## Background
CROSS-REFERENCE TO RELATED APPLICATIONS
The present application claims priority to, incorporates herein by reference, and is a non-provisional of U.S. provisional patent application Ser. No. 62/150,040 filed Apr. 20, 2015 and entitled Exercising Implements and Methods of Use for Performing Muscular Stretching Exercises, Respiration Exercises, and Resistance Training (herein, “the '040 application”).


FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT
None.
TECHNICAL FIELD
The present invention relates generally to exercising implements and methods of use for performing muscular stretching exercises, respiration exercises, and resistance training, including in certain example embodiments articulating benches configured to support a user.
BACKGROUND
Benches configured to support a user lying thereon are known. For example, a bench sold under the trademark Pancafit® has been sold in Italy, and is described in materials that were filed as part of the '040 application and thus form part of this application, including an English language copy of European patent specification EP 0999880 B1 (herein collectively, the “Pancafit® product”). Various drawbacks or limitations have been noted with the Pancafit® product, including that the body supporting surfaces sit almost directly on the floor, making it difficult or uncomfortable for some users to get on and off. It has also been noted that the Pancafit® product may be too weak, flimsy, and narrow for some users, especially for resistance training. It has further been observed that the mechanisms that allow portions of the Pancafit® product to pivot tend to stick instead of moving smoothly, and can be difficult and non-intuitive to understand how to use. Further, the Pancafit® product does not provide a surface to support a user's arms, but rather provides extendable handles for the user to grab with their hands. Moreover, a user of the Pancafit® product has to reach back behind her or his shoulders to grab the extendable handles, which can be uncomfortable or impossible for someone with an injury.
SUMMARY
The present invention(s) elegantly overcome many of the drawbacks of prior systems and provide numerous additional improvements and benefits as will be apparent to persons of skill in the art. Provided in various example embodiments are strong, easy and intuitive to use, articulating benches configured to better support a user in more potential positions while performing muscular stretching exercises, respiration exercises, and resistance training, all while having the capability to simultaneously help the user achieve parasympathetic activation. The bench's adjustable “V” angle, along with the separately pivotable support surfaces for each leg and separately-pivotable arm support surfaces, contribute to the superior sensation of three-dimensional or multi-planar support. Used in a variety of positions and postures, devices made according to various example embodiments can directly impact and positively influence joints, releasing chronically held muscle tension and facilitating helpful postures to get the user's body to naturally shift away from a sympathetic state (active, catabolic) and instead engage the parasympathetic nervous system (regenerative, anabolic). Essentially, the device can help the user relax by relieving areas of chronic physical stress, while simultaneously supporting the user's body during muscular stretching exercises, respiration exercises, and resistance training.

Also shown in FIGS. 1, 4, and 5 are example removably-attached (for instance with fasteners, not shown) left and right arm supporting portions, 400, 500, respectively, positioned at various example angles with respect to the back supporting portion 100, according to various example embodiments.
FIG. 7 is a left side elevation view of the example articulating bench of FIG. 1 showing the back supporting portion 100 and the left and right leg supporting portions 200, 300 at the angles shown in FIG. 6. Provided in various example embodiments is a frame structure 600 extending longitudinally about a first longitudinal axis (i.e., any line extending horizontally left to right across FIG. 7), the frame structure 600 sized, shaped, and constructed to support a back supporting portion 100 and left and right leg supporting portions 200, 300 and the user 2000 lying thereon, for instance as shown in FIG. 11. In various example embodiments the user may weigh up to 300 pounds, or more in various examples. The frame structure may comprise a centrally-located central portion 700 to which the back supporting portion 100 and the left and right leg supporting portions 200, 300 are pivotably attached, as shown in the Figures. The frame structure may further comprise a back support frame structure 900 pivotably attached with the central portion 700 and a leg support frame structure 800 pivotably attached with the central portion 700. As illustrated in FIG. 9, the frame structure 600 may be constructed to fold-up about the central portion 700 by the back support frame structure 900 and the leg support frame structure 800 both independently pivoting about the central portion 700 from about zero degrees when the back support frame structure 900 and the leg support frame structure 800 are approximately horizontal (as shown in FIGS. 1-7), up to approximately 90 degrees when the back support frame structure 900 and the leg support frame structure 800 are approximately vertical, as depicted in FIG. 9. This option provides for compact storage of the articulating bench 1000, which can be readily unfolded to the position shown in FIGS. 1-7. The frame structure 600 may be formed from any suitable material, such as, for example, steel or aluminum, in tubular, extruded, cast, or other suitable form, and may be assembled from many individual pieces or may be manufactured as one unitary structure or an assembly of unitary sub-structures.
With continuing reference to FIGS. 1-7, the back supporting 100 portion may be pivotably attached with the frame structure 600 about a first horizontal axis 110 perpendicular to the first longitudinal axis (i.e., in FIG. 7 the first horizontal axis 110 would extend perpendicularly out of the page). The first horizontal axis 110 may comprise a pivotable joint located on a central portion 700 of the frame 600. The back supporting portion 100 may be fixable at a first range of angles with respect to the frame structure 600, for example as depicted in FIGS. 2, 3, and 7. In various example embodiments the first range of angles may range from about zero degrees when the back supporting portion 100 is horizontal as shown in FIG. 2, up to at least 45 degrees, 60 degrees, 75 degrees, or any other suitable angle. The back supporting portion 100 may be sized, shaped, and constructed to extend underneath the entire length of and support the back 2100 and head of the user 2000 when the user 200 is lying on the articulating bench 1000, for instance as shown in FIG. 11. In one example embodiment the back supporting portion 100 may be formed in the shape of a rectangle about 42 inches long by about 17 inches wide with one-inch radius corners, and is constructed of wood about 3⁄8 of an inch thick. However, any suitable dimensions may be used. The back supporting portion 100 may be constructed from any suitable material, such as wood, metal, plastic, or composite material, may be covered in upholstery or padding (not shown), and may alternatively be constructed of fabric stretched over a perimeter frame (not shown).
The left leg supporting portion 200 may be pivotably attached with the frame structure 600 about a second horizontal axis 210 perpendicular to the first longitudinal axis (i.e., in FIG. 7 the second horizontal axis 210 would extend perpendicularly out of the page). The second horizontal axis 210 may comprise a pivotable joint located on a central portion 700 of the frame 600. The left leg supporting portion 200 may be fixable at a second range of angles with respect to the frame structure 600, for example as depicted in FIGS. 1 through 4. In various example embodiments the second range of angles may range from about zero degrees when the left leg supporting portion 200 is horizontal as shown in FIG. 2, up to at least 45 degrees, 60 degrees, 75 degrees, or any other suitable angle. The left leg supporting portion 200 may be sized, shaped, constructed, and located to extend underneath the entire length of and support the user's left leg 2200 and left foot when the user 2000 is lying on the articulating bench 1000, for instance as shown in FIG. 11. In one example embodiment the left leg supporting portion 200 may be formed in the shape of a rectangle about 42 inches long by about 8.25 inches wide with one-inch radius corners, and is constructed of wood about 3⁄8 of an inch thick. However, any suitable dimensions may be used. The left leg supporting portion 200 may be constructed from any suitable material, such as wood, metal, plastic, or composite material, may be covered in upholstery or padding (not shown), and may alternatively be constructed of fabric stretched over a perimeter frame (not shown).
The right leg supporting portion 300 may be pivotably attached with the frame structure 600 about the same second horizontal axis 210 as the left leg supporting portion 200, and may likewise comprise a pivotable joint located on a central portion 700 of the frame 600. While in the example embodiment shown in the Figures the first and second horizontal axes 110, 210 are separated longitudinally on the central portion 700 of the frame structure 600 and thus are not coaxial, in other example embodiments the first and second horizontal axes 110, 210 may be the same axis and thus coaxial, for instance as depicted in certain embodiments in the '040 application. The right leg supporting portion 300 may be fixable at a third range of angles with respect to the frame structure 600, for example as depicted in FIGS. 1 through 4, and may be movable independently of the left leg supporting portion 200, as depicted in the Figures. In various example embodiments the third range of angles may range from about zero degrees when the right leg supporting portion 300 is horizontal as shown in FIG. 2, up to at least 45 degrees, 60 degrees, 75 degrees, or any other suitable angle. The right leg supporting portion 300 may be sized, shaped, constructed, and located to extend underneath the entire length of and support the user's right leg 2300 and right foot when the user 2000 is lying on the articulating bench 1000, for instance as shown in FIG. 11. In one example embodiment the right leg supporting portion 300 may be formed in the shape of a rectangle about 42 inches long by about 8.25 inches wide with one-inch radius corners, and is constructed of wood about 3⁄8 of an inch thick. However, any suitable dimensions may be used. The right leg supporting portion 300 may be constructed from any suitable material, such as wood, metal, plastic, or composite material, may be covered in upholstery or padding (not shown), and may alternatively be constructed of fabric stretched over a perimeter frame (not shown).
Also provided in various example embodiments is a left arm supporting portion 400 pivotably attached with the back supporting portion 100 about a second longitudinal axis 410 (FIG. 9) perpendicular to the first horizontal axis 110.

The left arm supporting portion 400 may be fixable at a fourth range of angles with respect to the back supporting portion 100, for example as depicted in FIGS. 1, 4, and 5. Any suitable mechanism for fixing the location of the left arm supporting portion 400 with respect to the back supporting portion 100 may be used, such as a locking pivot joint, or any of the structures shown in the Figures, including as shown in the '040 application. In various example embodiments the fourth range of angles can range from at least about negative 90 degrees when the left arm supporting portion 400 is positioned approximately vertically downward relative to the back supporting portion 100 (not shown), up to at least about positive 90 degrees when the left arm supporting portion 400 is positioned approximately vertically upward relative to the back supporting portion 100 (for instance as shown with respect to the right arm supporting portion 500 as positioned in FIG. 4). The left arm supporting portion 400 may be sized, shaped, constructed, and located to extend underneath and support at least an upper portion 2400 of the user's left arm when the user 2000 is lying on the articulating bench 1000, for instance as shown in FIG. 11. In one example embodiment the left arm supporting portion 400 may be formed in the shape of a right trapezoid about 30 inches long by about 9 inches wide at the bottom increasing to about 16 inches wide at the top, with one-inch radius inner corners and two-inch radius outer corners, and is constructed of wood about 3⁄8 of an inch thick. However, any suitable dimensions may be used. The left arm supporting portion 400 may be constructed from any suitable material, such as wood, metal, plastic, or composite material, may be covered in upholstery or padding (not shown), and may alternatively be constructed of fabric stretched over a perimeter frame (not shown).
Further provided in various example embodiments is a right arm supporting portion 500 pivotably attached with the back supporting portion 100 about a third longitudinal axis (parallel to 410 in FIG. 9, but on the opposite side of the back supporting portion 100), which like second longitudinal axis 410 is perpendicular to the first horizontal axis 110. The right arm supporting portion 500 may also be removably attached with the back supporting portion 100 via bracketry 520 (FIGS. 8A, 8B). The right arm supporting portion 500 may be fixable at a fifth range of angles with respect to the back supporting portion 100, for example as depicted in FIGS. 1, 4, and 5. Any suitable mechanism for fixing the location of the right arm supporting portion 500 with respect to the back supporting portion 100 may be used, such as a locking pivot joint, or any of the structures shown in the Figures, including as shown in the '040 application. In various example embodiments the fifth range of angles can range from at least about negative 90 degrees when the right arm supporting portion 500 is positioned approximately vertically downward relative to the back supporting portion 100 (not shown), up to at least about positive 90 degrees when the right arm supporting portion 500 is positioned approximately vertically upward relative to the back supporting portion 100 (for instance as shown in FIG. 4). The right arm supporting portion 500 may be sized, shaped, constructed, and located to extend underneath and support at least an upper portion 2500 of the user's right arm when the user 2000 is lying on the articulating bench 1000, for instance as shown in FIG. 11. In one example embodiment the right arm supporting portion 500 may be formed in the shape of a right trapezoid about 30 inches long by about 9 inches wide at the bottom increasing to about 16 inches wide at the top, with one-inch radius inner corners and two-inch radius outer corners, and is constructed of wood about 3⁄8 of an inch thick. However, any suitable dimensions may be used. The right arm supporting portion 500 may be constructed from any suitable material, such as wood, metal, plastic, or composite material, may be covered in upholstery or padding (not shown), and may alternatively be constructed of fabric stretched over a perimeter frame (not shown).
In various example embodiments, the back supporting portion 100 and the left leg supporting portion 200 and the right leg supporting portion 300 are all approximately coplanar when all of said portions are in approximately horizontal positions, for instance as shown in FIG. 2. Where a left arm supporting portion 400 and a right arm supporting portion 500 are provided, the back supporting portion 100, the left leg supporting portion 200, the right leg supporting portion 300, the left arm supporting portion 400, and the right arm supporting portion 500 are all approximately coplanar when all of said portions are in approximately horizontal positions (not shown but understood in view of FIGS. 1 and 2).
