A resistance component configured for imparting a resistive force to a connected exercise component is provided. The device includes a frame pivotally supporting a selection arm which has a weight operatively connected to the selection arm by a pin arm. The weight imparts a force resisting rotation of the selection arm by a flexible member engaged with the exercise component. Adjusting the engagement of one end of the pin arm to an arched engagement path along the selection arm adjusts mechanical advantage and the resistive force.

A hip thrust exercise device includes a main body; a foot mount connected to the first body portion; a grip connected to the second body portion; an extension hingedly connected to the main and an abutment element; and a resistance element connected between the extension and main body. The resistance element provides a resistance force when the abutment element is moved away from the first body portion.

A therapy device aids an occupational therapist in soft tissue recovery and development. The device includes an attachment base which anchors to a table or other support surface, a riser pivotably connected to the base with 2-3 degrees of freedom, and a handle connected to the riser with an additional 2-3 degree of freedom. Each pivotable connection can be adjusted to rotate freely or with a desired level of friction, or can be locked in a desired configuration. Multiple interchangeable handles may be included to adjust the patient-device interface, e.g., unilateral or bilateral engagement. Height adjustments may also be provided. The dual-pivoting design and adjustability of the device facilitates applications for a wide variety of patients with varying therapeutic needs.

An exercise mechanism for a training machine is disclosed wherein the training machine includes a machine base and at least one handle which is operable to swing. The exercise mechanism includes at least one support and a rotary disk, wherein the at least one support is pivotally connected to the machine base and has a first end and a second end which are respectively on two sides of a portion pivoted to the machine base; the at least one support moves to generate a relative up and down displacement between the first end and the second end when the handle swings; the first end is pivotally connected to the machine base via a linkage assembly; the rotary disk would be driven to rotate when the second end moves whereby the exercise mechanism is capable of operating the training machine.

A system for providing resistance in an exercise machine. The system includes a motor, at least one drive screw attached to the motor. A carriage is coupled to the drive screw. The carriage moves in a first direction when the drive screw is turned in a first direction and a second direction when the drive screw is turned in a second direction. At least one sensor is attached to the carriage, wherein the at least one sensor is configured to detect external force on the carriage. Information from the sensor indicates external force on the carriage. The information is used to determine a movement of the carriage in response to the external force. The motor is instructed to turn the drive screw to apply the movement.

Apparatus for performing a pull down exercise comprising: a frame, a seat, an input arm assembly interconnected to a resistance mechanism and a manually graspable mechanism disposed vertically above the user's trunk in a start sitting exercise position, the input arm assembly being pivotably mounted on the frame for back and forth travel along a generally forward to rearward direction and along a generally side to side direction orthogonal to the forward to rearward direction, the input arm assembly being rotatably pivotable around a first linear axis and a second linear axis in the respective directions on exertion by the user of a rearwardly downwardly directed force on the manually graspable mechanism.

A device for an exercise apparatus includes a linear adjustment system and a sensor coupled to the linear adjustment system. The exercise apparatus includes a loading interface and a frame coupled to the loading interface for performing an exercise. The linear adjustment system fixes the loading interface of the exercise apparatus at any one of a plurality of functional positions in a functional range of the loading interface. The sensor measures the force exerted on the linear adjustment system. A correlating mechanism is used to correlate the force exerted on the linear adjustment system with the force exerted on the loading interface. The device allows exercisers to exert high or maximum loads in any one of a plurality of positions throughout their entire range of motion without first passing through a weak range of motion.

An exercise machine may include a frame, a base portion of the frame, a deck pivotally connected at a rear end, an upright structure of the frame, a handle movably attached to the frame, and a linkage connecting the handle to the first end of the deck. An elevation of the first end of the deck changes when the handle is moved.

A machine for concurrently performing pressing motions with the hands and feet, the machine having a base having front and back ends, two or more user supports, at least one lower body user support with an engagement means for the user's feet and at least one upper body user support with an engagement means for the user's hands. The upper body user support and lower body user support move fore and aft on opposing ends of the base frame and at least one of the upper body user supports and at least one of the lower body user supports cooperate with one another to move in opposing fore and aft movement patterns during operation of the machine.

An apparatus for an exercise task includes a pneumatic arrangement, which includes a pressure source, a pneumatic controller, pneumatic transfer channels, and at least one pneumatic resistor element, which includes a pneumatic cylinder with its piston. The apparatus additionally includes a mechanical lever arm structure or another mechanical connecting structure, which is for a user's limb contact and which is at a second end connected to the pneumatic resistor element. The apparatus additionally includes a sensor structure, a calculation arrangement and a display. The sensor structure is arranged to measure at least one measurement quantity of the exercise task and, based on the measurement, the calculation arrangement is arranged to form information on the display of the apparatus, regarding the power and/or force and/or range of motion of the exercise task. In the invention, regardless of the number of pneumatic resistor elements, the sensor structure includes one pressure sensor only, and to compensate for the small number of sensors, the calculation arrangement includes a correlation-taught calculation unit, which comprises a correlation algorithm taught with a larger number of sensors than the number of sensors in the apparatus, concerning the correlation between power and/or force and/or range of motion of the exercise task and the measured information.
