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. Cardium 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. Each user can get tokens for physical activity with the fitness tracker. Mining pool uniting or connecting to an existing on the territory of the gym, the production of tokens commensurately increases. Tokens obtained as a result of mining can be used in the marketplace. It can be personal trainers, gyms, purchase of the relevant goods and services from the partners of the project.
