Numbers don’t lie, people.
Keeping statistics of your numbers, regularly reviewing them and adjusting both your workouts and goals have proved to have the biggest impact on my trainings.
There were times when I just trained haphazardly. Not exactly only when I felt like it, but close..
While it is not exactly a tactics I would recommend, I went too much time doing this. And the results (or lack of something to be proud of) were obvious.
