Exercise device and exercise system having the same

An exercise device, comprising:

• a frame assembly including a base frame;
• a running deck;
• a running belt surrounding the running deck;
• a cushioning means arranged between the running deck and the base frame to attenuate the impact force exerted by the user through the running belt and the running deck, wherein the cushioning means is arranged along lateral edge regions of the running deck, while a central region of the running deck does not come into contact with the cushioning means;
• and
• a limiting installation structure comprising upright members extending upward from the base frame and limiting members fixed to the upright members, wherein each of the limiting members are used to restrict the movements of the running deck along a length direction corresponding to the direction of travel of the running belt and a width direction perpendicular to the direction of travel of the running belt, and wherein the limiting members that are adjacent along the length direction are spaced apart by a distance in the range of 50% to 90% of the length of the running deck;
• wherein the running deck is fixed to the base frame only at its first and second ends of the running deck via fixing devices, such that a central region and lateral edge regions of the running deck are not in direct contact with the base frame, wherein the lateral edge regions accommodate the cushioning means and the central region remains suspended to enhance cushioning effect and stability under cooperation with the limiting installation structure.
