I've never heard this! I'm super glad I opened this thread now, I could easily have seen myself doing something like this some day. Thanks.
I used to throw out my back every year or so, usually from bending over or for no reason I could see (maybe I overreached, as above, without connecting it to the pain). I started going to the gym three years ago, doing lots of deadlifts, squats, and core exercises, and it hasn't come back yet.
Last paragraph is exactly what happened. Feels terrible, but is quite sobering.
I said out of shape and I SHOULD correct that. Being out of shape contributes, but mostly because we/you just aren't moving your body in the most optimal way it should move. A big part of functional fitness, as I described, is understanding how your body moves. So if I reach for something, beyond being in shape, I also know where my center of gravity needs to be my muscle groups have the muscle memory to support me extending my body out, and if I have to stretch I know how to transfer power from the start of the stretch to the reach, etc.
Mostly that is all just a detailed and fancy way to describe what most people think is "being in shape".. but it's important I feel to point out. Going to the gym and training in functional fitness (usually not machines) is more than just lifting weight. It's teaching your body how to move properly.
Yes this is an ad (though I don't actually know the gym) and yes it's on Facebook but when I describe this to people this is exactly what I'm talking about.

I tremendous trainer once said to me "people who have terrible form in the gym are more likely to hurt themselves reaching for something in the cupboard at home than they are to hurt themselves lifting weight at the gym". This FLOORED me.. but it's true. We live lives of extreme convenience where we never have to squat down, never have to put our arms above our heads for any strenuous work, never have to jump, etc. These are things that every animal knows naturally from birth, us included, and by age 5-8 we lose virtually all of it because we've eliminated the need for it from our lives (and most importantly from our children's lives)
