Abstract
Apparatus and methods for exercise machines having balancing loads. In one embodiment, an apparatus includes a load guide pivotable through at least one plane of freedom, a load slideably engaged with the load guide, a lift arm having a first end coupled to the load guide, and a cable-and-pulley device. The cable-and-pulley device is operatively coupled to the load and to the lift arm so that a training force applied to the lift arm induces a lift force on the load. The exercise machine requires the user to balance the load as the load is raised, providing a more enhanced workout. In alternate embodiments, the load guide may include at least one rocker engageable with the floor surface, or may be pivotably coupled to a support frame (or base) so that the load guide does not contact the floor surface. In another embodiment, the load guide may include a base having a convex surface engageable with the floor surface, the load guide being pivotable in any direction. In a further embodiment, an apparatus includes a support having a first end proximate the floor, the support being pivotable about the first end, a lift member pivotably coupled to the support, and a load coupled to the lif…
