Soreness is not a reliable indicator of a good workout. You don’t have to feel sore. It is satisfying af though.

I think everyone is different. Jay Vincent never said that more volume doesn’t create results but I think for some people, less volume will give them better gains. For me, my arms looked more pumped and grew more after I dropped bicep curls and tricep extensions. My back and chest exercises were intense enough to stimulate growth there. The fact that my arms grew after I stopped doing those two exercises says a lot about how much stimulus my body needs. I was overtraining. Op said that no matter how much additional exercise he does, he can’t make any growth. Which makes sense because your muscles have a limit to how much force it can generate. You can do a full speed sprint for only a few seconds or you can do a low intensely slow jog for an hour. Both are forms of exercise that stimulate the same muscles but sprinters and have much more jacked bodies compared to marathon runners. Intensity vs volume. In other words you can train very intensely for a short period of time or you can train for a long period of time at low intensity. As intensity increases, volume must decrease. The problem is that fast twitch muscle fibers are difficult to sufficiently fatigue without going really fucking heavy and risking injury. Or you can train at a moderate weight to failure and reduce risk of injury substantially.

Mike Mentzer trained a lot of normies on high intensity sets to failure and he noticed that when he’d give them more rest, they’d come back stronger.

Here is a good example of the difference in force generated when going slow and controlled to failure compared to fast reps.

Also you can always do a warmup set before you go to failure. I also like to do drop sets to failure if I feel like I didn’t push to my limits.
