Think this one was about a 5. A couple of modifications i made: When doing the 4 punch combo i would change the 3rd punch so i was doing a jab-cross-*3rd punch*-cross. That 3rd punch could be a hook, uppercut, overhand or elbow. Also when you get to the 4 punch and then fall, you can really pick up the pace on that one and do more than i do in the video. Happy training everybody!
