Ball-shape brawn training device and ring thereof

Abstract

A ball-shape brawn training device includes a casing, a ring, a ball body. The ring is configured in the casing and movable relative to the casing. The ring includes a first pivot part and a second pivot part opposite to each other, a first ring section and a second ring section connected to the first pivot part and the second pivot part respectively. The ball body is couple to the first pivot part and the second pivot part and is rotatable relative to the ring. The second pivot part is composed of a first assembly portion and an assembly on the ring. As a result, when the ball-shape training device is equipped more additional elements, the ring can be quickly assembled to the ball body.
