System and techniques for tracking caloric expenditure using sensor driven fingerprints are described herein. A set of outputs may be obtained from a plurality of sensors. A fingerprint may be generated using the set of outputs. The fingerprint may correspond to an activity observed by the plurality of sensors. The generated fingerprint may be compared to a set of fingerprints stored in a database. Each fingerprint of the set of fingerprints may correspond to a respective caloric expenditure. A caloric expenditure may be calculated for the activity based on the comparison. An exercise profile of a user may be updated using the caloric expenditure

User interface elements relating to fitness may be shared between user devices. These user interface elements may be updated based at least in part on activity data of users associated with the user devices. A user may determine a length of time for sharing their user interface elements. Once a sharing relationship between at least two users has been established, updates corresponding to user interface elements may be shared between the users via their respective user devices.

An electric training apparatus is configured to apply, by a load motor, a load on a rotating body configured to apply a load on an exercising person, detect an exercise physiological response value of the exercising person and a number of revolutions of the rotating body, perform control for gradually increasing the load of the load motor toward a set load upper limit value so that a detection result of the exercise physiological response value of the exercising person approaches a target exercise physiological response value set in advance, and change, before an exercise or during the exercise by the exercising person, the load upper limit value in response to a control command input based on a state of the exercising person, a state of the control, and a perceived exertion scale for the exercising person.

Cycling training apparatus (1), comprising a structure (2) that is supported on the floor (151) and a belt (4) that is movable with respect to the structure (2) and forms a closed longitudinal loop on which a bicycle (100) can be supported and ridden, The apparatus (1) comprises a securing element (9; 29) with two opposite ends (10, 11; 30, 31). One end (10; 30) has a first connector (12; 32) configured to be attached to a bicycle (100). The opposite end (11; 31) includes a second connector (13, 33) configured to be attached to a fixed point, The securing element (9; 29) is flexible so that the straight line distance (D) between these ends (10, 11; 30, 31) is variable, enabling the bicycle (100) to move longitudinally over the belt (4). The connectors also allow for transversal movement and lateral tilting of the bicycle (100).

Implementations described and claimed herein provide systems, apparatuses, and methods for providing cardiovascular exercise by simulating an exercise experience, such as a jump rope experience. In one implementation, a pair of exercise simulators is provided. Each of the exercise simulators includes a spin assembly rotationally mounted to a handle along an axis line. The spin assembly is configured to rotate about the axis line. At least one weight is housed in the spin assembly, and a light source is configured to rotate about the axis line with the spin assembly. The light source is configured to emit light to provide a visual representation of the motion of the spin assembly.

An activity tracking racquet attachment device tracks activity such as calories burned over a period of using a racquet to which the device is attached. The device includes a housing having a first face and a perimeter sidewall extending from and around the first face. A processor is coupled to the housing. A motion detector is coupled to the housing such that the motion detector detects movement of the housing. The motion detector is communicatively coupled to the processor wherein the processor receives motion data from the motion detector. A coupler is coupled to and extends from a second face of the housing coupling the housing to an end of a handle of a racquet such that the first face of the housing faces outwardly from the end of the handle.

An adjustable barbell or dumbbell or exercise device includes a handle device having a handle bar engageable into grooves of a number of weight members, a number of plates disposed on the handle bar and engageable between the weight members, and the plates each include an engaging element for engaging with the weight members and for anchoring a selected number of weight members to the handle bar, and a detecting device is attached to the handle device and includes a weight detector connected to a processing unit for sending weighing signals to the processing unit, and a displayer for displaying a total weight of the handle device and the weight members.

A system and method for adaptive fitness testing is provided. A fitness testing application manages fitness tests on a fitness testing apparatus by collecting physiological data and calculating various performance metrics. The fitness testing application automatically reconfigures fitness tests to adopt to a user's improving fitness level.

Resistance mechanism and method for an exercise cycle includes an adjusting bracket having magnets mounted on its inner surface and spaced from a flywheel, an adjustment shaft having a threaded rod rotatably disposed through a tubular sleeve disposed on a frame and above the adjustment bracket, a threaded member mounted on the adjustment bracket and connected the threaded rod, and a linking assembly mounting the adjustment bracket to the frame, and including a first member, a first linking member, a first sensor, and a second sensor. The first sensor is disposed on the first member adjacent to the first end of the first linking member, a second sensor is disposed on the first linking member adjacent to the first sensor. A relative position of the first sensor and the second sensor is changed with respect to the corresponding movements of the adjusting bracket.

A wearable device assembly has a housing supporting a controller, display and indicator system thereon. The controller has at least one sensor wherein activity of a user wearing the device is detected. The controller selectively illuminates the indicator system to indicate a level of activity of the user.
