The Glow. Your muscle map now reads the last 7 days instead of resetting every Monday — train Sunday, still lit Monday morning. And it works both ways: hit a muscle hard 4+ days in a week and it heats up. Optimized — rest extends the glow. Also in this release: • Strength trend, honest: your PR line with per-day best dots — no more confusing decay curve. • Burpees now credit your chest, and the kettlebell swing muscle map got corrected. Existing logs recount automatically. • If a save ever fails, you'll see a calm heads-up and nothing is lost. • Faster history and PR lookups on big logs.

New in 3.1: - 3D exercise demos: squat, bench press, deadlift, overhead press, and barbell row now show an animated figure performing the lift on the exercise page. - Training Load: each workout now writes a session effort score to Apple Health (iOS 18+), so Apple Fitness Training Load fills in without the rating prompt. Tap to correct it on the workout summary. - Start a watch workout from your phone. - PRs, clarified: the flame now always means a new all-time best estimated 1RM. More reps at a given weight earns a quieter "rep best" tag. - Bodyweight exercises log reps only; add a vest or band when you use one. Fixes inflated PRs from body weight typed as added load. - Fix mislogged sets: press and hold any past set to edit or delete it. - Plate math under barbell sets shows the per-side loading. - Customize which tiles show on Fuel. - Assorted fixes, including more reliable workout saves from the watch.
