A speedball is primarily used to increase hand-eye coordination and will improve a boxer’s conditioning. You’ll recognize a speedball as being inflated and attached to a wallboard, although they can be freestanding but difficult to find in adult sizes. When punched, they quickly swivel and bounce back, so you have to react quickly and work on your footwork. Generally, the more air in a bag, the faster it will respond. The smaller the ball the harder to hit, so maybe start with a daily size and work right down to a peanut or mini size.
Best for: Improving hand-eye coordination. Ideal for beginners and all levels.
Maize balls are typically small hanging punch bags used to specifically train your head movements and generally much smaller than a Maize Bag which is used for hooks and uppercut punches, much like uppercut bags. They are perfect for building up defensive moves and can easily fit in smaller spaces. Maize bags filled with fake granules or rag and fake granules will be heavier and will increase your endurance.
Best for: Working on head movement and uppercuts.
Free-standing punch bags come with a base that can be filled with sand or water and are usually easy to move around a gym and for placing into storage. The taller versions are primarily designed for punching and kicking workouts and therefore the heavy-style bags with bigger bases don’t move from their position when kicked. Also ideal for punching, they provide a solid, all-around exercise and are great for beginners and professionals alike and great for home use when a bag cannot be hung from the ceiling or walls.
Best for Kicking workouts and all-around training.
