> I get that there can be too much of a good thing etc
Similarly, people that run 45 minutes a day are in great shape. But if you run a half marathon every day, you will age quickly
You’re exactly right, too much of a good thing. And for hard strength training, you can hit that tipping point very quickly. Probably within an hour a day if you’re going hard
For strength you can do a workout within like 25~35min that is taking it slow like browsing socials during pauses.
Talking about programs like rippetoe, 5x5, 531 etc. Unless you have elite genetics or are on juice you don't really need to go beyond those programs.
