Abstract
A weight-balanced apparatus, comprising: a main body shaped substantially like a hollow sphere with spherical caps removed in a same central axis of the body to create two opposing openings sized to account for the natural motion of a user's arm during exercise and where the main body is balanced in each of at least three dimensions from a center point of the sphere, wherein each of the two opposing openings have a continuous, rotationally symmetric beveled edge around the opening; and, a hand hold traversing centrally through the hollow of the spherical main body through the center point and transverse to the central axis.

A weight-balanced apparatus, comprising:
- a main body shaped substantially like a hollow sphere with spherical caps removed in a same central axis of the body to create two opposing openings sized to account for a natural motion of a user's arm during exercise and where the main body is balanced in each of at least three dimensions from a center point of the sphere,
- wherein each of the two opposing openings have a continuous, rotationally symmetric, beveled, upper edge around the opening;
- and
- a hand hold traversing centrally through the hollow of the spherical main body through the center point and transverse to the central axis
- wherein a ratio of the outer diameter squared to the height of the apparatus is under 21 and wherein a ratio of the weight to the square of the outer diameter times the height is under 0.08.
A method of using a weight-balanced apparatus, comprising:
- inserting at least one hand into a main body shaped substantially like a hollow sphere with spherical caps removed in a same central axis of the body to create two opposing openings sized to account for a natural motion of a user's arm during exercise and where the main body is balanced in each of at least three dimensions from a center point of the sphere, wherein each of the two opposing openings have a continuous, rotationally symmetric, beveled, upper edge around the opening, wherein a ratio of the outer diameter squared to the height of the apparatus is under 21, and wherein a ratio of the weight to the square of the outer diameter times the height is under 0.08;
- grabbing a hand hold traversing centrally through the hollow of the spherical main body through the center point and transverse to the central axis;
- and
- exercising by maneuvering the apparatus using the hand hold as a contact point between a user and the apparatus.
