The back support exercise primarily focuses on which muscle groups?

The back support exercise is designed to engage the shoulder extensors and hip extensors significantly. The movement typically requires maintaining a strong and stable posture while supporting the body weight, which necessitates recruitment of these muscle groups for optimal performance.

The shoulder extensors, such as the latissimus dorsi and teres major, play a crucial role in stabilizing the shoulder joint and facilitating the movement of the arms in conjunction with the body. Simultaneously, the hip extensors, primarily the gluteus maximus, work to maintain pelvic stability and proper alignment of the spine during the exercise, ensuring that the back remains supported.

This exercise not only strengthens these key muscle groups but also promotes core engagement, which is essential for overall stability. The focus on shoulder and hip extensors helps develop a strong foundation for both functional movements and athletic performance while also enhancing postural alignment.
