Abstract
A hypo-allergenic, latex-free, durable, versatile resistance exercise device in the form of a continuous, seamless loop comprised of a thermoplastic elastomer with an elastic range of 10-12 times resting length to allow resistance in a full range of motion and with thickness of 0.5 cm to 1.6 cm to allow the exercise device to stay in place without rolling up or pinching, thereby increasing the comfort for the user. In another embodiment, the device is a resistance band comprised of a first end and a second end and one or more grip holes through the first end and the second end which provide a means of facilitating grip for a user as to prevent or lessen the accidental release of the resistance exercise device.

17. A method of producing a resistance exercise device using injection molding comprising the steps of:
-
heating and mixing a thermoplastic elastomer material in an extruder to a temperature in excess of 175 degrees centigrade; extruding said thermoplastic elastomer into a heated injection cylinder; injecting said thermoplastic elastomer into a heated centrifugal aluminum mold while said centrifugal aluminum mold is spinning at a rate of 100 to 350 RPM; cooling said centrifugal aluminum mold as it continues to spin until said thermoplastic elastomer has cured enough to maintain its shape while handled; stopping said centrifugal aluminum mold; removing said thermoplastic elastomer; and curing said thermoplastic elastomer by cooling in air or liquid. - View Dependent Claims (18, 19, 20, 21, 22)
