While their standard backyard spas update the '70s hot tub lifestyle for today's customers who are looking for health benefits and relaxation, D-1's Aquatic Fitness system is a next-level take on hydrotherapy. Like other pools designed for swimming, users can swim against the current for endless laps, but they also have a system of bars, ankle cords, resistance bands and other add-ons, all designed to work with water pressure for a complete "underwater gym." Though it felt a little awkward at first, it was easy to get used to, I was surprised by how challenging the workout was and pleased by the lack of harmful impact to the body.
While Dimension One spas are on the pricey side (spas start at $15,000 and Aquatic Fitness models are $25,000 and up), it's the kind of investment worth making if you're serious about hot-tubbing! Contact Dimension One for more info and to find a dealer.
