Abstract: An exercise machine, more specifically, an abdominal exercise machine. The abdominal exercise machine consists of a frame upon which the user sits, the frame having a support arm tilted backward from vertical with the lower lumbar region against a seat member. Pivotally attached to the frame is an upper seat rest assembly that has a pair of handles and a pad designed to lay against the upper back of the user. The seat back assembly moves with the upper body of the user, the hands of the user assisting in maintaining the upper seat back member against the upper back, while the user moves from a tilted back position to a crunch position, and simulating a traditional sit-up movement.

Abstract: An exercise machine including a frame and a drive arm pivotedly engaged to the frame, for example, on an upright thereof. A cylinder is mounted at one point to the frame and, at a removed end of a plunger, has links or rod members to engage the removed end of the plunger to the frame and also to the drive arm.

Abstract: An internally illuminated sign includes an elongated housing defining an interior chamber. The housing has opposite end portions, at least one side portion and an elongated member disposed between the opposite end portions. The side portion includes instructional indicia and permits the transmission of light therethrough. A plurality of induction lamps are disposed in the interior chamber and are connected to the elongated member. The induction lamps are spaced apart along a longitudinal direction.

Abstract: An exercise machine which includes a frame which is connected to a series of pivotable links. A user sits on one of the links and applies force, typically with his legs, to a drive link. At least two of the links are connected by some form of resistance, such as hydraulic cylinder. When the user presses against one of the links, resistance is applied, through the links, by the weight of the user and the hydraulic cylinder.
