i think they do... infact ROM is always brought up when discussing strength... not just how muc you can lift, but how much over what distance, right?
like i said impressive, but not a good way to mes. strength... this is a guy who claims a 300lb behind the neck shoulder press,... then he posts this pic...
what about palming a basketball? if someones fingers are super long to help them grip it, does that mean theyre stronger?
Demonstrable strength, one's ability to lift a given load is determined by many factors some of which include bone length and insertion points of the muscles. Neurological efficiency is yet another factor and some people just have "better" nervous systems with respect to the recruitment of motor units than others. Should we say, "Ahhhh, he isn't impressive he just has a more efficient nervous system."?
Humans cannot compete on an even ground with respect to the factors you are trying to invoke with your shitty argument. About the only evening of the playing field that is accepted in strength competition is a weight class.
