发明名称 Belt tension exerciser
摘要 A belt tension exerciser is provided with a rigid transverse handle which is longitudinally connected to an elastic band or belt to form a closed loop. The effective diameter of the loop measured in the direction of an exercising force may be changed thereby to adjust the expansion tension in the belt. The handle may be turned on its axis relative to the belt to permit a variety of exercise movements without adjusting one's grip.
