Input:
This resistance band got me through a lot of TurboFire workouts but seems to wear down pretty quickly if used frequently enough. This is the second one I've bought and both have now broken on me in the middle of a workout. Now I'm a fit 6'4 male but certainly not jacked enough to destroy a resistance band. However, when I've decided to up the resistance by stepping out further or shortening the length I could feel it being strained.

It might be because I'm so tall but it after it happened a second time I think it also has to do with the materials being cheap.
