Abstract
A boxing training partner comprised of a base, a figure body having two arms, a spring, a height adjusting device located in the base, a controller, and two arm extension devices. The controller controls the filling of gas bags, which are part of the arm extension devices, for causing the two arms to extend aperiodically, according to a predetermined sequence stored in a memory, so as to respectively give a blow. A pair of arch spring plates are placed in each of the two arms, for returning the two arms to their retracted position, each time after having been extended.
