Every curved Back Stretcher is designed to alleviate pressure on the discs of the spine by moving the spine into extension (the stretching motion over a curved surface). Putting the back into extension is extremely effective in relieving back pain and discomfort. However, putting the back into extension is oftentimes not enough to gain promising results because of the tightness of the surrounding back muscles. Thrival provides a combination of both back stretching and deep tissue pressure. This differs from other back stretchers which do not provide deep tissue muscle relief.

The key to Thrival’s superior deep tissue massage is the narrowness of the arches and the ability to adjust to a person’s body. The narrowness of Thrival’s arches reduces the surface area that your back rests upon, which in turn creates a deeper massage.

Furthermore, it is necessary that the product adjusts to your body so that you can effectively apply the pressure to the right area. The Thrival Back Stretcher adjusts both extremely narrow and wide so that it will fit your body and it can reach any muscle group.

Tight erector muscles, also known as the erector spinae, can cause pain and discomfort in the back. The erector spinae are a group of muscles that run along the length of the spine and they are responsible for maintaining proper posture and supporting the spine during movements such as lifting and twisting.

When the erector spinae muscles become tight, they can pull the spine out of its natural alignment, leading to poor posture and a rounded upper back. This can put extra stress on the spine and lead to conditions such as lower back pain, muscle strains, and even herniated discs.

Tight erector spinae muscles can also limit the range of motion in the spine, making it difficult to perform certain activities such as twisting and bending. This can lead to compensatory movements, which can place extra stress on the spine and lead to further pain and discomfort.

The spine is made up of a series of vertebrae that are separated by discs. These discs act as shock absorbers for the spine and help to distribute the forces of movement and gravity. Over time, the discs can become compressed and lose their ability to effectively absorb these forces, leading to conditions such as herniated discs and degenerative disc disease.

Extension exercises can help to reverse this compression and promote the health of the discs. Laying over a back stretcher creates a pulling force on the spine that helps to decompress the discs by elongating the spine. This can help to reduce pressure on the discs and promote the flow of nutrient-rich blood to the area. Additionally, extension exercises can also help to reduce pain and discomfort caused by compressed discs.
