The swim spa, exercise pool and Fitness System comparison can be tricky to understand especially when most of the time they are interchangeable, representing a hybrid of a spa and a pool. They each typically come with a jet or propulsion system designed for swimming against a current, a low-impact workout or both. Swim spas are smaller in size and often include massage jets for a relaxing experience. Sizing, features, and add-ons will vary by model.
