Abstract: A hip loading board for exercise includes linear-motion elements. The linear-motion elements include linear-motion bearing motion elements (e.g. a linear slide). One or more linear-motion elements of the hip loading board can be designed to provide free motion in one direction. Example linear slides (compound slides, dovetail slides, rack slides, ball bearing-based slides, magnetic slides, etc.) can be non-motorized dovetail slides, ball bearing slides, roller slides, etc. that provide a low-friction linear movement. The hip loading board can include one or more interchangeable resistance elements that provide a force to return a moving plate to a start position. The interchangeable resistance elements may also provide a linear resistance (e.g. any material which creates a constant resistance or tension, variable resistance or tension, etc.).
