Set a Cardio Goal for yourself in the “Plan” tab of your adidas Training app. All the activities (running, walking, biking, hiking, etc.) you track with your adidas Running app are synced automatically.
The Cardio Goal can be set at the end of every week together with the number of training sessions for the following week. Just set the number of minutes you want to spend on cardio training in addition to your adidas Training workouts.
