A portable exercise system that can be attached to the uprights on any commonly available training rig, squat stand, or power rack, and for resistance can use any attachable weight. The system includes an upper pulley assembly, a lower pulley assembly and an anchor assembly. The anchor assembly utilizes a wedge and block to set the cable length and is adapted to attach the weights. The upper pulley assembly includes pulleys to keep the cable aligned and the resistance coming from above. The lower pulley assembly could be hinged for an additional degree of freedom. The cable runs through the lower pulleys, to the upper pulleys, and down to the anchor and weights. The other end of the cable has a fixed loop for attaching a handle for the user.

An information processing apparatus (100) according to the present application includes two or more force sensors (110) that each detect a force of two or more different fingers of a user, and a processing unit (122) that executes information processing related to measurement of forces of the two or more different fingers based on detection results detected by each of the two or more force sensors (110).

An exercise device includes a base defining an inner volume and a top supported by the base, the top defining an aperture. The exercise device further includes a force sensor configured to measure force on the top and a motor disposed within the base and below the top, the motor including a cable extendable through the aperture. The exercise deice further includes a controller communicatively coupled to each of the force sensor and the motor. The controller is adapted to actuate the motor in response to forces applied to the top as measured by the force sensor. The controller may also actuate the motor in response to one or more additional parameters related to the speed or force with which the cable is manipulated (e.g., pulled by a user).

A workout system is provided that includes a piece of furniture having at least a backrest and a seat. A chair workout machine is provided coupled to the piece of furniture. The chair workout machine includes a support frame coupled to at least one structure of the piece of furniture. At least one rotatable arm is rotatably attached to the support frame. One or more resistance elements are coupled to the at least one rotatable arm, where the resistance elements arranged to provide resistance to movement by at least one body part of a user.

A safety signal is sent to a relay coupled to a plurality of power leads of a motor wherein a default state of the relay is to short the plurality of power leads together and wherein the safety signal maintains the relay in an open state. The safety signal to the relay is deasserted in response to a determination that an unsafe condition has occurred.

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.

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 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.

An electro-mechanical displacement exercise apparatus for processing a maximum force potential of an athlete, including a frame a frame including a platform, wherein a section of the platform is connected to a tower, whereby the tower houses control means for manipulating a tension supporting member connected to a force bearing member, a first pull location, whereby the first pull location is positioned on the platform and within the frame and whereby the first pull location is operatively connected with a portion of the tension supporting member, whereby a user may exert a force on the tension supporting member operatively connected to a first actuator; and wherein the first actuator is housed within the tower, and whereby the first actuator includes a motor coupled to a gearbox.
