The Training Effect. The number two coolest thing I learned was the science behind how our bodies actually get stronger. In exercise physiology parlance, the process is called the training effect. It goes something like this. First, we need to overload our bodies. We need to go past our current comfort zones and basically ask our body to work a little harder than it's used to working not too far past the comfort zone where we're likely to injure ourselves. You can think stretch zone, not snap zone. Now, our bodies are remarkably adaptive and don't like getting their butts kicked. And they basically say, hey there, wow. So you want me to be able to lift that weight, run that extra mile, swim that extra lap, huh? Well, alrighty then. Bring it on. And after that little self pep talk, our bodies over compensate, they strengthen themselves so they can handle that new level of stress next time around. Pretty cool, huh? What's really cool is that the training effect applies to every aspect of our lives. If we want to get better at great communication, whether it's in the boardroom or in the bedroom, we've got to go just past our current edge, overloading ourselves with a little more than we're currently comfy with. The same basic thing goes for learning a new language or a musical instrument or meditation practice or basically anything. So how about a little training? And how about a little PS here? Got a drop. A little William James love here. He reminds us, quote, you have enormous untapped power you'll probably never tap because most people never run far enough on their first wind to ever find they have a second pps. Here's to tapping this that enormous power.
