Exertools manufactures and distributes products to the fitness, therapeutic and rehabilitation markets. We market our products primarily through an extensive network of dealers and catalogs as well as online. Exertools is committed to providing the highest value and best experience to all our customers. Exertools was established in 1990 by Eric Parsells. Located in Northern California, Exertools has been a product innovator for years. After determining that physical therapists did not want to spend time throwing a medicine ball back and forth with a patient, the Plyoback Rebounder was born. The Plyoback has not only become a market leader in the field of plyometric exercise but has also revolutionized the use of medicine balls. Along with the success of the Plyoback, Exertools introduced the DynaDisc in 1993. This exceptional balance disc has become a staple in training & conditioning protocols. It has been featured in magazines like Shape and Men's Fitness as well as several times on THE TODAY SHOW. Exertools now offers hundreds of different products to aid in the development of your strength, balance, and center of gravity (COG) or core stabilization.
