Achieving a well-defined and strong upper chest is a common goal for many fitness enthusiasts, athletes, and bodybuilders alike. The upper portion of the chest, also known as the clavicular head of the pectoralis major, plays a crucial role in creating that coveted, full-chested look. A well-developed upper chest not only contributes to aesthetics but also enhances overall upper body strength and functional performance.
This article explores the three best exercises for targeting and developing the upper chest, backed by scientific research and expert recommendations. These exercises have been chosen based on their effectiveness in activating the upper chest fibres, ease of execution, and their adaptability to different training routines.
Understanding the Upper Chest: Anatomy and Function
Before diving into the exercises, it’s essential to understand the anatomy and function of the upper chest muscles. The pectoralis major is a large, fan-shaped muscle that covers much of the chest. It is divided into two primary sections: the clavicular head (upper chest) and the sternal head (middle and lower chest).
The clavicular head originates from the clavicle (collarbone) and inserts into the humerus (upper arm bone). This section of the pectoralis major is responsible for shoulder flexion, horizontal adduction, and internal rotation of the humerus. In simpler terms, the upper chest is activated when you lift your arms forward, push something away from your body, or bring your arms together in front of you.
Due to the muscle’s orientation, exercises that involve an incline position are particularly effective at targeting the upper chest. Let’s explore the top three exercises that have been proven to yield the best results for upper chest development.
1. Incline Barbell Bench Press
Why It Works
The incline barbell bench press is widely regarded as the king of upper chest exercises. When performed at the correct angle, it primarily targets the clavicular head of the pectoralis major. Research has shown that the incline bench press activates the upper chest fibres more effectively than the flat bench press, making it a must-have in any upper chest workout routine.
A study published in the “Journal of Strength and Conditioning Research” compared muscle activation during different bench press variations. The researchers found that the incline bench press resulted in significantly greater activation of the upper chest compared to the flat and decline bench presses (Barnett et al., 1995). This makes the incline barbell bench press an essential exercise for anyone looking to build a stronger and more defined upper chest.
How to Perform the Incline Barbell Bench Press
- Set the Bench Angle: Adjust the bench to an incline of about 30 to 45 degrees. A steeper incline will shift the emphasis towards the shoulders, so it’s essential to find a moderate angle that maximises upper chest engagement.
- Grip the Barbell: Lie on the bench with your feet flat on the floor. Grip the barbell slightly wider than shoulder-width apart. Ensure that your wrists are aligned with your elbows to maintain proper form.
- Lower the Barbell: Slowly lower the barbell to your upper chest, keeping your elbows at a 45-degree angle relative to your torso. This position reduces stress on the shoulders and maximises chest activation.
- Press the Barbell Up: Drive the barbell upward in a controlled manner, fully extending your arms without locking your elbows. Focus on squeezing your chest at the top of the movement.
- Repeat: Perform 3 to 4 sets of 8 to 12 repetitions, adjusting the weight as needed to maintain proper form.
Key Tips
- Avoid lowering the bar too quickly, as this can lead to improper form and increase the risk of injury.
- Keep your shoulder blades retracted throughout the movement to stabilise your upper body.
- Engage your core to maintain a stable and strong base during the lift.
2. Dumbbell Incline Press
Why It Works
The dumbbell incline press is another highly effective exercise for developing the upper chest. Like the barbell version, it targets the clavicular head, but it also offers several unique advantages. Using dumbbells allows for a greater range of motion, which can lead to improved muscle activation and hypertrophy. Additionally, dumbbells require more stabilisation, engaging the smaller supporting muscles in the shoulders and chest.
A study conducted by Saeterbakken et al. (2011) in the “Journal of Sports Sciences” found that the dumbbell bench press elicited higher muscle activation in the pectoralis major compared to the barbell bench press. This increased activation can be particularly beneficial for targeting the upper chest when performing the exercise on an incline.
How to Perform the Dumbbell Incline Press
- Set the Bench Angle: As with the barbell version, set the bench to an incline of 30 to 45 degrees.
- Grip the Dumbbells: Sit on the bench with a dumbbell in each hand, resting them on your thighs. Use your legs to help lift the dumbbells as you lie back on the bench. Position the dumbbells with your palms facing forward and your wrists directly above your elbows.
- Lower the Dumbbells: Lower the dumbbells slowly and with control, bringing them down to your upper chest. Your elbows should remain at a 45-degree angle relative to your torso.
- Press the Dumbbells Up: Push the dumbbells back up to the starting position, fully extending your arms while avoiding locking your elbows. Focus on contracting your chest muscles at the top of the movement.
- Repeat: Perform 3 to 4 sets of 8 to 12 repetitions, adjusting the weight as necessary to maintain good form.
Key Tips
- Maintain a controlled tempo throughout the movement to maximise muscle tension.
- Avoid flaring your elbows too wide, as this can place unnecessary strain on your shoulder joints.
- Engage your core and keep your back flat against the bench to prevent arching.
3. Incline Cable Fly
Why It Works
The incline cable fly is an isolation exercise that specifically targets the upper chest by stretching and contracting the muscle fibres in a different plane of motion compared to pressing exercises. Cable machines provide constant tension throughout the movement, which can lead to more effective muscle engagement and growth.
Research published in the “Journal of Applied Biomechanics” highlighted that cable flys, when performed correctly, lead to higher levels of pectoral activation compared to free-weight flys (Welsch et al., 2005). The ability to adjust the angle of the cables also allows for a more customised approach to targeting the upper chest.
How to Perform the Incline Cable Fly
- Set the Cable Machine: Adjust the pulleys on the cable machine to the lowest setting and attach a single handle to each side. Set an incline bench in the centre of the machine.
- Grip the Handles: Sit on the bench with a handle in each hand, palms facing each other. Lie back on the bench and extend your arms above your chest with a slight bend in your elbows.
- Lower the Handles: With control, lower the handles in an arc motion, bringing them down and out to the sides. Your elbows should remain slightly bent throughout the movement to protect your joints.
- Bring the Handles Together: Squeeze your chest muscles as you bring the handles back up to the starting position, focusing on bringing your hands together above your upper chest.
- Repeat: Perform 3 to 4 sets of 10 to 15 repetitions, adjusting the weight as needed to ensure good form.
Key Tips
- Focus on the stretch at the bottom of the movement to fully engage the upper chest fibres.
- Keep the motion slow and controlled to maximise tension on the chest muscles.
- Avoid using too much weight, as this can compromise form and reduce the effectiveness of the exercise.
Conclusion: Building a Strong and Defined Upper Chest
Developing a strong and defined upper chest requires consistent effort, proper form, and the right exercise selection. The incline barbell bench press, dumbbell incline press, and incline cable fly are three of the most effective exercises for targeting the clavicular head of the pectoralis major. Incorporating these exercises into your routine can lead to significant improvements in upper chest strength and aesthetics.
It’s important to note that while these exercises are highly effective, they should be part of a well-rounded training programme that includes exercises for the entire chest, shoulders, and triceps. Additionally, proper nutrition, adequate rest, and progressive overload are crucial factors in achieving optimal muscle growth.
