On the strength workout selection screen, you'll see a toggle for exercise tutorials.
Green showing — tutorials are on. The exercise will be demonstrated before you begin.
No color — tutorials are off.
Toggle it on or off before your session based on your preference.
If tutorials are on but you already know an exercise, you can tap Skip Tutorial within the workout to move straight to it.
Set your preference once, carry it everywhere
Rather than toggling each time, you can set a default in your global preferences:
Tap the AlterMe icon in the top left
Select Preferences
Tap Manage Tutorials
Select On or Off
This will preset your tutorial toggle to your preference every time you start a strength workout — no need to adjust it session by session.
