Which muscle group is primarily targeted during a back massage?

The erector spinae muscles are the primary muscle group targeted during a back massage because they are responsible for extending and stabilizing the spine. This group consists of three main muscles running along the length of the back, from the lower back up to the neck. A back massage typically focuses on relieving tension and promoting relaxation in these muscles due to their central role in posture and spinal alignment.

When a massage therapist works on the back, they apply techniques that can help to decompress the spine, enhance blood flow, and alleviate tightness in the erector spinae. This contributes to reducing discomfort and improving range of motion in the back, making it a primary focus during a back massage. The other muscle groups mentioned, while they may be involved in various aspects of back function or adjacent areas, do not specifically represent the main target area for a back massage.
