A distal end of the device has a minimal radius of curvature, such that the surface area of the device in contact with the ground is minimized, thereby inducing instability. The user is challenged to overcome the inherent instability of the push-up device, thereby recruiting more muscle groups, placing higher demand on involved muscle groups, and practicing balance and proprioception. Additionally, by elevating the user's hands above the ground, the device can also enable the user's chest to move below the plane of the palms of his or her hands, thus inducing a larger range of motion with each push-up and further challenging the user's muscles. ## Claims ### Claim 1 A push-up device for use on a surface for performing a push-up, the push-up device consisting essentially of: a single handle having a first end, said handle sized and configured to isometrically challenge the grip and forearm muscles of a user; and a support structure coupled to said first end at an acute angle, said support structure having a point opposite said first end, said point being sized and configured to remain in an initial location, wherein when in use the device makes contact with the surface through said point and at the initial location on the surface, wherein said point has a radius of curvature that induces instability when the device is in use, wherein said radius of curvature is such that said point has a hemispherical tip, wherein said support structure is a single cylindrical rod member extending from said first end to said single point and has a length such that, when the push-up device is in use, the cylindrical rod member raises said handle above the surface by greater than 4 inches and less than 18 inches, and wherein the device is configured for performing a push-up and said handle is configured to be parallel to the surface when a user is performing a push-up. ### Claim 2 (depends on 1) A push-up device according to claim 1, wherein said handle is cylindrical. ### Claim 3 (depends on 2) A push-up device according to claim 2, wherein said handle has a diameter of greater than 1 inch and less than 3 inches. ### Claim 4 (depends on 2) A push-up device according to claim 2, wherein said handle has a diameter of greater than 1 inch. ### Claim 5 (depends on 1) A push-up device according to claim 1, wherein said handle has a shape that conforms to a user's hand and fingers. ### Claim 6 (depends on 1) A push-up device according to claim 1, wherein said radius of curvature is ¼ inch. ### Claim 7 (depends on 1) A push-up device according to claim 1, wherein said handle and said support structure are a unitary body. ### Claim 8 (depends on 7) A push-up device according to claim 7, wherein said support structure has an upper end opposite said point, wherein said handle is cylindrical, and wherein said upper end has a diameter equal to a diameter of said handle. ### Claim 9 A push-up device for use on a surface for performing a push-up, the push-up device consisting essentially of: a single handle having a first end, said handle sized and configured to isometrically challenge the grip and forearm muscles of a user, wherein said handle is cylindrical and has a diameter; and a support structure having a second end attached to said first end of said handle at an acute angle and a point opposite said second end, said point including a hemispherical tip and configured to remain in an initial position on the surface when in use, wherein said support structure is a single cylindrical rod member extending from said first end to said single point and has a length such that, when the push-up device is in use, the cylindrical rod member raises said handle above the surface by greater than 4 inches and less than 18 inches; wherein the device is configured for challenging a user performing a push-up, wherein said point has a radius of curvature that induces instability, and wherein said second end has an end diameter that is equal to said diameter of said handle, and wherein said handle is configured to be parallel to the surface when a user is performing a push-up. ### Claim 10 (depends on 9) A push-up device according to claim 9, wherein the diameter of said handle is greater than 1 inch and less than 3 inches. ### Claim 11 (depends on 9) A push-up device according to claim 9, wherein said handle conforms to a user's hand and fingers. ### Claim 12 (depends on 9) A push-up device according to claim 9, wherein said radius of curvature is ¼ inch. ### Claim 13 (depends on 9) A push-up device according to claim 9, wherein said handle and said support structure are a unitary body. ### Claim 14 A push-up device for performing a push-up on a surface, the push-up device comprising: a handle having a first end, said handle sized and configured to isometrically challenge the grip and forearm muscles of a user; a support structure coupled to said first end, said support structure having a point opposite said first end, wherein said support structure is a cylindrical rod member extending from said first end to said single point and has a length such that, when the push-up device is in use, the cylindrical rod member raises said handle above the surface by greater than 4 inches and less than 18 inches; and a dispersion device with a flat bottom end and a top end, said top end including a divot for receiving said point and said bottom end contacting the surface when the push-up device is in use, wherein, when in use, said point can freely rotate within said divot without translating horizontally, wherein said point has a radius of curvature that induces instability when the push-up device is in use, and wherein the push-up device is configured for performing a push-up.
