What's a Cobra Bag?
The cobra bag is a type of reflex punching bag that incorporates a football-sized ball on top of a rod or pole that is able to flex back and forth. The cobra bag is one of the best training tools for boxing training. It's ideal for developing a high level of hand-eye coordination and defensive boxing skills.
