It watches your heart rate variability drop after a bad night's sleep, your max heart rate climb during a PR attempt, and the recovery trend after a hard week. Then it tells you exactly what your body needs today. Dorsi brings this to your Apple Watch: real-time decisions based on your history, not generic rules. Every set and rest interval feeds the model. The page below walks through the data streams and the logic that turns them into your next move. Most people overthink their workouts. They spend more time planning than exercising, then wonder why they skip the third session of the week. We’ve covered the symptoms before, “5 Signs You Have Workout Decision Fatigue (And What to Do About It)”, and the numbers bear it out. That’s where an AI workout tracker comes in. Instead of browsing endless routines, you get a plan built on your history, your recovery, and your available gear. Dorsi does exactly that, adapting each session based on your recent performance and readiness. One study found that personalized program recommendations boost adherence by 30% over generic plans. The rest of this page unpacks the mechanics, how sensors, algorithms, and feedback loops turn raw data into a workout you'll actually finish. ## Log three honest sessions before trusting the numbers The AI needs raw input before it can guess your next set. Go through three full sessions without skipping warm-ups or fudging rep counts. Let it see your actual 8-rep max, not what you wish you could lift. This setup phase is the difference between a coach that learns and one that spits out random numbers. ## How often should you retest your one-rep max? AI models drift if you never update your inputs. Retest your max on the big lifts every four to six weeks. Don't have a true 1RM? Take a single AMRAP set at a moderate weight and plug it in. The tracker adjusts faster when you feed it real data. Stale baselines mean stale recommendations. ## Compare predicted vs actual on the same lift weekly Pick one compound lift each week, squat, bench, or deadlift. Note what the AI predicts for your working sets versus what you actually grind out. If the gap keeps growing, something is off: sleep, nutrition, or accumulated fatigue. A narrowing gap means the model has you dialed in. ## Use the app's deload triggers, don't wait for injury Most AI trackers detect accumulating fatigue before you feel it. When your bar speed drops by 10% across two consecutive sessions, that's the signal. Act on it. A planned deload week, five days at 60% volume, keeps you from stalling or snapping a tendon. Trust the algorithm on this one.
