A resistance-generating device includes a resilient body extending between opposed ends. The resilient body has a first portion extending between first and second mounting members of the device, and a second portion extending between the first and second mounting members. The first portion is spaced apart from the second portion, and the first and second mounting members are made of an inelastic material. At least one of the first and second mounting members is removably mountable to a corresponding one of the first and second mounting members of another resistance-generating device. The resilient body generates resistance upon the first and second portions being elastically deformed by displacement of the second mounting member mounted to a second structure relative to the first mounting member mounted to a first structure.

A pedal assembly for electromechanical exercise or rehabilitation of a user is disclosed and can include pedals to engage appendages of a user. A spindle supports each pedal and has a spindle axis. A pedal arm assembly is located between the spindle and a rotational axle of the equipment. The pedal arm assembly is radially offset from the spindle axis to define a range of radial adjustability for the pedal relative to the rotational axle. The pedal arm assembly can include an electrically-actuated coupling assembly to adjust the radial position of the pedal in response to a control signal, and regulate motion of the user engaged with the pedals.

An exercise apparatus for attachment to an exercise rack including an arm, including: at least one mounting prong connected to the arm; and, a stand including a pivot point, wherein the pivot point defines a pivot axis substantially transverse to a longitudinal axis of the arm, and wherein the stand is configured in a first, vertical configuration when the apparatus is at rest and a second, largely horizontal configuration when the apparatus is in motion, and wherein the stand is rotatable with respect to the arm about the pivot axis to transition the stand from the first configuration to the second configuration.

A direct drive resistance system for exercise machines having a weighted moment arm that is lifted and lowered by a lifting moment arm and lifting component, which is moved by a force transfer assembly, which is operatively connected to a rotary component of an exercise machine, such that when the exercise machine is activated the force transfer assembly, the lifting moment arm, the lifting component and the weighted moment arm move concurrently to create a resistance force to the motion of the exercise machine.

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.

The present invention relates to an exercising device (1) comprising a lever or power arm (10) which is able to be arranged by a first end (12) on a retaining element (16) at a first articulated joint (13) in a way pivotable about a pivot axis or pin (14), whereby a resistance element (18) is able to be coupled by a first end region (20) at a first coupling point (22) on the power arm (10), and by a second end region (24) at a second coupling point (26) at a second articulated joint (25) on the retaining element (16). The exercising device (1) is able to be detachably arranged on a structure (40) by means of an engaging connection, which is formed by a hook-shaped recess (50) and a rod-shaped element (46) and whereby the exercising device (1) is lockable in an engaged position by means of a fixation.

A universal gym exhibits improved versatility employing a frame supporting a weight stack connected via cable to an exercise attachment point, which further engages a floating pulley with an extension cable. Accessory receiving ports throughout the frame allow placement of the floating pulley virtually anywhere the athlete desires, affording a vast array of exercises employing the weight stack. Free weights, elastic bands, and the weight stack, alone or in combination, can provide a diverse resistance. Decorative panels, optionally mounted with hollow-headed bolts each having an axial recess for receiving and retaining a panel-mounting rivet, can disguise the universal gym when not in use.

Provided are apparatuses for augmenting human speed, human-driven compliant mechanisms, artificial limbs to augment human movement, and the like. The apparatuses can include variable stiffness mechanisms including springs that can be configured to selectively store and subsequently release energy generated by human movement. The apparatuses can selectively release the captured energy supplied by the human to provide force and power output beyond the physical capability of the human.

The invention is embodied in an exercise system that can allow its user to counterbalance the effects associated with a predominantly sedentary lifestyle though a fitness device that comprises a combination of (a) supporting the lower body in a manner that permits a user's upper body to act as a third class lever with the user's hips operating as fulcrum and (b) engaging in resistance exercises with the upper body in a horizontal position, unsupported above the greater trochanter.

An exercise attachment apparatus for attachment to a lever arm pivotably connected to an exercise rack, including at least one mounting prong connected to the lever arm; and, a stand including a pivot point, wherein the pivot point defines a pivot axis substantially transverse to a longitudinal axis of the lever arm, and wherein the stand is rotatable with respect to the lever arm about the pivot axis.
