An exerciser includes a supporting member rotatably supported on a base with a pivot axle and having an end portion rotatable relative to the base about the pivot axle. A post is coupled between the end portion of the supporting member and the base, a lever is pivotally secured to the supporting member, and a link is coupled between the lever and the post. The feet of the users may engage with the lever to move the post relative to the supporting member or relative to the base, for elevating the supporting member and exercising the lower muscle groups of the users.
