Programming and tracking my workouts along my journey to a 500lbs deadlift was essential. Jim Wendler's 531 program is one of the most popular in the fitness world and I know from experience that it works. It does require a lot of math and I didn't want to mess around with a calculator all the time. I tried the other spreadsheets available online and none offered the detail and analysis that I knew was possible. So I started my own and spent nearly 2 years developing and making improvements. Now I have the Best 531 Spreadsheet.
