An ankle exerciser for exercising a user's ankles and includes a base, two pedals and two rotary units. The pedals and the rotary units are installed to the base. The rotary units are located between the base and the pedals so as to allow the pedals to be pivoted in multiple directions so as to stretch the ankles, and to keep ankles healthy.

A resistance adjustable exercise device, including a resistance assembly to provide resistance to movement, a handle assembly connected to at least a portion of the resistance assembly to move the resistance assembly in at least one of a first rotational direction and a second rotational direction, and a control unit disposed on at least a portion of the handle assembly to adjust at least one of a first resistance level and a second resistance level of the resistance assembly.

An exercise machine is disclosed. The exercise machine comprises a motor. The exercise machine comprises a gearbox coupled to the motor, wherein the gearbox comprises bevel gears. The exercise machine comprises a spool coupled to the gearbox. The exercise machine comprises a cable wound about the spool. A second exercise machine is disclosed. The second exercise machine comprises a motor. The second exercise machine comprises a lockable translatable mount. The second exercise machine comprises a cable coupled to the motor via the lockable translatable mount. The second exercise machine comprises a sensor coupled to the lockable translatable mount, wherein the sensor is used at least in part to determine mount lock state. A third exercise machine is disclosed. The third exercise machine comprises a motor. The third exercise machine comprises a mount. The third exercise machine comprises a cable coupled to the motor via the mount. The third exercise machine comprises a sensor coupled to the mount, wherein the sensor is used at least in part to determine mount lock state. The third exercise machine comprises a lockable arm coupled to the mount and a second sensor coupled to the lockable arm, wherein the second sensor is used at least in part to determine arm angle.

A device for exercising upper leg portions and hips which includes a frame, an arm pivotably connected to the frame, and a leg pad pivotably connected to the arm and configured to contact the user's leg during use. The frame having an arm strut and a seat strut. The seat strut having a seat location fixing unit defined by a seat location fixing rod and a seat location fixing place. The seat location fixing place is connected to the frame having laterally spaced apart vertical holes therein for insertion of the seat location fixing rod which attaches to an underside of the seat and is configured as a support post between the seat and the holes within the seat location fixing place. The holes are configured for the user to locate said seat location fixing rod at varying distances and locations from the arm strut.

An exercise apparatus having an upper body portion and a lower body portion, the upper and lower body portions positionable in a substantially horizontal position to accommodate a user in a kneeling position. A connector connects the upper and lower body portions. First and second resistant members are attached to the one or both of the upper and lower body portions. The body portions can be movable between a closed folded position and an open position.

An exercise device is described which includes a platform having a first end and a second end opposite the first end; first and second wheels, wherein the first wheel is positioned proximate the first end and the second wheel is positioned proximate the second end and the first and second wheels are configured to roll across a surface as the exercise device is displaced along the surface; a first motor configured to apply a first torque to the first wheel where the magnitude of the first torque is related to the distance of the exercise device from a zero position and the direction of the first torque urges movement of the exercise device toward the zero position. Versions are also described with more wheels and more motors.

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.

A resistance device capable linearly adjusting training load comprising: a rack unit with two vertical rods, and two sliding units, which are connected to a handle and a pedal; a linkage unit with a chain and a belt, and are locked on the connecting plate; and two damping units make multiple magnet pieces arranged on both sides of a fixing base, and a diamagnetic metal piece is arranged on the connecting plate, and set trough the fixing base to cut the magnetic circuit generated by the magnet pieces to form damping: When the user steps on the pedal, the connecting plate will drive the metal sheet to cut the magnetic circuit, and the damping can be changed to further achieve the effect of linearly adjusting the training load.

Interactive/smart resistance band training systems include one or more resistance bands connected to a force sensing unit that registers the force exerted by a user on handles connected to the bands. The sensing unit operates effectively regardless of whether the user is training with one handle individually, or with two handles being pulled in parallel or non-parallel directions. The systems may correct the force readings to account for non-alignment between the force-measurement axis of the force sensing unit and the directions in which the user applies force to the resistance bands. The systems may guide a user through exercise sessions tailored to the fitness level of the user; may display the force readings, calories burned, and other performance parameters and goals on a continuous, real-time basis; may summarize the result of the exercise session; and may recommend subsequent exercise sessions based on the performance of the user.

A method of treating elbow tendonitis in a user's arm comprises providing a container having a handle, filling the container with a prescribed volume of water, holding the container by the handle with the arm hanging at the user's side in a starting position defined by an inward facing of the user's palm, thereafter, rotating the container in a first direction until the arm is at a first rotated position defined by an outward facing of the user's palm, holding the arm at the first rotated position for a first hold time of at least six seconds, thereafter, rotating the container in a second direction opposite the first direction, past the starting position, until the arm is at a second rotated position defined by an outward facing of the user's palm, and holding the arm at the second rotated position for a second hold time of at least six seconds.
