Described herein are methods of manufacturing multi-use mounting brackets having an extension with an internal support rod configured to support gym accessories. A single multi-use mounting bracket fits gym rigging or gym racks of different sizes and hole configurations. This accomplished by including multiple pairs of holes that are sized and positioned to be compatible with different gym rigging configurations. The multi-use mounting brackets described herein are advantageously designed to resist both downward and upward forces.

A rowing machine has a base, a seat, a rotating plate, two oar components, a damping mechanism and a transmission mechanism; the base with a rack and a slope rail; the seat cushion slidably coupled to the rail; the rotating plate with a fixing rotating shaft rotatably assembled to the rack through the rotating shaft; two oar components respectively connected to the two ends of the rotating shaft by unilateral bearings in universal joining way to unilaterally drive the rotating plate to rotate when swinging; the rotation damping mechanism is assembled to the rack; the transmission mechanism assembled between the rotating plate and the damping mechanism to drive a damping wheel of the damping mechanism when the rotating plate rotates.

A portable therapeutic device includes a portable body having a recessed central region and a raised outer peripheral edge surrounding the recessed central region and directly engaged with the recessed central region, a plurality of massage balls seated at the recessed central region and spaced inside a perimeter of the raised outer peripheral edge, a thermal-conductive element channeled inside the outer peripheral edge and spaced from the recessed central region, and a power source communicatively coupled to the massage balls and the thermal-conductive element.

A sturdy portable massage roller that collapses flat. The roller includes an outer contact skin formed of a plurality of longitudinal stiffeners connected by longitudinally-extending hinge points, the contact skin defining an inner cavity. A collapsible support structure within the contact skin inner cavity is sized to contact and radially support the longitudinal stiffeners in the expanded shape of the contact skin, and is adapted to collapse so that the massage roller converts between a generally cylindrical expanded shape and a collapsed, flattened shape. The support structure may include a series of rigid discs that either pivot or are folded in half to convert the massage roller between its expanded and flat configurations.

A spine alignment and massage device with a rigid member have an elliptically shaped top plan view and a left and a right protrusion. The raised protrusions are mirror images of each other. The inside surface of each the protrusion is approximately eighty-four degrees in angle forming a V shaped space between the two protrusions. The outside surface of each protrusion slops down at approximately forty-five degrees. The distance between the top of the two protrusions are approximately one and three quarters of an inch. The height of each protrusion is approximately two inches. The top portion of each the protrusion is a hemisphere of approximately one half of one inch in diameter. The base portion of the rigid member is curved along the short axis and has a radius of approximately twelve inches. In an alternate embodiment, the device is made of semi-rigid material.

A treadmill having a curved treadmill deck is provided. Two curved side frames are disposed at two sides of the treadmill frame. Front and rear end ends of each curved side frame are higher than a middle section thereof. Inner sides of the two curved side frames are provided with a plurality of fixing seats, respectively. The fixing seats have fixing holes, respectively. An elastic deck is composed of a plurality of sheets connected side by side. The sheets each have perforations corresponding in position to the fixing holes of the respective fixing seats. A plurality of fixing pins are inserted in the perforations of the sheets of the elastic deck and secured to the fixing holes of the fixing seats. The elastic deck is forcibly fastened by the fixing pins and slightly deformed according to the curvature of the curved side frames to form the curved treadmill deck.

A unit has been designed to be applied within the area of physiotherapy and is applicable to both medical and athletic therapeutic programs to provide correction of functional states of the spine and the nervous system to eliminate nervous overloads, fatigue, and stress. Moreover, the unit corrects spinal disorders, paravertebral muscular disorders and can be used as a part of mobilizing procedures to act on biologically active body points, and as a part of therapeutic procedures to relieve the spine.

A foot therapy device comprises a generally hemispherical dome element detachably connected to a support element having substantially planar top and bottom faces. In some embodiments, the support element is optionally detachably connected to one or more additional stacked support elements.

An upper limb exercise apparatus comprises a base, a frame, and a display mounted on the frame. The apparatus further comprises 5-bar linkage-type movable parts positioned on the display and including a first link and a second link. The first link comprises a 1-1 member having one end attached to the frame and being rotationally driven, and a 1-2 member having one end rotatably attached to the other end of the 1-1 member, the other end having attached thereto a handle for gripping. The second link comprises a 2-1 member having one end attached to the frame and being rotationally driven, and a 2-2 member having one end rotatably attached to the other end of the 2-1 member, the other end having attached thereto the handle and the other end of the 1-2 member. Series elastic actuators attached to the 1-1 member and the 2-1 member provide torque.

A reduced friction massage and exercise device, which includes a base frame and at least one anchoring arrangement for anchoring a first body part of a user. A reduced friction surface is mounted onto the base frame, and includes a plurality of ball transfer units arranged such that adjacent ball transfer units engage one another. The device further includes at least one cable column including a weight stack. Each of the motion transfer balls is adapted for omnidirectional rotation relative to a corresponding housing element and independently of other the motion transfer balls. The reduced friction surface is adapted to have a second body part of the user placed thereon during performing of a physical activity applying force to the second body part, while reducing friction between the second body part and the surface.
