ABSTRACT:
BACKGROUND OF THE INVENTION
This invention relates to exercise devices and, more particularly, to a flexible device to be grasped by the hand or hands for applying gradually increasing tension in stretching exercises.
Tensioning devices of the prior art for use in stretching exercises generally provide a spring or elastic elongate element with handles at opposite ends. The length may be adjusted to change the tension, but not during the actual stretching exercise. In stretching, greater benefit may come from greater tension. However, if this is applied suddenly, it may lead to discomfort or injury. If devices of the prior art are lengthened to reduce the threat of injury, the tension may not be great enough to achieve maximum benefit. If the length between handles is shortened to increase tension, the sudden application of great tension may cause injury.
SUMMARY OF THE INVENTION
It is, accordingly, an object of the invention to Provide a flexible exercise device that has handles that can be grasped to apply tension to the arms, in which the tension can be gradually increased by moving the hands closer together by moving a hand from one handle to a closer handle without ever releasing the hand's grasp on the device.
The device of the invention comprises a pair of spaced apart elongate side members with a plurality of spaced apart handles or rungs joined at their ends to side members.
The surfaces of the rungs and the side members are provided with corrugations or indentations that enable the fingers of the hand grasping a rung to move the hand along from the rung, along a side member and onto an adjacent rung without ever releasing the grip on the device. By this means tension on the arm may be continuously increased during an exercise without the dangers inherent in an abrupt tension increase.
