Abstract: A exercise device, for example, and exercise ball device. The exercise device includes a frame and at least one panel or multiple panels.

Abstract: A mobility tool includes a body having first and second opposed ends and an outer surface, and a connection structure at the first end of the body, where the connection structure is configured for connection to a mounting structure. The outer surface of the body includes a top surface, a bottom surface, and side surfaces extending between the first and second ends, where the top and bottom surfaces have greater surface area than the side surfaces. The bottom surface has a contour that includes a convex portion proximate the first end and a concave portion proximate the second end. The height of the body is greater at the convex portion than the concave portion and smallest at the second end. The body further includes an inner body formed of a rigid material, and an outer body at least partially covering the inner body and formed of a flexible material having greater flexibility than the rigid material.

Abstract: An exercise bike includes a frame, a rotor assembly and a drive assembly mounted on the frame, where the drive assembly is configured to drive rotation of the rotor assembly, and a cover configured to at least partially cover the rotor assembly. The components of the drive assembly and the rotor assembly include structures that improve the performance of the exercise bike, including but not limited to a strong and rigid construction and improvements in belt tracking, user feel, effort consistency, synchronization, and rotor performance.

Abstract: A bone plate having at least one variable angle locking hole is described. The variable angle locking hole allows a bone anchor having a threaded head to be driven into underlying bone while oriented at an angle with respect to a central hole axis of the hole that is within a range of angles at which the head is configured to threadedly mate with the at least one thread of the bone plate. Accordingly, the bone anchor can be driven into the underlying bone until the threaded head threadedly purchases with the bone plate inside the variable angle locking hole.

Abstract: An improved jump rope handle and method of assembling the same. The jump rope handle includes a head. The head includes a channel, a set hole perpendicular to the channel, and a set mechanism adjustably insertable into the set hole. The jump rope handle further includes a grip. The grip includes a cylindrical member, first and second bearings arranged along the cylindrical member, an inner bushing arranged along the cylindrical member between the first and second bearings, and a sleeve around said inner bushing, said bushing being fixedly attached to an inner surface of the grip. An end portion of the cylindrical member is fixedly attached to the head whereby the cylindrical member and the head rotate together about a same axis. The channel of the head is configured to receive a rope. The set mechanism is configured to be inserted into the set hole to secure the rope.

Abstract: A exercise roller device including a center roller portion provided with shaped end roller portions, and the center roller portion provided with a centered circumferential groove. A method of making the exercise roller device.

Abstract: A exercise ball device can include a ball and one or more panels supported by the ball. The ball can be substantially rigid and the at least one panel can be soft or resiliently deformable. The exercise ball can include a belt for guiding and positioning the one or more panels on the ball.
