Another example is shown in FIG. 14, in which a pair of foot paddles S is alternately trodden to simulate a stair climbing exercise. Another example is shown in FIG. 15, in which a pair of foot paddles S is swingably suspended with a pair of parallel links T to be alternately moved back and forth to simulate a cross country skiing exercise. In a combined fitness machine shown in FIG. 16A, the pair of foot paddles S is provided on the endless belt B and is alternately trodden to simulate a stair climbing exercise. The device is also available to simulate a walking exercise as shown in FIG. 16B, in which the aforementioned foot paddles S are individually folded upwardly to be retracted.
- Many of the fitness machines of the aforementioned types are used indoors at home, thus being required to provide a sufficient performance of these types of bodily exertion and to be compact in size. However, many of the aforementioned conventional fitness machines are provided with a single function and thus a single device cannot provide the performance of different types of bodily exertion. Therefore, a user who would wish to simulate other exercises would have to purchase discrete dedicated fitness machines one after another which were provided with the functions for simulating the exercises the user desired. Consequently, this would lead to not only additional expenditures but also to storage problems in a household environment. In addition, the combined fitness machine of the aforementioned conventional type was too heavy to be readily moved or stored.
