Hello @Secline31
Depending on how much you move, you could let it detect automatically or choose an Exercise Shortcut like 'Workout' and then rename your session later in the App on your phone.
To load up the shortcut, tap your profile picture in the App on your phone, then Charge 5. Tap Exercise Shortcuts, delete one by swiping left, then tap on +Exercise Shortcut and choose Workout. Sync your Charge 5 to load it up.
When you've finish exercising, tap on the Exercise you want to rename. Tap the small white arrow in the top right of the screen across from Categorize Exercise and then enter the Exercise you want in the search box and select it.
I hope that helps!
