The transverse abdominal muscle (TVA), also known as the transversus abdominis, transversalis muscle, and transversus abdominis muscle, is a deep abdominal muscle. It is the deepest of the flat muscles, layered on top of the internal obliques. The TVA is a broad paired muscular sheet found on the lateral sides of the abdominal wall. It is an important core muscle that helps to stabilize the spine and protect the body from injury.

The transverse abdominal muscle is the deepest abdominal muscle
The transverse abdominal muscle, also known as the transverse abdominis, transversalis muscle, transversus abdominis muscle, or TVA, is the deepest abdominal muscle. It is a deep abdominal muscle and an important core muscle. It is the only abdominal muscle with muscle fibres running side to side, rather than vertically or horizontally.
The transverse abdominal muscle is a muscle layer of the front and side abdominal wall, layered below the internal oblique muscle. It arises from the inguinal ligament, iliac crest, the inner surfaces of the lower six ribs, and the thoracolumbar fascia. It is innervated by the lower intercostal nerves, the iliohypogastric nerve, and the ilioinguinal nerve.
The transverse abdominal muscle has several functions. It helps to stabilise the trunk, maintain internal abdominal pressure, and support the spine. It also assists in exhalation, compressing the ribs and viscera to provide thoracic and pelvic stability. Additionally, it plays a role in withholding bowel movements, facilitating contractions during labour, and pushing during childbirth.
The transverse abdominal muscle is important in treating and preventing back pain. It helps to stabilise the spine and protect it from injury. Strengthening the transverse abdominal muscle can be achieved through exercises such as the vacuum exercise or the abdominal draw-in manoeuvre.

It is also known as the body's natural corset muscle
The transverse abdominal muscle, also known as the transverse abdominis, transversalis muscle, transversus abdominus, and transversus abdominis muscle, is a muscle layer of the front and side abdominal wall. It is the deepest of the flat muscles, layered on top of the internal oblique muscles. The transverse abdominal muscle is also known as the body's natural "corset muscle" due to its horizontal orientation around the abdomen, similar to a corset. It is the only abdominal muscle with muscle fibres that run from side to side, rather than vertically or horizontally.
The transverse abdominal muscle wraps around the torso, connecting to the rib cage and ending at the middle line of the abdomen. It is responsible for maintaining normal abdominal tension and increasing intra-abdominal pressure, which helps support internal organs and viscera. This muscle also assists in forced expiration, micturition, defecation, and the final stages of childbirth.
The transverse abdominal muscle is a crucial component of the body's core, working alongside the back muscles to provide stability and balance. It is particularly important for spinal health, as it helps to protect and stabilise the spine during everyday movements. A strong transverse abdominal muscle can contribute to better posture and reduced back pain.
The most well-known method for strengthening the transverse abdominal muscle is the vacuum exercise, which involves sucking in the gut while performing tasks such as deadlifts or pull-ups. This exercise helps to improve core stability and can lead to a stronger, more stable spine.

It is responsible for maintaining normal abdominal wall tension
The transverse abdominal muscle (TVA), also known as the transverse abdominis, transversalis muscle, transversus abdominus, and transversus abdominis muscle, is a muscle layer of the front and side abdominal wall. It is the deepest of the abdominal muscles.
The transverse abdominal muscle is responsible for maintaining normal abdominal wall tension. It wraps around the abdomen, creating a "cinching" effect, and is often referred to as the body's natural "corset" muscle. This muscle is important for spinal health and stability, as well as for improving posture and decreasing back pain.
The TVA is also responsible for increasing intra-abdominal pressure, which helps to support internal organs and viscera. This increase in pressure is essential for various bodily functions, including breathing, coughing, and childbirth.
A weak TVA can result in an inability to hold in the stomach, particularly after a large meal or when gassy, as well as lower back fatigue after prolonged standing or walking.
To strengthen the TVA, specific exercises such as the vacuum exercise or the abdominal draw-in maneuver can be performed. These exercises help to activate and strengthen the TVA, improving its ability to maintain abdominal wall tension and provide stability to the spine and pelvis.

The TVA helps to compress the ribs and viscera, providing thoracic and pelvic stability
The transverse abdominal muscle (TVA), also known as the transverse abdominis, transversalis muscle, transversus abdominus, and transversus abdominis muscle, is a muscle layer of the front and side abdominal wall. It is the deepest of the flat muscles and is layered below the internal oblique muscle.
The TVA is also responsible for stabilising the spine and pelvis during lifting movements. It contracts involuntarily during many lifts, acting as the body's natural weightlifting belt. By creating hoop tension around the midsection, the TVA helps to reduce vertical pressure on the intervertebral discs, protecting the spine from injury.
Additionally, the TVA contributes to maintaining normal abdominal wall tension and supporting internal organs. It wraps around the abdomen like a corset, pulling in what would otherwise be a protruding abdomen. Training the TVA can help achieve a flatter belly, improve posture, and reduce back pain.
The most well-known method of strengthening the TVA is the vacuum exercise, which involves sucking in the gut during exercises such as deadlifts or pull-ups.

It is important in treating back pain
The transverse abdominal muscle (TVA), also known as the transverse abdominis, transversalis muscle, and transversus abdominis muscle, is a muscle layer of the front and side abdominal wall. It is the deepest abdominal muscle and is positioned immediately deep to the internal oblique muscle.
The TVA is vital to back and core health. It has been shown to contract and steady the lower back and spine, providing "squeezing support" for the back. This is similar to squeezing a tube of toothpaste and seeing the other end of the tube straighten out. A group of physical therapists in Australia found that whenever we think about moving our arm or leg muscles, the TVA contracts and steadies the lower back.
In people with back pain, the TVA loses its ability to contract and take pressure off the spine. This is one reason why the TVA is important in treating back pain. Many physical therapists base their treatments for low back pain around strengthening the TVA for stability. A weak TVA can contribute to low back pain and lumbar instability.
There are many effective ways to exercise the TVA. The most well-known method is the vacuum exercise, which involves sucking in the gut when performing tasks such as deadlifts or pull-ups. Another method is the abdominal draw-in maneuver, which involves lying on your back with knees bent and feet flat on the floor. Place your fingers on the muscles just below your belly button, then contract those muscles by pulling them down and away from your fingers. Hold this position for 5 seconds, making sure to continue breathing.
Other treatments for back pain include drinking more water, eating more fruits and vegetables, and avoiding unhealthy habits such as smoking and excessive alcohol consumption.

Frequently asked questions
The transverse muscle, also known as the transverse abdominis, transversalis muscle, transversus abdominis muscle, or TVA, is a deep abdominal muscle that wraps around the abdomen. It is the deepest of the flat muscles, layered on top of the internal obliques.
The transverse muscle is a key stabiliser of the core, supporting the spine and keeping the body stable and balanced. It also helps to maintain internal abdominal pressure, which supports internal organs and aids in expulsive forces such as coughing, defecation, and urination.
The most well-known method of strengthening the TVA is the vacuum exercise. This involves sucking in the gut while performing tasks such as deadlifts or pull-ups. Another exercise is the abdominal draw-in manoeuvre, which involves lying on your back with knees bent and feet flat on the floor, placing your fingers on the muscles just below your belly button, and contracting those muscles by pulling them down and away from your fingers.
