It may look easy to some, but the kneeling box jump takes a little bit of practice in order to nail it right. Jon “Bones” Jones has been seen in multiple training videos preparing for his rematch with current champ Daniel “DC” Cormier.
Check out the failed first attempt and see if he lands the jump on the next attempt.
Enjoy the video.
