What is the name of a belt that you put on your muscle to keep a muscle from exploding. Or becomeing injured?

Question

For instance, I took a regular belt that I would normally use on my waist and rapped it around my right bicept to keep my arm from over extenuating, or what I call exploding.

It worked and no injuries due to it.

I just need the name of that object, I have seen them in movies where a warrior would be swinging something or lifting something and the arms would be bulging but not exploding.

On FFVII advant children they are used on the arms legs every part that could be strapped, please help out if you know.
