Abstract: A system for supporting a punching bag includes a bag portion mounted on a ring by straps. The ring is spaced away from the bag portion by the straps. The ring is in turn mounted by springs or chain to a plate and bearing assembly including a plate. The ring is the same circumference as the bag portion. As such, the straps are vertical. This prevents deformation of the bag.

Abstract: This bag can be used for punching, martial arts, and boxing. It is designed to have a holding mechanism that allows the user to see if they are hitting the bag directly. The user with incorrect punches, that are dangerous, makes the bag spin with the ball bearing in the holding mechanism. The bag spinning tells the user that they are incorrectly using the bag. The spring mechanism found in the holding mechanism absorbs hits from the user. The metal ring in the bag allows the bag to have even weight distribution in the bag which does not allow the bag to deform. The strap mechanism is made with a backing which does not allow the straps to rip. The lower section of the bag is sewn to the upper section of the bag. Only the lower section of the bag is made for hitting and is stuffed with a softer material in order not injure the user. The upper area of the bag is not for hitting and is made to store heavier material that forces the bag to always to by full.
