## Title
Weight training barbell system

## Abstract

A weight training barbell system provides modifiable barbells that facilitate the attachment of plate weights, various elastic straps, inelastic bands, handles, grips, and connectors, in a compact space saving design. The weight training barbell system incorporates various features that allow it to perform specialized exercises that provide same or greater intensity from a workout using lower weights. The weight training barbell system accomplishes this through the use of specialized components that permit a user to redistribute weight along the length of the bar and components that add resistance, in more than one direction, while lifting the bar. The weight training barbell system can be utilized to perform compression lifting exercises, offset lifting exercises, and self spotting exercises.

## Background
The current application claims a priority to the U.S. Provisional Patent application Ser. No. 61/823,077 filed on May 14, 2013.


FIELD OF THE INVENTION
The present invention relates generally to personal exercise equipment and more specifically to an apparatus, system and method for its use that enables an individual to simultaneously lose weight and build or tone their muscles
BACKGROUND OF THE INVENTION
It is estimated that 67% of the American population, or 210 million people, are currently overweight and a rising percentage of people around the world are also afflicted with this condition. Aside from a poor diet, studies suggest the reasons for this trend are increasingly busy lifestyles and decreased physical activity. There are numerous exercise devices and fitness programs on the market that are designed to help people lose weight and increase their fitness level. The drawbacks to most of these devices are that they take up a lot of space, are expensive and provide either weight training or aerobics, but not both. The current invention is an affordable, compact, portable exercise system that combines weight training and aerobic exercise. Many of the exercises performed with the invention actually provide weight training and aerobics simultaneously. This saves the user time as compared to performing weight training and aerobic exercises separately. The current invention is also multifunctional, which eliminates the need for users to purchase and store weight lifting equipment and aerobic equipment such as treadmills or ellipticals.
Another challenge to maintaining a regular exercise program over a long period of time is a lack of variety. People become bored of performing the same exercise over and over. For instance treadmills are effective for cardio, but they have a singular function.
Consequently, most people tire of just running on a treadmill several days per week for a period of years and simply quit doing it. Also, when the same exercise is performed repetitively the body adjusts to the movements, making the exercise less and less effective. To experience gains with less flexible equipment such as weight machines and treadmills, the user is forced to either extend the duration of the exercise or increase the weight. The disadvantage of extending the exercise is that it becomes more and more time consuming and the disadvantage to increasing weight is that it increases the chance for injury.
A principal advantage of the current invention is that many of the exercises allow the user to isolate particular muscles using a feature called “self-spotting”. With many of the exercises the user can employ a technique called self-spotting. This is where the user performs a one-handed exercise and uses the other hand to assist with the exercise. The advantage to self spotting is that the user can perform exercises with heavier weights. When the target muscle begins to fatigue they can smoothly perform several more repetitions using the other hand for assistance. The “spotted” repetitions are the most effective in breaking down the muscle, which causes it to grow. Self spotting cannot effectively be performed with standard dumbbell weights because there is no extension to grab with the free hand.
Several inventors have attempted to address these issues with various devices such as; U.S. Pat. No. 8,267,841 B2 to Michael Allison and Kasper Allison shows a kettle bell shaped apparatus that allows different size dumbbells to be attached to it. This device provides users with existing dumbbells the ability to also have variable weight kettle bells, without having to purchase kettle bells of each size. The current invention has a similar capability when the optional single grip handles are attached to the dumbbells. The difference between the Allison invention and the current invention is that the connection between the handle and the dumbbells is not rigid with the current invention. Also, Allison's invention has one purpose, whereas the current invention is multifunctional.
U.S. Pat. No. 5,518,486 to Sheeler (1996) has a similar use as the current invention when the current invention uses the optional inelastic foot strap. However Sheeler's invention is primarily designed for stretching whereas the current invention is designed for weight lifting, cross training, yoga and stretching. Sheeler's device includes a single grip handle at the top, an adjustable inelastic connector strap and a foot loop at the bottom. The device can be used for some aerobic exercises but is limited in its use because it lacks the capability of adding weight to the handles. Once the user's body has adjusted to the maximum level of resistance the device can provide, which is the user's own body weight, the device becomes limited in its effectiveness. Also, the device has a single handle for each hand. This limits the number of different exercises that are possible with the apparatus and limits the amount of resistance the user is able to transfer to their muscles. In contrast, the current invention can be used with a single bar or it can be used in a similar manor to Sheeler's by using two bars.

Additionally, the weight training barbell system allows elastic bands to connect two dumbbells to each other, as well as allowing the dumbbell to be connected to the foot sling. The bands can be used as the primary source of resistance to the dumbbell bars or can provide additional resistance when weights are used with the dumbbells(s). Through these various features, the present invention is able to combine weight training of a primary muscle, weight training of a secondary muscle, strengthening of the core, strengthening of the abdominal muscles, aerobics, muscle toning and weight lifting. The present invention can be utilized, with little modification for use in existing dumbbell training and aerobic exercise systems conducted in a group workout setting.
The weight training barbell system allows a user to perform compression lifting exercises through the attachment of the at least two compression collars. The at least two compression collars are sleeved over the first end and the second end of the bar. Each of the at least two compression lifting handles permit the user to engage the barrel grip and compress their hands towards each throughout various lifting exercises. A handle spring positioned within each of the compression lifting handles provides resistance to the user. The benefits of using the compression lifting handles for compression lifting exercises comprise elevating the user's heart rate by 20%-30% compared to non-compression, increasing calories burned; maximizing time under tension of a lift; working muscles in two directions simultaneously increasing the muscle building benefits of a lift; providing the muscles already under complete tension intensifying a lift and building more muscles; providing more effective burn compared to non-compression lifting exercises; providing a tighter feel to the muscles for a longer period of time compared to non-compression lifting exercises; permitting a user to get the same or greater intensity from their workout with less weights, reducing likelihood of injuries; reducing the likelihood of the user “plateauing” in their workout routine because they are working muscles against each other; and engaging a majority of the muscle groups in the user's core and abdomen for a more complete total body workout.
The weight training barbell system allows a user to offset weights on the bar permitting the user to perform offset lifting exercises. Offset lifting exercises are characterized by the user shifting the weight on the bar to one side creating a dominant hand and a passive hand. The use would be able to adjust the hand positioning and the weight distribution in order to find the ‘sweet spot’ for the dominant hand. The benefits for the offset lifting using the weight training barbell system comprise: working one side of the body at a time is more effective because it decreases synergy that is created with a symmetrical lift, making the lift more concentrated and intense; allowing the user to target specific muscle groups to work out after finding the ‘sweet spot’ for the dominant hand; allowing less weight to be used during lifting exercises since only one side of the body is being worked out, reducing the likelihood of injuries and long term joint wear; and providing a means of combining the exercises with self spotting exercises in order to enhance the muscle breakdown/building effects.
The weight training barbell system is provided as being cost effective, compact, and portable. The portability of the present invention is accomplished through its space saving design. A benefit of the portability is that the present invention can easily be transported for use in various group workout settings popular at most gyms.
The weight training barbell system combines aerobic and weight training exercises that work a multitude of muscles at the same time such as the biceps, quadriceps, gluts, abdominals, back, core and the cardiovascular system. The present invention can be implemented in a multitude of cross-training exercises. By being able to provide variety to the user, the present invention is able to provide a wide variety of exercises the user can execute, which prevents the user from getting bored and from either reaching a plateau or stopping their regimen. The present invention is versatile and facilitates the addition of different amounts of weight to the bar permitting the resistance to match the user's fitness/strength level. Through the use of the attachable components, the present invention can incorporate a foot sling in order to perform various exercises that are effective in strengthening the back muscles, which will help improve a user's posture.
Many of the present inventions exercises can employ a technique called “self-spotting”. Spotting is where a partner assists the user with the last few reps of a set and is used by serious weight lifters. If the user is lifting the proper weight their muscles will be completely fatigued at the end of the set and it will be difficult for them to complete the last few repetitions. With the help of the spotter the user can complete the last few reps, and maintain proper form doing them. The last few reps of each set are the most effective because more micro trauma is achieved to the muscles (tears to tiny muscle fibers) and the body responds to the damage by increasing the amount of protein going into the muscle, which causes it to grow. Without the spotter the user will be forced to use their body weight to complete the last few reps. This diminishes the effectiveness of completing the exercise with proper form and increases the chance for the user to injure them self. Through the particular features of the present invention, the user would be able to lift the bar with one hand and use the other hand to “self-spot” the weight. When the user becomes fatigued they just provide more assistance with the secondary hand.
There are two methods for executing the “self-spotting” technique. First, when performing a standard two arm bicep curls with one bar, the user shifts the bar to one side on the way up and uses the opposite hand for assistance. This is possible because the weights are in the center of the apparatus, between the two hands. The other self-spotting method occurs when the user grips the rotating center hand grip and performs a standard one handed arm curl. When the user's arm begins to fatigue at the top of the rep they can use their free hand to push on the bar to completion.
With the weights being located between the user's hands, rather than to the outside, the center of gravity of the apparatus is centralized to the user's core. This makes the bar much easier to balance than a standard barbell, where the weights are to the outside of the user's hands. With the centralized weights a much wider variety of cross-training, strength training and aerobic exercises can be performed. Essentially, the weights can be thrown around without the user losing their balance.
Using the various bars, bands, straps and handles, and various combinations of assemblies with these accessories, the present invention can be used to perform hundreds of exercises. This eliminates the need for the user to purchase multiple exercise apparatus's.
