It’s actually not that bad. Not as bad as football.
I did it from when I was 12 before UFC was even a thing....
I stopped because when I was 16 I started feeling less and less happy from the punches to the head.
But many gyms now a days are just as rough but physically but understand punches to the head equals weaker jaws and it’s just not a smart way to work.
They realize now, working smarter is better than working harder
