A linkage mechanism with an elliptical motion trajectory includes a main body having two guiding tracks with a changeable lifting angle, a flywheel assembly and two handles installed on a front side of the main body, a first linkage rod pivotally attached between guiding rods of two driving linkage assemblies and two cranks of the flywheel assembly. The two pedals respectively include a front end pivotally attached onto each one of the cranks. Each one of the pedals moves together each one of the guiding rods and along each one of the guiding tracks and drives the flywheel assembly and each one of the handles to move forward and backward.

A modular exercise apparatus comprising a frame, a common drivetrain supported by the frame and including a common axle, a plurality of input receivers coupled to the common axle, and a resistance member operably coupled to the common axle and operable to provide resistance against rotation of the common axle, a first exercise attachment including a first drive member operably coupled to a first input receiver of the plurality of input receivers of the common drivetrain, and a second exercise attachment including a second drive member operably coupled to a second input receiver of the plurality of input receivers of the common drivetrain.

An exercise apparatus (10) has two wheels (12, 12′) rotatably mounted to a base (14, 14′), spaced apart and each located within a pair of wheel housings (15, 15′), respectively. Pivotably connected to each wheel is a cam (16). Another end of the cam (16) is pivotably connected to a push rod (17) which is pivotably connected to a handle (18) which is rotatably mounted in a housing (20). The pair of handle housings (20) are pivotably and respectively mounted to the pair of cams (16) such that movement of each arm in a vertical plane up or down by operating on the respective handle causes an elliptical rotation of the respective cam relative to the respective wheel (12, 12′).

An elliptical exercise machine may include a base, one or more upright stanchions coupled to the base and extending upward from the base and supporting first and second cranks. The first crank may support a first crank arm. The first crank arm may support a first pedal leg hanging downward from the first crank arm. The first pedal leg may support a right pedal. The right pedal may be configured to swing forward and rearward and to raise upward and lower downward. The second crank may support a second crank arm. The second crank arm may support a second pedal leg hanging downward from the second crank arm. The second pedal leg may support a left pedal. The left pedal may be configured to swing forward and rearward and to raise upward and lower downward.

An elliptical trainer includes a machine table, a transmission unit, two pedal units and two suspension arms. Each pedal unit has a pedal rod and a guide. The pedal rod has a front end thereof pivoted to one respective crank arm, and an opposing rear end thereof pivoted to one respective pedal seat. The pedal seat has the top surface thereof bearing one respective pedal. Each suspension arm has two opposite ends of a bottom side thereof respectively pivoted to the machine table and the rear end of one respective pedal rod. Each suspension arm is skewed in the direction of the pedal, so that each suspension arm can guide the pedal forward along a straight line direction and backward along a diagonal direction.

A stationary exercise apparatus includes two connecting members each having an upper end guided to move along a circular path and a lower end coupled to a swing member, so that when the upper end moves along the circular path, the lower end moves along an arc-shaped path. Two supporting members are configured to support a user's feet, which are coupled between the upper end and the lower end of the respective connecting members and movable along a closed path. Two control members each is arranged between the corresponding supporting member and the corresponding swing member for guiding the second portion of the corresponding supporting member along a predetermined path, so that an angle formed between each supporting member and the corresponding connecting member varies as the corresponding swing member moves along the arc-shaped path between a first endpoint and a second endpoint.

The subject matter of present disclosure teaches about a system of an artificial intelligence powered advance exercising facilities and method of working of the same. The system of an artificial intelligence powered advance exercising facilities of present embodiment eliminates need of permanent attached display over the exercise machines within the facilities by providing advance coupling of network enabled user devices of an exerciser, such as smartphone, laptop or any wearable smart devices to receive and display real time exercise data. Also, the system provides holding platforms for said user devices to safely hold the devices while user is exercising. Further, all the machines and equipment within the exercise facilities as well as surroundings such as wall of facilities of system are embedded with smart chips that monitors and transmits the real time exercise data of exerciser such as routine of exerciser, form and posture of exerciser, number of reps and count of dead weight etc. to the central artificial intelligence engine using local area network of exercise facility. The Artificial Intelligence engine, based on past exercise data, exercise regimen, health data and expert advices, prepares best workout routine and exercise schedule of the day for respective exerciser.

An exercise machine may include a stationary frame, an inclinable portion movably connected to the stationary frame, and an incline mechanism connected to the stationary frame. The incline mechanism may include a coiling mechanism, a coiling rod of the coiling mechanism, a flexible coiling link movable with a rotation of the coiling rod, and where the flexible coiling link is connected to the inclinable portion.

An apparatus for converting a cycle-type exercise machine into another type of exercise machine includes a stationary frame structure that attaches to a frame of the cycle-type exercise machine, a pair of swing arms pivotally coupled with the stationary frame structure, and a pair of coupler bars pivotally coupled with the pair of swing arms on one end and rotationally attached to a crank bar of the cycle-type exercise machine on an opposite end.

A media holder for an exercise machine in accordance with some examples herein may include a first portion, a second portion movable relative to the first portion; and a size adjustment mechanism movably connecting the second portion to the first portion to enable resizing of a media holding region independent of whether a media item is present in the media holding region. The size adjustment mechanism may include an arm pivotally coupled to the second portion and configured to selectively engage the first portion in a plurality of positions.
