Method of delivering the object related message by using the format of the wide-frequency sound signal is proposed. Due to both the well-known Doppler effect and the well-known phenomena that the intensity is inversely proportional to the distance in the three-dimensional space, the transmitted wide-frequency sound signal itself indicates some properties of the objected attached by the wide-frequency sound signal transmitter, such as the motion and the distance. Besides, the delivered wide-frequency sound signal also carries the contents detected by one or more corresponding detectors. Such method has many possible applications, such as intelligent fitness equipment, health care, indusial application and so on.

Systems and methods for fitness tracking are provided. An exercise apparatus is in networked communication with a fitness tracking computing system. The configuration and location of movable components of the exercise apparatus is determined based on sensors. This information is provided to the fitness tracking computing system via networked communication.

Described herein are systems and methods of guiding a user to achieve musculoskeletal counterpulsation. A method may include receiving a cardiovascular cycle signal from a first sensor; determining a heart rate of the user based on the cardiovascular cycle signal; receiving a rhythmic musculoskeletal activity timing signal from a second sensor; determining an actual musculoskeletal activity cycle (MSKC) to cardiovascular cycle (CC) timing relationship; comparing the actual MSKC to CC timing relationship to a target MSKC to CC timing relationship; providing a recurrent prompt to the user as a timing indication for performance of a rhythmic musculoskeletal activity to guide the user to achieve a musculoskeletal activity cycle rate (MSKR) that approaches the target MSKC to CC timing relationship; and altering a feature of the recurrent prompt based on a determined alignment between the actual MSKC to CC timing relationship and the target MSKC to CC timing relationship.

An electric generator which can be coupled to an exercise machine is described. The electric generator is connected to a power grid. Using the mechanical movements of the exercise machine, the generator can produce and feed electricity into the grid, thereby creating a decentralized grid system which is immune to node failures. The generator can communicate with a smart device of a user. The generator can inform the user of the amount of electricity generated by the user while working out. The generator or an application of the smart device can communicate this data to a service provider. Using this data, the service provider can pay the user for the electricity generated. In particular, the service provider can utilize a cryptocurrency to reward the user for the human generated electricity.

Embodiments disclosed herein relate to a garment system including at least one sensor and at least one actuator that operates responsive to sensing feedback from the at least one sensor to cause a flexible compression garment to selectively constrict or selectively dilate, thereby compressing or relieving compression against at least one body part of a subject. Such selective constriction or dilation can improve muscle functioning or joint functioning during use of motion-conducive equipment, such as an exercise bike or rowing machine.

A method for operating a motivation enhancing exercise system includes an exercise device configured to be driven by an exercising user, a head mounted output device configured to output a visual and/or an audible output for an exercising user, and a processing unit. Movements of a movable part of the exercise device are measured by means of a first sensor unit mounted on the movable part, and movements of a head of the user are measured by means of a second sensor unit comprised in the head mounted output device. The processing unit determines an activity being performed by the exercising user, and generates an output signal for the head mounted output device, in accordance with the determined activity. The head mounted output device provides a visual and/or audible output for the exercising user in accordance with the output signal.

The present invention provides exercise attachments for modifying an inclinable weightlifting system using a user's body weight. A pair of vertical support devices providing rigidity and elevate the weightlifting system off the ground to aid in a user mounting and dismounting the system. A pair of adapter arms enable a user to tailor exercise attachments to target specific muscle groups and specific regions of that muscle group. The pair of vertical support device and pair of adapter arms may be incorporated into an inclinable weightlifting system to enable a user to perform various rowing and bench press exercises.

The present disclosure provides an elliptical crawler. The elliptical crawler includes a front support having an adjustable height and an assembly of elliptical rowing body having two extendible arm supports and two foot supports. Methods of making and using the elliptical crawler are also disclosed.

Exercise device, having at least one elongate track onto which a seat and a footrest are slidingly movably arranged, such that the seat and the footrest are mutually independently movable along the at least one track, a resistance element connected to a handle via a drive cord through which the resistance element can be driven upon pulling the handle towards the seat, and a cord guiding member arranged between the handle and the resistance element over which the drive cord passes, wherein the cord guiding member is arranged stationary with respect to the footrest, and wherein the resistance element is arranged stationary with respect to the at least one track.

A digitally enhanced exercise system includes a proximal section comprising a first structural member and a platform; a distal section comprising a second structural member and an interface, wherein the interface is attached to the second structural member by a mount; a spine that is spans between the first structural member and the second structural member; a carriage configured to move in a single axis along the spine; a tension system, wherein the tension system is capable of resisting the carriage from moving; a sensor array arranged so as to detect changes in weight on the carriage; and a processor. Other aspects are also described and claimed.
