Abstract: A strike training attachment for a heavy bag may include a ball member sized according to the diameter of a typical adult human fist. The ball member may be resilient. The strike training attachment includes a loop member disposed on an outer surface of the ball member. The loop member may be attachably co-operable with a hang-mounting member of a heavy bag.

Abstract: A punching bag system includes a punching bag that is suspended from a supporting structure. In this way the punching bag is positioned to be struck during striking training. A support is coupled to and extends upwardly from the punching bag and the support is coupled to the supporting structure. A plurality of ball units is provided and each of the ball units is removably coupled to the support. Each of the ball units abuts the punching bag thereby facilitating each of the ball units to be selectively struck during striking training.
