Ok- Looks like nobody is tracking fitness/fatigue?
i went ahead and worked out a system for myself- basically a spread sheet that takes the total of pounds moved from warm-up to work sets and divides that by bodyweight- then multiplied it by an amount that yielded a number that seemed relevant based on perceived exertion.. i assume that the consistency of the calculation is more important than the actual meaning of the number.. so if i stick with this formula at least its constant..
so- here is a shot of my calculator. Its set up for a typical "A" day of Starting Strength for a 175lb person with a Squat work-set of 285lbs and a dead lift set of 315lbs... yields a Training Stress Score of 122

ill stop talking to myself now
