A method of varying a dynamic resistive force during a strength training exercise includes receiving a selection of the strength training exercise from a set of available strength training exercises and obtaining exercise logic for the strength training exercise from computer memory. The exercise logic provides instructions for generating a vector that defines the dynamic resistive force provided at an end effector of a strength training apparatus during the strength training exercise. The method includes determining a real-time geometric arrangement of a plurality of cables coupled to the end effector, generating, based on the real-time geometric arrangement of the plurality of cables and the exercise logic, time-varying operating setpoints for a plurality of actuator assemblies coupled to the plurality of cables, and exerting the dynamic resistive force at the end effector by controlling the plurality of actuator assemblies in accordance with the time-varying operating setpoints.

An isometric force resistant exercise tool has a left handle form interfaced to a right handle form over an axle shaft locked to the right handle form, the axle shaft supporting a pressure plate, a compress able spring or set of springs, and a compression adjustment handle threaded onto the axle shaft and abutting the compress able spring or spring set, the pressure plate adjacent in assembly to a friction-resistive material fixed on the left handle form, the left handle form including a piston form interfacing with a ring housing on the right handle form, the piston form adjacent in assembly to a friction-resistive material fixed on the right handle form. Gripping the handle forms and rotating the against force resistance exercises one or more muscle groups.

A tensile strength training device having a handheld housing with a curved electronic display panel defining a housing channel and with a left side panel and a right side panel each flanking and coupled to the curved electronic display panel, each with a sidewall defining a concave cavity, two opposing handle apertures, and two opposing bracket apertures. Left and right U-shaped handle brackets are disposed within the respective wo opposing bracket apertures and coupled to a handle member disposed within the concave cavity thereon for grasping by a user and disposed within the two opposing handle apertures. The device includes a printed circuit board electrically coupled to a power source, a force sensor operably coupled to the left and right U-shaped handle brackets, and operably configured to measure a tensile force applied thereto that is able to be displayed around at least 180° of the curved electronic display panel.

The present invention may be embodied as a system or method for dynamically exercising a user's neck muscles. The system includes a headset, an arm attached thereto, a weight, and at least one motor to move the weight, for example, about the arm. The weight may be mounted eccentrically on a radial track that is rotatable by one motor and moved linearly by another motor. The direction of the arm, the distance between an apex of the headset and the weight, the eccentricity of the weight on the axis, and the speed of rotation of the motor are all parameters that can be adjusted by the caregiver or user, either manually or via controlling software.

An isometric exercise system comprised of a network-enabled isometric exercise apparatus, force correction equations, and an isometric exercise companion software application. The isometric exercise apparatus can include force-receiving components, a measurement component, a pivot assembly, and a structural assembly. The measurement component can measure the amount of applied force. The pivot assembly can rotationally transfer the applied force to the measurement component. Force analysis of exercises can indicate that only a tangential component of the applied force is mechanically transferred to the measurement component via the pivot assembly. The force correction equations can translate the measured force into the tangential force transferred by the pivot assembly. The isometric exercise companion software application can present the amount of weight manipulated by the user to perform the exercise calculated using the force correction equation and the measured force. This calculation can have greater accuracy and consistency than utilizing the measured force.

An exercise prop for use in the performance of floor-based exercises such as Pilates and isometric exercises is provided. The exercise prop includes a braided body having a looped handgrip at each end. A method for fabricating an exercise prop is also provided.
