A rowing simulation trainer includes a base frame, a pulling unit, an inertia wheel unit and a guiding unit. The pulling unit includes a shaft, a first belt wheel, two cord wheels, two pulling cords, two handgrips and two elastic coiled plates. The guiding unit includes two mounting tubes. Each of the two pulling cords extends through one of the two mounting tubes. Thus, the two cord wheels and the two pulling cords cooperate to drive the inertia wheel unit and are respectively operated independently without interfering with each other. In addition, the two pulling cords are limited by the two mounting tubes so that the two pulling cords are kept in line with and will not be deflected from the two cord wheels.

An adjustable resistance exercise machine for providing variable resistance forces on a pull cable extending from the machine. The adjustable resistance exercise machine generally includes a plurality of power springs that may be selectively engaged using a cam mechanism. By engaging springs with different forces, the resistance may be adjusted incrementally as preferred for performing different exercises. The adjustable resistance exercise machine may be connected to various structures, either below or above an exerciser, to allow the exerciser to choose whether to pull the pull cable up or down during exercise.

Example embodiments relate to a system, method, apparatus, and computer readable media configured to generate a multiple renditions of a user interface that is updated based upon athletic movements of two or more users remotely located from each other. The UI may be configured to simultaneously display energy expenditure values in real-time. In further embodiments, a joint energy expenditure values determined from multiple remote users may be simultaneously displayed.

A gymnastics apparatus, comprising an at least semicircular arc structure which is adapted to define a pair of rails along which at least one body can move on which at least one cable can be unwound and wound, in contrast with a resistance, said cable being adapted to be gripped by a user who positions himself or herself proximate to the at least semicircular arc structure.

A cable exercise machine includes a first pull cable and a second pull cable incorporated into a frame. Each of the first pull cable and the second pull cable are linked to at least one resistance mechanism. The at least one resistance mechanism includes a flywheel and a magnetic unit arranged to resist movement of the flywheel.

A locking device for an exercise system may include at least one moveable assembly that is in communication with a resistance mechanism. The locking device has an actuating device for selectively engaging the locking device, a locking member having a contact portion, wherein the contact portion of the locking member is not in contact with the resistance mechanism of the exercise system when the actuating device is in a first position, thereby allowing movement of the at least one moveable assembly, and wherein the contact portion of the locking member is in contact with the resistance mechanism of the exercise system when the actuating device is in a second position, thereby preventing movement of the at least one moveable assembly.

A strength training assembly includes a stand and a frame movable along the stand in a vertical direction. The frame includes a cradle configured to receive a barbell. The strength training also includes a drive system coupled to the frame and controllable to affect a velocity of the frame relative to the stand, a force sensor coupled to the frame such that the force sensor moves with the frame, the force sensor configured to provide a signal indicative of an amount of force exerted on the force sensor by a user, and a controller configured to receive the signal from the force sensor and control the drive system such that the velocity of the frame varies as a function of the amount of force exerted on the force sensor.

An exercise apparatus includes a platform including an exercise surface, a rack coupled to the platform and configured to support a barbell at a first end of the platform, and a bench assembly coupled to the platform and configured to pivot between a deployed orientation in which the bench assembly extends perpendicularly from the rack and is positioned over the exercise surface for use during performance of a first exercise and a stowed orientation perpendicular to the deployed orientation and in which the bench assembly is displaced from the exercise surface to enable performance of a second exercise without using the bench assembly.

A physical training apparatus includes a housing, a flywheel mechanism accommodated in the housing, the flywheel mechanism including a spindle, at least one flywheel mounted on the spindle and bearings to support the spindle in the housing, a windable pull element, such as a pull cord or band, which is arranged to be wound up the spindle and unwound from the spindle, and a handgrip attached to the pull element. The spindle includes a spindle end portion. The flywheel is exchangeably mounted on the spindle end portion against a stop located on the spindle. A fastening knob is releasably coupled to the spindle end portion and adapted to engage the flywheel and force it against the stop located on the spindle.

A self-exercise device that provides resistance to tugging, and is operable to intermittently change the resistance so as to mimic an actual tug-of-war game. The device includes ball gallery and ratchet structures that cooperate to provide additional intermittent resistance to provide action to the device that mimics an actual tug-of-war experience wherein the opposing resistance is randomly changing.
