In order to track your progress you need to record your results. There are a plethora of tools available. The tried and true pen and paper can be incredibly effective since you can record it exactly as you like. An advantage to digital tools is their ease of transport and additional capabilities to tie in with other technologies. A digital tool I’ve found to be perfect for my needs due to its flexibility is Workflowy.
Workflowy is an application you can run on both your computer and mobile devices. Its power is much greater than solely workout recording, but in a nutshell it is an effective interface for making lists with advanced search and tagging functionality. Using a program geared specifically for exercise I’ve found to be more restrictive. It has tools built in for choosing exercises and putting together a plan, but you are often limited to the exercises they have already listed. By having no structure you are able to record the data as you like. I’ve found that breaking it into individual days and then exercises on those days to be quite effective. Try it yourself.
