A weightlifting machine that includes a pulley system and a cable system that attaches to a weight rack frame to allow a user to perform a weightlifting exercise. The pulley system may include a first pulley and a second pulley where the cable system engages each pulley. The cable system may have a first end connected to a grip attachment and a second end attached to a resistance element. The resistance element may include a resistance band, a weight support that holds a weight plate, a set of weight plates, or other type of resistance element. The cable system may extend from the pulley through an opening located one of the frame members that form the frame.

A fold-up trampoline, having at least three posts arranged in parallel to one another and to a vertical direction (V), wherein a jumping bed is tensioned between the at least three posts, at least three bracing struts which connect a respective other pair of posts arranged next to one another in a peripheral direction (U) of the trampoline and stabilize these posts in a horizontal direction (H), wherein each bracing strut is foldably mounted on both posts arranged next to one another in the peripheral direction (U) and has at least one central joint, which is provided in a central region (B1) of the bracing strut, wherein all the posts arranged next to one another in the peripheral direction (U) can be moved towards one another in order to fold up the trampoline.

An exercising assembly for fitness training and rehabilitation includes a first base, which is positionable on a substantially horizontal surface. An engagement module is selectively engageable to the first base so that the engagement module is positioned proximate to a first end of the first base. A plurality of attachment elements is engaged to the first base, the engagement module, and to a plurality of tensioners. The attachment elements are selectively mutually couplable. A plurality of first interface elements is selectively engageable to the engagement module. Respective attachment elements of the plurality of attachment elements are engaged to each of the first interface elements. Respective tensioners thus are extendable between a respective first interface element and one or more of the first base and the engagement module. The respective tensioners provide resistance to the user moving the first interface elements.

An exercise apparatus comprising a seat and a foot support secured on a longitudinal support frame, the seat and foot support being configured to support the torso and feet of a user so that the hips of the user are positioned in an exercise area defined between the seat and foot support, wherein the apparatus further includes an arm having a first end and second end, the first end being mounted to the support frame and the second end including a deformable material, wherein the first end is mounted for pivotal motion of the arm within a limited range, the arm including a support bar restricting pivotal motion within the exercise area whereby the second end is suspended within the exercise area and enabled for pivotal motion in a transverse direction relative to the support frame, the arm further being operatively associated with a source of resistance to the pivotal motion of the arm in the transverse direction relative to the support frame.

An exercise device (10) for swallowing rehabilitation with a variable resistance, the exercise device (10) comprising an exerciser body (20) forming a support, chin receiving means (30) movably connected to the exerciser body (20), exercising means (50) for creating resistance when the chin receiving means (30) is moved towards the exerciser body (20), and a lever arm (32, 70) connected to the exerciser body (20) via a fulcrum (45, 75) and configured to interact with the exercising means (50), wherein the exercising means (50) or the fulcrum (75) is displaceable to provide a variable resistance against movement of the chin receiving means (30) towards the exerciser body (20).

Exemplary arrangements provide leg training devices suitable for high intensity training of hip flexors while simultaneously training the extensors of hip and knee joints. The exemplary leg training devices include foot fixings which are permanent vertically movable components of the device, each of which are configured to releasably engage a foot of a user in operative engagement therewith while limiting the movement of the foot relative to the foot fixings. Each of the foot fixings is operatively connected to a suitable mechanism that provides a resistance force to vertical movement of the foot fixing by the user's leg. In exemplary arrangements the resistance force may be selectively variable with regard to the magnitude and/or point of application so as to provide the desired training regimen.

A leg muscle, abdominal muscle, and spinal exercise device adapted for imparting curvature to a lumbar or sacral spine of a user and for manipulating the spine and intervertebral discs with decompression force includes a frame for placement on a floor. The frame has a top surface and a bottom surface, wherein the top surface and bottom surface are in a spaced apart relationship forming a hollow portion there between. At least one inflatable bladder is carried by the top surface of the frame. A body strap attachment passes through the frame in non-fixed relationship and is partially disposed within the hollow portion for encompassing the user's thoracic-sacral spinal region and securing said frame. An elongate stirrup strap member is attachable to the body strap attachment thereby connecting to the user's spinal region. A stirrup is attachable to the stirrup strap member distal end.

A system and method for networking fitness machines for allowing an instructor to control various settings for a plurality of exercise machines simultaneously, and for allowing an individual user and/or trainer to modify the settings of an individual exercise machine. The system and method for networking fitness machines generally includes a trainer remote control device, one or more machine-mounted onboard trainer controllers, and a machine-mounted onboard user controller. The trainer remote control device may be securely mounted to the arm of a trainer so that the trainer's hands remain free to instruct exercisers. The trainer remote control device includes a touch screen that displays selections corresponding to various settings on the exercise machines. The trainer remote control communicates with the plurality of exercise machines via a wireless network or Bluetooth connection allowing the trainer to change the settings of a plurality of exercise machines in a class mode simultaneously.
