Training logs after ten years or more of training are a hindrance to good training. How can you train knowing last week you got 8 reps and after decades you are going to get 9 reps? Why not train knowing if you have an off day still hitting the gym is a positive and not a negative. Sure train to do your best but if you get 7 reps it's still a positive. I have decades of training logs. I finally got rid of them and have made better gains. If you are new to training say your first 5 to 10 years. Yes, keep training logs. Compete against what you have done. No one can get stronger every workout or even every year. For many switching to training for muscular endurance will be a new goal rather than strength.
That makes sense, but I don't fully agree. It seems like a false dilemma.
However, that is my fault for focusing unduly on my pre-workout anxiety, chasing strength gains and the like.
On the other hand, while no one can make quantifiable strength gains workout after workout, year in, year out, didn't you keep track of things other than sets and reps? Aches, pains, injuries? General strength/growth *trends* as opposed to looking at individual workouts? Looking back over logs to see if that brief bout of training method X was as good or bad as you remembered? How much better things were when you were getting laid regularly vs. not?

Effect of supplements and other stuff, wink wink?
By the by, while I do love a certain brand of low volume training, I totally agree that something more endurance-oriented is a great way to train. I actually started dabbling with such things before my surgeries/subsequent hernia, like Gironda's 8x8.
But that's neither here nor there
