Hooray for physics!

CrossFitters measure intensity as power output. We don’t really care about heart rate, sweating, screaming, or calories burned. We want to know how much work you got done and how long it took. To arrive at work we simply multiply force x distance. How much weight you moved and how far you moved it. If we divide work by time we get power. If you move more weight and all other variables stay the same your power output goes up. If you do the same work and do it in less time your power output goes up. A simple example is the air squat or the push up. The weight you are moving is “you” whether it be hips below parallel or chest to the floor. “You” don’t change all that often so we often consider you a constant. In a workout where you do 300 or so push ups and it takes you 12 or so minutes we can arrive at a power output. At this time of year we have an opportunity for some sweet science. On the 4th Thursday of November we find that “you” change and some of you change quite a bit. This means that if you do the same workout on Thursday morning and Thursday night you will have a chance to manipulate your power equation. “You” unfortunately will not be the same but this means that if you perform a task in the same amount of time in the morning and in the evening you will be generating more power. You will be FITTER by proxy. If you do it faster you will be halfway to the CrossFit games. I am sure you are excited to try this out for yourself. I have the perfect workout for you to test this.
