The invention is related generally to exercise devices utilizing elastic restraint straps and loops, and more particularly, to a unitary exercise device that provides counter-balancing resistances to exercise the core muscles and legs of a user over a full range of motion in performing various physical activities, such as running, walking, cycling, skating, skiing, and other like physical activities.
Today, running is one of the most popular forms of exercise in the United States. There are many benefits of running: improving cardiovascular fitness, building up strength, endurance, and stamina, burning calories and controlling weight, etc. Running may take several forms, including jogging or steady-state running that utilizes slow twitch muscles to build endurance and aerobic fitness, and sprinting which involve anaerobic workouts that improve muscle strength as well as speed and endurance. These two forms can be combined to improve the user's performance over time to overcome plateaus or sticking points in training.
For persons less athletically inclined, advanced in age, or undergoing rehabilitation of injuries or after surgery, these persons instead of running may prefer walking, which will still provide similar benefits as running but at a different level of effort and intensity. In general, training one's body to run or walk longer or faster takes time, patience, and perseverance in that these persons should train for the long term and not physically overstrain their bodies beyond their current physical capabilities. Many runners/walkers may hit an early plateau in their training plans or may suffer burnout, fatigue, or simply lose interest in any further training if they try to progress too rapidly.
Accordingly, many varieties of devices and apparatus have been developed to aid persons engaged in running, walking, bicycling, etc., or for that matter, any physical activity that utilizes large muscle groups such as core muscles and legs in a coordinated, repetitive cyclic pattern. Many of these apparatus and devices utilize resistance bands or elastic restraint straps to apply resistance to the core muscles or legs of the user while exercising. For example, a leg muscle training device comprising an elongated elastomeric and stretchable tether and a set of leg binders attached to each end of the tether is disclosed in U.S. Pat. No. 5,167,601 to Frappier, entitled Sprinter Leg Muscle Training Device and Method. In Frappier, stationary resistance is provided to a runner by a personal trainer firmly grasping one end of the tether or attaching it to a point of attachment. Polyurethane surgical tubing may be used for the tether.
There are also numerous apparatus utilizing treadmills with resistance bands or elastic restraint straps. For example, a treadmill with a frame connected at a rearward end of the treadmill wherein a resistance attachment having an end connected to a human body is affixed to the frame of the treadmill so as to exert a resistance force on the human body is disclosed in U.S. Pat. No. 6,123,649 to Lee et al., entitled Resistance Application for Connection to a Human Body. Another example of an apparatus utilizing a treadmill is found in U.S. Pat. No. 6,652,427 to Wroclawsky, entitled Treadmill Resistance Apparatus, which discloses an apparatus for use with a treadmill for exercising the legs and lower body of a user with an elastomeric member that attaches to the user.
Another common type of exercise apparatus utilizing resistance bands or elastic restraint straps are those that utilize either a waist belt or various harnesses with mating clips that are attached to a body of a user to establish anchor points, wherein elastic cords are attached to the mating clips and then connected to various straps or harnesses placed around various parts of the user's body, such as an elbow, arm, foot, thigh, etc. An example of such an exercise device is disclosed in U.S. Pat. No. 7,608,026 to Nicassio, entitled Device for Strengthening, Training, and Rehabilitating Isolated Muscle Groups Using Elastic Resistance Elements. A similar type of exercise apparatus that is directed a specific physical activity is disclosed in U.S. Pat. No. 7,314,437 to Frappier, entitled Training Harness for Athletic Hitting and Swinging Skills.
As these examples indicate, many of these exercise apparatus require additional elements that may render the exercise apparatus more cumbersome and thus less useful in practice as well as more expensive to produce. Moreover, an exercise apparatus may be usable only for running, walking, or the like, while another exercise apparatus may be designed for a different physical activity, such as hitting or swinging movements in baseball, softball, or golf, and may require additional elements making the exercise apparatus even more cumbersome and expensive to produce. In other words, an exercise apparatus should be able to be utilized by a user in as many different physical activities as practicable.
In view of the foregoing, there is an ongoing need for an exercise device that utilizes resistance bands or elastic restraint straps that is unitary and self-contained in that it does not require additional elements or parts. It should also be easy and inexpensive to produce each such device so that each and every potential user will have an exercise device that exactly matches his or her present physical characteristics and capabilities and meets the needs of their intended training program. It would also be advantageous if the exercise device would be capable of being used in the performance of or training in numerous physical activities other than being limited simply to running, walking, or cycling.
To address the foregoing problems, in whole or in part, and/or other problems that may have been observed by persons skilled in the art, the present disclosure provides a unitary exercise device comprising a plurality of resistance bands and/or elastic restraint straps to generate simultaneous counter-balancing tensions to the large muscle groups such as the core muscles and legs of a user while the user is undergoing various physical activities.
An exercise device in accordance with the invention is unitary and self-contained; that is, the exercise device is capable of being used by a user without any additional equipment or accessories and is customized and produced specifically for each user individually. Thus, there is “no one size fits all,” although there may be small, medium, and large sizes of the exercise device such that each fits a relatively large group of users.
An exercise device in accordance with the invention comprises the following: (a) an elastic waist loop or belt; (b) an elastic left thigh loop; (c) an elastic right thigh loop (d) an elastic left rear strap having a first end and a second end; (e) an elastic right rear strap having a first end and a second end; (f) an elastic left front strap having a first end and a second end; and (g) an elastic right front strap having a first end and a second end. All of the elastic loops and straps in an assembled exercise device may be sewn together where necessary (with bonded nylon or bonded polyester threads) or heat fused together.
In assembling the exercise device, the first ends of the elastic left rear strap and the elastic right rear strap may be anchored together and connected at the middle of the back of the elastic waist loop and then the second end of the elastic left rear strap may be connected to approximately the middle of the rear of the left thigh loop and the second end of the elastic right rear strap may be connected to approximately the middle of the rear of right thigh loop. To complete the assembly, the first end of the elastic left front strap may be connected to the front of the elastic waist loop, slightly offset to left of center, and the first end of the elastic right front strap may be connected to the front of right thigh loop, slightly offset to right of center. Likewise, the second end of the elastic left front strap may be connected to approximately the middle of the rear of left thigh loop and the second end of the elastic right front strap may be connected to approximately the middle of the front of the right thigh loop.
As for the material used for the elastic waist loop, the elastic left and right thigh loops, and the left and right rear and front straps, there are many types of material available from online wholesalers, such as, for example. DirecTex located in Commerce. California. The material may take the form of webbing, cord, or bungee. Elastic webbing may be made from nylon, polypropylene, or polyester and is available in widths that can range from ⅜″ to 4″. Elastic webbing may be braided, knitted, or woven, and one wholesaler recommends woven elastic for waistbands because woven elastic retains its width when stretched. As for the elastic straps, nylon and polypropylene webbing each have different weights as well as different widths and accordingly the exercise device can be produced with the desired resistive force by varying the thickness, weight, length, or width of the webbing. Industrial sewing thread is also available to provide the required strength for the sewn connections of the final exercise device.
Once the desired webbing is selected, an exercise device can be produced as a unitary exercise device that can be worn over athletic wear or under, the latter being useful when exercising outdoors or in inclement weather. In other embodiments, the exercise device can be integrated into athletic wear; as an example, the waistband may be incorporated into the waistband of a pair of running shorts, with the left and right thigh loops sewn into the left and right pant legs, respectively, of the running shorts.
A method of using the exercise device in a particular physical activity, which may be sprinting or jogging, swinging a golf club or throwing a baseball, or even beginning physical therapy by walking, is also disclosed. Obviously, a serious experienced user in a particular physical activity may likely devise their own exercise program, perhaps with the help of a professional trainer. However, for the average user, whether for a recreational activity or rehabilitation, there are certain principles that may be applicable to utilization of a unitary exercise device in accordance with the invention. An object of the invention, in general, is to help train a user to move his or her body, e.g., walk or run, faster than he or she normally does so that eventually he or she will be able to eventually run or move faster without the unitary exercise device. As for other physical activities, such as swinging a golf club or a tennis racket, the desired improvement may be a faster speed of a golf ball struck from the head of the golf club or a tennis ball from the head of the tennis racquet.
In general, methods and techniques of utilizing a unitary exercise device may incorporate techniques borrowed from high-intensity resistance or interval training, one of which is that training with a unitary exercise device may be three times a week with alternative days of training without the unitary exercise device or no training at all. In other words, training with a unitary exercise device too hard and too often may slow down results and lead to injuries.
To avoid this, methods and techniques of utilizing a unitary exercise in accordance with the invention device may include measuring the metrics of the performance of a physical activity. For example, a runner or bicycle rider wearing a unitary exercise device generally just needs to measure his time over a specified course and compare times with the unitary exercise device to times without the unitary exercise device. For more complex physical activities, such as hitting a golf ball, the physical activity is more complex and there are more metrics that can be measured. An example of an aid in determining these metrics is the Swing-Caddy SC300i Launch Monitor, which can measure the carry/total distance, smash factor, launch angle, swing speed, apex (maximum height), and ball speed of a driven golf ball. The Launch Monitor is set up near the golf ball and sends the measurement data to an app on the user's cell phone. For other sports involving striking a ball or puck, another device that is available to measure ball speed is the Pocket Radar™ Ball Coach Speed Training Tool and Radar Gun.
Other devices, systems, methods, features, and advantages of the invention will be or will become apparent to one with skill in the art upon examination of the following figures and detailed description. It is intended that all such additional systems, methods, features, and advantages be included within this description, be within the scope of the invention, and be protected by the accompanying claims.

As shown in
All of the elastic loops and straps of the assembled exercise device of

The elastic left and right rear and front straps of the unitary exercise device 100 provide counter-balancing resistive forces to the front and rear of the left and right legs of the user 12 via the elastic left thigh loop 18 the elastic right thigh loop 20, respectively. This results in a bias toward a faster rate of movement of the legs of a user when performing the exercise, in this instance, running, in a controlled, repetitive manner over an extended period of time. That is, the unitary exercise device 100 is used as a type of high-intensity resistance interval training device, in order to improve speed, endurance, and stamina while subsequently running without the assistance of the unitary exercise device.
That is, the unitary exercise device 100 is designed to train the user to move faster in performing a particular physical activity using counter-balancing resistance assistance, which could be characterized as utilizing rebound energy or the trampoline effect to make the user perform faster than otherwise when training. Another method of high-intensity interval training is downhill running, which forces the user's body to move faster rate than it otherwise could do on its own. The disadvantage of downhill running is that this type of running is more prone to causing injuries because there is a tendency for the user to run too fast. In contrast, using the unitary exercise device allows the user to utilize the resistance forces in more controlled manner that is more efficient and safer. Once the user removes the unitary exercise device muscle memory enables the user to run faster than previously.
Turning to
Once the user is satisfied with his unitary exercise device in decision step 606, the process proceeds to step 610, where the user undergoes training with his selected exercise routine while wearing his unitary exercise device. While performing his exercise routine, the user at the same time is measuring his performance for the exercise routine; for example, for basic running or cycling, the applicable metric typically is just the elapsed time to complete a specific distance. For measuring a golf swing, there is the aforementioned Swing-Caddy, and for crunches and sit-ups, the metric may be simply the number of repetitions performed within a specific time period.
The next step is optional step 612, which merely recommends or suggests that the user not repeatedly exercise using only the unitary exercise device. In step 614, the user undergoes training with his selected exercise routine without wearing his unitary exercise device while at the same time measuring his performance for the exercise routine. In decision step 616, the user looks at the metrics from exercising with and without the unitary exercise device and makes a determination whether to continue with his current exercise program; if so, he continues back to step 610. Otherwise, the process ends at step 618, whereupon the user has several options, such as, for example, modifying his exercise routine or modifying his unitary exercise device. e.g., by increasing the tension of the rear and front elastic straps.
In an example of a user utilizing a unitary exercise device, a week-end type golfer used such a unitary exercise device in practicing his golf swing at a driving range. His practice routine was to hit approximately 50 golf balls while wearing the unitary exercise device in a single practice session. Using a Swing-Caddy Launch Monitor, the user found that his driving distance with a driver improved from approximately 216 yards to approximately 260 yards. As expected, when practice time was reduced, the driving distance decreased to approximately 245 yards.
