I remember watching Mike Tyson with my dad. We were huge fans. Tyson didn’t defeat opponents–he destroyed them.
If you study Tyson, you see his entire body pivots on his lead left hook, throwing all his weight into it.
Another factor in Tyson’s success is his side hop, which can be seen at 1:55. Lomachenko does something similar, skipping to the side to get a better angle.
At 3:19 we see the compactness of Tyson’s 1-2. It is quick and economical, yet he still gets his hip into the punch. There’s no windup, so the opponent doesn’t see it coming.
Like Marciano, Tyson bounds upward from the crouch, which propels his body weight into his punches.
