The Korean Zombie hasn’t fought since his UFC 163 loss to Jose Aldo back in 2013. Following that he suffered several injuries that kept him on the sidelines. He then was forced to sit on the sidelines for two years while serving a mandatory 2 year term with the South Korean military.
Fortunately The Korean Zombie is still able to train despite his service in the military. Check out this footage of him using fencing to train movement.
According to Google translate the caption reads:
“Fencing 2 for parking … martial arts, fencing began to win McGregor. Nationals middle of next year goal”
