Of course not. I manipulate volume, intensity, rep ranges according to my current goal, wether its hypertrophy or strength. There are workouts where I know I pushed it to the limits, but it is rather an outcome than goal itself. If you push it to the limit every workout then well, after time you will get sore and mildly overtrained and then every workout will have lower intensity. If you keep intensity medium then over time accumulated intensity will be much higher and you will get sorer - mentally and physically - compared to high intensity training. Does it make any sense?
