Abstract
Abstract The exercising device comprises an elongated elastic cord with a foot-receiving loop formed at each end and a hollow hand grip with an axial bore extending from end to end with a longitudinally extending split permitting one or two lengths of the elastic rope to be inserted into the bore. The hand grip may be squeezed by the hand for causing the wall of the bore to frictionally grip the rope. The hand muscles are exercised by this squeezing action on the hand grip and the arm and shoulder muscles are exercised when the hand grip pulls on the rope to elongate it.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
163 words
An exercising deviced comprising: (a) an elastic cord having a loop at each end to permit the loops to fit over one or both feet or be grasped in the hand of the one using the device; (b) a resilient hand grip means having an axial bore extending throughout its length with a radial cut coextensive with the bore and extending from the bore outwardly to the periphery of the hand grip means so that the two walls of the radial cut may be forced apart to permit the entrance of one or two elastic cords into the bore; (c) said hand grip means being squeezed by the user with sufficient strength to frictionally connect said grip means to said cord or cords, whereby the hand muscles are exercised; and (d) said hand grip means thus frictionally gripping the cord or cords can be pulled to elongate the cord or cords, thereby simultaneously exercising the arm and body muscles coordinated with the exercise.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
64 words
The combination as set forth in claim 1 further defined by the peripheral surface of said hand grip means being formed in the shape of the handle of an instrument employed in a particular unilateral sport such as a tennis racket or a golf club for use of the device in a series of exercises for groups of muscles employed in said particular sport.
