I have spent a year working on combating my back pain and I can tell you that the musculoskeletal system is exactly that - a system. The joints and muscles all work in concerted effort to move and this idea of isolated muscular contraction is a bit like pure functions in Haskell: ultimately pretty useless without IO. The core and spine is crazy complex. For starters I've learned a whole bunch of new muscles: glute medius/max, QL, serratus, interior/exterior obliques, multifidus, upper/lower/transverse abs, inner thighs, quads, hamstrings, hip extensors/flexors, lats, spinal extensors/flexors, rhomboids, upper/lower traps, pecs minor/major, levator scapulae... That sounds like I've just rattled off some anatomy but literally all of those network together to mobilise your spine and any one of those being out of whack can cause cascading and coupling issues of other nodes in the network. Glute weakness for sure is one of them so could any of the other ones...

This is very well articulated, but very disappointing to see so-called expert in their field orthopedic doctors advise their patients with the exact opposite.

Great illustration. I'm all about functional strength. There is a big difference between being able to pick up and throw 50 pound sacks of potatoes and the isolated exercises most of us do on machines. Total body strength seems far more useful.

  Don't do machines, they are really not that good for most uses. The fringe usability I can think of - competition bodybuilders, training around injury of professional athletes. That's probably it. Anything else ain't worth it. People often do max 1 specific muscle with them, ie biceps or chest to impress and fight low self-esteem, but that's generally not a good way either. As mentioned, muscles work in complex groups, and having 1 part way stronger than the rest will lead to injuries in real world usage. And injuries mean you will lose it all, and possibly worse.

Very well said. I've had trouble knowing where to start, sometimes spending days working on the wrong part of the system, playing wack-a-mole because I hadn't figured out the right root of my pain. Going to PT helped a whole lot, reading Robin McKenzie and Jim Johnson is great, but I also really like Jeff Cavaliere's technical explanations on his ATHLEAN-X YouTube channel [1]. He's a physical therapy and strength coach that gets crazy on his body with a magic marker and shows you how a chain of issues drives common problems. That deepened my understanding a lot, layering on top of all the other resources.
