System and method for providing a fitness experience

Abstract

Methods and systems for providing a fitness experience to a user. The system comprises a punching bag defining an outer non-planar surface adapted to receive strikes of the user, a sensor configured to generate data about strikes applied by the user on the punching bag, an image projecting device configured to project a dynamic content on the outer non-planar surface of the punching bag and processor communicably connected to the sensor and the image projecting device. The processor is configured to dynamically adjust the dynamic content projected on the outer non-planar surface based at least in part on data provided by the sensor.
