Comment on Optimal Exercise

Hm. Some thoughts, since I don't know if it is that simple...

I shared your sentiment (about personal trainers possessing about 1500 words of total knowledge) until I injured myself several months ago (cervical discs). I lifted weights fairly consistently for more than a decade with high intensity, using principles related to the ones you describe. I'm confident there are other factors—genetics, poor posture, non-optimal sleep position—that helped cause my injury (which led to an immediate 65-75% loss of pushing strength and dramatic atrophy on my right side), but I suspect my consistent vigorous weight training was a key culprit.

Generally, you're failing (in my view) to point out a physical trainer's role and value in teaching correct technique, which can alleviate risk of injury. You mention form a few times, but I think it is fair to say there is a significant difference between watching a Youtube video and having someone (who is trained) demonstrate the proper form in person, providing feedback and adjustment based on their observation.

Free weights are generally better than machine exercises

What does this mean? Newer machines are designed to limit risk of injury—promoting proper form and safe range of motion through their design—and I see very little basis to say free weights are "better". (It's a common adage in strength training circles, and I'm aware of the advantages of free weights vs. machines, but machine exercises are just fine—if not "better"—for basic strength training.)

•Optimal for looks •Optimal for time •Optimal for effort •Optimal for performance •Optimal for longevity

I like the distinctions you've made here, though I think the advice that follows comes nowhere close to encompassing the knowledge of good personal trainers.

Using your advice, you could optimize for the first four, but longevity would be a huge question mark (if by 'longevity', you mean consistent health and wellness as a result of your exercise routine).

I used to scoff at the idea of personal trainers. From what I could see, they were overpaid, personal cheerleaders who rattled off common sens-isms. Now, I've got an appointment for a cortisone injection in my spine scheduled for this week and a referral to physical therapy, both measures to try and help my strength return.

I'm starting to wonder if there isn't a bit more to personal trainers' knowledge of "Optimal Exercise" than this. (Or maybe you are just talking to lousy personal trainers?)
