Those two things can’t be possible at the same time. Whether you’re sparring or fighting for real, getting punched in the face is the price to pay for being a good boxer.
I remember sparring against somebody who was some regional amateur champion at cruiserweight. I had some weight on him and clearly wasn’t in shape like he was. We definitely hit each other quite a bit but I was the one with swelling and a cut above my right eye after a few rounds.
Sure makes you respect people who do it professionally. It also makes me think that they’re completely insane.
