> This is also the basis for exercise - your muscles and tendons are damaged when you work out, but they get rebuilt stronger
This is an outdated view, evidence shows muscle/tendon growth/adaptation occurs primarily via mechanical tension and metabolic stress, with damage playing a minimal or even counterproductive role. hypertrophy happens despite it, not because of it.
