You can adjust the level of your training program to start over or simply level down if you feel the app moved you up too quick.
Go to Settings > My program
Tap on your current objective (Ex: Objective 2 - Basics of Contraction Quality)
At the bottom of the screen, you should see a card
Tap it to level down
On the pop-up window, choose the level you want to go back to
Confirm
Et voilà
You can go back to training normally, the new selected level will be played.
⚠️ If you’re at level 1 of objective 2, you cannot level down to the first workout. To retrieve content on how to use Perifit, see here
⚠️Note that at this stage, if you choose to level down manually, you will not be able to level back up manually to levels you had previously reached and instead will need to earn the "perfect contractions" again to level up.
