The epidemic of excess weight and obesity is gaining momentum every year, especially in developed countries. Unfortunately, this is not another story to drive people into the gym, but a very real threat. According to scientists, by the year 2025 a fifth of the world’s population will be affected by this disease. Lack of motivation, societal shaming and its harmful impact all have a very strong impact on people following an unhealthy life plan. Cardium offers its own motivation for one to always be rewarded for any athletic activity – from the highest intensity to the even the modest exercise. Lack of motivation and small knowledge of sports are the main obstacles to engaging people through sports, so far nothing has been done to tackle this problem. Our project aims to change this situation. The key element of the ecosystem is Cardium fitness tracker, around which other interactions are built. Various techniques that we implemented in our knowledge database will facilitate the process of engagement.
