Heart Rate Zones • The Heart Rate and Resting HR detail pages now show your personalized Z1–Z5 heart rate zones, calculated using the Karvonen formula from your age and resting HR. Tap any zone to see a plain-language explanation and weekly training time recommendation. • Each workout in today's summary now shows a zone badge (e.g. Z3 138 bpm) so you can see at a glance whether your ride or run was a warm-up or a solid aerobic effort. • The workout history page for each activity now includes a zone distribution chart below the existing graphs — showing how your intensity was spread across zones for the selected period, with a plain-language verdict on whether the intensity was sufficient. • The Fitness Progression heart rate comparison now shows which zone each half landed in. If your zone shifted between periods (e.g. Z3 → Z2 at the same effort), it tells you what that means for your aerobic fitness. • Fixed an issue where the zone badge sometimes didn't appear on today's workout card.
