When it comes to training metrics I like to consider a blend of lifestyle, appearance, and performance related information. Regular physical activity has a myriad of benefits that will impact many facets of your life. There are visual elements like body fat and weight loss, performance outcomes such as improvements in technique and strength, and lifestyle factors including mood and sleep.
Let me explain a few metrics that are worthy of your attention. It is likely that you’ll have a balance that is unique to you and your specific goals. Remember that any metric that you track won’t be worth anything if you don’t make the changes necessary to progress. You’ll be left sitting on a bunch of useless information that you don’t care about.
