I heard someone quoting a study, it basically said that you only need roughly 1/3 the volume/sets/ effective reps however you want to categorize it, to maintain muscle you had built. So if you needed 20 hard sets to gain muscle then 6-7 weekly sets would maintain that. Do you find this to be true?
As far as genetic potential goes, I think you gotta shoot for more than you’ll ever get unless you’re just happy with you’re physique. I know that after 5-6 years things slow down drastically if you’re natty. From experience. First few years I could just push a little harder and see gains now after 8 years of pushing hard and giving real effort I don’t see much improvement after a year. The Greg duecette video I posted is great. I’d recommend checking it out.
