Abstract: The exercise assembly for squats includes a support frame, a foot plate, a seat member, a wall frame, an upright beam, and a trolley member. The support frame includes a base member, a base post, and a support arm. The seat member is placed relative to the support frame by the foot plate. The seat member is adjustable. The wall frame includes curved knee frame, a knee wall, and a horizontal support beam. The upright beam extends upward from the base member at an angle toward the seat member.

The trolley member slides along the upright beam so that the complete squatting movement tracks along the angle of the upright beam.

Abstract: An exercise arrangement includes a movable support that is movable in a fore-aft direction and simultaneously movable laterally, e.g. about a tilt axis. The support may be a platform movably mounted to a base. A roller and track arrangement may be provided between the platform and the base, to provide movement of the platform in the axial direction relative to the base as well as an axially neutral position of the platform relative to the base. The roller and track arrangement may be in the form of one or more curved roller and track engagement surfaces that extend in the axial direction and that provide a gravity bias of the platform toward the neutral position. The roller and track arrangement may provide tilting movement of the movable platform about the tilt axis. A tilt biasing arrangement biases the platform toward a neutral tilt position relative to the base.

Abstract: The present invention relates to a machine providing a compound leg exercise known as a squat. The purpose of the invention is to provide rotational resistance to the muscles and joints in a compound exercise. The apparatus uses a cable connecting weights to a cam; the cam converts linear resistance to rotational resistance transferred to a driven gear, and then to a second axis and reversed by use of a drive gear meshed to the driven gear. Both gears are aligned to the joints involved in the exercise. Connected to the drive gear is a lever and footplate the user pushes against. The resulting resistance is perpendicular to the direction of force applied by the muscles and joints, while the feet move in a straight line. The present invention can be applied to compound exercises for the upper or lower body in a variety of different embodiments.
