A transmission structure of a climbing machine for an operator to operate in a standing position is disclosed. The transmission structure of the climbing machine includes a base, a support frame, a first slide rail, a second slide rail, a first transmission unit, a second transmission unit, a first handle slider, a first pedal slider, a second handle slider, a second pedal slider, and a resistance unit. The climbing machine is used to train the synchronized and coordinated movements of hands and feet for simulating rock climbing and mountaineering. The support frame, the first slide rail, the second slide rail, the first transmission unit and the second transmission unit are all located at the center line position of the upright trunk of the operator. The volume of the climbing machine can be reduced greatly to save the space occupied.

An exercise apparatus includes a frame with a pair of vertical guides. A carriage is slidably carried on each of the guides. Each of the carriages has a locking mechanism to lock the carriage at a selected vertical position and a release to disengage the locking mechanism. A horizontal exercise bar is slidably carried on guide rods. First and second cables are coupled to a selectable exercise resistance, each of the cables having an end selectively coupled to either the respective carriage or to a respective bracket at the end of the exercise bar. Secondary brackets on the exercise bar are configured to engage respective ones of the carriage releases and grab the carriage so as to selectively engage and disengage the locking mechanisms upon axial rotation of the exercise bar and raise and lower the carriages with the exercise bar.

The present invention pertains to a spring resistance exercise machine including an adjustable spring carriage and anchor housing and having cable and pulley linkage assemblies attached to a plurality of springs, or other resistance sources. Each cable and pulley linkage assembly, which is independent of the other(s), can be used unilaterally (by one arm or one leg at a time) or bilaterally (by both arms or both legs at a time) during exercise resistance training (that is, training in which both limbs of a pair are used to simultaneously pull a certain resistance).

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.

The present invention relates to an exercise method and an exercise device for performing an exercise suitable for thigh and hip muscles like fitness equipment or an exercise bicycle, and more particularly, to an exercise method and an exercise device for strengthening thigh and hip muscles by performing a movement of lowering legs and then moving the legs backward or putting the legs together or apart from a position of pulling the legs toward a chest of the user with an arm disposed between the legs in a sitting or lying position of the user. In addition, the present invention relates to a leg exercise device including a trajectory measuring device of generating motion range information of the exercise device and making the motion range information as data through a motion range measurement sensor attached to a knee and a hip joint of the user seated on the exercise device, smart device and an application of the smart device.

Provided herein are embodiments of a barbell spotting apparatus having all the benefits of a free-floating, unconstrained barbell in both the horizontal and vertical axes with the safety of a dedicated spotting mechanism, while addressing safety, noise, and space concerns raised by typical barbell apparatus. The embodiments herein permit a loaded barbell to be positioned in line with the axis of motion of the lift to be performed at both the beginning and end of the lift.

An exercise machine may include a frame, a resistance mechanism supported by the frame, first and second pull cables supported by the frame and linked to the resistance mechanism, a power rack attached to the frame, first and second handles selectively attachable to the first and second pull cable, and first and second pulleys. The power rack includes upright posts configured to have barbell holders adjustably attached thereto such that the barbell holders are configured to be adjusted in various positions between highest positions and lowest positions on the upright posts. The pulleys are configured to selectively receive the pull cables to enable the pull cables to be selectively attached to a barbell to assist or hinder a user in lifting the barbell in a combined cableand free weight workout, the pull cables decoupled from the pulleys for cable workouts.

An exercise machine is disclosed. The exercise machine comprises a pancake motor. The exercise machine comprises a torque controller coupled to the pancake motor. The exercise machine comprises a high resolution encoder coupled to the pancake motor.

An exercise machine resistance selection system for efficiently and easily adjusting a resistance force applied against movement of a carriage in at least one direction. An exercise machine includes a frame having at least one rail and a carriage movably connected to the at least one rail. A biasing member is selectively and removably connected to the carriage by a first catch member, with the first catch member being adjustable between an engaged position in which the first catch member is adapted to engage with the biasing member to impart a resistance force against movement of the carriage and a disengaged position in which the first catch member is adapted to release biasing member. A first retaining member is adapted to retain the biasing member in place below the carriage when the biasing member is released from the first catch member.

An exercise system includes a base structure including a first cross brace including first cross brace mounting plates disposed at each end of the first cross brace. A pair of base guide rail supports is secured to and extended substantially orthogonal from the first cross brace and includes a pair of base guide rail receivers. A pair of base pulley supports is secured to and extended substantially orthogonal from the first cross brace and further includes a pulley-support pulley housing. A pair of pulley-support pulleys is rotatably secured to the pulley-support pulley housing. A second cross brace includes a central portion substantially parallel to the first cross brace. The central portion is secured to the pair of base guide rail supports and the pair of base pulley supports. Two end portions are disposed at an angle to the central portion and terminate at second cross brace mounting plates disposed at each end of the two end portions and two central-portion pulley housings. A central-portion pulley is rotatably secured to each of the two central-portion pulley housings.
