Agreed he is training arms but (imo) he's incorporating quite a bit of chest at that hand width.
And yes, I think his stregnth is mild.
I'm first to admit that the kid - well, he's a giant for his age, but his physique is questionable. Nowhere near competition level. He's arms though will be massive in a few years, and everyone's going to know. I do very much admire his dedication at a young age. You don't get that much these days. He will, and I hope he does, have a bright future ahead of him in the BB world.
Correct me if I'm wrong, but Kevin English was never a Mr Olympia. Isn't that title kind of misleading?
Also, if you listen to the video 90% of the focus from Kevin is on "I am, I, I will, I have". It's all "I's". It's more of a promotional video of himself.
But damn, I hope that kid is doing proper post cycle therapy (pct) lol.
