Can I edit a workout l've already performed?Updated a month ago

Yes! Select the workout you'd like to edit from your log screen and tap the "Edit" button in the top right corner of the screen to change the rep count or add additional workout notes. 

If you did not complete all exercises in a given workout, you can resume the workout by selecting it from your Log screen and tapping the "Resume Workout" button. Select the incomplete exercises to perform. When you've finished all exercises tap "Done" in the top right corner. Tapping the "Exit" button may result in unsaved data.
