    • An adjustable inertial exercise device has an elongate member with first and second threaded portions with opposite-handed threads. First and second nuts, each having at least one radial flange, are respectively rotatably engaged with the first and second threaded portions of the elongate member. A sleeve is slidably mounted over the first and second nuts. The sleeve has an internal bore with first and second bearings and at least one longitudinal groove slidably engaged with the radial flanges of the first and second nuts. Elastic resistance elements interface between the first and second nuts and the first and second bearings. Rotation of the elongate member relative to the sleeve one direction causes the nuts to move apart from one another compress the resistance elements. Rotation of the elongate member relative to the sleeve in the opposite direction causes the nuts to move toward one another and expand the resistance elements.
    • 可调惯性锻炼装置具有细长构件,其具有带有相反螺纹的第一和第二螺纹部分。 每个具有至少一个径向凸缘的第一和第二螺母分别与细长构件的第一和第二螺纹部分可旋转地接合。 套筒可滑动地安装在第一和第二螺母上。 套管具有内孔,其具有第一和第二轴承以及与第一和第二螺母的径向凸缘可滑动地接合的至少一个纵向凹槽。 弹性阻力元件在第一和第二螺母与第一和第二轴承之间接合。 细长构件相对于套筒一个方向的旋转使得螺母彼此分开地压缩电阻元件。 细长构件相对于套筒沿相反方向的旋转导致螺母朝向彼此移动并且使电阻元件膨胀。
