Are wrestlers like Kenzo Suzuki and others trained martial artists?

Yes, he is and many others are also. He performed in New Japan before coming to America and used a lot of Martial Arts.

Honestly, Kenzo Suzuki isn't. I have spoke to Kenzo before. Yes he has came from Japan but he was just a Wrestler...Not a Martial Arts specialist. Wrestlers like Ultimo Dragon, Tajiri, and Akio are the ones who could be classified as Martial Artist. Kenzo is more of a Heaveyweight to be a Martial Arts specialist. The only thing of the such that he can perform well-ly would be a Super Kick or Buzz-Saw kick.
