In flat back posture, which muscles are typically long and weak?

• A. Hamstrings
• B. Hip flexors
• C. Neck extensors
• D. Rectus abdominis

Answer: (B)

In flat back posture, the hip flexors are typically long and weak due to the position of the pelvis and the lumbar spine. In this posture, the pelvis tilts posteriorly, which can stretch the hip flexors, placing them in a lengthened state. This lengthening can lead to a decrease in muscle engagement and strength, causing weakness in the hip flexor group. Muscles that are long and weak often lack the proper strength and activation to support optimal alignment and function, which can lead to compensatory movement patterns and potential injury. In flat back posture, this weakness can contribute to stiffness and imbalance throughout the lower body and lumbar region as the body struggles to stabilize itself. Understanding this aspect of flat back posture highlights the need to strengthen the hip flexors while maintaining balance with opposing muscle groups to promote better alignment and function in movement.
