Abstract
A method and apparatus for exercising internal and external oblique muscles utilizes lateral forces generated by the feet and maintain the upper body in a fixed position to facilitate exercise of the oblique muscles. The apparatus and method vary the inertial forces applied outside the feet to affect the degree of difficulty of the exercise.
Claims19
A mechanical system for exercising target oblique muscles of a body, comprising:
- a base;
- a stationary neck rigidly coupled to the base to prevent rotation of the stationary neck with respect to the base;
- a handle coupled to a distal end of the stationary neck;
- a platform in rotational contact with the base, the platform having a centerline substantially aligned with the stationary neck;
- and
- a divider aligned along the centerline and rigidly coupled to the platform, the divider having first and second opposing vertical faces of fixed height extending upwardly from the platform, wherein a user maintains upper body substantially stationary by holding the handle and applies forces through an inside portion of both feet normal to the first and second opposing vertical faces of the divider, respectively, to cause rotation of the platform with respect to the base and exercise the target oblique muscles.

An exercise machine, comprising:
- a base;
- a stationary shaft rigidly coupled to the base to prevent rotation of the stationary shaft with respect to the base;
- a handle coupled to the stationary shaft;
- a platform in rotational contact with the base, the platform having a centerline substantially aligned with the stationary shaft;
- and
- a divider aligned along the centerline and rigidly coupled to the platform, the divider having first and second opposing vertical faces of fixed height which provides a rotating leverage point of the rotatable platform when forces are applied normal to the first and second opposing vertical faces of the divider.
3 more elements
An exercise apparatus to activate the oblique muscles of a body, comprising:
- a base having a fixed portion;
- an extendible shaft rigidly coupled to the fixed portion of the base to prevent rotation of the shaft;
- a handle coupled to the extendible shaft to allow for an upper portion of the body to be held in a stationary position;
- a foot plate in rotational contact with a second portion of the base, the foot plate having a centerline substantially aligned with the extendible shaft, wherein the foot plate allows for a lower portion of the body to turn;
- and
- a divider aligned along the centerline and rigidly coupled to the foot plate, wherein forces applied normal to first and second opposing vertical faces of the divider causes the foot plate to rotate.
3 more elements
A method of manufacturing an exercise machine, comprising:
- providing a base;
- connecting a shaft rigidly to the base to prevent rotation of the shaft with respect to the base;
- connecting a handle to the shaft;
- placing a platform in rotational contact with the base, the platform having a centerline substantially aligned with the shaft;
- and
- affixing a divider aligned along the centerline and rigidly coupled to the platform which provides a rotating leverage point of the platform when forces are applied normal to first and second opposing vertical faces of the divider.
