The serratus anterior muscle plays a pivotal role in stabilising the shoulder blade and aiding shoulder movement, making it essential for functional upper-body strength. Well-developed serratus muscles also contribute to a defined and impressive six-pack appearance.
Often overlooked in traditional ab workouts, training the serratus can give you a more complete, shredded core. This article delves into seven exercises that target the serratus anterior and how they can help build a sculpted six-pack while improving shoulder function.
The Importance of the Serratus Anterior
The serratus anterior muscle originates from the surface of the first to the eighth ribs and inserts into the scapula. Its primary function is to protract and stabilise the scapula against the thoracic wall. This muscle is crucial for overhead movements like lifting and pushing, and plays a role in shoulder health and posture. It is often referred to as the “boxer’s muscle” due to its engagement during punching movements. Strengthening the serratus anterior improves shoulder stability and reduces the risk of injury, especially in athletes and weightlifters.
Several studies highlight the role of the serratus anterior in shoulder function. A study by Kibler et al. (2006) showed that weakness in the serratus anterior can lead to scapular winging, which may cause shoulder pain and dysfunction in overhead movements (Kibler et al., 2006). Another study by Moseley et al. (1992) confirmed that exercises activating the serratus anterior improve shoulder mechanics and reduce the risk of impingement injuries (Moseley et al., 1992).
1. Serratus Punch
How It Works
The serratus punch is a simple yet effective exercise to directly target the serratus anterior. This movement mimics the protraction of the scapula, which is essential for developing the serratus.
How to Perform:
- Stand or lie flat on your back with a dumbbell in one hand.
- Extend your arm straight upwards, keeping your shoulder blade flat on the bench or floor.
- Without bending your elbow, push the dumbbell higher by protracting your scapula (pushing it forward).
- Slowly lower the dumbbell back to the starting position.
Why It’s Effective:
This exercise isolates the serratus anterior and trains it to stabilise the scapula. A study by Escamilla et al. (2009) demonstrated that protraction exercises like the serratus punch highly activate the serratus anterior, leading to greater strength and hypertrophy (Escamilla et al., 2009).
2. Push-Up Plus
How It Works
The push-up plus is an advanced version of the traditional push-up, where the scapular protraction at the top of the movement increases serratus anterior engagement.
How to Perform:
- Begin in a plank position with your hands placed slightly wider than shoulder-width apart.
- Lower your body into a push-up, then push back up to the top position.
- Once you reach the top, perform an additional scapular protraction by pushing your body slightly further away from the ground, rounding your upper back.
- Hold the protracted position for a moment, then return to the starting position.
Why It’s Effective:
Adding the protraction at the top of a push-up shifts the emphasis to the serratus anterior, while still engaging the chest and triceps. According to Decker et al. (1999), this “plus” motion increases activation of the serratus anterior by 32%, making it one of the most effective exercises for serratus development (Decker et al., 1999).
3. Cable Serratus Crunch
How It Works
This exercise combines spinal flexion with scapular protraction to engage both the abs and the serratus anterior.
How to Perform:
- Attach a rope handle to a high pulley on a cable machine.
- Kneel down, holding the rope with both hands.
- Engage your core and perform a crunching motion, pulling the rope downwards while simultaneously protracting your scapula.
- Return to the starting position in a controlled manner.
Why It’s Effective:
By combining core engagement with scapular protraction, the cable serratus crunch allows for a functional movement that trains the serratus anterior along with the rest of your core. Studies show that movements involving both dynamic core and scapular control have a significant impact on serratus strength and overall shoulder stability (Ludewig & Cook, 2000).
4. Dumbbell Pullover
How It Works
The dumbbell pullover primarily targets the lats, but when done correctly, it also recruits the serratus anterior through the scapular protraction involved in the movement.
How to Perform:
- Lie flat on a bench with your upper back supported and hold a dumbbell with both hands above your chest.
- Keeping your arms straight but elbows slightly bent, lower the dumbbell behind your head in a controlled motion.
- Reverse the motion by pulling the dumbbell back over your chest, focusing on protracting your scapula at the top of the movement.
Why It’s Effective:
The dumbbell pullover enhances shoulder mobility and scapular strength. According to a study by Contreras et al. (2011), the dumbbell pullover showed significant activation of both the latissimus dorsi and the serratus anterior when performed with proper form (Contreras et al., 2011). This dual activation makes it an efficient exercise for upper-body development.
5. Scapular Wall Slides
How It Works
Scapular wall slides are excellent for developing serratus anterior strength and scapular mobility. They also improve posture by activating the muscles responsible for scapular control.
How to Perform:
- Stand with your back against a wall and feet shoulder-width apart.
- Raise your arms up against the wall with your elbows bent at a 90-degree angle.
- Slowly slide your arms up the wall while keeping your back and elbows in contact with it.
- Focus on protracting your scapula at the top of the movement, then lower your arms back down.
Why It’s Effective:
This movement improves scapular mobility and promotes the activation of the serratus anterior while correcting postural imbalances. A study by McClure et al. (2004) found that scapular wall slides are effective for enhancing shoulder mechanics and reducing the risk of injury in athletes (McClure et al., 2004).
6. Bear Crawl
How It Works
The bear crawl is a full-body exercise that engages the core, shoulders, and serratus anterior. This exercise mimics natural movement patterns and stabilises the shoulder through scapular protraction.
How to Perform:
- Begin on all fours with your hands and feet on the ground, keeping your knees just off the floor.
- Move your opposite arm and leg forward simultaneously, alternating sides as you crawl forward.
- Keep your core tight and focus on protracting your scapula with each step.
Why It’s Effective:
The bear crawl places a high demand on scapular stabilisation, challenging the serratus anterior in a dynamic and functional way. Research shows that closed-chain exercises like the bear crawl promote higher serratus anterior activation compared to isolated movements (Saeterbakken et al., 2015). This makes it a great exercise for building functional strength in the serratus while improving overall shoulder stability.
7. Landmine Press
How It Works
The landmine press targets the shoulders and chest, but when executed with proper technique, it can also recruit the serratus anterior by engaging scapular protraction at the top of the movement.
How to Perform:
- Place one end of a barbell in a landmine attachment or in a corner.
- Stand with your feet shoulder-width apart and grasp the other end of the barbell with one hand.
- Press the barbell upwards at a slight angle while allowing your shoulder blade to protract as you reach the top of the press.
- Slowly lower the barbell back down, maintaining control.
Why It’s Effective:
The landmine press incorporates multi-planar movement, which trains the serratus anterior in a functional range of motion. According to Andersen et al. (2014), exercises that combine pressing and protraction movements are highly effective for serratus activation, contributing to better scapular stability (Andersen et al., 2014).
Conclusion
The serratus anterior plays a crucial role in both aesthetics and function. Neglecting this muscle can lead to shoulder instability, injury, and an incomplete core development. Incorporating exercises like the serratus punch, push-up plus, and landmine press into your routine can help develop shredded serratus muscles while enhancing shoulder mechanics. Backed by scientific research, these exercises are not only essential for athletes and bodybuilders but also for anyone looking to improve their posture and upper-body strength. Ensure that you prioritise proper form and gradually increase intensity to get the most out of your serratus workouts.
