There are some posers in my gym who went and bought a few of these. One guy was bragging that he has a red one that only 20 other people I. The country have. Anyways I just laugh at thaw dudes because they are fat and weak and brag about how strong they are while using the band but forget to tell the people that their max is not natural it's with the band. Anyways is there any advantage to using these? Besides thes immediate help from the elastic. To me it's just wack and I'll never use one
