Progressive Overload Is King of Muscle Building

There's a way to progressive overload without even adding weight to the bar it's actually by improving the precision of your execution. The two things that go into quality score in my opinion is coordination and control right so can can i coordinate this movement over a range of motion and can i control it at every segmental inch of that range of motion? You'll know because you'll feel it there if you don't you can assume you're not doing it correctly or it could be more effective. What do you think about advanced techniques like negatives like the ARX machine that i trained with at home, are they valuable to just regular people who are just trying to be stronger and build muscle?"
