Ryan Gosling's martial arts trainer has given the actor top marks for dedication as he trains for a new boxing movie.
 
Muay Thai master Kiu Puk tells Life & Style magazine the star will wow film fans with his physique when he appears in "Only God Forgives" - and he deserves all the accolades and attention her gets for his perfect body, because he has worked hard to get in tip-top shape.
 
Kiu Puk reveals Gosling has been training for two hours a day, four days a week for the past two months - and he always comes prepared.
 
He says, "Ryan's disciplined and enthusiastic, and above all, he loves his training. He trains for around two hours at a time - it's pretty non-stop."
 
And Puk admits the actor is one of the easiest stars he has ever trained - because he does what he's told.
 
The trainer adds, "He's polite, always listens to what I'm saying and follows all instructions... I've recommended that he stick to a traditional Thai diet of fish, green vegetables and rice. I can tell he's sticking to it."
