A preloaded resistance pack and exercise device. The resistance pack includes an elastomeric resistance element coupled to a hub and disposed on a plate. The hub includes a pair of radially extending wings that lie against a surface of the plate. The plate includes a pair of raised tabs that lie within a rotational path of the wings. An initial rotation of the hub relative to the plate causes the wings to slide over and beyond the raised tabs and at least partially stretches the resistance element. Interaction between the tabs and wings prevents the hub from rotating back to an initial position and maintains the resistance element in a preloaded, tensioned condition. The exercise device is configured to detect a number of the resistance packs coupled thereto as well as data associated with exercise movements employing the resistance packs.

An exercise machine includes a shaft configured to rotate about an axis; a spool configured to receive a strap and drive rotation of the shaft about the axis in response to movement of the strap; a flywheel configured to rotate about the axis; one or more conductive coils arranged to generate magnetic fields that induce eddy currents in the flywheel; a clutch configured to engage and disengage transmission of torque between the spool and the flywheel; and a spring arranged around the axis, the spring configured to exert a return torque on the spool about the axis in response to rotation of the shaft.

An actuator and an exercise equipment using the same are disclosed. The exercise equipment comprises a post which is a main body of the exercise equipment, a shoulder installed on an upper side of the post and rotates in left and right direction, an arm combined with the shoulder and rotates in up and down direction, a hand combined with one terminal of the arm and rotates by using the arm as an axis, a handle located on one terminal side of the hand, a force control actuator outputs a force corresponding to weight set by a user, and a wire passes via plural sheaves included in the hand, the shoulder and the post and deliver a force generated by pulling of the handle, one terminal of the wire being connected to the handle.

An exercise machine monitoring and instruction system for the movement of an element of an exercise machine by an exerciser and providing automated feedback to the exerciser to help improve the exercise in real-time. The exercise machine monitoring and instruction system generally includes an exercise machine having a movable element that moves between a first position and a second position in a reciprocating manner, a sensor that detects a real-time position of the movable element, a processor in communication with the sensor to receive the real-time position data from the sensor related to a position of the movable element and a feedback device in communication with the processor that provides real-time instructions to the exerciser on how to adjust their workout to achieve a desired result.

An exercise assembly structured to perform different rowing routines characterized different rowing motions. A resistance device is movable within a chamber and is cooperatively structured therewith to resist such movement. A drive assembly includes two drive sections each independently connected in driving relation to said resistance device. A connector structure includes two connector members each attached to a handle and connected in driving relation to a different one of said drive sections. The handle is selectively movable through the plurality of different rowing motions, at least one of which results in the two drive sections concurrently driving the resistance member and being concurrently driven by the two connector members. At least one other rowing motion of the handle is defined by each drive section alternately driving the resistance member and being alternately driven by interconnected ones of said connector members.

This invention is a portable exercise system capable of performing multiple exercises for strength and endurance training. The key component is the force generation unit (FGU) which is small and light enough to be suspended during the exercise yet capable of producing a force of 50 lbs. The FGU is programmable allowing it to generate various force vs distance, time or velocity profiles. Different handles, cables and attachments can be connected or used with the FGU perform different exercises. The FGU can charge its battery from the user's energy during use. The FGU can communicate bidirectionally with computers and smart phones for setup and to track the user's performance. Multiple FGUs may be used simultaneously each performing a separate function. The entire system is small enough to fit in a drawer or suitcase. The accompanying software can track the user's performance and function as an automated personal trainer.

The present disclosure relates to an exercise machine for performing a gymnastic exercise, comprising a first exercise device, in turn comprising at least one first cable, and at least one first handle, coupled to said first cable, to allow a user to perform a gymnastic exercise, and a second exercise device, in turn comprising at least one second cable, and at least one second handle, coupled to said second cable, to allow the user to perform a gymnastic exercise, said exercise machine further comprises a first actuator, connected to said first cable, for exerting a drive or resistant torque on said first cable, a second actuator, connected to said second cable, for exerting a drive or resistant torque on said second cable, and a logic control unit, connected to said first actuator and said second actuator, for adjusting said drive or resistant torque.

A towing equipment used to train athletes' speed, strength and agility is disclosed to include a training unit, a magnetic resistance unit and a transmission mechanism. By an elastic training belt of the training unit, the towing equipment is connected to the human body. The kinetic energy generated by the human body pulling the elastic training belt is transmitted to the magnetic resistance unit through the transmission mechanism to generate resistance. The magnetic resistance unit includes a magnetic device set and an adjustment device set. The user can adjust the resistance generated by the magnetic device set through the adjustment device set. The magnetic device set includes a resistance wheel set on the frame body and a bearing block set corresponding to the resistance wheel. Use the overlap area of a magnetic field in the resistance wheel and the bearing block to generate magnetic flux.

A user interface for an interactive exercise system includes a display module held by a mechanical support system, with the display module able to display a video of a trainer. The trainer can be presented in full body view against a black background and a mirror element attached to at least partially cover the display module.

A modular resistance force system includes an axle configured to be rotatable around a rotational axis and one or more resistance mechanisms. Each of the one or more resistance mechanisms includes a resistance element disposed about a portion of the axle, a resistance element housing configured to house the resistance element and a resistance substance disposed between the resistance element and the resistance element housing. Either the resistance element or the resistance element housing is selectively engaged to rotate with the axle. A resistance between the resistance element and the resistance substance causes a force to be applied to the axle when the resistance element and the resistance element housing move relative to each other.
