For years I had lower back pain. Finally I went to PT, and learned a lying-down lower back twist that would cause some faint cracking noises which brought immense relief.

Now after lots of lifting, and a much more muscular core, the pain and the ability to crack are gone.

My biggest life lesson is that weightlifting is not an optional activity that folks can enjoy if they choose. It's an absolutely vital activity for everyone outside of a very physical career.

But deadlifts are not necessarily for everybody: https://www.menshealth.com/fitness/a29265805/should-you-dead...
