A variable-resistance exercise machine with wireless communication for smart device control and interactive software applications, comprising a wireless 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.

There is a first and second set of right and left dual link members. The first set of right and left link members connected with an axis, axle in a frame. The second set of right and left link members connected with the first set of left and right link members and these connections are located radial from the axis axle in the frame. These connections between the first and second link members of the right and left side are configured at 180 degrees relative to each other. Foot supports connected with the second set of crank arms and located longitudinal from the connection in-between the first and second crank arms. The second set of crank arms may swing, rotate move one way forward as the first set of crank arms rotates forward 360 degrees allowing the user a more natural moving style and running motion, defined as run-cycling.

A reciprocating rehabilitation device that can be used as a stand alone unit or incorporated within a stationary bicycle. The device utilizes independently operating pedals together with range of motion limiters. Patients and therapists alike can rehab each limb independently through any necessary progressive range of motion on the way to recovery.

A procedure and apparatus to determine the overall fitness of a test subject. For this purpose the qualitative and temporal progression of the heart rate under constant physical stress of the subject is prescribed with at least one parameter dependent on the subject. The heart rate of the subject is measured under constant physical stress during a period of time. The parameter(s) are determined from the measured values, and the maximum heart rate and/or the initial heart rate and/or the increase characteristic of the heart rate are determined from the function and the measured values by numerical procedures. The apparatus can measure the heart rate of the subject, record a temporal progression of the heart rate under physical stress, and determines numerically from the temporal progression of the heart rate, the maximum heart rate and/or the initial heart rate without physical stress and/or the increase characteristic of the heart rate.

An exercise apparatus having a cabinet housing to which a telescopically and angularly moveable arm is mounted. A hand pedal assembly is mounted to the arm and drivingly linked to a resistance mechanism. A platform is telescopically mounted to the bottom of the cabinet, and a foot pedal assembly is adjustably mounted to the platform. A seat is mounted to the far end of the platform from the cabinet, and the platform can be moved so the seat, the foot pedal assembly, or at least portions of both, can be inserted into a chamber of the cabinet.
