The rib cage is a vital part of the human body, protecting the lungs and other vital organs. It is composed of 12 pairs of ribs, with each rib connected to the one below it by a set of intercostal muscles. These intercostal muscles are essential for movement and breathing, assisting in the expansion and contraction of the lungs. The external intercostal muscles lift and spread the ribs during inhalation, while the internal intercostal muscles depress and pull the ribs closer together during exhalation. Strengthening these muscles can improve respiratory fitness and increase lung capacity. Additionally, exercises such as push-ups, bench presses, and dumbbell pullovers can help build and strengthen the muscles surrounding the rib cage, including the serratus anterior muscles. In sports like boxing, protecting the ribs is crucial, and proper footwork, maintaining a balanced stance, and using strategic movements are essential for defence.

What You'll Learn
Intercostal muscles
The intercostal muscles are a group of 22 pairs of small muscles found between the ribs. They are divided into three layers: the external intercostals, the internal intercostals, and the innermost intercostals.
The external intercostal muscles, or intercostalis externus, aid in quiet and forced inhalation. They originate on ribs 1–11 and have their insertions on ribs 2–12. The contraction of these muscles elevates the ribs and bends them open, thus expanding the chest wall and the transverse dimensions of the thoracic cavity.
The internal intercostal muscles, or intercostalis internus, aid in forced expiration. They originate on ribs 2–12 and have their insertions on ribs 1–11. Their contraction depresses the ribs and bends them inward, decreasing the transverse dimensions of the thoracic cavity.
The innermost intercostal muscles, or intercostalis intimus, are deep layers of the internal intercostal muscles, separated from them by a neurovascular bundle. Their fibres are directed downwards, forwards, and laterally, similar to the internal intercostal muscles.
All three groups of intercostal muscles support the rib cage and are accessory respiratory muscles that participate in the process of forced breathing. They help to solidify the thoracic region and protect the lungs.
Intercostal muscle strains can occur due to weakened muscles, overexertion, direct trauma, or repetitive torso twisting. Symptoms of a strain include pain, muscle tension and stiffness, and inflammation.

Serratus anterior muscles
The serratus anterior muscle is a fan-shaped muscle that originates on the superolateral surfaces of the first to eighth or ninth ribs at the lateral wall of the thorax. The serratus anterior muscle is also known as the "boxer's muscle" or the "big swing muscle" because it is responsible for the protraction of the scapula, or the pulling of the scapula forward and around the rib cage that occurs when someone throws a punch. The main part of the serratus anterior lies deep to the scapula and the pectoral muscles and is easily palpated between the pectoralis major and latissimus dorsi muscles. The serratus anterior is innervated by the long thoracic nerve, a branch of the brachial plexus. The long thoracic nerve travels inferiorly on the surface of the serratus anterior muscle.
The serratus anterior is divided into three parts according to the points of insertion: the serratus anterior superior is inserted near the superior angle; the serratus anterior intermediate is inserted along the medial border; and the serratus anterior inferior is inserted near the inferior angle. All three parts of the serratus anterior pull the scapula forward around the thorax, which is essential for the anteversion of the arm. When the inferior and superior parts act together, they keep the scapula pressed against the thorax together with the rhomboids. The serratus anterior acts in concert with the upper and lower fibres of the trapezius muscle to sustain upward rotation of the scapula, which allows for overhead lifting.
The serratus anterior has a variety of functions. Firstly, it is responsible for the active stabilisation of the scapula within the shoulder. Secondly, when the shoulder girdle is fixed, all three parts of the serratus anterior work together to lift the ribs, assisting with respiration. Thirdly, in cursorial mammals such as the horse, the serratus anterior supports the scapula against the reaction forces of the free limb and exerts high bending forces on the ribs.
The serratus anterior muscle can be targeted through exercises such as push-ups, bench presses, and dumbbell pullovers.

Guarding ribs in boxing
The ribs are protected by the intercostal muscles, which are a group of 22 pairs of small muscles found between the ribs. These muscles are vital for the movement of the chest during breathing and they also help to protect the lungs. While the rib cage and its muscles protect the lungs, a well-aimed punch to the ribs during a boxing match can cause injury or even result in a knockout.
To guard your ribs in boxing, it is important to stay out of your opponent's range and maintain a good defensive position. Footwork and continuous movement are key to avoiding punches, as they make you a more difficult target to strike. Keeping your knees slightly bent and practising quick movements in different directions can help improve your balance and make you more agile.
Cardiovascular conditioning is also important, as it allows you to maintain a higher rate of motion for longer, making it harder for your opponent to keep up and hit you in the ribs. Observing your opponent's tendencies during the fight can also give you an advantage, as you can identify their commonly used tactics, strengths and weaknesses. Knowing which hand they use for power punches, for example, can help you circle away from a blow to the ribs.
While it is not possible to cover your ribs entirely with muscles, some exercises can help to strengthen the muscles in this area. Boxing training often focuses on building muscle in the abdomen and neck, which can help distribute the impact of blows away from vulnerable areas. Exercises such as sit-ups, bicep curls, bench presses, and power lifts can help to strengthen the intercostal muscles and improve respiratory fitness. Twisting ab exercises and exercises that involve the serratus muscles, such as pull-ups, can also help to improve your defence against body shots.

Breathing exercises
The intercostal muscles are a group of 22 pairs of small muscles found between the ribs. These muscles are essential for the movement of the chest during breathing and provide protection to the lungs. The external intercostal muscles lift and spread the ribs during inhalation, while the internal intercostal muscles pull the ribs closer together during exhalation.
Basic Breathing Exercise
Sit comfortably with your spine straight and chest lifted. Inhale slowly and deeply through your nose, ensuring your upper chest remains still and relaxed. Then, exhale slowly through pursed lips, as if you are blowing out candles. Focus on pulling your abdomen towards your spine during exhalation. Repeat this exercise five times.
Bellow's Breath
Sit in a comfortable position and inhale naturally through your nose. On the exhale, snap your stomach muscles in, forcing the air out. Repeat this breathing pattern for 30 seconds, gradually increasing the pace.
Intercostal Stretching Breath
Stand up and stretch your arms overhead. Inhale deeply, and on the exhale, stretch your arms to the right, feeling the stretch on the left side of your body. Inhale and return to the centre, then exhale and stretch your arms to the left, feeling the stretch on the right side.
Overhead Chest Stretch
Sit in a chair or lean back on a bed, gently squeezing your shoulder blades back and down. Hold your hands together and slowly raise them overhead while taking a deep breath in. Slowly lower your hands while breathing out and relax for a moment. Repeat this exercise five times.
Quick Sniffles
Sit in a chair or lean back on a bed. Take a deep breath through your nose, then quickly sniff in through your nose at least three times without exhaling.
Shoulder Rolls
Sit or lean back with your arms relaxed at your sides. In a circular motion, bring your shoulders forward, up, backward, and down. This is a gentle stretch for your chest and shoulders.
Yoga Arm Balance
This exercise is derived from a yoga pose called Tolasana. Begin on your knees with an ab roller in front of you. Bend down and grasp either side of the roller, keeping your core and hips contracted. Roll out as far as you can without bending your hips or back, using a slow and controlled motion. Maintain slightly bent elbows. Use your core strength to slowly roll back to the starting position.
Additionally, exercises such as push-ups, bench presses, and dumbbell pullovers can also help work the muscles around the rib cage.
Remember, it is always advisable to consult a healthcare professional before starting any new exercise routine.

Weight training
The intercostal muscles are a group of 22 pairs of small muscles found between the ribs. These muscles help to protect the lungs and facilitate breathing. Strengthening these muscles will increase lung capacity and improve respiratory fitness.
- Push-ups: Adding a bonus movement to a basic push-up can help target the serratus anterior and rib muscles. Get into a push-up position and lower down, bending your elbows back while keeping your core locked.
- Bench presses: This compound exercise works multiple muscle groups, including the chest, triceps, and shoulders, and also targets the intercostal muscles.
- Dumbbell pullovers: This exercise works the muscles along your rib cage. Lie on a bench with a dumbbell in each hand, extended straight above your chest. Keep your elbows slightly bent and slowly lower the dumbbell back and beyond your head until your upper arms are in line with your torso. Slowly raise the dumbbell back up over your chest.
- Ab roller: Using an ab roller or a barbell set up with round plates, focus on contracting your serratus and rib muscles as you roll out and in. Begin on your knees with the roller on the ground in front of you and grasp either side of the roller. Keep your core and hips contracted, and use a slow and controlled motion to roll out and back.
In addition to these weight training exercises, deep breathing exercises can also help strengthen the intercostal muscles and improve respiratory function. Sit comfortably with your spine straight and chest lifted. Inhale for two seconds, hold for two seconds, and then exhale for four seconds. As you improve, gradually increase the duration of each breath.
