Kinda agree with some of his stuff. Seems to be more applicable to athletes, not just lifters per say. Most people I find don't do nearly enough volume or frequency to illicit strength or hypertrophy gains they seek. Lotta people seem to be afraid of high volume, intensity, and/or frequency. Most people can (could) push two of those variables at the same time with no negative effects.
While almost all things are relative to a degree, most guys/girls I see irl either practice a lift (besides bench) once a week at most; barely push themselves (squats are a prime example); don't do enough volume; or do a combination of these things.
Granted, not everyone that goes to the gym wants to big/strong/fit/whatever. That's why I all my brehs/brehettes that clearly put in that work.
