It drops the heavy leg day and swaps in mobility work. Your workouts adapt after each session, prioritizing your long-term health over just cranking out more reps. I’m excited to share how Dorsi tailors your workouts daily based on your unique feelings and needs. Nearly 73% of new gym-goers quit within three months—not because they’re lazy, but because their plan doesn’t fit their life. Decision fatigue alone—picking from 20 exercises, rep ranges, and rest periods—kills motivation before you even start. Dorsi, an adaptive AI strength coach, fixes that by building your workout plan straight from your Apple Watch data and activity history. During a recent 12-week trial, users reported feeling stronger and more capable, achieving strength gains that were 34% quicker than those using traditional plans. The system adjusts load and volume based on how you’re recovering, cutting perceived exertion by 18% while keeping progress on track. I’m excited to share how Dorsi tailors your workouts daily based on your unique feelings and needs. ## Start with your baseline assessment Your AI agent needs a starting point. Spend 10 minutes completing a short fitness test—push-ups, squat max, or a 1-mile run. Or grant access to your Apple Watch history. This data sets your initial training zones. Without a baseline, the AI guesses. With it, your plan targets your actual capacity. ## How does the AI tailor your weekly workouts? It crunches your baseline, goals, and recovery signals. For strength, it picks exercises that hit weak points. For volume, it sets sets and reps just above your current max. If you mark a session as hard, next week's load drops by 10%. The plan isn't static—it's a living doc that learns you. ## Run your first session with real-time feedback Fire up the app on your phone. The AI guides each set: it shows the weight, reps, and rest timer. After a few reps, it may nudge you to speed up or slow down. Miss a rep? It adjusts the next set. This isn't a pre-printed PDF—it's a coach that watches and adapts. ## Adjust plan weekly using performance trends Every Sunday, review your summary. Did your squat weight plateau for two weeks? The AI adds a deload week. Did you nail all reps? It bumps intensity 5%. You don't need to guess—the data speaks. Stick with the process for 3 weeks, then tweak one variable at a time.
