[Insanity]

To be charitable to both the article and the OP - his advice of “hard work over time” is still good advice.

I think many people tend to get stuck in premature optimization, which can take the fun away and thus you end up quitting. I did that a few times, so it might be a me-thing.

Nowadays I exercise 4x/week without really worrying about a strategy or about optimal protein intake etc.

But then again, nowadays my goal is just to live healthy rather than gain strength.

Going further, you don't even need to count your reps or track how much weight you're lifting. Literally just do any exercise with any weight per muscle group to near failure for 2-5 sets. Rest the muscle groups you targeted the next 1-3 days, and be consistent every week. Bodyweight, free weights, machines, bands, kettlebells, etc. are all fine. That gets you 80-90% of the benefit with no stress.
