This article doesn't address the problem.. I can't add workouts in the fitbit app to my charge 5. How do we access the 20 promised activities in the advertising? I go to settings and activity and wellness and there are only 7 auto recognized activities. I don't see anything in the app about yoga, etc.
Kd887,
Refer to the article shared by JohnnyRow in this thread.
When you get to the exercise shortcut, there may be the maximum exercises already there, swipe to delete at least one and tap the PLUS SIGN...that will send you to a list that includes yoga and others.
Just in case anyone finds this thread and wants to see a video demonstrating how to customize the Charge 5 exercise shortcuts, I made a video here: https://youtu.be/vsnhs3JyH8M
