Abstract: A fitness machine enabling several lunge and squat-style exercises comprises a frame that provides the basic structure of the machine. The frame includes a set of horizontal beams and a set of vertical beams creating a rectangular interior exercise space for a user to stand. A handle is included with each horizontal guide rail that slides forward and backward along the horizontal guide rail. The horizontal guide rail is movably connected between two of the vertical guide rails such that the horizontal guide rail freely slides up and down the vertical guide rails, ensuring that the horizontal guide rail maintains a parallel relationship with the floor throughout the entire range of motion during use. The handles and the horizontal guide rails significantly improve the user's balance during the exercise, eliminating unnecessary stress on the knees, hips, and lower back.

Abstract: An exercise machine. The machine includes a frame with front and rear upper support beams. Guide rails span between the two support beams and are connected thereto. Right and left handles are configured to slide back and forth along the length of the guide rails between the front and rear support beams. During operation of the machine, a user grabs the handles and moves them back and forth in a swinging motion that mimics traversing a set of monkey bars. The guide rails may be arranged in a non-parallel configuration to provide a more natural path for the user's hands during operation and to reduce unwanted stress on the user's shoulders by limiting handle movement along the path to accommodate a more comfortable range of motion.
