Ergonomics improvement systems having wearable sensors and related methods. An example ergonomics improvement system includes an encoder system to couple to a limb of a body. The encoder sensor system to generate first outputs in response to movement of the limb relative to the body to determine a position of the limb relative to the body. The system includes a load sensor to generate a second output representative of a load carried by the body and a position sensor to generate a third output representative of a position of a right foot of the body relative to a position of a left foot of the body.

An exercise machine is for performing a striding exercise motion. The exercise machine has frame; first and second pedal members; first and second foot pads on the first and second pedal members, respectively, each of the first and second foot pads being configured to move in an elliptical path during the striding exercise motion; first and second rocker arms pivotally coupled to the frame; and first and second adjustment devices configured to actively adjust and set a position of the first and second pedal members relative to the first and second rocker arms, respectively, which thereby changes a shape of the elliptical path.

A rowing machine exercise device includes a vertically adjustable rear support base. The vertically adjustable rear support base includes an outer vertical support beam coupled to and extending down from the rowing machine frame, where the outer vertical support beam has a vertical channel extending upward therein from a bottom of the outer vertical support beam and has a latch pin hole extending through a wall of a bottom portion of the vertical support beam; an inner vertical support beam received in a telescoping manner within the outer support beam through the bottom of the outer support beam, where the inner vertical support beam has a plurality of adjustment holes uniformly spaced along a vertical line in an outer wall of the inner vertical support beam.

An exercise machine with adjustable handles that provide for multiple handle positions. The exercise machine with adjustable handles generally includes a frame with one or more rails, a carriage movably positioned upon the rails, and a pair of adjustable handles positioned near an end of the frame. The adjustable handles each have a handle portion that is movably connected to a corresponding handle stanchion to pivot from a storage position to an extended position.

Various embodiments related to a recumbent therapeutic and exercise device are provided herein. The recumbent therapeutic and exercise device includes a frame; a hand crank system coupled to the frame, the hand crank system including a hand crank rotatable by a user, wherein the hand crank is movable in a substantially vertical plane closer to and further from a support surface for the frame; and a foot crank system coupled to the frame, the foot crank system including a foot crank rotatable by the user, wherein the foot crank is movable in a substantially horizontal plane relative to the support surface for the fame.

A stationary exercise device having variable footpaths is disclosed. The exercise device includes a frame, a pair of supporting members that have a first end to rotate about an axis and a second end to move along a reciprocating path, a pair of pedals joined to the supporting members, and a guider assembly for adjusting an incline angle of the reciprocating path.

A stationary exercise machine according to the present disclosure may include a frame, a crankshaft rotatably supported by the frame, first and second lower linkages, and first and second crank arms connected to opposite sides of the crankshaft such that rotation of either of the crank arms causes rotation of the crankshaft. The lower linkages may be operatively connected to the crankshaft and to a respective one of first and second pedals. Each of the lower linkages may include a reciprocating member operatively connecting one of the pedals with one of the crank arms. Each of the lower linkages may include an adjustable linkage connected between the reciprocating member and the respective crank arm, the adjustable linkage may vary a distance between an output end of the reciprocating member and an input end of the crank arm. Each of the pedals may be pivotally connected to the respective reciprocating members.

A system may include a receiving module and a conversion module. The receiving module may be for receiving location data associating video data depicting a real-world route with topographical location of the real-world route. The conversion module may be for creating an exercise program. The exercise program could include control signals representing changes to be made to one or more operating parameters of an exercise device as the video data depicting the real-world route is displayed to a user of the exercise device. The control signals may be based at least in part on the location data. The changes to the one or more operating parameters may correspond at least in part to one or more aspects of the real-world route.
