A lower back exercise apparatus exercises or imparts laterally and upwardly directed movements into a user's lower back when seated thereupon. The lower back exercise apparatus includes a lower base assembly, an upper seat assembly, and a motor assembly. The lower base assembly includes an upper, laterally concave base surface. The upper seat assembly includes a lower, laterally convex seat surface and an upper seat surface. The upper seat assembly is laterally ridable upon and movable relative to the lower base assembly. The motor assembly is drives a laterally directed, cylindrical arc length trajectory of the upper seat assembly relative to the lower base assembly. The concave and convex surfacing have a common radius of curvature with a common fulcrum point spatially located adjacent an upper portion of a user's lumbar spinal region. Lateral flexion is thus imparted into a user's lower back when a user is seated thereupon.

An exercise device that exercises both flexor and extensor muscles. The exercise device includes a base. First and second sidewalls upwardly extend from opposing sides of the base. Each of the first and second sidewall has a plurality of teeth formed on an upper rim extending from the front end to the rear end of the base. At least a first gear is secured to a first end of an elongated rod and at least a second gear is secured to a second end of the elongated rod. A plurality of teeth of the first gear interlock with the plurality of teeth of the first sidewall and a plurality of teeth of the second gear interlock with the plurality of teeth of the second sidewall. A board rests on the elongated rod in between the first end and the second end.

A curved manual treadmill for the physical exercises of a user, comprising: a frame extending along a longitudinal direction; a first rotation shaft adapted to rotate around a respective first rotation axis transversal to the longitudinal direction of the frame; a second rotation shaft adapted to rotate around a respective second rotation axis transversal to the longitudinal direction of the frame; a physical exercise surface operatively connected to the first rotation shaft and to the second rotation shaft, so as to generate an endless closed physical exercise path, and a device for resisting the movement of the upper portion of the physical exercise surface operatively associated with at least either the first rotation shaft or the second rotation shaft.

A treadmill includes a frame having a front end and a rear end, substantially opposite the front end; a front shaft assembly coupled to the frame proximate the front end of the frame; a rear shaft assembly coupled to the frame proximate the rear end of the frame; a running belt disposed about the front and rear shaft assemblies; and a bumper coupled to the frame proximate the running belt such that the bumper is disposed between the running belt and the frame. In use, the bumper is configured to selectively restrict movement of the running belt towards at least a portion of the frame.

A manually powered treadmill includes a front rotatable element and a rear rotatable element coupled to a frame; a bearing assembly at least partially supporting one of the front or rear rotatable elements; and a running belt disposed about the front and rear rotatable elements. The bearing assembly includes a predefined low viscosity bearing fluid. The running belt defines a non-planar running surface. The running belt includes a first endless belt and a plurality of slats, each slat having a first side and a second side and coupled to the first endless belt. Each slat in the plurality of slats defines at least one aperture, and the at least one aperture is structured to receive a fastener to facilitate coupling to the first endless belt.

A device for training and rehabilitation of a limb is provided. The device provides a board with an ability to magnetically levitate a movement base above the board to allow for controlled movement of a limb or other body part of a user needing training and rehabilitation in various directions.

The present invention relates to a novel exercise equipment for simulation of ski routines, with a resistance regulation mechanism, with individual resistance elements

An upper and lower body reciprocating arcing motion exercise machine with an adjustable angle user support frame, left and right lower body user support assemblies having foot platforms and shin support pads mounted on an arcing track for movement along rearward and central portions of the user support frame, and left and right upper body user supports having gripping handles mounted on pivotable levers that move in an arcing motion relative to a forward and central portion of the movable user support frame. A linkage assembly operatively connects and synchronizes the exercise motions of the upper and lower body user support assemblies. In certain embodiments, an adjustable resistance mechanism is operatively engaged with the upper and lower body user supports for providing adjustable resistance to the exercise motion of the upper and lower body user supports.

A crawling simulation exercise and stretching machine having left and right horizontally oriented curved tracks suspended between a forward support frame and a rearward support frame, left and right leg supports assemblies movably mounted on the curved tracks and each having a foot platform and shin pads for supporting a user's legs, left and right arm supports assemblies pivotally mounted on the front support frame and each having a lever and handle for supporting a user's arms, a rocker arm assembly located central to the leg supports assemblies and the arm supports assemblies, and multiple linkage assemblies operably connecting the leg supports assemblies and the arm supports assemblies to the rocker arm assembly such that the leg supports assemblies and the arm supports assemblies cooperate to create a reciprocating arcing motion of a user's arms and legs to simulate a crawling exercise or stretching motion.

An exercise device focusing on core strengthening and development of abdominal and gluteal muscle groups provides a curved inner track which provides a rolling seat and a flat outer track providing a rolling leg support over which the legs engage, positioning the body in a recumbent position, with contraction and extension of the abdomen compelling the rolling seat and rolling leg support using a pelvic thrusting motion to strengthen and exercise lower back, abdominal, gluteal, quadriceps and hamstring muscles and to improve and refine the shape and condition of the muscle groups.
