An exercise device includes a main pulley configured to rotate about a hub and having a first surface, a second surface opposite to the first surface, and a peripheral surface. The exercise device also includes a lower pulley coupled to a resistance drum and a belt wrapped partially around the peripheral surface of the main pulley coupling the main pulley to the lower pulley. Brake lining is positioned inside the resistance drum and are configured to be adjusted inwardly and outwardly along interior sidewalls of the resistance drum. In addition, a cable is coupled to the brake lining to control an amount of resistance to a rotation of the resistance drum, and a crank shaft is coupled to a hub of the main pulley and configured to be operated by feet of an individual for rotating the main pulley about the hub against the resistance to exercise the individual.

An exercise apparatus includes a pair of apparatuses wearable on feet of a user. Each apparatus is configurable between expanded configurations and compressed configurations to simulate a selected motion when the user wearing the pair of apparatuses travels by foot. One of the apparatuses can move towards an expanded configuration while the other apparatus moves towards a compressed configuration.

A portable apparatus is disclosed for generating electrical power comprising a stator comprising a plurality of coils, coil units or coil segments for independently generating electrical power, wherein the stator comprises a printed coil laminate comprising a sheet of insulator material and a printed conductor comprising conductive ink printed upon the sheet of insulator material arranged to form the plurality of coils, coil units or coil segments and a reciprocator comprising a magnet, the reciprocator being responsive to vibrations and/or shocks and moves in that regard within the environs of the stator so as to generate electrical power. The apparatus is connectable to a portable electronic device so as to power that device and/or to a storage device for storing the generated electrical power.

Embodiments of a strength training apparatus and related methods are provided. In one embodiment, a strength training apparatus may include a tower, a first arm and a second arm each pivotally coupled with the tower and each being configured to be selectively positionable independent of each other at multiple angles relative to each other, a first pulley coupled to an end of the first arm, a first cable extending through the first arm and the first pulley, a second pulley coupled to an end of the second arm, a second cable extending through the second arm and the second pulley, a magnetic mechanism coupled to the first cable and the second cable and configured to provide multiple levels of resistance to a user pulling on the first cable and/or the second cable, and a control panel located on the tower.

A weight training sled 100 characterized by one or more of (A) rotatable wheels 130 in contact with ground, (B) curvilinear push handles 140 with comfortably spaced, and inwardly and/or downwardly angled hand grips 143, and (C) an elevated tow hook 160.

A resistance regulating device for a wheel of a training device is disclosed. The resistance regulating device comprises a rotary mechanism pivotally connected with a stationary mechanism and a motor with other components to rotate the rotary mechanism and hence a distance between magnets of the rotary mechanism and the wheel is changed. In addition, an optical detection device may be used to detect and define a minimum resistance and a maximum resistance and hence to adjust a resistance in a stepless manner An emergency brake mechanism may be further employed.

An exercise bicycle comprising a frame including a first portion and a second portion, the first and second portions being pivotably coupled to each other and being adjustable in a plurality of positions, and a support rod including a first end and second end, the first end pivotally coupled to the first portion of the frame and the second end pivotally coupled to the second portion of the frame, the support rod configured to adjustably lock the first and second portions in each of the plurality of positions.

Among other things, a rowing exercise machine includes a movable inertial element, an eddy current brake coupled to the movable inertial element, a rowing grip coupled to the movable inertial element, and control circuitry coupled to the eddy current brake to cause a resistance to motion of the rowing grip during part of a rowing stroke. The resistance to motion of the rowing grip during the drive phase of the rowing stroke conforms to a target feel for a rower. The target feel corresponds to a feel for a rower of a target other rowing exercise machine or other target feel of interest.

The present invention concerns an improved rowing machine, for the execution of gymnastic exercises similar to strokes and the like, comprising actuating means movable between a rest position and a working position, and a first braking device, operatively connected to said actuating means configured to brake the motion of said actuating means during the passage from said rest position to said working position, characterized in that said rowing machine comprises a second braking device operatively connected to said actuating means, said second braking device being configured to brake the motion of said actuating means during the passage from said rest position to said working position.
