Hi, I wonder if it is possible to start an training exercise by tapping on the step counter, I only see an option to open S Health step counts but not one to start and training exercise, e.g start running.

Not possible with the current version of GWD… Would need to be a potential future feature…

You can reach up to the workout screen. Insert a transparent image and place it over the step counter. Set it as button and select double tap - > open app - > custom… Then on the custom app assign the following: com.samsung.shealth.exercise

This will open the appropriate screen in samsung health where you will see a workout button.

It is as far as I could get but I cannot go a step deeper as to start running or biking…

Hope this helps
