There’s nothing wrong with a little yelling in the gym every now and then.
Sometimes my wife things I’ve been hurt when I do that. (My gym is in my garage.)
No, if I was hurt, you probably wouldn’t hear anything at all.
We’ve all got a little anger, we all need to release a little fire every now and then.
I mostly train in silence, but, every now and then, it’s good to let the animal inside of you come out, in a safe, controlled place.
