The THERABAND Professional Latex Free Resistance Bands are designed for rehabilitation, functional improvement, and enhanced athletic performance. These bands offer positive and negative force to stretch, tone, and condition major muscles and joints without using natural rubber latex. With the THERABAND color-coded progressive resistance system, users can easily track their progress and the bands come in a range of resistance levels from Super Light (2.4 lbs) to Elite (14.2 lbs). These bands are available in 25 or 50 yard rolls and are 4" wide, making them easy to store and transport for use in any workout or athletic activity.

Elastic resistance force and torque
Elastic resistance is a unique type of resistance training compared to other traditional forms, such as isotonic or isokinetic resistances. The resistance provided by elastic bands or tubing is based on the amount that the band or tubing is stretched. This resistance can be measured in pounds/kilograms of force depending on the percentage the band or tubing is stretched from its resting length; this is known as force-elongation.
Regardless of how long the band or tubing is before it’s stretched, the force produced at its stretched length depends on the percent elongation. For example, an initial 2-foot (60 cm) length of green band that is stretched to 4 feet (120 cm, double its resting length) is at 100% elongation. Therefore, the resistance of the band is 4.6 pounds at that elongation. Each progressive step represents a consistent pull-force increase of 25% in the clinical range (Tan through Black) and 40% in the advanced range (Silver and Gold).
