Progression rules for loading tendons without triggering flares

We get this question in my inbox almost daily: how do you actually step up load week after week without ending up right back at square one with a hot, reactive tendon? In my work as a nurse and recovery coach, I see people fall into the same trap over and over. They feel good for three days, so they double the weight or add three extra sets. That is the heroic effort trap. Tendon rehab works just like sobriety work: boring, unsexy consistency beats massive spurts of effort every single time. Tendons adapt slowly because their metabolic rate is low compared to muscle tissue. Here is the basic framework I use with clients: 1. Increase only one variable at a time (volume or load, never both in the same week). 2. Use a maximum increase of 5% to 10% per week. 3. Assess the tendon 24 hours post-load, not while you are doing the lift. If you experience sudden severe sharp pain, visible swelling, or pain that keeps you awake at night, stop immediately and get evaluated by a physician. Those are red flags, not typical tendon adaptation.
