everyone – we are truly – judgement free – welcoming weekend warriors to “lunks”. The latest fitness trends and equipment are provided to members with the space to enjoy them. Our latest additions are The Tank and a React Trainer.
