Henry Hooft, former trainer of former UFC welterweight champion Kamaru Usman, told who gave the Nigerian fighter such a jab.
“We’ve always worked really hard on the jab. But as soon as a person changes halls, everyone immediately begins to praise him and assign all the credit to the new hall. But believe me, we've been polishing this jab for years. You cannot deliver such a jab in 6 weeks or even in six months. These are years of constant work on fundamental things, simple nuances...,” said the specialist.
