ABSTRACT A hitting device particularly adapted for use in the practice of martial arts, such as karate, which may be mounted on a vertical wall or post and carries a desired hitting surface. The bellows portion contracts when contacted axially to absorb the impact of the hitting force. Closable vents are provided in association with the bellows portion to allow for variation of the compressibility of the bellows, thereby varying the resistance to the hitting force by the hitting device. A force-indicating assembly is also mounted on the hitting device for approximately indicating to a student the hitting force applied.
