>>76287254 (OP) When you hold a bar for a pushing movement, it naturally rests in the fleshy part of your palm and right between your thumb and index finger. If you try to do that for pulls, you're a retard who is going to have a bad time.
That texture is there so you can grip it and it doesnt slide around in your palms. If you dont grip it then it will slide around and give you blisters. You also probably have soft skin faggot.
