DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
With reference to FIGS. 1-8, an embodiment of an inclinable exercise device 100 including an embodiment of an abdominal (“ab”) crunch board 110 and method of using the same will be described.
Before describing the ab crunch board 110, the inclinable exercise device 100 will first be generally described. The inclinable exercise device 100 includes a vertical support member in the form of a ladder/tower 120 with a pair of vertical support members 130. Although two vertical support members 130 are shown, in an alternative embodiment, the tower 120 includes one or more vertical support members 130. Extending from the front of vertical support members 130 are catches 140.
Lower rails 150 are pivotally coupled to upper rails 160 to form an adjustable incline having a first end and a second end. A strut 170 is pivotably coupled to a base tube 180 at the lower end of the vertical support members 130 and is also pivotably connected to a rail pivot point 190. Lower ends of lower rails 150 terminate at a base tube 200.
A user support platform or glideboard 210 with rollers (not shown) rolls along the rails 150, 160.
Pulley supports 220 are connected to upper ends of upper rails 160. Attached to the pulley supports 220 are pulleys (not shown). Although not shown, a connector extends through the pulleys and connects to an upper end of the glideboard 210. The connector may be of any suitable well-known type, but is preferably a cable with handles at each end. The cable extends through the pulleys connected to the upper ends of the upper rails 160 and loops through a third pulley (not shown) attached to an upper end of the glideboard 210. The third pulley is positioned along the lateral centerline of the glideboard 210. This position allows for unilateral (i.e. one arm), bilateral (i.e., two arm) and static equilibrium (i.e. holding the glideboard 210 suspended by keeping a constant force on each handle) use. The cable should preferably be of sufficient length to extend through the pulleys and allow the exerciser to grasp one or both of the handles while the exerciser is on the glideboard 210 and the glideboard 210 is at rest.
In an alternate embodiment, the connector is two separate cables extending through the pulleys connected to the upper ends of the upper rails 160 with each cable fixedly attached to an upper end of the glideboard 210.
A user adjusts the incline of the rails 150, 160 to adjust the resistance level of the inclinable exercise device 100. To adjust the incline of the rails 150, 160, a user lifts the upper ends of the upper rails 160 so that rail hooks 230 at the upper ends of the upper rails 160 are disengaged from (i.e., lifted off of) the catches 140. The rails 150, 160 are then positioned at the desired level/incline relative to the vertical support members 130 and the rail hooks 230 at the upper ends of the upper rails 160 are placed onto the catches 140 to secure the upper ends of the upper rails 160 to the vertical support members 130.
The ab crunch board 110 will now be described in more detail. The ab crunch board 110 includes a handle bar 240 with two mirror-image brackets 250 welded to each side to create a frame 260. The handle bar 240 is substantially U-shaped with a central incurved hand grip portion 270. The handle bar 240 terminates in opposite terminating engagement portions 275. A pull pin barrel 280 is welded to each bracket 250 and is painted black with texture for grip. An upholstered padded board or support 290 is bolted to the frame 260. Pull pins 300 are screwed into the barrels 280.
The ab crunch board 110 is installed on either the upper rails 160 (FIG. 1), with the central incurved hand grip portion 270 facing upwards towards the tower 120 and adjacent the upper ends of the upper rails 160, or on the lower rails 150 (FIG. 2), with the central incurved hand grip portion 270 facing downwards towards the base tube 200 and adjacent the lower ends of the lower rails 150 for different exercises. To install the ab crunch board 110 onto the rails 150, 160, one side of the ab crunch board 110 is lowered onto the rail 150, 160 and causing the pull pin 280 to engage a mounting hole of the rail 150, 160. The opposite pull pin 280 is pulled outwardly and that side of the ab crunch board 110 is lowered on the corresponding rail 150, 160. This pull pin 280 is released so that it engages the mounting hole in the rail 150, 160. The ab crunch board 110 is secured to the rails 150, 160 with a lower surface of the opposite terminating engagement portions 275 resting on top of the rails 150, 160. In embodiments of the rails 150, 160 where the rails do not have mounting holes, the ab crunch board 110 includes socket mounts to mount the ab crunch board 110 to the rails 150, 160.
With reference to FIGS. 1 and 3, a method of exercising using the ab crunch board 110 installed near the upper ends of upper rails 160 will be described. With the cable(s) and handles removed from the inclinable exercise device 100, a user exercises one's abdominal and oblique muscles in calibrated loaded contractions depending on the level of incline of the rails 160, 160 with respect to the tower 120. A straight-on ab pull is performed by the user holding the handle bar 240 with one's hands and resting one's forearms on the padded board 290. The user then lies flat (downward facing) on the movable glideboard 210 and grips the handle bar 240 at the central incurved hand grip portion 270 or at another location of the handle bar 240. The user then crawls or walks one's lower body forward on the movable glideboard 210 so that the user is kneeling on the glideboard 210 with one's knees near the end of the glideboard 210 closest to the ab crunch board 110 as shown in FIG. 1. Using primarily one's abdominal muscles the user tries to pull one's knees into one's chest. This causes the glideboard to move forward so one's knees (with the glideboard 210) move under one's torso. In an exemplary method, this is performed with one's feet off the glideboard 210. This method of exercising one's abdominal muscles allows users to work almost their complete range of body motion at more or less resistance (i.e., by adjusting the incline of the rails 150, 160).
In another method of exercising using the ab crunch board 110, a user exercises one's obliques in a similar manner by kneeling on the glideboard 210, but with one's torso twisted to the side. The user grips the handle bar 240 at the central incurved hand grip portion 270 or at another location of the handle bar 240 (e.g., straight lateral sections of handle bar 24) with one's forearms rested on padded board 290 and pulls one's knees up towards one's chest again. Using primarily one's oblique muscles the user tries to pull one's knees into one's chest. This causes the glideboard 210 to move forward so one's knees (with the glideboard 210) move under one's torso. In an exemplary method, this is performed with one's feet off or partially off the side of the glideboard 210.
With reference to FIGS. 2 and 3, in a further method of exercising using the ab crunch board 110 a user works one's lower back and upper abdominal muscles in extension by exercising using the ab crunch board 110 installed near the lower end of the lower rails 150. To do this exercise, the user lies down on the glideboard 210 facing down and grasps the handle bar 240 at the central incurved hand grip portion 270 or at another location of the handle bar 240 (e.g., straight lateral sections of handle bar 24) with one's forearms rested on padded board 290. The glideboard 210 is then pushed up, away from the ab crunch board 110, and one crawls or walks one's knees or feet down the glideboard 210 until the glideboard 210 is as far away from one's arms as possible and one's body is substantially level with the rails 150, 160 as shown in FIG. 2. The user may lift one's feet off the glideboard 210 so that the user's knees support one's weight on the glideboard 210. Then the user pulls one's hips upwards, away from the rails 150, 160, as one allows the glideboard 210 to roll down the rails 150, 160 towards the ab crunch board 110. An advance version includes keeping one's legs straight so that one's feet support the user's weight on the glideboard 210 and the user lifts one's forearms off the padded board 290 so that the user only holds onto (and contacts) the handle bar 270.
The ab crunch board 110 in conjunction with the inclinable exercise device 100 allows a user to perform a wide variety of downward-facing crunch exercises to exercise one's abdominal muscles, oblique muscles, and lower back muscles with almost a complete range of body motion and at multiple different resistance levels.
