When pivoting either pedal, the hydraulic liquid is forced to flow to another space and generates resistance. When the pedal is released, the hydraulic liquid flows back to the main space to allow the pedal to be pivoted upward. Similarly, if the buffering unit uses a pneumatic cylinder, when the pedal is pivoted downward, the air is compressed to generate resistance, and when the pedal is released, the pedal is pivoted upward by the force from the expanded air. Besides, an adjustable damping device may be used to be cooperated with the hydraulic unit or a pneumatic unit, however, the adjustable damping device is complicated and expensive. In addition, the conventional stepper exerciser is bulky and heavy.

Each of the tworesilient boards 31 has afirst end 311 and asecond end 310 which is a free end. Aneck 34 extends from themount 32. The two respectivefirst ends 311 of the tworesilient boards 31 are merged together to form a V-shaped portion and the V-shaped portion is connected to theneck 34 extending from themount 32. The two respectivesecond ends 310 of the tworesilient boards 31 extend upward in a curved form or a straight form. The two respectivesecond ends 310 of the tworesilient boards 31 are respectively supported at the middle portion of the underside of the two pedal supports 20. Arounded angle 33 is defined at the V-shaped portion and between the twofirst ends 311 of the tworesilient boards 31. - The two
resilient boards 31 are located symmetrically to thebase 10, and the twopedal supports 20 are located symmetrically to thebase 10. Theresilient boards 31 both are elongate and resilient boards which are made by metal. - The
neck 34 is connected to the two respectivefirst ends 311 of the tworesilient boards 31, and theneck 34 swings relative to themount 32.
