MUSCLE FRESHNESS Every exercise row carries a recovery dot, green, yellow, or red, so you know which movement patterns are ready for another hard session. Tap in for a per pattern recovery bar, last loaded time, and the workouts that contributed. STRENGTH STANDARDS See where your Squat, Bench, Deadlift, and Overhead Press rank against the rest of the lifting population, adjusted for your bodyweight, age, and sex. Per lift progress bars show how far you are from Intermediate, Advanced, or Elite. RECOVERY INSIGHTS Connect Apple Health and the app watches your HRV, sleep, and recent training load. When recovery looks reduced, a banner on Home suggests a lighter day. Every past alert stays in Progress so you can scroll back through the data that drove every recommendation.
