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.

It is provided an apparatus for training a person's lower and/or upper extremities, comprising at least two motion elements which are arranged on a base element, wherein the motion elements each have an axis of rotation around which an actuating element can be moved. The motion elements each are independently movable relative to the base element about a first axis of movement, wherein the first axis of movement extends substantially perpendicular to an extension surface of the base element. Each motion element has a separate drive in order to rotate the actuating elements about the axis of rotation, and that the apparatus includes a control element which can individually actuate each drive in order to provide for a movement of each drive independent of a movement of another drive.

A reversible resistance exercise machine for reversing the direction of applied resistance against a movable platform of an exercising machine. The exercise machine has a frame, a carriage movably positioned upon the frame, and a plurality of biasing members. A plurality of first tension connectors are accessible near the first end of the carriage and are adapted for removably attaching selected biasing members near the first end of the carriage to resist motion of the carriage in the first direction. A plurality of second tension connectors are accessible near the second end of the carriage and are adapted for removably attaching selected biasing members near the second end of the carriage to resist motion of the carriage in the second direction. A user selectable amount of force may be applied to the carriage to resist movement in either of the first direction and the second direction.

The present application relates to a fitness apparatus having a housing on which are arranged a first supporting element and also a second supporting element. The first and the second supporting elements can be moved linearly in each case in two spatial dimensions located at right angles to one another. The housing has at least one active element, by means of which a movement of the first supporting element or of the second supporting element out of a respective starting position is counteracted by a force. The housing also has at least one coupling element, which couples the linear movement of the first supporting element in a first direction of a first of the two spatial dimensions to a linear movement of the second supporting element in the second direction, which opposes the first direction in this first of the two spatial dimensions.

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.

An exercise machine reversible resistance system for reversing the directional force of resistance against an exercise implement before, during, or after the performance of a routine of one or more exercises. The exercise machine reversible resistance system generally includes a frame, an elongated member movably positioned upon the frame, wherein the elongated member has a first run and a second run, a resistance device that applies a resistance force to the elongated member in a single direction, an exercise implement movably connected to the frame and a clutch connected to the exercise implement. The clutch is adapted to selectively engage the first run or the second run of the elongated member for selective control of the resistance direction of the exercise implement.

An exercise machine with electromagnetic resistance selection for changing exercise resistance settings by engaging more or fewer resistance biasing members using a electromagnets. An example implementation includes a movable carriage configured to move substantially along the length of one or more rails. A plurality of resistance biasing members are removably attachable between a stationary biasing member bracket affixed to the machine structure and the movable carriage. A controller changes the resistance settings against the movable carriage by electrically attaching or detaching any preferred number of resistance biasing members between the machine structure and movable carriage.

A body weight exercise device includes a frame, a first handle attached to the frame, a second handle attached to the frame, and a processor and memory. The memory includes programmed instructions to cause the processor to determine a characteristic associated with a performance of an exercise with the body weight exercise device.

A treadmill includes an opening formed in a surface of a running deck, a resistance mechanism incorporated into the running deck, and a cable threaded through the opening, where the cable includes a resistance end connected to the resistance mechanism and a pull end accessible through the running deck.

The present invention extends to a re-configurable multi-purpose exercise device. In general, aspects include a re-configurable multi-purpose exercise device that can be configured as an abdominal roller, a pair of pushup stands, or a jump rope. Some aspects include a first roller and a second roller that can attach to one another by mating extending members formed on each respective roller with slots formed on each respective roller. A first handle and a second handle can attach to one or another of the respective rollers by either attaching to the extending members on the rollers or inserting through a hole formed in the rollers. A rope can connect on each end to the first handle and the second handle to form a jump rope. Additionally, some aspects include a two-piece cavity configured for storing the rope.
