Our resistance and exercise bands are made from the highest quality rubber. The resistance levels are colour-coded, so you can monitor your progression to the next level. Our Safety Toner® resistance bands are designed to perform under the most progressive training styles. A robust safety sleeve protects the tubing core of the exercise band from premature breakdown, wear, and failure in the field while providing an optimal length tension relationship. Safety Toner® by Twist® outlasts regular tubing by up to 5 to 1!
