Workouts are a killer is a good way.
I enjoy the sets that focus on different areas of the same body part. I curse the person who has me do a set that targets the same thing 😅. My body usually always fails near the end but the progress is noticeable. The app doesn’t always log the workout you’ve just completed. When trying to go to the next set sometimes the app backs you out and of course clears your time spent in the workout.
