Get your workout in the water during an Aqua Fitness class at St. Joseph's College in Standish. Those water weights are no joke.
Meadowmere Resort is a fine place for locals to go to relax in the indoor Roman spa and outdoor hot tub, sweat in the heat of the steam room or sauna, or to float around the indoor pool.
Between the indoor saltwater pool, the personal training, the sauna, the rows of cardio and weight machines, and the long list of group fitness classes (including cycling, yoga, thai chi, Barre Fusion, boot camp, and Bodypump), Quest Fitness in Kennebunk pretty much has all the things.
