Fitness tracker or digital personal coach: how to personalize training

The use of activity tracking systems promises support in meeting physical fitness goals. This support generally focuses on an improved self-awareness based on the review of own fitness data, sometimes enhanced by social features like performance comparison. We see a demand for a goal-driven support of fitness goal achievement to be addressed by a digital coach. The digital coach identifies strength and weaknesses of the subject, generates a training plan, motivates and helps, just like a real coach. Such a digital coach will highly benefit from the activity tracking system data which is used to personalize the training plan based on performed activities.
