+1. Point number 5 is probably the worst part of their post.

Beginners should focus on form, consistency, and linear progression of weight. If you can stand the boredom do the exact same program for a year. Probably 2-3 full body workouts that hit each body part twice.

For intermediate+, hitting a body part once a week is suboptimal for most. People who care about results and progression/growth should be progressing from 5 up to 20 hard sets per muscle per week across the span of a few years. (Compounds hit multiple, so it's not necessarily 20 hard times the number of muscles!) What's "hard"? in the 0-2 RIR range, ideally some to failure. Most people do not know what 0RIR is until they actually go to failure on a weight, compute their 1RM and start to use the computed reps/weight load. For many people "0 RIR" is actually 3+ RIR because they stop themselves short. This is why I mostly only trust studies that take people to true failure (either an inability to move the weight any more, or a coach saying the person significantly broke form and must stop)

For advanced, as i understand it, they need to focus on weekly periodization like hitting 3RIR, 2RIR, 1RIR, 0RIR (test new 1RM), Recovery week kind of cycles. Plus more that advanced coaches can teach.
