Some embodiments provide an abdominal training machine that uses an adapted reverse crunching motion to minimize stress to the knees, back, shoulders, and neck when training the abdominal muscles. The machine combines weight resistance training with a replicated natural motion of each leg to produce the adapted reverse crunching motion. The adapted reverse crunching motion is performed using a section of the lower part of the body closest to the abdominal muscles while the upper body or torso remains stationary. In some embodiments, the abdominal training machine includes a frame, a body support member, and two individually rotating resistance members. Each resistance member includes a weight assembly for providing a user adjustable amount of resistance.

An exercise apparatus is disclosed. The exercise apparatus may include a frame and a rail suspended from the frame. The rail may have a length extending horizontally. The exercise apparatus may further include two carriages, each configured to roll along the rail independent of one another. A handle may be connected to each carriage. A user may grasp the handles, one with each hand, and execute an exercise such as a chin-up, pull-up, bicep curl, lat pulldown, or the like.

A calf exercise machine has a floor engaging main frame, a user support pivot, a user support assembly pivotally mounted on the main frame via the user support pivot, and a pivotally mounted user engagement device. A user engaging foot plate assembly is pivotally mounted to track movement of the user's feet during a calf exercise, and may comprise either the user support in a standing calf machine or the user engagement device in a seated calf machine. A connecting link translates movement of the user engagement device to movement of the user support so that pivotal movement in the user engagement device results in a self-aligning, pivoting movement of the user support.

A pike pole exercise apparatus is provided for firemen to train and condition themselves for using a pike pole hook. A base has an elongated post attached thereto which extends generally vertically therefrom. An elongated hollow slide member is slidably mounted on the elongated post for sliding thereon and has a weight attached thereto so that a fireman can grip the slide member and slide it up and down on the elongated pole to exercise and train for using a pike pole hook.

The subject matter discloses an exercising device enabled to switch between elliptical course and circular course of footrests used by a user, comprising two main wheels, each connected to a different footrest; two connecting rods, the distal end of each connecting rod is connected to each main wheel and the proximal end of each connecting rod is connected to the body of the exercising device, said connecting rods are enabled to move the two main wheels on a horizontal axis. The subject matter also discloses A mechanism within an exercising device enabling both elliptical and circular movement of a footrest in the exercising device, the mechanism comprising: a main wheel connected to the footrest and rotated upon movement of the footrest; a connecting rod connected on its proximal end to the body of the exercising device and on its distal end to the main wheel; wherein the course of the footrest's movement is elliptical when the distal end is connected to a non-centric position on the main wheel and circular when the connecting rod is connected to a centric position on the main wheel or when the connecting rod is not connected to both the main wheel and the body of the exercising device. The footrests and handlebars of the exercising device fit the new motions enabled by the device. A stepper can also be embedded within the exercising device of the disclosed subject matter.

A handheld exercise device in the form a single nonresilient ball, or a pair of balls, which have a copper surface and have internal permanent magnets embedded within the balls which generate magnetic fields around the outer surface of the ball. The balls may be grasped in the palm of a hand and manipulated so as to combine the therapeutic effects of exercise, copper absorption into the skin, and magnetic field therapy.

An oxygen trainer assembly for use in athletic activities to increase inspiratory muscular endurance, the assembly comprising: a mouthpiece having a mouthpiece opening; a circulation chamber housing having a circulation chamber in fluid communication with the mouthpiece opening; a first endcap having a first endcap aperture and a second endcap having a second endcap opening in fluid communication with the circulation chamber housing; a first endcap insert disposable in the first endcap operative to control the level of air resistance in the assembly during inhalation and exhalation; a one-way valve disposable in the second endcap sized and configured to allow the flow of air away from the circulation chamber during exhalation.

An improved rehabilitation and exercise machine is provided which allows a person with physical limitations, disabilities or chronic conditions to use the machine in order to rehabilitate their muscles, improve joint flexibility, and enhance cardiovascular fitness.
