A couple days ago I was talking to a fellow crossfitter, struggling to explain my daily routine to someone who works a typical 9-5 office schedule.
I haven't published anything to my blog for a few weeks now. I have been writing (mostly free form) but there has been too much new material in my head that hasn't yet coalesced into anything coherent...too many free floating loose ends. For the past week or two I have been intentionally taking long lunch breaks so as to avoid reaching that point of frustration that tends to sneak up rapidly when I am just getting back into a productivity groove. This is what I was trying to clumsily explain when I realized that crossfit (and physical exercise in general) offered a more accessible angle. One thing you quickly learn in crossfit is to never burn out early in a workout...to never go all the way to the point of failure. Let's say I'm doing a workout that involves five rounds of:Run 400m20 push ups
15 pull upsPush ups are a big weakness for me. If I try to do sets of 20 unbroken I will probably get through the first round without a problem but then reach failure somewhere in the second. Once I reach that failure point I will be burnt out the rest of the way, probably unable to squeeze out more than two or three push-ups at a time for the remainder of the workout. If instead I come back from that second run and do a set of ten, shake out my arms for a couple seconds, do a set of five, shake it out, another set of five...I will be able to maintain that pace through all five rounds. There is a body awareness that develops after a while, being able to gauge when you are approaching your failure threshold and stopping just short of that point, beyond which your body will begin to shut down.That is a near perfect analogy to the management of tempo during challenging cognitive tasks. A reasonable amount of straining builds long term capacity. Too much straining and I cross that failure threshold...frustration sets in, my brain shuts down and short breaks no longer provide a meaningful refresh/recharge. *Beyond this specific analogy, I am intrigued by how frequently I am finding analogies between physical and mental performance. At least for me, physical performance is more transparent/accessible than mental performance and therefore provides a useful lens for studying struggles with procrastination, motivation, energy levels, etc.Conversely, the analogies almost surely all originate in the brain. People often talk about the brain as a muscle but it would be more accurate to talk about the muscles as an extension of the brain. The physiological phenomena described above have less to do with muscle failure per se and more to do with automatic processes in the brain acting as safeguards against self inflicted injury.
