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 machine with a more natural gait and computer gaming interface 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.

An exercise device with a pair of upper links coupled to a frame and a pair of lower links pivotally and respectively coupled to the upper links is provided. A pedal 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 respective upper link and a second end opposite to the first end. A first and a second damper arm, each pivotally coupled to the frame, may be included, each damper arm receiving a respective pushrod. An actuator may be coupled to the first damper arm and the second damper arm, thus providing movement of the first and second pushrods to alter a resting position of the first and second upper leg links with respect to the frame.

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 transfer system is coupled to the frame and both upper links for transferring both tensile and compressive forces. Separate torque elements are operably coupled to the frame and each lower link via a transfer member for independently resisting movement of the associated lower link.

An exercise device has guide links each having a first attachment point pivotally attached to an upper part of a frame. Foot support links each have a foot receiving area to support a user's foot and are pivotally connected to a second attachment point of one of the guide links so that when the guide links pivot relative to the frame, the foot support links move in a path of travel having a horizontal component of motion. A first and a second control pulley are each pivotally connected to a respective one of the guide links and offset from the first pivot axis so as to move in an arc. A first and a second flexible element each couple the vertical drive assembly to a respective one of the foot support links. Each flexible element has a midportion extending about a respective one of the control pulleys.

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 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.

A direction-reversing device includes a frame, two side wheels, a reverse wheel module, a flexible member and a tension adjusting mechanism. The side wheels are pivotally disposed on two side of the frame, respectively. The reverse wheel module disposed at the frame includes two reverse wheels. The reverse wheels are coaxially disposed to the frame and perpendicular to the side wheels. The flexible member is wound around the side wheels and the reverse wheels. The tension adjusting mechanism disposed at the frame includes at least one fastener. The fastener connecting the reverse wheel module to the frame is for changing a relative position between the frame and the reverse wheel module. Therefore, a tension of the flexible member is changed accordingly.

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.
