Description

SUPPORTIVE EXERCISE DEVICE

BACKGROUND

Field of the Invention

The present invention relates to the field of exercise equipment. More particularly, the present invention is directed to a device that promotes correct posture when performing exercises, such as those performed in various yoga disciplines.

Description of Related Art

A variety of exercise devices are known in the art for assisting or guiding a user in proper exercise technique. Of such devices, many are directed to conventional exercises, such as sit-ups and weight-lifting, or the like. Although yoga is practiced by millions of people worldwide, few devices are available for assisting and guiding a user in proper technique.

Moreover, the modern, sedentary lifestyle is causing an out of proportion crisis. Lack of activity, combined with sporadic overexertion causes damage to our anatomy, including the spinal disks which compress and bulge, resulting in pain and predisposition to further injury. Such damage is typically masked by anti-inflammatory and analgesic medications, without addressing the root cause.

Poor posture is at epidemic proportions, begins in childhood, and continues through adulthood in our workplaces. Applicant recognizes that workplaces are plagued with lost productivity and absenteeism. Disorders related to poor posture account for 60% of workplace disabilities, and the terms "spinal injury" "computer posture", "computer neck posture", and "carpal tunnel syndrome" are common terms these days. Applicant recognizes that aging populations transcend these conditions into retirement. Deprived of comfort and mobility, dreams of freedom, recreation and travel are replaced with appointments to cure their pain and disabilities. As a result, healthcare systems are overwhelmed and billions of dollars are spent on treatment, addictive pain medication and their toxic side effects. Accordingly, the costs for medical benefits and insurance plans are at a breaking point.

Applicant recognizes that medications simply mask pain, while massage, other passive therapies and special pillows can help release tightness, but regular activity is needed to get stronger and bring about long term changes in habits. One can lower one's risks and help preserve collective healthcare resources by protecting one's body mechanics. Sources of chronic pain can be overcome. Good posture reduces risk factors for problems such as osteoporosis, myofascial pain, fibromyalgia, arthritis, TMD, chronic headaches, carpal tunnel syndrome, back, hip and neck pain, breathing problems, incontinence and many more maladies. The best solution is to transform one's awareness about one's body condition and restore healthy movement in daily living.

There remains a need in the art for devices that are inexpensive and easy to make, that aid users in achieving strength and flexibility. The present invention provides a solution for these problems.

SUMMARY OF THE INVENTION

The purpose and advantages of the present invention will be set forth in and apparent from the description that follows. Additional advantages of the invention will be realized and attained by the methods and systems particularly pointed out in the written description and claims hereof, as well as from the appended drawings. To achieve these and other advantages and in accordance with the purpose of the invention, as embodied, the invention includes, in one aspect, a supportive exercise device adapted and configured to assist a user in achieving and maintaining an exercise posture, the device comprising a seat adapted and configured to be placed under a user, a support frame extending upwardly from the seat, a backrest carried by the support frame, and shoulder straps carried by the support frame, adapted and configured for maintaining the user's shoulders in a predetermined position.

The supportive exercise device can further include an angle adjustment mechanism in connection with the support frame, adapted and configured to adjust a position of an upper end portion of the support frame, and thus also the shoulder straps.
