Abstract: An exercise device including one or more weight stacks moveably supported on a frame. Each weight stack includes one or more weight plates that may be selectively engaged by way of a dial arrangement operably coupled with the weight stack. The dial arrangement is connected with a selection member that extends through a selection aperture in the weight plates. Each selection aperture defines a unique contour with at least one engaging surface, such as a tab. The selection member has corresponding protrusions adapted to engage the engaging surface of the weight plate. Each dial arrangement may be configured so that the weight stack may only be actuated when the selection member is properly positioned so that the protrusions properly engage the engaging surfaces. By adjusting the dial setting, the selection member is rotated so that one or more of the various protrusions engage associated engaging surfaces in order to engage some combination of weight plates. Upon actuation (i.e.

Abstract: A bicep exercising device has a frame with a housing, and a elbow cradle to hold the elbow in a chosen flexed position. The elbow cradle is adjustably attached to a frame and a rotatable handle grip. This allows for comfortable position of the hand in a palm down position and the elbow in a flexed position between about 179 degrees and 15 degrees. The handle rotates 180 degrees or more, thus allowing for full supination of the forearm. Using a supination motion of the forearm a user can exercise the bicep muscle.

Abstract: An exercise machine with a bench press and a pair of weight stacks, which are operationally connected to a lifting bar of a barbell. Pushing motion on the lifting bar transmits the force to a series of wheels connected by flexible bands and to a pair of weight stacks positioned behind the bench press. The weight members of the weight stack are connected by pins, such that upward movement of the uppermost weight members causes pulling force to be applied to successive lower weight members one at a time, thereby allowing incremental increase in the resistance force to the lifting motion of the user.

Abstract: At least one set of weights is arranged into a stack for selective connection to a weight lifting member. On some embodiments, a vertical stack of weights is disposed beneath the weight lifting member, and at least one selector rod is rotatably mounted on the weight lifting member and selectively rotated into engagement with a desired number of the vertically stacked weights. On some embodiments, a horizontal stack of weights is disposed on opposite sides of the weight lifting member, and at least one selector rod is movably mounted on the weight lifting member and selectively moved into engagement with the desired number of horizontally stacked weights. The horizontal stack of weights may be used to supplement the vertical stack of weights, or on an independent exercise device, such as a dumbbell.

Weight selectors are movable into and out of engagement with different combinations of the weight plates to secure a desired amount of mass to the handle. The weight selectors are preferably nested within respective ends of the handle member and accessible via upwardly opening slots in the weight plates.

Abstract: A barbell collar apparatus features an elastomeric, flexible cylinder with a magnetic inner and an outer layer. Magnets are disposed adjacent to the inner layer, in various arrangement embodiments, to selectively secure the apparatus to a bar, typically disposed immediately adjacent to weights chosen, so that weights are retained against shifting and slippage along the bar. The apparatus is spread apart as needed for installation and removal from a bar. The apparatus is provided in pairs. The apparatus is provided in various colors to be easily identified and located. The light weight of the apparatus provides that additions to the weight and bar are negated in figuring the total weight lifted.

Abstract: A resistance assembly for a hydraulic resistance exercise apparatus includes a single-action hydraulic cylinder having a longitudinal axis and extending from a first end to a second end. The single-action cylinder provides resistance to compression of the cylinder, one end toward the other, but provides little or no resistance to extension of the cylinder, one end away from the other. A first compression linkage compresses the hydraulic cylinder in response to movement of a first exercise resistance lever in a first direction. A second compression linkage compresses the hydraulic cylinder in response to movement of a second exercise resistance lever in a second direction directly opposed to the first direction. An engagement exercise lever includes an engagement pin for selectively engaging the engagement exercise lever to move in fixed relation to one or the other the first or second exercise levers in both the first and second direction.
