Swimming pools have been a popular activity for centuries. They are not only refreshing on hot summer days but also provide great exercise. In recent years, the trend of swim tanks has taken over the traditional swimming pools. A swim tank is a small pool that can be used for exercise, rehabilitation, or relaxation. It is typically much smaller than a traditional pool, accommodating only one or two swimmers at a time. Swim tanks are also known as swim spas, swim current pools, or resistance pools. No matter what you call them, they provide numerous benefits for those looking for an alternative to traditional pools.
