anytime that we generate a fist in either hand it sets in motion a number of different neural Pathways that allow for a firmer contraction of muscles not just within the fist but elsewhere in the body okay if um you've ever heard the great teachings of Pavo susulan who I hope to have on this podcast as a guest he's talked about how if you were say to try and squeeze a metal bar or think about just trying to give your friend the firmest handshake you possibly can you're having that handshake squeeze competition if you make a fist with your other hand you're actually going to be able to generate a harder contraction of the shaking hand okay of the squeezing hand and this is because of the way that we have these bilaterally U wired uh nerve to muscle connections and the fact that neural activation on one side is related to neural activation on the other side and so forth
