A swim spa allows you to enjoy the health benefits of swimming without requiring space for a full-sized lap pool in your backyard. Instead of swimming a longer distance, you swim against a current in the water, which is completely adjustable based on your own fitness level and needs. Like a regular spa, these units are completely self-contained and free standing, making them much easier to install and maintain. They can also be used indoors or out, so you can continue training even through the winter months if you have an indoor place to install the swim spa.
