So an interesting thing that many don't know about me is, before I got into the field of kinesiology, I was actually a music major. Yep, a music major. For 3 years, I was a double bassist for the Iowa State University symphony. I had been playing music for a little over 10 years. Played all through high school for a matter of face. Anyway, during that time, I learned a lot about music. Aural theory (the ability to figure music out by listening to it), written theory (the ability to look at music and figure it out in terms of its actual structure), piano (considered the be the universal instrument), private lessons, and obviously symphony.
It was about a year into my music education, I discovered kinesiology. In the fall of 2009, I switched 100% to kinesiology and never looked back. It's odd how life works. The more I continued to learn about exercise science, primarily strength and conditioning, the more parallels I found between the two fields. Even today, I continue to find parallels between the fields of study. The one parallel that I find the most fascinating is the idea of rest.
During one of my aural theory classes, that's where I learned how to "decode" music by listening to it; Dr. Jeffery Prator once said, "A rest is just as important as any note." For some reason, even to this day, that quote has stuck with me. Then during one of my written theory classes, we began to learn how to construct music itself. It wasn't until I started creating my first training cards, 2 years later, did I see the first of many, many parallels between the 2 fields. Speaking from personal experience, a training program/card is no different than a piece of sheet music. If you're not experienced with either one, at first glance, a training card or sheet music appears like it needs a key to decipher what's written on it. However, to an experienced eye, either one is easily read.
Now you're probably wondering, this is all nice and good, but what does this have to do with anything? In the words of Yoda, "Everything!" because if there is one parallel, there have to be others. And you're right! I started, as Steve Jobs once said, to connect the dots between these two fields. Over more time, and astonishingly enough, I began to find more and more. I remember one day thinking, "Holy crap, this is just like this from my music theory class or my piano class." There are many specific ways the two relate to one another, that I could go into a few others, but I'll skip them and get to my point. The most important parallel between the two fields is, just like resting (silence) is written into a symphony, coaches program rest days (recovery). This brings me to the point of this all and the title of this essay, the rest days are just as important as the training days. Now here's the reason why.
The human body is the most fantastic machine in the world. Yes, I said it, machine. If you break it down to its most basic components, the human body is a bunch of interconnected levers. Now here's the other thing, just like a machine, the human body will break down if it runs too hard for too long. Regardless of the physical activity, the stress incurred by the body will eventually break it down. The fantastic thing about the body and how it differs from any other machine in the world is that it will adapt to the stressor placed upon it (Hans Selye's General Adaptation Theory). However, there is an important fact to remember to all of this. The body can only take so much stress before it starts to deteriorate. And this is where rest comes in. During the scheduled rest periods during training, the body is allowed to recover and, most importantly, rebuild (muscle) and reregulate (hormones) itself. Yes, you read that right. It is not the training sessions that make us stronger. It's actually the scheduled rest periods we take that make us stronger.
But why don't we think about rest days with the same importance as the actual training days? To be completely transparent about this, this is my professional belief, American society has been ruined by companies like Gatorade and Nike. American society has been inundated with the idea of "1-more" when it comes to sports practice. 1 more jump shot, 1 more swing of the bat, 1 more throw of the football, 1 more practice spike of the ball. So on and so forth. The same idea can be said about training, but this time, it primarily comes in the concept of 1 more rep or 1 more exercise, 1 more day. Where does rest fit into their equation? That's the thing, it doesn't.
As a coach, I have heard many different reasons for pushing so hard. And the one line that I hear some form or fashion of the most is, "If I don't train today, I'll lose it." Yes, this is true, to an extent. However, in this case, the magnitude as to how fast the body will lose said adaptations is a little off. It takes the body a reasonable amount of time to lose the gains it has achieved (7-20 days, depending on specific adaptation). I could get into the exact science, but I'll save you the lesson and just ask that you take my word for it. So here we are, pushing and pushing and pushing to the point of exhaustion, and more than likely not gaining a single thing out of it.
Now there are 2 scenarios that I see playing out in the end. One is incredibly likely, the other takes a lot of luck not to occur, and that is injury. I can say with almost certainty that an injury will occur if a rest period is not taken. Now to stay fair in this discussion, I'm not saying an injury will occur. All I am stating is, with every passing day, week, or month that goes by without a scheduled rest period, the likelihood of injury occurring increases. Just to clarify, when I state "injury," I'm not talking about a torn ACL or broken leg, which can happen. When I say injury, I am primarily speaking of pulled muscled, strained ligaments/tendons, the little things that, if not addressed, can really hinder adaptation and gains.
There is also the other side of the coin. Even after five months of exercising hard, and injury never occurs. All I can say to that is congratulations, you rolled the dice, and it didn't come up snake-eyes.
Let's face it injuries aren't any fun. So if you don't like injuries, allow the body to rest. Take a day, a week, or even a month (in some cases, a month of rest is needed) follow the rest day like you would any training day. Allow the silence to occur and bask in it for a while. Here's a thought, give even more effort during the rest day than you would a training day.
As I mentioned earlier, every beat, every note, and moment of silence, in the greatest of symphonies, was planned and put there for a specific reason. The same is said for training. Every exercise, set, rep, and rest day has been strategically designed to help ensure the greatest adaptations possible. So next time you have a rest day take it seriously and sit back and enjoy the time off. Why not listen to a symphony. Personally, I recommend New World Symphony or the Planets... they are my favorites. Anyway, I hope you enjoyed reading this.
