CROSS REFERENCE TO RELATED APPLICATIONS
 This application claims the benefit of U.S. Provisional Application No. 61/444,259, filed Feb. 18, 2011, which is hereby incorporated by reference.
 The present disclosure generally pertains to exercise apparatus, and more particularly, to exercise instability bars. Some examples of exercise bars according to the present disclosure may be used for fitness training to tone muscle and increase core strength.
 Exercise instability bars and systems are generally disclosed. Some example embodiments may include methods, apparatus, and/or systems associated with exercise attachments or instability bars.
 Example exercise apparatus include a rigid bar fixed to a sturdy frame, and optional removable resistance tubes or bands. The bar itself should be strong and rigid enough to support body weight to include body weight training such as pull-ups and pushups. A central attachment point at the center of the bar connects it to a sturdy frame. A plurality of off-center attachment points are located on the "bottom" of the bar, with respect to the central attachment point, which is located on the surface rotated by 180 degrees. The resistance bands are attachable, removable and interchangeable on these off-center attachment points.
 The off-center attachment points are distributed evenly on both sides of the center attachment point, and are symmetrical on either side of the center. An exemplary off-center attachment point configuration may be as follows. Two off-center attachment points may be set close to the middle of the bar. Midway between these off-center attachment points and the end of the bar are two more off-center attachment points. Finally, two off-center attachment points are located at the end of the bar to provide the least stabilization.
 Resistance bands or tubes may be attached to any one of the plurality of attachment points. The resistance bands have handles on one end. Generally, two resistance bands are attached to the bar--one on each side of the center, to accommodate the two sides of a user. In an exemplary embodiment, this band may be an elastic resistance band or tube, but it may also be another type of attachment, such as a cable band, or a strap.
 In an exemplary embodiment, a carabiner connects the resistance band to an attachment point. The bands have a small loop sewn on one end and a rubber handle sewn on the other. The end with the small loop loops onto the carabineer. The carabiner then fits onto an attachment point at the bottom of the bar. Other ways to connect the handle and strap to the bar include hooks, loops, or tabs on the bar.
 In an exemplary embodiment, the bar is formed from metal. Oval hole pairs are punched into the tube for attachment points. These holes can be any shape, but oval holes allow the connecting carabiner to move smoothly when the device is in use. The holes pairs are punched through the bar at the same length position on the bar. There are a total of fourteen holes. Two holes are located on the center top of the bar. These holes are for connecting the central attachment, to connect to a frame. On the opposite side of the bar are twelve holes for resistance band handle placement. There may be three pairs of evenly spaced holes on either side of the center. There can be any number of holes on the bar and these holes can be any shape and placed at any location in the tube to vary the stability and resistance.
 In an exemplary embodiment, the stability bar is plastic. Three pieces make up the bar including the center member, and the two identical partial bars that connect to the center member. The center member has a cutout at the top of the device to connect a strap. This strap attaches to a stable frame or structure. The center member contains female threading allowing the two partial bars to connect. Each partial bar has three molded loops. The holes in the loops allow a carabiner to fit through, which connects the resistance tubing. In an exemplary embodiment, there are a total of six loops and one center cutout on the plastic bar. The loops are evenly spaced over the length of the bar. The hole design, placement, and number of holes may vary and accomplish the same results in this disclosure.
 The size and shape of both the plastic and metal bar may vary. The length may vary, and the tubing may be circular, rectangular, or oval in cross-section. The bar may be straight or curved. Any number of holes may be placed at any location on the bar to attach carabineers or other attaching pieces. The center member of the plastic bar may attach in any way, not necessarily a screw.
 The center attachment piece connects the stability bar to a sturdy frame for exercise. In one use, the bar is connected by the center point to the frame, so it moves freely in any direction when the bar is pushed or pulled, and the user must exert force to stabilize it. The attachment points in the bar are located at various points to provide different torque during exercise. The wider the resistance bands or straps are attached, the more unstable the bar and the more effort is required by the user to stabilize the bar. When the bands are in place in the bar, the user will use the resistance for exercise, and force on the bands and straps control the movement of the bar. Additional work will be performed stabilizing the bar. In the absence of bands or straps, the bar may be used as a cable attachment or for body weight exercises.
 The exercise apparatus in the disclosure may be made by way of fabrication, machining, and injection molding. The straps and part of the center attachment piece may be fabricated, such as from nylon or polyester. The bands and handles may be injection molded. The resistance bands may be different sizes and resistance. The straps may be manufactured in various sizes and shapes. The bar, portions of the center attachment piece, and attachment pieces may be machined.
 A person could use the stability bar by attaching the center attachment piece to a stable frame. Then based on the desired exercise, the user would attach bands, straps, or cables to various attachment positions on the bar, or use the bar itself for pull-ups, push-ups, and other body weight exercises.

 The present disclosure pertains, inter alia, to exercise systems, such as stability bar systems. Some example embodiments according to the present disclosure may comprise a stability bar, which may include a substantially straight bar, attachments, and resistance bands.
 An exemplary embodiment of the stability bar system 100 is shown in FIG. 1. The stability bar system 100 includes an elongated bar 200, with a metal body 201. Metal ring 222 is coupled to the top of the bar 200 and connects strap 220 to the bar 200 at the attachment point 206 at the center of the bar. Strap 220 may have a body of nylon webbing 221 and an adjustable buckle 223. The metal ring 222 and strap 220 assembly may or may not be easily detachable from the center of the bar 200. The bar 200 has optional end-caps 203 and a plurality of attachment points 205 extending along the bottom of the bar 200. The plurality of attachment points 205 allow resistance bands 210, for example, to be attached and detached at various points on the bar 200. The resistance bands 210 have a band 212, and a handle 214 as well as a bearing cylinder 213 to allow the handle 214 to swivel.
 FIG. 2 depicts the plurality of attachment points 205 on the underside of a metal stability bar 200 with body 201. Each attachment point 205 along the body 201 comprises a hole pair, 205a and 205b extending through the bar 200 to provide a through-hole for one carabiner 223 to be inserted into and out of the bar 201. Similarly, hole pair 205c/205d through 205d/205l provide through-holes for a carabiner 223 to enter and exit the bar body 201 and lock into the bar 200.
 FIG. 3 is a perspective view of a metal stability bar 200, including a metal body 201 and end-caps 203. The plurality of attachment points 205 are oriented along one edge of the bar 201, while the central attachment point 206 is on an opposite edge. A carabiner 223 attaches into the central attachment point 206a/206b. The central attachment point 206a and 206b lie on the same length of the bar 200 so the bar is balanced on either side when it is attached to a frame 500.
 A second exemplary embodiment, as shown in FIG. 4, is a front view of a plastic stability bar system 101 including the bar 300, bar body 301, center member 322 and strap 320. The center member 322 engages the bars 301a and 301b together with a screw thread system. Strap system 320 is made from a nylon webbing or strip 319 and buckle 323 for latching onto a stable frame 500.
 FIG. 5 shows one side of the bar 301a, unscrewed and disassembled from the central cuff 322. The external screw threads 302 of the bar 301 are exposed, which in an in-use position is threaded into and locked into cuff 322 of FIG. 6a. Central cuff 322 keeps 301a and 301b locked and engaged in a rigid and stable position. Abutment head 325 prevents further turns and allows proper orientation of the tabs 305 to face downwards in relation to the cuff 322 and slit 323, which points in a radially opposed direction from the tabs 305.
 FIG. 6a shows an X-ray view of the central cuff 322 of the plastic stability bar system 101 depicting the internal female threading 303. FIG. 6b shows a perspective view of the center cuff 322 including the outside barrel 304, and axially extending cut-out 323 on the radial tab 321 for the strap 320.
 As shown in FIG. 7, stability bar system 100 may be attached to frame 500 by attachment point 222, and operated in a first orientation. The resistance band system 210 is hooked into a narrow, or stable position, into points 205e/205f, and 205g/205h. The user or person P is operating the stability bar system 100 in a first orientation, facing towards the stability bar system 100. P engages the triceps brachii and latissimus dorsi muscles, as well as the core by keeping the bar 200 stable, while exerting a force against the resistance created by the system 100.
 FIG. 8 shows a stability bar system 100 attached to a frame 500 at connection 222, and in use by P. The resistance band system 210 is in a wide, less stable position, on attachment points 205a/205b, and attachment points 205k/205l. The user P is facing away from the stability bar system 100 where the resistance is coming from, and thus P is engaging pectoral muscles to press away from the resistance. The core muscles are engaged to keep the bar 200 in a stable position.
