A manually powered treadmill includes a frame; a first rotatable element coupled to the frame; a second rotatable element coupled to the frame; a plurality of bearings coupled to the frame; a running belt at least partly supported by the plurality of bearings, where at least a portion of the running belt defines a curved running surface; and a safety device coupled to at least one of the first rotatable element and the second rotatable element. The safety device is structured to substantially prevent rotation of the at least one of the first rotatable element and the second rotatable element in a first rotational direction and permit rotation of the at least one of the first rotatable element and the second rotatable element in a second rotational direction opposite the first rotational direction.

A folding exercise bike can be easily assembled and disassembled/folded for storage and/or transportation. The exercise bike can include a telescoping seat, a telescoping stem, a fold to stow handlebar and fold down locking legs. Various configurations for the exercise bike can be used. The exercise bike can include a wireless transmitter to transmit cycling data to a user's portable electronic device.

This present invention relates to an E-bike built for daily commuting with a special software allowing the E-bike to be converted into a high-end smart trainer using the regenerative brake torque as a resistance in order to work out and recharge the battery. The software/application allows to control the resistance in real time and read all the data in order to create a custom workout routine while charging the battery. The E-bike can be connected to third party virtual cycling software through the ANT+ protocol to maximize the potential.

A treadmill includes a treadmill frame having a front end and a rear end opposite the front end; a pulley coupled to the treadmill frame; a running belt disposed about the pulley, the running belt defining a non-planar running surface; a motion restricting element coupled to the frame and configured to limit rotation of the pulley to only one rotational direction; and a brake coupled to the running belt and adapted to selectively restrict the speed of rotation of the running belt depending upon an established limit for a speed of the running belt.

This disclosure provides systems, methods, and apparatus for enabling exercise by a user. In one aspect, an apparatus includes a communication unit, a user interface unit, and a processor. The processor may receive user identification data from the user via the user interface unit and retrieve data based on the user identification data from an electronic data store. The processor may use the data to generate an exercise routine and command signals may be sent to an exercise machine based on the generated exercise routine. The processor may receive exercise data from the exercise machine via the communication unit and store the exercise data in the electronic data store.

An exercise machine includes a cyclical actuator and a mechanical energy storage device. Connective structure operatively connects the cyclical actuator to the mechanical energy storage device. Motion of the cyclical actuator urges physical motion of and energy storage in the mechanical energy storage device. The exercise machine further includes an electric machine. A communication pathway enables exchange of data between multiple associated exercise machines such that multiple associated operators on multiple associated exercise machines have a common experience.

An exercise apparatus having a pulley, a pair of stabilizing assemblies each configured to couple a front portion of a respective pedal element to each side of the pulley, a looped belt configured to couple the pulley to a resistance assembly, a tension stabilizer configured to maintain a tension of the looped belt on the pulley, and the resistance assembly configured to assert an adjustable resistance to the pedal elements through the looped belt. The exercise apparatus also comprises a transport mechanism with a handle for transporting the exercise apparatus.

A motor-less leg-powered curved treadmill produced that allows people to walk, jog, run, and sprint without making any adjustments to the treadmill other than shifting the user's center of gravity forward and backwards. A closed loop treadmill belt running between front and rear pulley rollers is formed with a low friction running surface of transverse aluminum, wooden, plastic, rubber or carbon fiber slats attached to each other in a resilient fashion. An essential feature of treadmill is the concave shape of the upper portion of the belt running surface, the treadmill configurations ensure that this shape is maintained during actual use. These configurations prevent the concave upper running surface portion from being pulled taut into a flat shape between the front and rear pulley rollers. The slats of the treadmill each have an end view crossectional I-beam shape, for strength and stability of the slat positioned upon the treadmill belt.

A strength and endurance training system. The system includes a first assist-resist system, which includes a first motor that is activated and deactivated by a first motor controller, a first drum coupled to the first motor, a first connecting member provided between the first drum and a coupling device which is attachable to an object/individual, and a computer system configured to use as input one or more of i) a measurement of distance of the coupling device form the first assist-resist system, ii) a predetermined strength value, and iii) a measurement of external force applied to the coupling device by the individual and thus operate the first assist-resist system in one of i) a resistive mode, wherein a resistive force is applied to the coupling device when the coupling device moves away from the first assist-resist system, ii) an assistive mode, wherein an assistive force is applied to the coupling device when the coupling device moves towards the first assist-resist system, and iii) a bypass mode, wherein a negligible force (between about 0 N-about 5 N) is applied to the coupling device.
