The present invention provides means capable of detecting a force acting on an upper part of an endless belt of the treadmill from a subject on the upper part of the belt even in a treadmill in which the height of a lower space below the upper part of the endless belt is limited. A treadmill comprises an endless belt 6 entrained about a front roller 4 and a rear roller 5 and a support plate 3 provided below an upper part 60 of the endless belt 6 and on which the upper part 60 of the endless belt 6 runs. The support plate 3 comprises a plurality of piezoelectric elements P inside the support plate 3 and/or on a surface of the support plate 3 so as to detect a force acting on the support plate 3 from the upper part 60 of the endless belt 6.

Systems and methods for integrating and using sensor system in articles of apparel are provided. The system may include an apparel piece sized and dimensioned to be worn on a user and a sensor system integrated with the apparel piece. The sensor system may include at least one stretchable capacitive sensor positioned on the apparel piece so as to measure a biometric parameter of the user when the apparel piece is worn, an illumination system configured to provide illumination in a specified illumination area based on the measured biometric parameter of the user, and a control module to control one or more settings of the illumination system.

A balance training method using a wearable device, and the wearable device are disclosed. The balance training method using the wearable device configured to provide a walking assist function includes executing a balance training mode of the wearable device and supplying an irregular pattern torque to an actuator of the wearable device at a time point or in a time period in the balance training mode.

A method for displaying archived exercise classes includes displaying information about archived exercise classes that can be accessed by a first user via a computer network on a display screen at a first location such that the first user can select among a plurality of archived classes, outputting digital video and audio content including the selected archived class, detecting a performance parameter for the first user at a particular point in the selected class, displaying the performance parameter on the display screen, and displaying performance parameters from a second user at a second location on the display screen such that at least one of the performance parameters from the first user and at least one of the performance parameters from the second user at the same point in the class are presented for comparison.

Disclosed are various embodiments directed toward applying a magnetic resistance to a human powered vehicle during movement. In various embodiments, magnets are placed within receptacles of magnet holding brackets and are exposed to one or more conducting discs that are configured to spin with the wheels of the human powered vehicle. The magnetic field of the magnets that intersect the conducting discs can generate a force that opposes the movement of the human powered vehicle. In various embodiments, the magnet holding brackets are adjustable based on desired wattage values.

Stationary exercise machine configured to execute a programmed workout with aerobic portions and lifting portions. In one embodiment, a stationary exercise machine may include an aerobic exercise element configured to be movable during execution of a programmed workout, a display, one or more processors, and memory. The memory may be configured to store programmed instructions of the programmed workout that, when executed by the one or more processors, cause the one or more processors to: automatically alternate, by the programmed instructions of the programmed workout, between aerobic portions and lifting portions, automatically control, by the programmed instructions of the programmed workout, a speed, or a resistance level, of the aerobic exercise element during the aerobic portions, automatically present, by the programmed instructions of the programmed workout, lifting instructions on the display, the lifting instructions configured to instruct a user on lifting one or more free weights during the lifting portions.

A treadmill is provided according to various embodiments. The treadmill includes a first rotatable element coupled to the frame; a second rotatable element coupled to the frame; an intermediate member coupled to the frame that is disposed intermediate the first rotatable element and the second rotatable element and coupled to at least one of the first rotatable element and the second rotatable element; a running belt disposed about the first and second rotatable elements, the running belt defining a non-planar surface; and a safety device coupled to the intermediate member. The safety device is operable to substantially prevent rotation of 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.

An exercise machine accessory is disclosed. In one embodiment, a resistance identifier is configured to identify resistance for an exercise machine associated with the exercise machine accessory, wherein the resistance identifier is coupled to the exercise machine. In one embodiment, a motion identifier is configured to identify exercise motion for a user of the exercise machine. In one embodiment, a communications module is configured to communicate with the user of the exercise machine, wherein the communications module is coupled to the resistance identifier and the motion identifier.

An impact detection device includes a sensor that is attached to sports equipment including a columnar portion and a hitting portion connected to the columnar portion and is attached not at the hitting portion but at the columnar portion, and that is configured to output a sensor signal obtained by the sports equipment being swung, and a feature data extraction unit configured to detect, by using the sensor signal, from a temporal change of the sensor signal outputted by the hitting portion externally receiving pressure, timing at which the hitting portion externally receives the pressure.

An exercise device comprising a bendable pole with spring-like properties. The bendable pole has grips at opposing ends and in a midsection. The exercise device is configured to be used for a variety of exercise methods. The exercise device provides personal fitness tracking in conjunction with a mobile software application.
