Abstract

A hand exerciser includes a hollow sphere that has four openings and a cruciform member is supported in the sphere. Two handle disks and two massage disks are rotatably connected to four ends of the cruciform member and respectively engaged with the openings. A rod extends from a center of the cruciform member and a spring is mounted to the rod and a tube is rotatably mounted to the rod and biased by the spring. A weight is connected to a lateral rod extending from the tube. The eccentric force by the weight when the sphere is rotated applies a force to the hands holding the handle disks or the massage disks.
