I can't stress this enough. So many of my peers have complained about back pain and other physical ailments, as if it was an unavoidable part of turning 30.

No, it didn't just suddenly appear the moment you turned 30, it's the symptom of accumulated damage from a sedentary lifestyle.

For what it's worth, I've managed to get a lot of them into fitness, and they're doing much better now
