Definitions
- the present invention relates to an apparatus for an abdominal exerciser device, and more particularly, to an apparatus for an abdominal exerciser device in the general shape of an adult human cervical spine which acts to fix the position of the cervical spine and neck during the exercise movement and thereby isolates the abdominals and reduces neck strain.
- abdominal training devices While many various types of abdominal training devices have entered the abdominal muscles exercise market in the last ten years, there are just as many problems associated with them. Some are bulky and thus not very portable or easy to store. Others may potentially injure users through neck or back strain, or do not provide the user with feedback when they are not performing an exercise movement with technical precision (i.e., performing the exercise incorrectly, which can both reduce the effectiveness of the exercise and potentially injury the exerciser).
- one example of a popular abdominal training device is the “Ab Roller”. While it is designed with padding to cradle the neck, the fixed arc of motion due to its shape limits the exerciser to a range of motion which may possibly be unnatural for any particular user. It is also not very portable or easily stored. And, it does not reduce neck strain as the device is not based on the natural curvature of the human cervical spine.
- abdominal exercisers were having issues with doing even a basic crunch, not because of abdominal muscle failure, but rather because of neck pain or injury, to such a degree that such exerciser stopped training with the abdominal crunch exercise movement.
- a review of the abdominal exercise device market reveals that none of the exercise devices work for someone who is just beginning to work out and can train abdominal muscles without potentially causing injury to the neck, and at the same time make it very challenging for an elite athlete.

- the device is constructed with three major components: the device spine, the cushion assemblies, and the hand straps.
- the device's spine mimics the general curve of the adult human cervical and upper thoracic spine and provides attachment points for the cushion assemblies in the proper spacial relationship to accomplish the purpose of proper positioning of the exerciser's cervical and thoracic spine (i.e., neck and upper torso) during exercise.
- the cushion assemblies act as interface, or contact points, between the exerciser's body and the abdominal exerciser device. Contact between the exerciser's body and the cushion assemblies during exercise is maintained by means of force applied by the exerciser through the use of the straps attached at points to the device spine.

Abstract
An apparatus for an abdominal exerciser device in the general shape of an adult human cervical spine which acts to fix the position of the neck and cervical spine during a stomach crunch exercise movement is presented. The abdominal exerciser device comprises three major components: the device spine, the cushion assemblies, and the hand straps. The device spine is a bar or tube curved to follow the adult human cervical and upper thoracic spine and provides attachment points for the cushion assemblies and straps. The cushion assemblies are contact points for the exerciser's head and upper back, while the straps allow the exerciser to keep contact with the exerciser device during the exercise movement with minimal force.
Description
- The present application claims the benefit of U.S. Provisional Application, Ser. No. 61/316,884 filed Mar. 24, 2010, the disclosure of which is hereby incorporated by reference.
- The present invention relates to an apparatus for an abdominal exerciser device, and more particularly, to an apparatus for an abdominal exerciser device in the general shape of an adult human cervical spine which acts to fix the position of the cervical spine and neck during the exercise movement and thereby isolates the abdominals and reduces neck strain.
- While many various types of abdominal training devices have entered the abdominal muscles exercise market in the last ten years, there are just as many problems associated with them. Some are bulky and thus not very portable or easy to store. Others may potentially injure users through neck or back strain, or do not provide the user with feedback when they are not performing an exercise movement with technical precision (i.e., performing the exercise incorrectly, which can both reduce the effectiveness of the exercise and potentially injury the exerciser).
- For instance, one example of a popular abdominal training device is the “Ab Roller”. While it is designed with padding to cradle the neck, the fixed arc of motion due to its shape limits the exerciser to a range of motion which may possibly be unnatural for any particular user. It is also not very portable or easily stored. And, it does not reduce neck strain as the device is not based on the natural curvature of the human cervical spine.
- Another successfully marketed device is the “Ab Circle” family of abdominal training devices. On these devices the exerciser must kneel, and therefore is off of the ground. Additionally these devices are bulky and not easily stored.
- Smaller devices, such as the “Ab Wheel” and “Ab Slide”, while smaller and thus easier to store, do not allow for a supported nature of the exercise movements, especially so for less athletically competent users.
- Additionally, many abdominal exercisers were having issues with doing even a basic crunch, not because of abdominal muscle failure, but rather because of neck pain or injury, to such a degree that such exerciser stopped training with the abdominal crunch exercise movement. A review of the abdominal exercise device market reveals that none of the exercise devices work for someone who is just beginning to work out and can train abdominal muscles without potentially causing injury to the neck, and at the same time make it very challenging for an elite athlete.
- Accordingly, the present invention is directed to providing an apparatus for an abdominal exerciser device designed to maintain stabilization of the cervical vertebrae while performing specific abdominal exercises without significant engagement of supporting musculature in the cervical region, isolate the abdominal muscles during exercise, provide instant feedback to the exerciser when the device is not properly used, be simple to use, be portable, and be easy to store.
- The device is constructed with three major components: the device spine, the cushion assemblies, and the hand straps. The device's spine mimics the general curve of the adult human cervical and upper thoracic spine and provides attachment points for the cushion assemblies in the proper spacial relationship to accomplish the purpose of proper positioning of the exerciser's cervical and thoracic spine (i.e., neck and upper torso) during exercise. The cushion assemblies act as interface, or contact points, between the exerciser's body and the abdominal exerciser device. Contact between the exerciser's body and the cushion assemblies during exercise is maintained by means of force applied by the exerciser through the use of the straps attached at points to the device spine.
- There is described herein an abdominal exerciser device for use by an exerciser to exercise the abdominal muscles in a crunch exercise movement, the device comprising: a device spine, having a convex curve and a concave curve; a head cushion assembly, attached on a dorsal side at one end of the device spine; a back cushion assembly, attached on a dorsal side at another end of the device spine; and at least one strap, attached on a ventral side at both ends of the device spine, wherein the head cushion assembly is a contact point for the exerciser's head, the back cushion assembly is a contact point for the exerciser's upper back, and the at least one strap enables the exerciser to maintain contact with the head cushion assembly and the back cushion assembly during the crunch exercise movement.
- Additionally described herein is an abdominal exerciser device to fix a proper position of an exerciser's neck during a crunch exercise movement, the device comprising: a solid bar modeled on the general curvature of a cervical and intercepting thoracic regions of a human spine; a head cushion, for placement of the exerciser's head, attached at or near to a first end of the solid bar; a back cushion, for placement of the exerciser's upper back, attached at or near to a second end of the solid bar; and a first and second Y-shaped strap, each Y-shaped strap attached on the top of the Y-shape at each end of the solid bar, wherein the exerciser grasps one Y-shaped strap at the bottom of the Y-shape in each hand and applies a minimal amount of force to maintain contact with the head cushion and back cushion during the crunch exercise movement.

FIGS. 11 , 12 and 13, the use of theAbdominal Exercising Device 100 is shown. An exerciser places the device on a flat (but not necessarily level) exercise surface with thecushion assemblies strap device 100. The exerciser then lays supine on the exercise surface placing his/her head on thehead cushion assembly 3, with theback cushion assembly 2 contacting the exerciser's upper back centered on a horizontal plane roughly equal to the level of the shoulders (i.e., the vicinity of the T3 vertebrae of the thoracic spinal region). The long axis of the device spine 1 should follow the long axis of the exerciser's spine with the peak of the cervical spine arch and the peak of the device spine'slarge curve 10 generally in vertical alignment. The exerciser's feet will be flat on the floor. At no time should a typical human's spine contact the device spine 1. - When comfortable, the exerciser will grasp with each hand a
handhold 22 of eachstrap straps - To begin the exercise movement (i.e., a stomach crunch), and with eyes facing up, not forward, and the head fully in contact with the
head cushion 3, the exerciser will apply the least amount of force necessary through thestraps exerciser device 100 as the exerciser contracts the abdominal muscles to perform the first half of an exercise repetition. The exerciser will continue to apply the least necessary force, through thestraps -
Straps device 100. - Referring now to
FIG. 14 , if during the exercise the exerciser changes the natural resting curve of the cervical spine through head movement (e.g., lifting the head), the exerciser should feel the device slip or move from the original points of contact with the body at the rest position. This is the instant feedback feature of the device. The exerciser should return to the start position, reposition to achieve the proper contact with the device and begin the exercise movement again. - Additional abdominal exercises may be performed by raising the exerciser's feet to a variety of heights, varying leg extension, and as well as twisting the body (torso) to lay the exerciser's legs to one side or the other to exercise oblique abdominal muscles.
- In the foregoing description, the method and apparatus of the present invention have been described with reference to specific examples. It is to be understood and expected that variations in the principals of the method and apparatus herein disclosed may be made by one skilled in the art and it is intended that such modifications, changes, and substitutions are to be included within the scope of the present invention as set forth in the appended claims. The specification and drawings are accordingly to be regarded in an illustrative rather than a restrictive sense.
