Lomachenko has a Sambo background and wrestling background right? And spent a few years practicing dance which helps a lot with leg dexterity and strength.
I honestly found his kicks kinda slappy, hes a little stiff and awkward in the shoulder/back area, he doesnt turn his hips into the kicks and the way he throws his arm back when kicking is awkward (im aware they throw their arm back as they kick in muay thai and kickboxing, I mean the way he does it isnt super fluid).
All in all pretty good, hes super athletic and has years of experience kicking from his youth. Nothing insane though, I mean guys like Eddie Alvarez and Jon Jones were largely self taught into their careers lol.
