Resistance bands are versatile and effective tools for strength training, rehabilitation, and flexibility exercises.
In the past, These bands come in different colors that indicate different resistance levels, allowing individuals to personalize their exercise routines according to their fitness goals and abilities. The colors of resistance bands vary across brands, but generally, they follow a similar sequence of color-coded resistance levels.
Thera-Band and Cando were the first to creat color and stretch grading systems for their own products.
| Color | Resistance | Muscle Group |
| Yellow | Thin/Easy/X-Light | Shoulders and shins |
| Red | Light | Biceps and triceps |
| Green | Medium | Legs, Chest & Back |
| Blue | Heavy | Legs, Chest & Back* |
| Black | X-Heavy | Legs, Chest & Back* |
| Color | Resistance |
| Tan | XX-Light |
| Yellow | X-Light |
| Red | Light |
| Green | Medium |
| Blue | Heavy |
| Black | X-Heavy |
| Silver | XX-Heavy |
| Gold | XXX-Heavy |
But as the resistance bands became more popular, more and more plants began to embrace customization, where specifications and colors could be specified and customized. So the relatedness between color and elastic grade was faded.
You can create your own color and grade system according to your company’s requirements, such as pink series, gray series, blue series, etc. Each series set has its own grade description.
