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 exercise apparatus includes a support frame unit, a crank wheel unit disposed on the support frame unit, a resistance unit for providing resistance to the crank wheel unit, and two link units respectively disposed on left and right sides of the support frame unit. Each link unit includes a first pivot arm pivotally connected to the support frame unit, a pedal rod pivotally connected to the first pivot arm, a second pivot arm pivotally connected between the support frame unit and the pedal rod, a drive rod pivotally connected between the first pivot arm and the crank wheel unit, and a foot plate disposed on the pedal rod.

A stationary exercise apparatus includes a frame; two moving members respectively coupled to the frame, one end portion of each moving member located to define a swing axis; two swing members, one end portion of each swing member pivotally joined to the swing axis of the moving members; two supporting members respectively connected to the swing members, wherein one end portion of each supporting member is movably coupled to the frame, the other end portion of each supporting member is joined to the respective swing member so that one end portion of each supporting member moves along a reciprocating path; and two pedal sets respectively coupled to the supporting members, the pedal sets moving along a first path while the one end portions of the supporting members are reciprocating along the reciprocating path and the other end portions of the supporting members are rotating about a rotating axis.

An exercise device having a frame, first and second foot supports suspended on the frame by first and second linkage assemblies, one or the other or both of the frame linkage assemblies being interconnected to an adjustment device that is selectively adjustable by a user to select one of a plurality of discrete segments of a master or overall path of arcuate travel and to a lateral adjustment device that enables the user to selectively adjust a path of travel of the foot supports a selected angle relative to a central axis of the exercise device.

An exercise device including a frame with a first crank assembly rotatably coupled to the frame about a first axis and a second crank assembly rotatably coupled to the frame about a second axis. A control system may be used in communication with the first crank assembly and the second crank assembly, which may provide a synchronous movement of the first crank assembly relative to the second crank assembly. A pedal arm may be provided with a first end pivotally coupled to the first crank assembly and a pedal positioned on a second end. A crank link may be used with one end coupled to the second crank assembly and a second end coupled to the pedal arm. The crank link may be movable on the pedal arm which may provide varying paths of motion of the pedals.

An exercise device for performing a variety of movement patterns. The exercise device has a pair of linkages, each including an upper link pivotally mounted to a frame and a lower link pivotally coupled to an upper link. A foot support is provided on a distal end of each lower link. A compression link interconnects the lower link to the frame. The compression link includes a shaft coupled to the lower link, a sleeve coupled to the frame and a spring captured between the shaft and the sleeve, whereby the spring provides a resistance to movement of the lower link relative to the frame.

An exercise apparatus comprising a foot support movable by the user on the frame back and forth through any one of a plurality of complete, reproducible and different arc segments of a master arcuate path, the foot support being interconnected to an arc segment selection device that is manually actuatable to enable the user to manually select any one of the plurality of different arc segments, the foot support being interconnected to an arm having a handle manually graspable by the user to reduce or increase power or energy required by the user to move the foot support.

An exercise apparatus includes a frame body, two driving levers, two pedals, a linking device and at least one resistance device. The driving levers are pivotally connected to two side frames of the frame body, respectively. The pedals are connected to the two driving levers, respectively. The linking device is connected the driving levers so as to lead the driving levers to be swung reciprocally and simultaneously. The resistance device is driven by one of the driving levers so as to generate a magnetic resistance.

An exercise machine with a more natural gait which, in some embodiments, further allows for a variable stride length while in use. In one configuration, each side of the exercise machine has a first crank assembly connected at an upper location on a pedal arm and a second crank connected at a middle location on the pedal arm, and a pedal is attached to a lower location of the pedal arm. The first crank assembly is connected to the pedal arm by a crank arm. The second crank assembly is connected to the pedal arm via a crank arm pivotally attached to a crank link. The path of each pedal is determined by the lengths of crank arms and crank links of the first and second crank assemblies rotating in synchronous motion.
