The amount of contradictory advice slung online in regards to fitness is immense. (Same as it ever was, the old muscle magazines were bad, too.) Lots and lots of “evidence” amalgamated from rumors, second-hand sources, that old guy at the gym, and teeny tiny studies that have never been replicated.
As you go on a fitness journey (it hurt to type that), you go through decision paralysis, overbearing overconfidence that you know what’s up, and you end up with humility that boils down to “iron ain’t gonna move itself”.
