Is this way too throw leading uppercuts?

[BCBUD]

I'm just trying to grasp the mechanics of this uppercut is the russian fighter stepping as he throws the uppercut?

Leading uppercut is a very andvanced techqniue, it is physically demanding. Personally, at this moment, I do not fully understand it yet. I suggets mastering basic punches first.

Read JD book, he explains more there. Actually, he did not believe in lead uppercuts at that time. Nowadays, guys like Tyson, Mayweather, Canelo, Ruddock, etc prove he was wrong.

Thanx for upgrade to sugarboxing.com helps me understand better. Yes the russian fighter may not be stepping in just lifting the lead foot.
