Humans measure things. We know how many years we have lived, how many inches from head to toe, how many pounds we weigh, what grade we got in class, how fast we were driving. Measurement is a key part of human life.
In many human endeavours, besides just a simple static number, measurement is used to to gauge progress toward a goal. To know where we started, how far to get where we’re going and where that end-point actually is, we must measure something.
Of course, measurements can be in non-units. Weight can be measured by how our clothes fit. Fitness can be measured by how we feel at the end of the exercise routine. But there is still some measurement even if it is subjective.
In my latest venture back into swimming, there will be multiple measurements for me to track my progress. How many laps I swam in total (how many total metres), how many consecutive laps of any one stroke I can do without stopping, how many strokes I use in one lap or from the flags to the wall, how many strokes without breathing, how long a rest between sets, how long my entire routine takes, how fast I do a particular distance.
I will of course also have the subjective ones, like how tired I feel after the training, how energized I feel for the rest of the day, how much sleep I need that night, how early I crash at the end of the day, how easy it is for me to get up and go, how much pain my muscles feel afterwards.
Tomorrow morning I will get up and head off to my second day of training. I will be tired and I will be in pain afterwards but hopefully I will have made some progress even if minute. Maybe I will shave one second off my timed swim from last time. Maybe I will swim one more lap than last time. Maybe I will feel less tired afterwards. Maybe none of those will happen.
But I will have made progress just by doing it again.
