A system and method of using an exercise system having a resistance structure of handles connected to cables, which cables are connected to at least one pneumatic cylinder that creates resistance, wherein the resistance is adjusted by the user via actuators in the handles, so that the user does not need to release the handles to adjust the resistance. The system is typically supported by a frame to surround the user, and the pneumatic cylinder may be connected to an equalizing tank that may be housed within or integrated into the frame. The system may include a monitor to visually display system parameters and other information to the user. The system may calculate resistance and work done by the user by measuring piston displacement and speed, as well as using accelerometers or other devices integrated into the handles.

The present invention involves a connecting device of elastic exercise cord with straps, which comprises a hollow body (12) provided by a through-made channel (13) with an upper opening (14) and a lower opening (15), wherein into the upper opening (14) arms (7,8) of a strap (3) are introduced first by its upper section (9), these arms (7,8) are passed through the channel (13) and bended over the edge of the lower opening (15) about 180° and the arms (7,8) are arranged along outer surface of the hollow body (12) up to the outer edge of the upper opening (14), wherein above the upper opening (14) the lower sections (10) of the arms (7,8) of the strap (3) are joined with upper section (9) to one joint, wherein the hollow body (12) with above mentioned arrangement of arms (7,8) is arranged in the cavity (16) of the tubing core (2) and this joint of the lower sections (10) of arms (7,8) of the strap (3) with upper sections (9) is together with the tubing core (2) provided by a collet (17) and the outer surface of the hollow body (12) together with portion of the strap (3) is wrapped.

An exercise apparatus comprises a platform having a front roller, a rear roller and an endless belt mounted around the front roller and the rear roller for allowing a user to perform a first exercise type of a relatively lower resistance or a second exercise type of a relatively higher resistance. A front frame is mounted at a front side of the platform and has at least one holding portion adapted to be grasped by the user. One or more control interfaces controls the first exercise type and the second exercise type.

A multi-purpose athletic training platform exercise device is provided. A user may stand atop a platform and exercise while connected to a downward pulling source of resistance. This machine allows the user to walk forwards, backwards and side-to-side freely while still having attachment to the resistance source via a connecting means. This will activated all the muscles in the lower body while tractioning the lower back and helping to reduce pelvic tilt. The resistance maybe varied during the user effort. The user is able to step off the machine to climb up or down a step, or walk up and down a ramp that may be provided.

A lat pulldown fitness device includes a base, a magnetorheological fluid (MRF) resistance provider, a motor, a gear train, pulleys, a cable assembly, a pulldown bar and a controller. The MRF resistance provider and the motor provide a resistance functioning as a load weight of pulling down the pulldown bar. The controller controls a current input to the MRF resistance provider to change the strength of the resistance generated from the MRF resistance provider. During a workout, the resistance provided by the lat pulldown fitness device is changeable precisely, conveniently, and quickly. Unlike its conventional counterparts which require bumper plates for use as weights, the lat pulldown fitness device is not limited to weight adjustment based on unit bumper plate but features plenty choices and controllable resolution in terms of strength of training. The MRF resistance provider is more compact and lightweight than its conventional counterparts.

Apparatus (60) for supporting a subject (2) in an inverted state comprises a ground engaging plinth (8) and a support platform (12) pivotally coupled to the plinth (8) about a first pivot axis (15) so that the support platform (12) is pivotal between a first state with a subject (2) in a supine state on the support platform (12) and a second state with the subject (2) inverted on the support platform (12). The subject is supported in the inverted state on the support platform (12) by shoulder engaging elements (24), and is secured to the support platform (12) by a torso strap (35). A foot engageable element (77) connected to a weight carrying bar (84) through connecting members (79,82) extending through an elongated slot (80) in the support platform (12) allows leg and abdominal muscles to be exercised by urging the foot engageable element (77) in the direction of the arrow A against weights (85) carried on the weight carrying bar (84). A carrier element (81) slideable on a guide bar (83) guides the foot engageable element (77). Handgrips (86) are connected by steel cables (87) around pulleys (88,89,90,91) to the weight carrying bar (84) for facilitating exercising of arm, shoulder, chest and back muscles.

An adjustable training apparatus includes a harness that is worn over an upper torso of a person training, and two tensioning devices that are secured to the harness. Each tensioning device includes a cord that extends from the device, with an outer end of the cord being configured to be secured to a body part of the person training. A method of conducting anaerobic resistance training is further disclosed.

There is accordingly provided a flexible sheet assembly for stretching exercises. The assembly has a longitudinal axis. The assembly includes an elongate flexible sheet having a pair of spaced-apart longitudinally extending sides. The sheet has a pair of spaced-apart ends that extend between the sides. The sheet has a first longitudinal portion extending from a first one of the ends towards a second one of the ends. The sheet has a second longitudinal portion extending from the second one of the ends towards the first one of the ends. At least a first one of the longitudinal portions of the sheet has an aperture extending therethrough. Portions of the first one of the longitudinal portions of the sheet adjacent to the aperture are curved.
