Artur Beterbiev Heavy Bag Training 

That’s how mayweather hits the bag too. Very interesting.

Yea sometimes, he varies shot power which is something Lomachenko and usyk love to do, very much Soviet style and works great. When hitting even softly he still is able to generate power because he is hitting the bag the right way and maximizing the leverage and physics from he forearms, shoulder, and other joints. He knows how to use his body physics to generate massive power even when throwing at like 20%

Slow is smooth and smooth is fast.

Def masterclass on how to do it
