It sounds like you've finished your workout level, congratulations!
You can check this by
- Pressing "Workouts" tab
- Press "View" under Your Plan
- Scroll through your guide to see if all of your workouts are complete
If they are it's time to go to the next level! If this is not the case you may have moved your workouts out of sync and would suggest to do the following:
- Press "Workouts" tab
- Press "Change Plan"
- "Select Program"
- Scroll down to choose the week you wish to continue on
If you have already completed some workouts in the same week it will cause the stars to be lost however you will be able to put your workout back in the correct rhythm.
