Sports and fitness are a combination of stamina, reflex and agility. Majority of the products available in the market work on a user's stamina. Very few products cater to training one's agility and reflexes. Also, many fitness apps focus on reflex and agility but do not track the user's progress. Atom is designed to help users improve their agility and reflexes through a set of synchronized self-registered physical targets(SSPT) that use light and sound to guide them through a training regime. The system includes touch-sensitive SSPT that can be tapped with hands, knees, or feet to enhance coordination, balance, and strength. It connects to a companion app that provides a range of sports activities, home workouts, and competitions, and tracks user progress to create personalized workouts. This product is ideal for group trainers, performance coaches, fitness studios, sports clubs, and gyms.
