An elliptical trainer includes a main frame having two opposite sides each having a linking device, a stepping device and an interlocking device mounted thereon wherein the interlocking device is provided to connect the linking device and the stepping device. A damping device is mounted on the main frame and operated with the two interlocking devices for promoting the exercise effect of the elliptical trainer. A long axis of the elliptical foot motion of the two stepping device is adjusted due to the step force from the operator for changing the working stroke.

An exercise guidance system and method display either a workout option or different exercise options based on a person's exercise objectives. In one embodiment, the displayed option or options is additionally based at least partially upon a metabolic equivalent. In another embodiment, the displayed option or options is additionally based at least partially upon the time current available time for the workout.

An exercise apparatus (1), comprising: a box-shaped element (2) configured to be transported on lorries and provided with a lower wall (3), an upper wall (4) and a lateral wall (5) which together form an inner space (6), with said lateral wall (5) having a plurality of faces (F1, F2, F3, F4) and comprising, on at least one of the faces (F1, F2, F3, F4), at least one portion (7) which is movable between a closed position (C), in which it forms a configuration (B) which minimises the dimensions of the box-shaped element (2), and an open position (A), in which the movable portion (7) projects towards the outside (8) of the box-shaped element (2) and forms an opening (9) in the lateral wall (5) designed to put the inner space (6) in communication with an outside environment (8); at least one exercise machine (10) to allow a user (35) to exercise, said exercise machine (10) being designed to occupy the inner space (6) of the box-shaped element (2) at least while in the configuration (B) of minimum dimensions; means (11) for generating electrical power which can be used for supplying electrical loads of said box-shaped element (2).

Combination of electro heat (exposure of the athlete to infrared light) with simultaneous exercise in machines such as treadmill, bicycle, elliptic machines and generally any machine for muscle exercise with the aim of increasing muscular strength, losing weight, cures from muscular diseases, steatolysis.

Luminous ultraviolet radiance is produced by filamentous tungsten lamps which are in α metal reflex. In any conventional aerobics machine there are filamentous tungsten lamps which are in metal reflector in proper arrangement and on stable metal bases, on the right, on the left and behind the athlete, which produce great temperature, transmitting ultraviolet radiance which has nothing to do with ultraviolet or any other kind of radioactive radiance. As the athlete is performing the exercise, simultaneously surface heating is obtained by the infrared light of lamps with the increase of the number of white blood corpsules, faster metabolism and better circulation. The result of it is the faster and more effective burning of body fat, providing the ability to exclude (remove) big amounts of unwanted toxins from the human body.
