An exercise device includes a frame, a movable engagement surface connected to the frame and movable in the performance of an exercise, and a display located adjacent to or below at least a portion of the movable engagement surface.

An elliptical machine includes a machine frame and two pedal units each including a vertical arm having a top end pivotally connected to the machine frame and swingable back and forth, a driving main arm having a front end arranged on an opposing bottom end of the vertical arm in a vertically swingable manner, a pedal mount arranged on an opposing rear end of the driving main arm and swingable left and right, a pedal arranged on the pedal mount and swingable left and right, a slanting rod having a front end arranged on the vertical arm in a vertically swingable manner and an opposing rear end arranged on the pedal mount in a universally rotatable manner, and a rocking link that has a front end arranged on the rear end of the driving main arm and swingable back and forth and up and down.

A leg exercise machine includes a frame and a swinging mechanism. The swinging mechanism includes two parallel tubes, four swinging rods and two pedals. The tubes are supported on the frame. Each of the pedals is connected to two corresponding ones of the swinging rods. Each of the universal joints connects a corresponding end of a corresponding one of the tubes to an upper end of a corresponding one of the swinging rods.

An electromechanical device for simulation of physical exercise with legs and arms includes two pedals mounted on two contiguous pantographs, with parallel supporting arms that are positioned in a predominantly vertical sense, with an orthogonal junction and parallel arms which are articulated, in a predominantly horizontal sense, onto the frame of the device and which always move in opposing directions left and right, through traverses which are articulated on vertical and horizontal axles, respectively, connected to vertical and horizontal parallel bars by means of risers.

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 stepper exercise machine is provided. When a pedal is pedaled by a user, a drive gear is rotated forward or rearward. One end of a link is rotated about a drive rod, and a turning lever connected to the other end of the link is confined by a second accommodation trough of the pedal, so that the link brings the pedal to move in the up-down direction and the front-rear direction. In cooperation with a shaft which is fixed, a sleeve is rotatable relative to the shaft. When the pedal is driven, a first accommodation space provides a space for the pedal to move in the front-rear direction. By means of the action of two flywheels to provide an acceleration effect, the rotation of the drive gear is to speed up, so that the user can reduce the force exerted to the pedal.

The present invention provides an upper body exercise apparatus that is portable, is compatible with various other workout machines such as stationary bikes and treadmills and is advantageous for safe, low-impact cardiovascular exercise. The exercise apparatus comprises a pair of movable handlebars that are activated by push and pull forces exerted by the user. A clamp sub-assembly is provided by which a user may attach the exercise apparatus to a separate free-standing machine, such as a stationary bike or a treadmill. A brake sub-assembly is also provided and serves to create a braking effect that results in a feeling of resistance to the user as the user moves the handlebars in a substantially forward or rearward direction.

An adjustable resistance system for use with an indoor cycle comprising a magnetic resistance assembly, a friction brake assembly, and a resistance adjustment 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.
