How's your training going? Are you improving? Getting worse? Do you even know?
With regular benchmarks, or clearly defined and incrementally repeated workouts, you can measure the success or shortcomings of your regimen. CrossFit is a measurable, observable and repeatable fitness program for this very reason. You no longer must guess or assume things about your current fitness level. This means fitness is no longer relative. By keeping workout logs (online or with pen and paper) you can accurately track the progress you're making...or not making. Then, with the help of your awesome coach, make the necessary adjustments for continued improvement.
