Fitness apparatus

An arrangement comprising two fitness apparatuses, wherein each fitness apparatus of the two fitness apparatuses include:

• a housing, the housing including a first supporting element which is configured as a platform for supporting a foot or a part of an arm, and a second supporting element arranged thereon, the first supporting element and the second supporting element being each movable linearly in a first spatial dimension and in a second spatial dimension, the first spatial dimension and the second spatial dimension being located at right angles to one another, wherein the housing has at least one spring, by which a movement of the first supporting element or the second supporting element out of a respective starting position is counteracted by a force,
• wherein the housing further comprises:
• a) a first coupling element, which couples the linear movement of the first supporting element in a first direction of a first of the two spatial dimensions to a linear movement of the second supporting element in a second direction, which opposes the first direction in the first of the two spatial dimensions, the first coupling element comprising:
• i) a first gearwheel, which is arranged centrally on a surface area of the housing, and which has an axis of rotation which is at right angles to the first spatial dimension and to the second spatial dimension;
• ii) a first rack fastened to the first supporting element and extending in the direction of the first spatial dimension;
• iii) a second rack fastened to the second supporting element and extending in the direction of the first spatial dimension;
• b) wherein the first rack and the second rack engage with the first gearwheel on opposite sides of the first gearwheel;
• c) a second coupling element, the second coupling element comprising:
• i) a second gearwheel, which is arranged centrally on the surface area of the housing and which has an axis of rotation which is at right angles to the first spatial dimension and to the second spatial dimension, the second gearwheel being arranged above or beneath the first gearwheel;
• ii) a third rack fastened to the first supporting element and extending in the direction of the second spatial dimension;
• iii) a fourth rack fastened to the second supporting element and extending in the direction of the second spatial dimension;
• d) wherein the third rack and the fourth rack engage with the second gearwheel on opposite sides of the second gearwheel;
• wherein the housing of a first of the two fitness apparatuses is configured for placing on a floor and the first supporting element and the second supporting element of the housing of the first of the two fitness apparatuses are suitable for having feet placed in position on them, wherein the first spatial dimension and also the second spatial dimension are oriented essentially parallel to the floor, and wherein a second of the two fitness apparatuses is connected in a releasable manner to the first of the two fitness apparatuses, and is spaced apart therefrom by a first distance, via an upright, which extends essentially in a third spatial dimension, which is located at right angles to the first spatial dimension and to the second spatial dimension.
