Abstract

Disclosed is a hand-grasped exercise unit to assist in reducing wrist and hand pain during exercises such as yoga. The device, normally used in pairs, is constructed for a user to rest the heel of the palm, fingers, and base of the thumb while engaging in exercises normally done in direct contact with a floor or other hard surface. The device comprises a frame having an upper platform, and a support base with two orthogonally-oriented side walls and a rear wall. An opening allows a user to insert four fingers of the hand between the two side walls and grasp a rounded lip on the upper surface of the unit. A main foam layer and a secondary foam layer are affixed to the top surface of the upper platform. The two foam layers are enclosed by a fabric cover to provide additional comfort.
