Let me start off with the disclaimer that I’m pretty sure I squeaked by with a C in physics. I’m really truly hoping that someone far more intelligent then myself will read this and be inspired to put something more comprehensible and useful together for the good of the exercise industry. Most likely this has already has happened, clue me in, I would love to read it. For now here’s a peak into the sloppy place called my brain.
I have heard over and over, “Our bodies are a system of levers and pulleys”. Although I agree with this, it’s not in the sense of a simple rope. These levers and pulleys are pulling on our internal springs. When this “internal spring” term is used it is most commonly used in the context of the legs, more specially the vertical jump. However, I see springs everywhere in the body.
Ok let’s start simply; there’s two ways a single spring can generate force while trying to return to its original shape. If you push inward on a spring and let go it springs outward. If you stretch the spring and let go it springs inward. What I think is really of cool is that the potential for these two forces are rarely equal in the same spring. A tight spring is going to generate more force stretched then compressed, and a stretch out spring is going to generate more force compressed.
Ok so how does this relate to our bodies? Lets look at two bodies like these two springs. The tight spring being compressed is an overly stable body. This person’s workout has consisted for too long of adding load and resistance. At some point they did get bigger and stronger doing this and common sense dictated more is better. There most likely exists the potential to load lift or pull more, however something very different has to happen first. We need to take some of those strings and lengthen them and pull a couple turns out of the coil. This is going to feel much harder then the exercises they are used to not only because they have to expand (circumference of spring), but they are working on mobility (lengthening of spring). Once this happens the springs become stronger and they are able to handle those loads with out completely compressing their potential for energy.
The stretched spring is someone hyper mobile but unstable. This person’s workout has consisted of expanding and lengthening for too long. They need to twist and tighten up their spring not only for that rebounding energy but also for stability. If you took a really stretched out spring and compressed it, it most likely would flop to one side or the other not go straight down. You have to give it a little twist on the way down tightening it up to the center it would compress in a more balanced way.
We’re not just one spring though, the levers and pulleys control that balance of the springs and the relationship they have to each other. Hook some springs together and what do you have? An overstretched one can’t effectively pull a tight one. A tight one doesn’t give an overstretched one a fighting chance of compressing. Add in the internal and external rotation there’s all kind of interesting things going on. This is where people are failing at stretching and stabilizing. As I have said before look to the opposing structure of your problem and you will find your path to healing and strengthening. Think of how you can get expand areas of your body that feel very rigid, and how you can bring stability to areas that are very flexible. The balancing act will surprise you and teach you wonderful things about your structure and potential.
