The transversus abdominis (TVA) is a deep abdominal muscle that wraps around the abdomen like a natural corset. It is the deepest layer of abdominal muscle and is responsible for stabilising the spine and protecting the internal organs. Training the TVA can help to reduce back pain, improve posture and make daily activities easier. However, it is often overlooked in ab workouts as it sits under the other ab muscles and is therefore not visible. To train the TVA, it is important to first learn how to relax and contract the pelvic floor muscles and then use imagery to connect to the TVA. Once this connection is established, there are various exercises that can be performed to strengthen the TVA, such as planks, hip bridges and breathing exercises.

What You'll Learn

TVA activation exercises
The transversus abdominis (TVA) is a deep abdominal muscle that sits horizontally around your abdomen, often referred to as the "'corset' muscle". It is the deepest layer of abdominal muscle and is crucial for a strong core and a defined waistline. A weak TVA can lead to lower back pain, pelvic floor dysfunction, and tight hips.
Pelvic Floor Muscles
The TVA works in conjunction with the pelvic floor muscles to stabilize the pelvis and provide pelvic organ support. To relax and contract the pelvic floor muscles, gently tighten the anal sphincter and then draw the anus up towards the pubic bone.
Diaphragmatic Breathing
Deep breathing techniques are beneficial for the TVA. Inhale through your nose to expand your belly from the pubic bone to the rib cage. Exhale through your mouth while squeezing and contracting your abdominal muscles.
Core Bracing
The core brace technique is a quick way to activate the TVA. Breathe deeply, and as you exhale, tighten your belly area as if you're preparing for a punch to the stomach or about to lift something heavy.
Planks
Planks are a great full-body workout that targets the TVA. Get into a push-up position, resting your weight on your forearms with your arms at a 90-degree angle. Keep your back straight and hold your body weight on your forearms for as long as you can.
Hip Bridge
Lie on your back with your knees bent, feet flat, and arms at your sides. Contract your abdominals to lift your hips off the floor and pull them towards your rib cage. Slowly lower your body back down, controlling the movement with your abdominals.
"C" Curve
Sit tall on the ground with your knees bent and your arms on your legs. "Scoop" out your belly, arching backward, and drawing your stomach up towards your spine. Roll back into the seated position and repeat.
Remember, it's important to train and activate the TVA before focusing on strengthening it. Start with a few repetitions and gradually increase as you become more comfortable with the exercises.

TVA bracing and hollowing techniques
The transverse abdominis (TVA) is a deep abdominal muscle that wraps around the abdomen, creating a "cinching" effect similar to a natural "corset". It is the deepest layer of abdominal muscle and the only one where the fibres run side to side.
The TVA plays a crucial role in stabilising the spine and improving posture. It also helps to maintain normal abdominal wall tension and increase intra-abdominal pressure, which aids the internal organs and viscera. A weak TVA can lead to lower back pain and pelvic floor dysfunction.
Bracing refers to an isometric contraction of the TVA, where you contract the abdominal muscles and hold them tight without moving. This creates a stiffening effect that protects the spine. To brace, imagine you are about to be punched in the stomach or are preparing to lift a heavy object. The goal is to tighten the muscles without sucking in or expanding your abdomen. Breathe in and out as you hold.
Hollowing, on the other hand, involves sucking in and compressing the abdomen. Contract your abdomen and pull your belly button back towards your spine to make your abdomen as small as possible. Then, hold this compressed position for 6 to 10 seconds before releasing and repeating.
Both bracing and hollowing exercises have been found to have positive effects on spinal stability and abdominal muscles. However, one study found bracing to be more effective in stabilising the lumbar spine than hollowing.
It is important to note that you should train before you strengthen the TVA. This means learning to relax and contract the pelvic floor muscles and using imagery to connect to the TVA.

TVA and the pelvic floor
The transversus abdominis (TVA) is a deep abdominal muscle that wraps around the abdomen, much like a corset. It is the deepest layer of abdominal muscle and the only one in which the muscle fibres run side to side.
The TVA plays a crucial role in everyday movements, protecting and stabilising the spine and supporting the internal organs. It also helps to maintain normal abdominal wall tension and increase intra-abdominal pressure, which aids expulsive forces such as forced expiration, late-stage childbirth, urination, and defecation.
The TVA, diaphragm, multifidus, and pelvic floor muscles work together to create and maintain intra-abdominal pressure, with the TVA and pelvic floor muscles working in tandem to stabilise the pelvis. When the TVA and pelvic floor are functioning optimally, they help to transfer force more efficiently through the muscles, rather than through the back and hip joints.
To train the TVA and pelvic floor to work together, it is important to first learn how to relax and contract the pelvic floor muscles with your breath. This can be done by imagining a line that connects the inside of your two pelvic bones (front of hips) and gently tightening the anal sphincter, drawing the anus up towards the pubic bone. Once you have learned to relax and contract the pelvic floor, you can use imagery to connect to the TVA, such as by imagining a line connecting the inside of your lower ribs at the front and visualising a deep, gentle force hugging your ribs together.
Exercises such as cat-cow pose and pelvic rocking can also help to strengthen the TVA and pelvic floor. As you exhale into cat pose, draw your navel in towards your spine to engage the TVA, and then perform a kegel at the end of the exhale to engage the pelvic floor.

TVA and the diaphragm
The transverse abdominal muscle (TVA), also known as the transversus abdominis, transversalis muscle, and transversus abdominis muscle, is a muscle layer of the front and side abdominal wall. It is the deepest abdominal muscle, wrapping around the abdomen between the lower half of the ribs and the top of the pelvis.
The TVA functions to stabilise the lumbopelvic region (lower back and hips) and the lower part of the upper back (lower thoracic spine) during movements that involve the arms and legs. It also helps to maintain abdominal wall tension and increase intra-abdominal pressure, which supports internal organs and aids in forced expiration, urination, and defecation.
To train the TVA, it is important to first learn how to relax and contract the pelvic floor muscles with your breath. This is because the TVA must work in synergy with the diaphragm and pelvic floor muscles to stabilise the pelvis and spine. The diaphragm is a dome-shaped muscle located just above the stomach and below the lungs. It plays a crucial role in breathing by contracting and relaxing to allow air to move in and out of the lungs.
Once you have learned to relax and contract the pelvic floor muscles, you can use imagery to connect to the TVA. Imagine a line connecting the inside of your two pelvic bones (front of the hips) and gently tighten the anal sphincter, drawing the anus up towards the pubic bone. This will help activate the TVA and improve its function.
Breathing exercises can also be beneficial for training the TVA. The vacuum exercise is the most well-known method, which involves breathing in and expanding the chest instead of the stomach or belly. This can make breathing harder, but it is a good way to train the TVA. It is important to note that you should still focus on diaphragmatic breathing by ensuring you are breathing through your belly at rest and incorporating specific breathing exercises.

TVA and the transversus abdominis
The transversus abdominis (TVA) is a deep abdominal muscle that wraps around the abdomen like a natural "corset". It is the deepest layer of abdominal muscle, situated close to the spine and internal organs, and is responsible for creating a "cinching" effect.
The TVA plays a crucial role in stabilising the spine and protecting it from injury. It also helps to maintain normal abdominal wall tension and increase intra-abdominal pressure, which supports internal organs and aids expulsive forces such as forced expiration, late-stage childbirth, urination, and defecation.
A weak TVA can lead to lower back pain, pelvic floor dysfunction, and tight hips. Therefore, it is important to train and strengthen the TVA to improve core stability and reduce the risk of injury.
To activate the TVA, one can practice the "'bracing'" technique, which involves contracting the muscles of the abdomen and holding them tight without moving, as if preparing to receive a punch to the belly. Another technique is "hollowing", which involves sucking in and compressing the abdomen by pulling the belly button back towards the spine to make the abdomen as small as possible. This position is then held for 6 to 10 seconds.
Once the TVA can be activated, exercises such as planks, side planks, and hip bridges can be performed to strengthen the muscle. It is important to focus on engaging the TVA during these exercises to ensure the full benefit is received.
