This video is an illustration of some of the drills I use when training w my Coach, Radner Bearman (who thankfully is still w us), in order 2 develop my core 4 fighting so that it can w/stand punishment & demonstrates just how effective that training is. Since so many men have expressed an interest in gut punching & more than a few are impressed w their abs, I figured why not propose a challenge- let’s see how many men on this site can do what this 69 year old man just did in 15 minutes, just sayin😁💪🏻. After the video is posted, I will write the details of the challenge as shown in the attached video in a blog. Let’s see who has game.
