A foldable rowing machine comprises a main part, a rowing machine seat, at least one drawing stand, and at least two turning stands. A storage chamber is formed in the main part, and a pedal is hinged to an opening of the storage chamber. A rope winder for winding a rope to a required length is disposed on main part, and a damping adjustment device for realizing a damping adjustment effect by means of magnets and a metal ring is disposed at position of a damper. A whole frame can be folded to be stored, the rope can be wound by a short distance, damping force of the damper can be freely adjusted, and a movable frame for avoiding a high-low clearance is disposed on turning stands to fulfill a shock absorption effect; and various functions are realized, and user experience of the rowing machine can be effectively improved.

A limb exercise machine includes a first transmission unit and a second transmission unit. A left-hand control member, as well as a right-foot control member, is connected to the first transmission unit. The left-hand control member and the right-foot control member are pulled by the first transmission unit to be moved synchronously. A right-hand control member, as well as a left-foot control member, is connected to the second transmission unit. The right-hand control member and the left-foot control member are pulled by the second transmission unit to be moved synchronously.

An exercise machine tension device securing system for safely and efficiently securing selectable biasing members to an exercise machine. The exercise machine tension device securing system generally includes an exercise machine including a frame and a carriage movably positioned on the frame. A plurality of tension devices may be connected to the frame at one end; with the other end being removably connected to the carriage by a selection device. The selection device may include a plurality of slots for removably receiving one or more of the tension devices to secure the tension devices selectively to the carriage. A securing member movably connected to the selection device includes projections adapted to selectively enclose the slots so as to secure the tension devices within the slots of the selection device.

A fitness exercise apparatus includes a base member, a support unit disposed on the base member, and a slide bar disposed on the support unit. A seat frame includes a connector connected to and slidable along the slide bar, a guide rail connected to the connector, and a foot post connected to the guide rail opposite to the connector. A swing frame is connected to the guide rail at a position corresponding to the foot post. An elastic cord unit includes a plurality of first and second elastic cords connected to the support unit. A pulling unit includes two first cables connectable with the first elastic cords. An operating unit is connectable with the first cables.

A fitness exercise apparatus includes a base member, a support unit disposed on the base member, and a pivot assembly disposed on the support unit. A seat frame includes a guide rail having a front end provided with a pivot connecting member pivotally connected to the pivot assembly. The seat frame is pivotally movable to different angular positions relative to the base member. An elastic cord unit includes a plurality of first and second elastic cords connected to the support unit. A pulling unit includes two first cables connectable with the first elastic cords. An operating unit is connectable with the first cables.

A paddling simulator includes a bar, a cable attached to the bar, a motor operationally coupled to the cable such that the motor can apply a force to the cable, and a controller configured to control the motor to generate a first tension in the cable during a propulsion phase of a paddling stroke and a second tension in the cable during a recovery phase of the paddling stroke.

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 leg exercise assembly includes a housing that is positionable near a user's feet. A pair of foot pads is each disposed on the housing for having a respective one of the user's feet positioned upon the foot pads. A pair of roller units is each rollably integrated into the housing and each of the foot pads is coupled to a respective one of the pair of roller units for sliding the foot pads back and forth on the housing. A resistance unit is movably integrated into the housing for either increasing or decreasing the force required to move the footpads to accommodate the physical strength of the user. A calorie counter is integrated into the housing and the calorie counter counts each time the pair of roller units is moved back and forth to calculate the calories being burnt by the user.

An abdominal exercise roller with a powered wheel mechanism to assist the user during the abdominal exercise routine. The invention includes utilizing sensing technology and the electronic module to control the motor and optimize the performance of the abdominal roller during the exercise routine.

An exercise bench includes a base, a slidable seat coupled to and slidable along the base, and a removable pad positionable on frame. When the removable pad is positioned on the frame, the removable pad prevents movement of the slidable seat along the base and provides a static bench surface configured to support a user during a strength training exercise.
