Abstract:

An apparatus and method to exercise and strengthen arm and core muscles and improve muscle coordination includes a main body for being manually grasped and first and second arm units constructed and arranged to generic centrifugal forces to create exercise resistance. In an exemplary embodiment, the arm units include shafts longitudinal axes inclined to the longitudinal axis of the main body and mounted to spin or gyrate with respect to the gripped surface of the main body. The arm units are advantageously weighted to supplement the centrifugal forces generated by the gyrating motion, thereby to create exercise resistance.
