Various types of exercise equipment designed to provide the user with such aerobic resistance machines have been developed and are well known in the art. For instance, one type of exercise equipment employed by individuals to aerobically exercise the body is free weights or bar bells. While this can provide the user with an excellent form of variable weight resistance and aerobic activity, free weights suffer from several disadvantages. For instance, free weights are both heavy and bulky. Moreover, to perform the different type of exercise presently recommended by physical fitness experts, the user must be able to use the weights in diverse lifting motions, many of which cannot be performed using free weights.
Additionally, the user must either have several weight amounts set up at any given time so that the user can move quickly from one exercise to another, or the user must stop each time and change the weights out for the next exercise—a stop that greatly inhibits the aerobic benefits of the workout.
To overcome these disadvantages, rack weight machines have been provided that are assembled to allow the user to easily move from one weight station to another and quickly set the weight amounts, thereby providing a machine that is capable of delivering a resistance/aerobic workout. However, these machines are also often bulky, heavy, expensive or found in expensive exercise gyms and take up a significant amount of space.
Over the years, exercise machines have undergone vast changes in an attempt to provide the user with an exercise machine that is capable of providing a compact, lightweight form of resistance and simultaneously give the user a good aerobic workout. These devices typically employ diverse forms of mechanical apparatus to achieve these goals, such as bicycling, rowing, jogging, and striding and stair climbing apparatus. For example, U.S. Pat. No. 4,645,200 to Hix; U.S. Pat. No. 4,989,858 to Young, et al.; U.S. Pat. No. 5,104,363 to Shi and U.S. Pat. No. 4,940,233 to Bull, et al.
Some of the more recently developed machines use a resistance that is created by a complex system of electronically actuated brake type devices that are controlled by microprocessors.
Although these systems can provide the user with a resistance and aerobic workout, they suffer from the disadvantage that they are susceptible to mechanical failure and regular maintenance requirements due to their complex integrated mechanical and electronic design. Another disadvantage lies within the positive displacement cylinders that are typically employed in such devices. The positive displacement cylinders generally used are conventional shock absorbing type cylinders. For example, a typical structure of such a device includes a cylinder having a piston disposed therein. The piston having a fluid port there through and attached to a rod extending externally from the cylinder that is mechanically attached to a lever arm. The cylinder has an incompressible positive displacement fluid or oil within the cylinder that is forced from one end of the cylinder to the other via the fluid port in the piston as the piston is reciprocated within the cylinder. During use, the positive displacement fluid's temperature increases due to the friction that is created from the fluid being forced back and forth through the piston's fluid port. Since the fluid is confined to a rather small volume with little surface area, the heat is not easily dissipated from the fluid. Thus, the temperature of the fluid quickly increases and since positive displacement fluids have a positive viscosity index, the heat quickly breaks down the fluid's viscosity. The resistance of the cylinder is thus decreased because the fluid moves more easily through the fluid ports in the piston and the resistance and aerobic benefits to the user are decreased as well. Moreover, the lower viscosity may also cause the fluid to leak from the seals in the cylinder.
Another disadvantage of the conventional exercise positive displacement systems is that the fluid ports cannot easily be adjusted to change the resistance of the positive displacement system. Typically, to change the resistance, the user must interrupt his exercise routine and manually adjust the mechanical advantage of the lever arm with respect to the cylinder to either increase or decrease the resistance. This interrupts the user's aerobic activity and therefore decreases the effectiveness of the exercise routine.
Additionally, a number of other disadvantages exist including:
One aspect of the present embodiment may take the form of an improved exercise machine.
Over the last two decades, emphasis has been placed on the benefits of an aerobic workout, which most importantly, offers protection from cardiovascular disease. Accordingly, several advantages of one or more aspects of the present embodiment are as follows:

In this embodiment handle 22 may be made with coated wire fabricated with material that has cushioning properties thereby minimizing any pain that may be experienced in grasping the handle 22. However, other materials may be suitable including: vinyl, polyurethane, and leather.
In another embodiment the handle 22 having holding parts with both sides of holding parts forming an arc strengthening support with distal ends registering into parallel holes 16,17 (
In this embodiment pump 4 and pump 3 may be dual action pumps manually driven that respectively operate in tandem with each other during each pumping stroke.
Operation
The embodiments disclosed herein provide a compact exercise machine having a flexibility to attach the exercise machine to fixed, non-fixed and moveable objects. The exercise machine is easily transported with the use of the exercise machines lever or handle effectually secured to the compact exercise machine, which may be carried and utilized under the weight of the exercise machine. The exercise machine may attach to various types of furniture and the exercise machines structure and handle greatly facilitates the operation of the compact exercise machine. The new, or different compact exercise machine can be constructed to include benefits over conventional compact exercise machines, such as smoother or improved use of exercise machine while reclining or sitting. Improved performance in operation requiring less force or effort by a user can be particularly important in exercising for weakened or less-able users, such as in a medical or hospital setting, or a retirement home. Additional environments are envisioned. The new, different, or variables can otherwise have required a structure, as described herein, which may have necessitated a structure(s), and thus, an unfamiliar part, method, or movement of the exercise machine for the user.
The current disclosure improves the construction by accounting for the new or different structures while providing the user the familiar operation and exercise routines. To the extent not already described, the different features and structures of the various embodiments may be used in combination with each other as desired. That one feature may not be illustrated in all of the embodiments is not meant to be construed that it may not be, but is done for brevity of description.
It can be appreciated that at least one embodiment of the exercise machine may also be utilized to provide a more dependable, compact, yet economical device that may be used by persons of almost any age. Various modifications to the disclosed embodiments will be readily apparent to the reader, and the general principles defined herein may be applied to other embodiments and applications without departing from the spirit and scope of the present embodiment. Many other variations are possible. For example:
