Champion Barbell Reactor Fitness Balls

These are soft, pliable balls designed to fit comfortably in the palm of your hand. They have enough structure to hold their shape during movement but are soft enough to grip easily without straining your fingers.

No, these are designed specifically for matwork, Pilates, and toning exercises. They are not intended for high-impact activities like wall balls or slams, which could damage the vinyl casing.

By adding a small amount of weight to your hands during arm movements, these balls force the muscles around your shoulder girdle to engage more actively. This extra resistance helps you maintain better alignment and control throughout your range of motion.

They are filled, providing a consistent, stable weight that adds resistance to your exercises. They are not hollow.

Because they are soft and have a slightly textured vinyl surface, they are less prone to rolling away than hard plastic or rubber weights. However, they are still spherical, so it is best to keep them on your mat when not in use.
