A leg movement stimulator device for use while sitting. Other embodiments of leg movement stimulator device include leg gliding mechanism (12) to allow simple exercise for user while simultaneously performing other sedentary activities, and extension function (13) for width adjustment, and a diversified movement mechanism (22), (22a) for joints and small muscles stimulation, and data generating and communicating mechanism (30), (30a), (31), (33) with user's smart electronic devices is also available for user's convenience in tracking and monitoring the movement activities. Other embodiments include chair fixing mechanism (14), (14a) to hold the device from moving, and stepper mechanism (11a), (11b), (22a), (22b) and varied track direction (12c) for diverse exercise of the user.

A ski exercising apparatus has a set of two parallel, arcuate rails, a wheeled carriage riding on the rails, a set of two articulated footpads mounted side-by-side on the wheeled carriage; and two sets of powerbands arranged parallel with a lengthwise centerline of the apparatus, spaced apart by at least one-half of the width of the apparatus.

An exercise device comprising: a frame having a generally vertical planar axis, first and second foot supports suspended on the frame by first and second linkage assemblies that are respectively arranged on the frame such that the first and second foot supports are pivotable through a front to back arcuate path of travel that is disposed at a selected angle between about five and about forty five degrees relative to the vertical planar axis.

An exercise machine comprising a resistance mechanism, a supporting frame, and a movable member which is movable relative to the supporting frame into and between a rest position and an extended position during performance of an exercise motion by a user. Movement of the movable member towards the extended position is resisted by the resistance mechanism. A stop device stops the movable member in the rest position, the stop device having an engagement member which engages and is able to translate along a stop surface on the supporting frame when the movable member is moved into the rest position.

A fitness apparatus includes a support assembly having a framework selectively mounted to one of a ground surface, building structure, or fitness apparatus. A foot assembly is rotatably coupled to the support assembly and configured such that the foot assembly is displaced above a ground surface. The foot assembly includes a pair of retention members configured to selectively support the feet of a person in a toes-pointed downwardly position and above the ground surface. The fitness apparatus that increases core muscle group activation by making traditional exercises more challenging. It is designed to have the user place their feet in a platform which then allows for three axis of rotation. Height adjustment gives the user more resistance. The largest benefit is that the user can perform these exercises without having to stop to re-adjust their feet.

A curved treadmill has a frame assembly, a handrail assembly, and a belt assembly. The frame assembly has a support frame, two arced guide tracks, two cushions, multiple guide wheels, and multiple positioning wheels. Each arced guide track is concaved downward. The cushions are mounted on the arced guide tracks. The guide wheels are mounted on the support frame. The positioning wheels are mounted between two ends of the support frame. The belt assembly includes two connection belts and multiple pedals. The connection belts are wrapped around the guide wheels, and one side of each connection belt abuts the positioning wheels. The pedals are mounted on the connection belts and optionally abut the cushions. Therefore, with the cushions, impacts may be absorbed and noises may be reduced. Besides, by abutting the positioning wheels, the connection belt may not be distorted sideward, and the noises are reduced further.

An arm rehabilitation system for exercising a user's arm. The system provides an arm support device moveable upon a support surface by a user's first arm. The arm support device has a main body configured to movably engage the support surface on one side and has a hand support portion on an opposing side at or toward one end of the body for supporting a user's hand of the first arm. A primary hand support formation protrudes from the hand support portion and a secondary hand support handle extends from the main body at or toward the periphery of the hand support portion. An adjustable switch support boom assembly is also mounted to the main body and has at least one operable user input component for generating an actuation signal in response to operation by the user. An onboard motion tracking system mounted to or within the main body is configured to sense motion of the main body to enable user interaction with an interactive computer system running an application program.

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 chair that is operable to engage a user's core muscle groups in order to maintain a desired position thereof. The exercise chair includes a base having a plurality of legs. A seat member is rotatably secured to the base. A first mounting plate is secured to the bottom of the seat member. A second mounting plate is secured to the first mounting plate. The second mounting plate is ring-shaped and undulated in form having at least two peak section and at least two valley sections. A wheel assembly is superposed the base and includes wheels configured to engage the second mounting plate and traverse therealong. A mount having a shaft coupled thereto rotatably couples the seat member with the base. In a first position of the exercise chair, the wheels of the wheel assembly are engaged with the at least two peak sections.
