generally disclosed is an exercise device featuring two leg cuffs ; a large spiral constructed from a stretchable material connected to the leg cuffs ; a smaller spiral constructed from a stretchable material inside the inner loops of the larger spiral ; and two arm bands that are each coupled a leg cuff . the more specific aspects of the device are disclosed with reference to the attached figures . fig1 shows a front view of the device 1000 . as shown , the device 1000 consists of two leg cuffs 110 . attached to the leg cuffs 110 may be a large spiral 120 . within the inner diameter of the loops of the large spiral 120 , is preferably disposed a smaller spiral 130 . in some embodiments , the device 1000 will also feature stretchable tubing 131 within the loops of the small spiral 130 . in the figure , the large spiral 120 is attached to the leg cuffs using ball stops . ( see fig7 , 125 ) the small spiral 130 along with the tubing 131 is attached to the leg cuffs 110 by connecting a clip 132 to a ring 111 attached to the leg cuff 110 . in the preferred embodiment , the small spiral 130 is attached to the leg cuffs 110 by a snap clip 132 , but other mechanisms may be used to connect the small spiral 130 to the leg cuffs 110 . also attached to the leg cuffs 110 , in this embodiment , are arm bands 200 . the arm bands 200 may consist of tubing 210 and a handle 220 . in the preferred embodiment , the tubing 210 is attached to the handle 220 using a grommet 222 and ball stop 221 although other modes of connection are possible . the arm bands 210 connect to the leg cuffs 110 via a clip 211 around the ring 111 . in the preferred embodiment , a snap clip 211 connects the arm bands 210 to the leg cuffs 110 , but other connecting mechanisms may be used . fig2 is a detailed view of the spirals 120 , 130 . the large spiral 120 contains a core 121 inside of a casing 122 . the core 121 is preferably a braided strand of non - stretchable material , but could also be a bungee cord . a bungee cord typically consists of elastic strands surrounded by a woven seal , typically of cotton or polypropylene materials . the casing 122 is constructed from a sturdy , yet stretchable material such as foam . the smaller spiral is preferably constructed from a stretchable material . the preferred embodiment features tubing 131 between the loops of the small spiral 130 . the tubing 131 is preferably made from latex , but may be constructed from any stretchable material such as rubber or elastic . still referring to fig2 , in the preferred embodiment the large spiral 120 and the small spiral 130 are wound in opposite directions . in the preferred embodiment , the large spiral 120 is wound in a clock - wise direction and the small spiral 130 is wound in a counter - clockwise direction . when a user performs a leg exercise using the device 1000 , the two spirals 120 , 130 rotate in opposite directions . as acceleration is increased through repetitive body extremity movement , both spirals 120 , 130 produce energy directed toward the center . the rotation differential of the two spirals 120 , 130 produces a controlled and constantly applied energy release when the device 1000 is extended and contracted . speed acceleration and force are uniformly regulated through the full body exercise routine , which permits biomechanically correct muscle sequencing to occur , while also maintaining the body &# 39 ; s normal posture , stabilization , and flexibility through the performance of exercise . fig3 depicts a detailed view of the large spiral 120 , specifically the core 121 and the outer casing . fig4 and 5 depict the leg cuff 110 . the leg cuff 110 consists of a strap that is capable of forming a loop . one end of the strap of the leg cuff 110 features a hook and loop fastener . in order to form a loop , one end 113 is inserted into a belt loop 112 where the end 113 can be attached to the other half of the hook and loop fastener 115 . the leg cuff 110 is designed to be worn in the lower leg patellar area , but the size can be adjusted so that it fits around other parts of the leg . the leg cuff 110 features a ring 111 and a grommet 114 . the ring 111 is used to attach the small spiral 130 and the arm bands 200 to the leg cuff 110 and the grommet 114 is used to attach the large spiral 120 to the leg cuff 110 . the leg cuff 130 is preferably made from nylon . it may also be constructed from another fabric such as lycra or polyester , or it may be constructed from a flexible plastic material . the ring 111 is preferably a stainless steel “ d ” ring with a minimum tensile strength of 400 lbs , but it may be constructed from another metal or a strong plastic . in the preferred embodiment , the ring 111 is attached to the leg cuff 110 by encasing the ring 111 in a jacketed sewing method by sewing the jacket to the leg cuff 110 using ultra poly thread . fig6 is detailed view of the mechanism for attaching the large spiral 120 to the leg cuff 110 in the preferred embodiment . in this drawing the braided strand 121 is inserted through the grommet 114 ( see fig5 ). on one side of the grommet 114 is a ball stop 125 . on the other side of the grommet 114 is a stop button 124 . in addition to the ball stop 125 and stop button 124 , there is also a washer 123 , which serves as a tension holding plate . the washer 123 serves as a tension holding plate and there is one at each end of the spiral . the ball stop 125 is preferably a one - eight inch oblique nylon rope ball stop , but other ball stops can be used . the stop button 124 is preferably constructed from aluminum , but may be constructed from another metal or a strong plastic material . the washer 123 is preferably seven sixteenth inch stainless steel washer . fig7 is a detailed view of the mechanism that connects the small spiral 130 to the leg cuff 110 . the small spiral 130 is connected to the leg cuff 110 via a clip 132 . in this embodiment , the clip 132 is constructed from the same material as the small spiral 130 , which is a durable material such as metal or nylon . the end of the small spiral 130 forms a loop that is held in place with a stop button 133 . the clip 132 is inserted around the ring 111 during the manufacturing process . in this embodiment , the small spiral 130 cannot be removed from the leg cuff 110 . in an alternate embodiment , the small spiral 130 is attached to the leg cuff 110 using a hook , clasp , carabineer , or another removable mechanism . this way , the small spiral 130 can be detached in order for the user to perform an exercise that calls for less resistance . the small spiral 130 can also be replaced with another small spiral 130 with more resistance when an exercise calls for greater resistance . fig8 is a detailed view of the large spiral 120 , the small spiral 130 , and the tubing 131 . fig9 is a detailed view of the right side of the device 1000 . fig8 shows how all of the parts connect to the leg cuff 110 . the arm bands 200 are connected to the leg cuff 110 by the same ring 111 that connects the small spiral 130 to the leg cuff 110 . the arm band 200 is connected to the ring 111 via a clip 211 . in this embodiment , the clip 211 is constructed from a durable material such as metal or nylon . the end of the tubing 210 forms a loop and held in place with a stop button , tied knot , self -
