How can I add activities which are not listed in the list??

Tap on the workout app and scroll down to the bottom and tap on "Add Workout" then scroll down the list until you find a workout type you want then tap on it and it will be added to your list of workouts.

They are all there in alphabetical order,which one's don't you see?.
