The IntelliGym is not a video game, but is a tool designed to improve football intelligence and improve performance on the field. Video games are designed for fun and enjoyment, and as such, they do not challenge the brain the same way that IntelliGym does. Using the IntelliGym can still be a fun experience, but it is first and foremost designed for performance, which if used correctly, is guaranteed to work.
The IntelliGym is based on over 30 years of cognitive science supporting its results. There are no fantasy stories or complex graphics. The IntelliGym simulates the cognitive demands that are placed on the brain on the field during a game. The program challenges these cognitive processes into the athlete’s subconscious until they become more instinctive. The program also uses AI to adapt and tailor the training levels to each player’s individual strengths, weaknesses, and learning curves.
