Abstract
Abstract 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.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
99 words
An exerciser operable as a closed loop formed by a longitudinally expandable elastic band which engages a rigid handle member, the improvement comprising means for adjusting the length of band between the ends of the handle to effect a change in the force required to expand the band radially outwardly during a selected exercise, the handle being rotatable on its axis relative to the band and comprising a pair of separable concentric hollow cylinders slidably engageable one within the other for longitudinal movement back and forth in one direction to effect a change in the length of the handle.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
27 words
The exerciser of claim 1 in which the elastic band comprises an endless belt which passes longitudinally through each of the concentric hollow cylinders of the handle.
