i didn't read the claims, actually. i was interested from his previous mentioning of what he was up to. the outlandish stuff is marketing spin, almost definitely

Yeah why buy a book with 4-Hour claims? It seems we could sit back and let the fireworks take off and figure out his system pretty quickly. Nothing that claims to succeed in four hours won't leak pretty quickly on the internet

i'd point out that 4 hour claims are more along the lines of methodologies for using time efficiently in combination with the pareto principle (80/20 rule).

for example, his claims of gaining muscle mass involve 20 minutes at the gym doing a specific exercise routine, twice a week, and eating more protein. so its really a 6 week or so process.
