Why would you want to record your exercise routine? Well, because you need to be motivated by your own experiences and because you need to know your numbers. The second reason is applicable if you intend to make exercise a regular habit. You constantly have to challenge yourself by increasing the frequency and difficulty of your routine on a weekly basis. Numbers will guide you through that.
