I highlight the "or more" part because it really emphasises the slant of his comment - Jordan is talking about people who want "optimal". Optimal is not a realistic goal for the average person with a full family, etc. If you want "optimal" and you are single with 1 job and no kids, fuck yeah, lift as often as necessary, do 2-a-days, etc. Competitive athletes have to do that, because they have to seek "optimal".
To Chebass's point, not-optimal =/= bad. Any setup that isn't totally retarded but is stuck with consistently and has the basic principles of overload and specificity managed will lead to positive results and progress. So what if you only put 80lbs on your lift this year instead of 110. Or 30 instead of 40. Most people are happy enough to just continue to see progress. If you're a competitive athlete in the barbell sports, you need to seek optimal. That's not most people.
