Fighting back with the champ rear knee

Showing my boys proper technique on the bag. How to set up and execute the rear knee with punches. Man I look fat lol. Need to get back on a proper diet. Fighting back with the champ. Instructional fighting videos and the “injustice system” we spend the 2 days I’m allowed per month with them working on football, fighting and character building. Gotta use our time wisely. Time is precious
