Balls and Swivels
Swerve balls or floor to ceiling balls are almost the same as Speed balls, the only difference is that the bag size shape and material may be different and that the cable system is attached to the ceiling and a clip on the floor - when the boxer places any motion on the ball, it tightly reacts by swinging fast towards them, the object is to swerve, punch, dodge and learn about co-ordination. The harder and faster they are hit - the more they rebound and react in different motions of angles, thus giving greater practice to the fighter.
Speedballs, are air-filled bags anchored at the top to a rebound platform parallel to the ground. Speed bags help a fighter learn to keep his hands up, improve hand-eye coordination and learn to shift weight between feet when punching.
