发明名称 Exerciser
摘要 An exerciser has a base and a rocking plate. The rocking plate is rotatably attached to the base with a ball joint. Consequently, a user can swing or twist body, rotate ankles and develop feet muscles when the user steps on the rocking plate to keep balance. The exerciser can exercise the lower part of the body of a user. This exerciser is more versatile than the prior art.
