Log activity or workout in the app

First, click the big orange plus sign in the bottom middle of your screen.

Choose the option "Register physical activity"

You can type what you did in the search bar, or scroll through All physical activities to find the exercise that matches closest to what you did.

Once you choose an activity, the date and time you logged it will automatically pop up (you can change this if you want it to reflect what time you actually did the exercise/ activity). You can adjust the duration to match how long you did the exercise. If you have an Apple Watch, FitBit, or any other smart watch that tracks your calories burned, you can update the energy section as well. Or, you can leave it as is and the app will estimate how many calories that type of activity usually burns.
