We already know the cliché that boxers utilize the legs to generate most of their effectiveness in punching, martial artists use CoD PITT and mix in different moves in a single devastating combo to KO someone within seconds, big muscular thugs with no formal training using their brute strength and size to generate devastating power when they KO a nerd in one hit, etc. But I am wondering. In a case of what-if monkey suppose you aren't a strongman who can pull trucks for miles with a rope and you are in a situation preventing utilizing leg movements and other bodily movement preventing power generation as well as are unable to utilize the whole arsenal of moves such as knees while simultaneously headbutting with a quick follow up by bearhugging ala CoD PITT, etc. Is there a way to generate power just from purely limb based attacks such as throwing the generic "soccer kicks" without pivoting your standing leg and other subtleties while not being in tip top fighting shape? Fantasy scenario example you're a 90 pound nerd who gets tackled and pinned on a couch by a 200 pounder fat guy. He is so on top you the only blow you can throw are sloppy uppercuts on his body and because you're bot lying on the couch you cant utilize your shoulder and legs to generate full power. The space on the couch is so cramped that you can't use your legs for triangle chokes or bit the fatty on the neck, etc use CoD PITT principles. Is there anything you can do to generate enough force to hurt this guy with arm-based uppercuts so he'll get off you? Funny scenario but that couch incident should sum up what I mean by my question. I ask because RBSD discussion and dojo forums brings up so many bizarre scenarios that people are trying to find ways to survive. For example I seen one discussion where people were criticizing boxing because it relies on the legs so much for powers that should you get chained to a chair punches will be useless. Literally one guy said "that's why us boxers train with weights, pushups. and other hard strength exercises so that we still hit hard even if we can only rely on our arms." I was like "wut the hell...." but it made me curious if "limb-based" attacks such as simply bringing up knees without using gravitational force and utilizing your rear leg to spring upward for more power or throwing hooks without twisting your hips along with pivoting legs while lacking the muscles of Conan the Barbarian can still bring enough force to hurt your enemy enough so that you can escape. Is there anyway to generate power with just arms alone in punching, a single leg alone in kicking, headbutting without grabbing the other guy's rear neck towards you, etc in otherwords just using a single limb or body part to attack in singularity without being physically strong? Or is this one of those "Ragnarok" you're fucked up for sure scenarios? The argument about boxing being useless if you're legs are chained to a chair is just one and there are so many bizarre scenarios from five guys pinning you to a wall similar to the American History X rape scene to trying to fight with both arms and one leg in a casket.
