A stationary exercise machine in accordance with some examples herein may include a frame, a crankshaft rotatably supported by the frame, an upper moment-producing mechanism and a lower moment-producing mechanism both operatively engaged to the crankshaft to cause the crankshaft to rotate. The lower moment-producing mechanism and the upper moment-producing mechanism may be resiliently coupled to one another, such as via a resilient coupling between a crank arm of the lower moment-producing mechanism and a link or virtual crank arm or the upper moment-producing mechanism. The exercise machine may further include a measurement apparatus which may be configured to measure differential forces between the upper and lower mechanisms.

A training bicycle, including a first frame (1, 36) configured to be supported on a floor, a second frame (2, 37) connected to the first frame, the second frame including an axle (4) allowing the second frame to tilt relative to the first frame along an axis in the longitudinal direction of the training apparatus, a handlebar (12, 35, 77, 90) connected to the upper end of a steering shaft (11, 76), the steering shaft being rotationally connected to the second frame, a crank (26, 110) connected to the second frame, and a first flywheel (22, 41, 56, 167, 193) rotationally connected to the lower end of said steering shaft with means for transferring movement from the crank to the first flywheel.

A platform for enabling omnidirectional movement of an exercising machine is disclosed. The platform may comprise a hemispherical inner body comprising a hollow cavity. The hollow cavity may be used for accommodating an exercising machine into the hollow cavity. The exercising machine may be one of a treadmill, treadclimber, and bicycle. The platform may further comprise an outer body. The outer body may be rotatably engaged with the hemispherical inner body. The rotatable engagement may allow an omnidirectional movement of the hemispherical inner body in a horizontal plane and an inclination and declination of the exercising machine. The platform further comprises a communication unit. The communication unit may be connected with the hemispherical inner body for receiving user's inputs for movement. At least one of the hemispherical inner body and the exercising machine may move based on the user's inputs for movement. The platform may also find use in virtual shopping environments to help a user in buying products.

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.

Described herein are embodiments of stationary exercise machines having reciprocating foot and/or hand members, such as foot pedals that move in a closed loop path. Some embodiments can include reciprocating foot pedals that cause a user's feet to move along a closed loop path that is substantially inclined, such that the foot motion simulates a climbing motion more than a flat walking or running motion. Some embodiments can further include reciprocating handles that are configured to move in coordination with the foot via a linkage to a crank wheel also coupled to the foot pedals. Variable resistance can be provided via a rotating air-resistance based mechanism, via a magnetism based mechanism, and/or via other mechanisms, one or more of which can be rapidly adjustable while the user is using the machine.

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.

The present invention relates to a manually operated treadmill adapted to generate electrical power comprising a treadmill frame, a running belt supported upon the treadmill frame and adapted for manual rotation, and an electrical power generator mechanically interconnected to the running belt and adapted to convert the manual rotational motion of the running belt into electrical power.

A machine for concurrently performing opposing pushing and pulling motions with the legs and arms at various angles to simulate multiple exercises including climbing, running and crawling motions, wherein the machine is adjustable in angle. The individual lower body user supports move in a back and forth pattern on rails and include foot platforms and shin support pads for support a user's lower body and pivoting upper body user support hand grips wherein the left upper body user support and left lower body user support move in opposite directions and the right upper body user support and right lower body user support move in opposite directions and all four user supports move in unison.
