I have always been abit confused about the "logic" that claims small people get kicked less than big folks.
If that were true it wouldn't it be safe to assume that smaller guys would win the heavy weight weight boxing division ?
I'm not a big man and I've learned to shoot heavy recoiling rifles from the bench by locking my upper body onto the rifle and allowing my body to shift the energy by letting my waist flex backwards and not trying to stop it.
If you watch the video posted above on shooting the .460, you can see this technique used quite well by a couple of the skinny guys.
And no, I am not going into the ring with even a middle-weight boxer again. Once around with the ND/SD Golden Gloves Champ was enough for me.
