There is no better home gym and personal workout system that beats the design and innovation of the Rio Grande W-Flow. As an exceptionally equipped swim spa hot tub combo, it doubles as a compact swimming pool for the best backyard exercise available. Equipped with a generous interior of 79 inches wide by 123.6 inches long, you’ll never worry about bumping the walls to get a good workout. Adjust the water flow to perfectly tailor your workouts, easing back while you get in shape and cranking it up when you’re ready for a more challenging routine. Alternatively, you can program your workout to alternate between rugged and lax, to get the benefits of circuit training.
