A therapeutic and exercise device includes a frame; a hand crank coupled to the frame which is rotatably movable by a user, the hand crank coupled to a vertically oriented rail such that the hand crank is adjustable in a vertical plane fore and aft relative to a support surface for the therapeutic and exercise device; a foot crank coupled to the frame which is rotatably movable by the user, the foot crank coupled to a horizontally oriented rail such that the foot crank is adjustable in a horizontal plane; and a brake coupled to the frame and to at least one of the hand crank or the foot crank, the brake configured to selectively apply a braking force to said at least one of the hand crank or the foot crank to resist rotational movement of the at least one of the hand crank or the foot crank.

A fitness equipment includes a main body, a binding structure and a support base. The main body is supported on the ground and includes a pedal unit. The binding structure is disposed on the main body. The support base is detachably pivoted to the binding structure and is rotatable correspondingly to the main body, wherein the support base includes a seat, a handlebar and a connecting structure. The handlebar is disposed on the seat. The connecting structure is disposed on the seat and detachably pivoted to the binding structure.

A human-powered generator includes a frame and a pedal crankset and crankset sprocket rotatably mounted on the frame, a flywheel rotatably mounted on the frame including a flywheel-crankset sprocket a flywheel-countershaft sprocket, a countershaft rotatably mounted on the frame including a countershaft-flywheel sprocket and a countershaft-alternator sprocket, and an alternator including an alternator drive shaft and an alternator sprocket. The human-powered generator also includes a crankset-flywheel drive chain, a flywheel-countershaft drive chain, and a countershaft-alternator drive chain. A pedaling cadence at the pedal crankset of between approximately 60 RPM and approximately 100 RPM achieves an alternator drive shaft RPM of between approximately 2,000 RPM and approximately 5,000 RPM.

An inclinable recumbent exercise device includes a rigid support base having front and rear portions, and extending along a plane from the front portion to the rear portion; a seat engaged with the base at the rear portion; a kinetic element engaged with the support base, and having first and second moveable leg engagement elements; and a fulcrum element positioned below the base. The base is pivotal about the fulcrum element from a first base position, in which the kinetic element is at an initial position, to a second base position, in which the kinetic element is at a subsequent position above the initial position and the seat.

An exercise apparatus including a stationary exercise apparatus and a lever arm pivotably biased about a pivot axis. A support supports the lever arm above the stationary exercise apparatus, and a biasing device rotatably biases the lever arm with respect to the support about the pivot axis. The pivot axis extends substantially in a vertical direction, and the stationary exercise apparatus is a treadmill.

An exercise and rehabilitation apparatus for exercising an extremity of a user. The apparatus includes a flywheel having a first side and a second side with a channel in the first side. The channel has a top edge near a planer surface of the first side. A lever, such as a pedal or handle, is adjustable in position and combined with an adjustment member. The adjustment member is movable within the channel between first and second positions. However, the adjustment member cannot be removed from the channel through a slot along the top edge. A locking pin, biased in an extended position, is combined with the adjustment member and is movable between the extended position and a retracted position. The flywheel includes a plurality of openings adapted to receive the locking pin in the extended position in order to secure the adjustment member at a particular location within the channel.

A vehicle seat assembly includes a seat base, a seat back rotatably connected to the seat base, a seat bottom mounted on the seat base, and at least one of the following mounted to one of the seat base, seat back, and seat bottom: a resistance mechanism structured to exert a biasing force on at least one exercise arm operatively connected to the resistance mechanism; a bicycle seat receptacle structured for detachably mounting a bicycle seat to the seat base; and a docking mechanism structured for detachably mounting a pedal mechanism to the seat base.

An orthotic foot rest is a pedal for a pedaling machine. It includes a platform, an instep-strap and/or a heel strap and a width-adjusting assembly. The platform holds a person's foot that is either bare or in a shoe. When present, the instep-strap forms an arch extending up above the platform such that the person's foot, with or without a shoe, can be slipped under the arch and rest on the platform. When present, the heel strap encircles the person's foot. A width-adjusting assembly adjusts the tension against the side of the foot to secure it in place on the platform. Paired-strap-posts define a u-shaped-slot between them that is wide enough to receive the strap and restrain a cam buckle that is slidably attachable on each of the straps. A release strap enables a person to pull on the release-strap to remove the buckle from the u-shaped-slot.

A variable-resistance exercise machine with communication for smart device control and interactive software applications, comprising a network interface that receives input from a user device and provides output to a user device; a plurality of moving surfaces that each provide an independent degree of resistance to movement based on received input and that detect movement and provide output to a user device based on the movement; and a plurality of rigid rails that provide a rigid support for a human user to grasp, and that provide attachment points for a user to affix a variety of devices.
