Hand, wrist, and forearm friction resistance exercise device

An isometric exercise device for the hand, wrist, and forearms which requires equal and opposite forces to move the device from and to initial positions, comprising:

• (a) an elongate bar,
• (b) handles encompassing each end of said bar disposed in position generally transverse of said bar,
• (c) means on said bar and on each said handle to mount said handles for manual movement about the ends of said bar for essentially universal motion, and
• (d) said means including an adjustable torque control to provide resistance to said manual movement to require muscular effort to achieve said movement.

In a muscle developing exerciser,

• (a) a solid elongate bar,
• (b) a solid spherical balls fixedly fit onto the ends of said cylindrical bar,
• (c) handle means mounted so as to capture each said spherical ball, and
• (d) means to hold said handle means together around said ball, whereby each said handle means frictionally acts on a line of contact on said spherical ball causing frictional resistance to movement of said handle means about the X, Y, and Z axes of each said spherical ball and movement relative to other said handle means.
