The ExerSwim is a portable device that when placed on the edge of a pool will generate a constant current in the water. This current then allows anyone in the pool to swim for as long as they want getting both a great workout and burning calories at the same time.

The ExerSwim ProTrainer 36 model pictured above is available for a quite reasonable $3,995 on the company’s website. It might seem expensive to some people but when you see those pounds just melt away you’ll know it was worth it.
