A method and device for controlling the magnetic resistance of an exercise bike, and an exercise bike are provided. The method for controlling magnetic resistance of an exercise bike includes: monitoring in real time a working state of an electromagnet, and judging by a control module whether a resistance provided by a magnetron wheel conforms to a currently set resistance, according to a monitoring result of the working state of the electromagnet and a relationship between the working state of the electromagnet and the resistance provided by the magnetron wheel; and the control module adjusting a working current of the electromagnet if the resistance provided by the magnetron wheel does not conform to the currently set resistance, to adjust a magnetic field strength of the electromagnet, so that the resistance provided by the magnetron wheel conforms to the currently set resistance.

The present disclosure describes a new kind of portable hangboard intended for finger strength exercises. It allows the user to adjust the angle of the hangboard and the depth of the finger slot to control the difficulty of the exercise. The main body of the hangboard hangs on a rope. The main body of the hangboard contains multiple slots that the rope can pass through to adjust the angle of the device. The finger slot contained in the main body has magnets at the deep end which allow one or more shims with built in magnets to be inserted to make the slot shallower. The hangboard offers greater portability and variety of exercises compared to other inventions of this class.

A sports and performance media positional detection system, comprising: at least two elements, with at least one element involved in the sporting activity; a power source; and machine-to-machine communication, which are collectively arranged such that if any two or more elements interact, their electromagnetic properties can be detected thus allowing the position of the interacting elements to be communicated to a decision maker. The system can be applied to at least one stationary element, which can be the playing surface, lines defining the boundaries, or a set of goalposts; and at least one moving element, which could be a ball, footwear, or the participants themselves. The system can also be applied to performance media capture.

A tethered ring toss game apparatus is provided. In some embodiments, the apparatus may include a target device having a target body, a first bar target, a second bar target, a first hook target, and a second hook target. The first bar target and second bar target may be positioned on opposite sides of the target body, and the first hook target and second hook target may be positioned on opposite sides of the target body. A ring having a ring aperture may be coupled to a first end of a flexible tether, and a second end of the flexible tether may be positioned between 28 and 38 degrees above the target device. The flexible tether may have a length that enables the ring aperture of the ring to be alternatively positioned around each of the first bar target, second bar target, first hook target, and second hook target.

A balance board system, comprising, a rotatable roller, a balance board having a lower surface that sits atop the rotatable roller and reciprocally rides on the rotatable roller, the balance board lower surface having a plurality of attachment points, a plurality of board connectors disposed at the plurality of attachment points, a plurality of stop connectors and a plurality of roller stops coupled to at least two of the plurality of stop connectors, the plurality of roller stops are attachable to the balance board at a respective one of the plurality of attachment points.

A sensing base for an adjustable free weight may include a cradle, and a sensing assembly, which includes a plurality of sensors and mechanical components (e.g., pivoting levers), each associated with a respective plate well that accommodates a weight plate of the adjustable free weight such that each mechanical component actuates the state of a respective sensor upon placement or removal of the weight in a plate well. Sensor signals reflecting the states of the sensors are communicated, via a circuit, a processor to determine the weight selection of the adjustable free weight when removed from the base. The sensing assembly may be implemented using individual sensors of a variety of different types such as hall effect sensors, optical interrupt sensors, IR optical sensors, and the like. The base may be configured to automatically communicate the determined weight to an external computing device to facilitate activity tracking and/or fitness coaching.

The present disclosure provides a golf club and golf club head which integrate a bottle opener mechanism onto a rear wall of the head so as to provide bottle cap removal functionality without interfering with the shape that allows players to scoop balls from the ground without bending down. The golf club head may also have a permanent magnet disposed adjacent to the bottle opener mechanism to prevent removed bottle caps from falling to the ground.

Disclosed herein is an accessory pouch for golf for accommodating a golf accessory. The accessory pouch includes: a pouch body formed in an openable container, and configured to provide an accommodation space for a golf accessory; at least one magnet provided on one surface of the pouch body, and configured to detachably attach the pouch body to a metal plate while providing a magnetic force; and a magnet holder configured to fix the magnet to the one surface of the pouch body.

Apparatus, systems, and methods are provided for measuring and analyzing movements of a body and for communicating information related to such body movements over a network. In certain embodiments, a system gathers biometric and biomechanical data relating to positions, orientations, and movements of various body parts of a user performed during sports activities, physical rehabilitation, or military or law enforcement activities. The biometric and biomechanical data can be communicated to a local and/or remote interface, which uses digital performance assessment tools to provide a performance evaluation to the user. The performance evaluation may include a graphical representation (e.g., a video), statistical information, and/or a comparison to another user and/or instructor. In some embodiments, the biometric and biomechanical data is communicated wirelessly to one or more devices including a processor, display, and/or data storage medium for further analysis, archiving, and data mining. In some embodiments, the device includes a cellular telephone.

An apparatus includes a pair of support members, a cable, a rolling mechanism, a tackling bag and a pulley device. The pair of support members are fixedly coupled to a surface. The cable is attached to and extends between the pair of support members. The rolling mechanism is connected to the cable and configured to traverse the cable from a first end of the cable toward a second end of the cable. The tackling bag is attached to the rolling mechanism and configured to be propelled from one of the pair of support members toward the other of the pair of support members. The cable passes through a pulley system which is couple to a stack of weights. When the tackling bag is tackled, the stack of weights provide resistance to the tackler.
