On Apple Watch, there is an option for the workout app to ask you if you’re finished working out if your heart rate goes down. I ALWAYS forget to stop my walking workout and this is great because after a minute or two, Apple Watch will ask if I’m finished with my workout. I LOVE this feature. For some reason, Trainerize doesn’t link with my Apple workouts so to track my walks, I use Trainerize. But because I often forget to stop my workout, I end up discarding it when I see it’s still running way later. So I would love for either an added reminder feature, or better yet, let workouts from Apple sync to Trainerize (right now Trainerize workouts sync one way to the Health app).
