It’s not the size of the dog in the fight, it’s the size of the fight in the dog, as the saying goes. That is definitely true – to a point.
In the end, all humans are still made out of bone and flesh, and learning how to use it best can help you overcome physical limitations.
The big guy in the video is Glaube Araújo Feitosa. Feitosa is a Brazilian former kickboxer and a kyokushin full contact karate practitioner who was competing in K-1.
In 2005, Feitosa won K-1 World Grand Prix 2005 in Las Vegas tournament and was a K-1 World Grand Prix 2005 finalist.
While living in Tokyo, Japan he fought and trained in the IKO1 Kyokushin – Team Ichigeki at the Ichigeki Plaza.
Throughout his career he was known as one of the best non-champions to fight in the K-1, a position he earned with his wins over non-champion fighters, such as Ruslan Karaev, Musashi, Gary Goodridge and Junichi Sawayashiki.
How to deal with a much larger opponent –
Size really does matter – but it’s not everything. You may not be bigger than your opponent, but you may be faster, smarter, or more savvy than him. Take advantage wherever you can. Brains are much more important than brute
strength.
It always comes down to who the better fighter is. If someone can teach you how to never get hit and how to hit hard enough to knock anyone out, obviously it doesn’t matter how big you are.
On the other side, there’s only so much you can do to your body.
There comes a point where the size becomes too much. One can say Floyd Mayweather has the best technique, skill, and tactical application of said skill in our current generation of boxers, but it would be a stretch to say he can beat up Wladimir Klitschko.
Although it would seem that increasing muscle mass would enhance one’s martial arts prowess, the truth is that it can seriously inhibit the development of real technique.

Professional athletes know that they should not regularly engage in exercise routines that are not directly related to their particular athletic disciplines. For instance, cross-country runners do not train to develop great upper-body strength and mass; they know that their time is better spent engaging in exercises that will directly affect their ability to run long distances.
The martial arts devotee who focuses heavily on the development of large muscles often has a tendency to overpower his or her techniques due to an over-reliance on excessive muscular force. This results in misalignment of the body, loss of speed, and a subsequent reduction of efficiency.
