This, probably could have explained that but unfortunately It was just an automatic thought, you do a set of 50 one day, if you don't get tired or exhausted, add a tiny bit of weight. That's your baseline. That is where you start your regime. You don't do that every day from then on. You know you can do this thing, you make a small improvement each week, or month after that, hell you don't even need to ever do more weight than that. If you can do that, just hit the bar a few times a week, in between some other light workouts, you're already in a better spot than 99% of people.
