Exercise apparatus (10) has two wheels (12, 12) rotatably mounted to a base 14, 14, spaced apart and each located within a housing (15, 15) respectively. Pivotably connected to the wheel is a cam (16). The other end of 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). Housing (20) is pivotably mounted to the arm (16) such that movement of the arm in a vertical plane up or down by operating on the handle causes an elliptical rotation of the arm relative to the wheel (12).

An exercise device having (-) a frame, (-) left and right leg linkages, each including (i) an upper leg member pivotally coupled to the frame for pivoting about an upper pivot point with the upper pivot point of each leg linkage defining a point on a laterally extending upper pivot axis that passes through the upper pivot point of each leg linkage, and (ii) a lower leg member directly pivotally coupled to the upper leg member distal to the upper pivot point for pivoting about a lower pivot point, and (-) a foot support attached to each lower leg member distal to each respective lower pivot point. The invention characterized by an ergonomically synergistic spatial orientation and relationship amongst and between the upper leg members, lower leg members, upper pivot axis, lower pivot axis, hip region of a user, knees of a user, a biased damping means in communication with the lower leg members, and an interconnect member interconnecting the lower leg links with and the biased damping means.

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.

A stationary exercise apparatus includes a frame; two moving members respectively coupled to the frame, one end portions of the moving members located to define a swing axis; two swing members, one end portions of the swing members respectively pivotally joined to the swing axis of the moving members; two supporting members respectively connected to the swing members, wherein one end portions of the supporting members are movably coupled to the frame, the other end portions of the supporting members are respectively joined to the swing members so that one end portions of the supporting members moving 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 with a pair of upper links coupled to the frame and a pair of lower links pivotally coupled to the upper links is provided. A pair of pedals is received on a distal end of each of the lower links. A transfer system between the pair of upper links may include a first and a second pushrod, each with a first end pivotally coupled to each upper link and a second end opposite to the first end. A first and a second pivot arm, each pivotally coupled to the frame, may be included, each pivot arm receiving a respective pushrod. A pliable connector may be coupled to the first pivot arm and the second pivot arm, thus providing compliant reciprocating movement of the upper links.

An exercise device comprising: a frame (10), first and second foot supports (24a, 24b) suspended on a frame (10) by first (18c, 26c, 26b) and second (18d, 26a, 26d) linkage assemblies, one or the other or both of the frame linkage assemblies being interconnected to an adjustment device (55, 56) that is selectively adjustable by a user to select one of a plurality of discrete segments (AP, P1, AP, P2) of a master or overall path of arcuate travel (J) and to a lateral adjustment device (58a, 58b) that enables the user to selectively adjust the path of travel of the foot supports a selected angle (8, 8) relative to a central axis of the 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 comprising: a frame having a generally vertical planar axis, first and second foot supports suspended on the frame by first and second linkage assemblies that are respectively arranged on the frame such that the first and second foot supports are pivotable through a front to back arcuate path of travel that is disposed at a selected angle between about five and about forty five degrees relative to the vertical planar axis.
