A strength training equipment, comprising: a torque producing mechanism, a weight pulling mechanism, a controller, and an electronic instrument; wherein the torque producing mechanism is composed of the deceleration machine and the winding wheel connected to each other on the same shaft, a belt is winding on the winding wheel, and the free end of the belt is connected to the force applied unit of the weight pulling mechanism; a movement path sensor installed on the winding wheel, and an angle sensor installed at the lateral side of the guide pulley of the weight pulling mechanism; whereby inputting required torque value by electronic instrument, the servo control unit will drive the motor to produce torque, the user will have to against the torque while applying force to the extension element and the swinging element, so achieve the effect of strength training.

A weightlifting machine includes a frame assembly having a plurality of pulleys that are connected to a user grip and plurality of weighted panels. A plurality of proximity sensors are positioned along the frame assembly and function to identify a specific number of weighed panels being lifted during an exercise routine. A location sensor is provided along the frame assembly and functions to identify the speed and distance at which the weighted panels move. A system controller is communicatively linked to each of the sensors, and a motor is connected to the cable and pulley assembly. The system controller includes functionality for selectively activating the motor to aid or resist the user in moving the weighted panels based upon the sensor information. The system controller further including a memory and communication unit for storing exercise information of the user.

An exercise machine resistance adjustment system for providing an exerciser the ability to immediately adjust the resistance force by changing their body position on the movable carriage or end platforms. The exercise machine resistance adjustment system generally includes a frame, a carriage movably positioned on the frame, a spring connected to the carriage to apply a biasing force to the carriage, one or more left projections within the carriage adapted for a left hand of an exerciser to grasp, and one or more right projections within the carriage adapted for a right hand of an exerciser to grasp. The exerciser is able to efficiently adjust the amount of resistance force applied to the carriage by repositioning their hands (or feet) from a first set of projections at a first distance to a second set of projections at a second distance from the first end of the exercise machine.

An exercising device includes a base placed on a plane, a cover pivotally connected with the base, and an exercise apparatus mounted between the base and the cover. The cover has a side pivotally mounted on a side of the base. The cover is pivoted relative to the base to open or close a top face of the base. The exercise apparatus includes a leg working unit mounted on the base. Thus, the exercising device is stored easily and conveniently and is adapted to function as furniture. The exercising device also has a dustproof function.

A pull-up fitness exercise machine with a grip bar hanging frame structure for a hang-up training includes a support board. The support board is automatically lifted upward by a pushing unit for the user to take an expected pull-up exercise. The pushing unit is activated by an electric adjusting element in a mechanism box unit for a proper adjustment of the pushing force. The support board is provided with a hand-operated switch unit and a foot-operated switch unit for cooperating with their corresponding barbed hooks respectively, such that the support board can always be kept at a relatively low position in the case that the foot-operated switch group is not stressed. The whole machine body consists of a left and right symmetrical front frame and a rear frame having a forward extension rail. The bottom end of the front frame naturally forms two front ground feet, and further forms a solid ground support together with the bottom end of the rear frame. The mechanism box unit and a supporting plate link are pivotally connected to a pivot shaft of the rear frame. The pushing unit is further pivoted between the mechanism box unit and the extension rail. A hanging frame having a plurality of corresponding hanging bars is positioned on both top ends of the front frame for providing a random hanging of a grip bar with a safety sling.

A punching-training device is provided, including: a support body, having a seat end and an assembling end; and a punching mechanism, including a first punched member which is freely rotatably assembled to the assembling end and a pad, the first punched member including a body portion disposed around the assembling end, the pad being disposed on and rotatable together with the body portion.

A modular group therapy matrix apparatus includes tubular grip bars positioned in parallel longitudinal rows and transverse tubular grip bars which span between the rows. The grip bars are interconnected by a plurality of upright supports. Each upright support includes spring loaded snap couplings which are received within the ends of the hollow grip bars and which engage apertures in the grip bars to facilitate easy assembly and disassembly of the matrix. Physical therapy patients may grasp the grip bars, which comprises the outer periphery of the matrix, to perform exercises. A physical therapist or trainer may be positioned within the matrix to demonstrate exercises.

A multi-axis adjustable exercise machine which is pivotable about both a pitch axis and a roll axis with respect to a base for allowing an exerciser to perform a wide range of exercises on a pitched or rolled exercise machine. The multi-axis adjustable exercise machine generally includes an exercise machine which is adjustable with respect to a base. The exercise machine may be pivoted about a roll axis to adjust the roll angle of the exercise machine or may be pivoted about a pitch axis to adjust the pitch angle of the exercise machine. One or more actuators may be connected between the base and the exercise machine to effectuate the pivoting of the exercise machine about either or both axes with respect to the base.

The invention is embodied in an exercise system that can allow its user to counterbalance the effects associated with a predominantly sedentary lifestyle though a fitness device that comprises a combination of (a) supporting the lower body in a manner that permits a user's upper body to act as a third class lever with the user's hips operating as fulcrum and (b) engaging in resistance exercises with the upper body in a horizontal position, unsupported above the greater trochanter.

An electrorheological fluid which comprises a dispersion medium containing fluorine atoms in an amount larger than 0 wt % but not larger than 50.0 wt % and particles for electrorheological fluid use that are contained in the dispersion medium in an amount of 10-50 vol % of the total volume of the dispersion medium and the particles, the particles comprising a sulfonic-acid-group-containing polymer having a sulfonic acid group content of 30-70 wt %.
