Logan Paul's hardcore training for WrestleMania 38 is going off without a hitch ... so says WWE Superstar The Miz, who tells TMZ Sports the YouTube sensation is an "absolute natural" in the squared circle.
As we previously reported, the "Maverick" made a surprise appearance at Raw last week ... officially confirming his spot as Miz's tag team partner against Reyand Dominik Mysterio in April.
We spoke with The Miz about the preparations leading up to the big event ... and he says he was floored by how quickly Logan got comfortable with the complicated moves.
"Training's going really well, actually," he tells us ... saying Paul was even able to nail his signature Skull Crushing Finale in no time.
"Logan -- I showed it to him like, once. Literally picked it up like that. I was like, 'Oh, okay. This is gonna be fun!!'"
Miz says Logan's amateur wrestling background (he was a beast in high school) and boxing training has helped him immensely ... and it's going to show in his performance.
As for Paul's future in WWE, Miz says he truly thinks Logan could go full-time with Vince McMahon's organization.
"If he does well at WrestleMania, this could lead to something more."
