The transverse abdominis is a deep abdominal muscle that plays a crucial role in core stability. It is located beneath the rectus abdominis and oblique muscles, wrapping around the torso like a corset. This muscle helps support the spine and pelvis, contributing to overall posture and balance. Engaging the transverse abdominis is essential for various physical activities, including lifting and twisting movements. Strengthening this muscle can improve athletic performance and reduce the risk of injury. Exercises like planks and abdominal bracing specifically target the transverse abdominis to enhance core strength.
