The basic answer is that you can swim in a swim spa regardless of your level of competence. This flow of water presses on your body while you swim, keeping you in a fixed posture akin to swimming laps in a swimming pool or lap pool. The type of swim spa you select will determine how much control you have over the exercise. With a regular spa, there's not much you can do from a safety standpoint to vary the workout. But with a hydrospa, you can adjust how deep you go by changing the height of water you're floating in. You can also vary the resistance of the water by adding balls or towels to it. Swimming is a great way to get in shape and have fun at the same time. It can be done anywhere — in lakes, rivers, or even in the ocean. The only requirement is that you need to be able to swim 25 yards without stopping. If you can do this, you can start learning how to swim. If you're new to swimming, start out by simply moving through the water in smooth strokes. As you gain confidence, add some kicks. There are many different types of strokes used by swimmers for various reasons. But one thing that all swimmers share is the ability to move their bodies back and forth like a boat through water. You don't need any special equipment to swim.
