I'm not sure that I agree with a lot of that article, but one piece really resonates with me. I had a chronic hamstring injury from sprinting (tendinitis, with a couple recurring minor pulls over the years) and physical therapy was a complete waste of time. The first physical therapist I went to told me that it would take over a year of sessions to recover from a grade 1 tear (which is absolute bullshit). She had me doing a bunch of different weird balancing exercises and working with elastic bands. I dealt with this injury for years until I started doing 1) foam rolling and myofascial release, and more importantly 2) squatting, deadlifting, and olympic lifts. The difference was almost overnight, and I haven't had a single issue with my hamstring in years now.
