Korean actor Kim Woo Bin's body trainer praised Kim Woo Bin for his hard effort.
On August 22 episode of MBC's variety show 'Radio Star', trainer Yang Chi-seung made a guest appearance.

During the talk, Yang Chi-seung named Kim Woo Bin as the one who had the most drastic change in his body shape by workout.

He continued, "But he is very tenacious when he starts something. His current body shape was totally acquired by his hard effort."
Meanwhile, Kim Woo Bin is currently taking a break after being diagnosed with nasopharynx cancer in May 2017.
