A knee rehabilitation system includes a plurality of compressible resistance members, a knee garment, and a resistance member receptacle. Each compressible resistance member in the plurality of compressible resistance members has (i) a same size and a shape as each other compressible resistance member in the plurality of compressible resistance members, and (ii) a compression resistance different from each other compressible resistance member in the plurality of compressible resistance members. The knee garment has a knee garment ventral portion and a knee garment dorsal portion. The resistance member receptacle is coupled to the knee garment dorsal portion, and the resistance member receptacle is sized to carry each compressible resistance member in the plurality of compressible resistance members, one at a time.

There is disclosed a system for engaging in exercise. The system includes a removable resistance device suitable for temporary installation into multiple, separate exercise devices. When installed in the separate exercise device, the resistance device is operable under control of a computing device to selectively increase or decrease resistance applied to the separate exercise device and to thereby selectively increase or decrease the difficulty of an exercise associated with the separate exercise device.

In one example, an exercise apparatus comprises: a shaft; a roller wheel mounted on and rotatable around the shaft; a first pair of gripping members formed on two opposite ends of the shaft; a second pair of gripping members, each of the second pair of gripping members being formed on the shaft between one of the first pair of gripping members and the roller wheel; and a wall-mounting device connected to the shaft, the wall-mounting device being configured to be mounted on a wall above a top portion of a door frame to suspend the second pair of gripping members and the roller wheel in a space below the top portion of the door frame while the first pair of gripping members is in contact with two side portions of the door frame.

An exercise system includes a handle having a shaft, a head, a spindle, and a loop. The shaft extends from a first end to a second end. The head has a top, a bottom, a front, and a rear, the top opposite the bottom, the front opposite the rear, the bottom of the head affixed to the second end of the shaft. The spindle has a ring and is positioned at the front of the head with the spindle rotatably supported upon the head. The loop is affixed to the top of the head. The exercise system includes one or more elastic exercise cords configured to selectively connect to the loop or the ring. The exercise system may include one or more kettleballs configured to selectively connect to the one or more elastic exercise cords. The kettleballs and/or elastic exercise cords may be moved in a circular motion.

A weight rack system, comprising: at least one upright component provided with at least one cut-out on a front of the at least one upright, wherein the upright component is formed from a single sheet and is of unitary construction.

The invention herein relates to a variable weight exercise machine comprising a motor driven carriage assembly that moves along a linear path creating a variable resistant force against which the user exerts an opposite force. The chassis body and frame of said device may be positioned horizontally or vertically, and having a design that can be modularly configured in coordination with accessory elements to achieve a variety of concentric or eccentric exercise movements.

Methods, systems, and computer readable media for analyzing robotic physical rehabilitation systems. In some examples, a method includes receiving user interaction data characterizing a user's interaction with a robotic rehabilitation system. The robotic rehabilitation system includes one or more robotic motion machines, a control system for controlling motors of the robotic motion machines, and one or more sensors for collecting the user interaction data while the user performs physical rehabilitation training using the one or more robotic motion machines. The method includes analyzing the user interaction data to track the user's past course of treatment and determine an action for the user's future course of treatment. The method includes sending one or more commands to the control system of the robotic rehabilitation system based on the action for the user's future course of treatment.

An adjustable exercise machine for performing resistance exercises comprises a base and an upper frame including front and back end stationary exercise platforms, and a movable exercise platform that reciprocates between the stationary platforms. A plurality of biasing members is selectable by an exerciser via selector knobs to generate a bias force against the movable platform. A plurality of pivotable lift supports are connected between the base and the upper frame. Front and back actuators are connected between the base and the lift supports by lifting yokes to selectively raise and lower the front and back ends of the machine. The movable platform may be connected to move along the exercise machine by trolley wheel assemblies. A plurality of travel limit decelerators mounted on the rails engage and rapidly decelerates the movable platform as it reaches its limits of travel on the rails.

A multifunctional cardiovascular exercise machine may include a frame including a first and second end attached to one another by a pair of ski rails and a centrally located center frame rail. A flywheel may be operatively mounted to the frame, and a pulley system may be mounted to the frame, the pulley system supporting and routing a pull rope, wherein the pull rope is operatively engaged with the flywheel, and a free end of the pull rope is removably engaged with a pull bar, a pair of ski poles, and/or a pair of pull handles. A sliding seat may be operatively attached to the flywheel and slidably mounted to the center frame rail, and a pair of footrests may be mounted to the frame proximate to the flywheel.

An exercise equipment arranged on a floor so as to surround an exerciser and to have a frame having a shape that lacks one side of a rectangle, includes a first longitudinal horizontal bar connected to the frame, arranged at a predetermined height from the frame, and aligned in a depth direction, a first transverse horizontal bar connected to the frame, having one end thereof connected to the first longitudinal horizontal bar, and aligned in a direction different from the first longitudinal horizontal bar, a vertical bar connected to the frame, and having a height from the frame that is higher than the first transverse horizontal bar, and a second longitudinal horizontal bar connected to the frame, arranged in parallel to the first longitudinal horizontal bar, and spaced from another end of the first transverse horizontal bar.
