What's New - Exercise progress from any workout. Tap an exercise name on a completed workout to see its progress chart and history. It opens on that session, and you can close it and tap the next exercise. - Better history in the logger. An exercise's history in the logger now uses the same chart and records as Progress, covering the last 3 months. - Pull-ups, chin-ups and dips now chart an estimated max that includes your bodyweight. More reps at the same weight now shows as progress, and bodyweight and weighted sessions share one line. - Timed holds like planks and hangs now chart your longest hold. - Clearer RPE colors. On target or half a point over is green, 1 to 1.5 over is amber, and more than that is red. - Simpler form check feedback. Each exercise has one conversation with your coach. - Invite your coach from More › Programming if you don't have one yet. - Birth year now only accepts real years, so your Durability Score is calculated with your actual age. - Small fixes and polish.

The Durability Score is a strength retention metric that quantifies how well you maintain your strength as you age, based on powerlifting standards like DOTS normalization and IPF age coefficients. It helps you understand your strength longevity without needing to test your 1RM.
