Cobra Bags Explained

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 that a boxer can have for developing a high level of hand-eye coordination and defensive skills. The interactive nature of the cobra bag makes it fun to train with. Even if you're not into boxing, but simply want a fun, interactive and challenging way to exercise your whole body, the cobra bag will give you that and more.
