Isn't everything mostly hype? After you have a certain minimal level of strength and cardio capacity, how much do those actually affect your life? From the article: "Although it can boost flexibility, the value of this is unclear, and no other measurable and significant benefit to stretching has ever been proven." The thing I had to learn the hard way was the value of flexibility. You can pump out squats and go for a jog, but if your knees and ankles hurt when you go down stairs, you have a problem. If you can't sit on the ground with your back straight, you have a flexibility problem. A lot of lower back pain comes from flexibility issues. What is the value of flexibility? Go visit a nursing home and see people who can barely move. Part of that is lack of strength, part is lack of cardio, and part is lack of flexibility. ---- Also, you should beware of lessons learned the hard way. A lot of times they are another way expressing a pain point, sometimes with a solution that worked - but that solution may not be optimal.
