Building a well-developed upper chest requires precise exercise selection, progressive overload, and a solid understanding of muscle mechanics. The upper chest is primarily composed of the clavicular head of the pectoralis major, which is activated most when performing pressing and fly movements at an incline.
If you want to increase muscle thickness and definition in this region, these five scientifically supported exercises will help you achieve your goals.
1. Incline Barbell Bench Press
The incline barbell bench press is one of the most effective exercises for targeting the upper portion of the pectoralis major. Research indicates that an incline angle of approximately 30 to 45 degrees maximises upper chest activation while minimising excessive front deltoid engagement (Lauver et al., 2016). The barbell variation allows for heavy loading, making it ideal for progressive overload.
How to Perform:
- Set the bench to a 30- to 45-degree incline.
- Grip the barbell slightly wider than shoulder-width.
- Lower the bar to the upper chest with control.
- Press the bar back up explosively.
- Maintain a steady and controlled movement throughout.
Benefits:
- Targets the upper chest more effectively than the flat bench press.
- Allows for heavier loading compared to dumbbells.
- Engages triceps and shoulders as secondary muscles.
2. Incline Dumbbell Press
Dumbbells provide a greater range of motion and unilateral training benefits, making the incline dumbbell press an excellent complement to the barbell variation. A study by Trebs et al. (2010) found that dumbbell presses elicited greater pectoral muscle activation compared to barbell presses due to increased stabilisation requirements.
How to Perform:
- Adjust the bench to a 30- to 45-degree incline.
- Hold a dumbbell in each hand, palms facing forward.
- Lower the dumbbells to chest level while keeping elbows at approximately a 45-degree angle.
- Press the weights back up, focusing on squeezing the chest.
- Avoid locking out your elbows at the top to keep tension on the muscles.
Benefits:
- Greater range of motion compared to barbell pressing.
- Helps address muscle imbalances between arms.
- Reduces the risk of barbell-related joint stress.
3. Low to High Cable Fly
Cable flyes allow for constant tension on the muscles throughout the movement, which can lead to better hypertrophy outcomes. Research has shown that cables provide a more consistent resistance curve compared to free weights, leading to greater muscle fibre recruitment (Saeterbakken & Fimland, 2013).
How to Perform:
- Set the cable pulleys to the lowest position.
- Hold a handle in each hand and step forward slightly.
- With a slight bend in the elbows, bring your hands up and together, squeezing the chest.
- Slowly return to the starting position.
- Focus on a controlled tempo to maximise time under tension.
Benefits:
- Provides constant tension throughout the movement.
- Excellent for upper chest isolation.
- Minimises triceps and shoulder involvement compared to pressing movements.
4. Reverse-Grip Bench Press
A lesser-known but highly effective exercise, the reverse-grip bench press has been shown to activate the upper chest significantly more than a traditional flat bench press. Studies suggest that the reverse grip increases the involvement of the clavicular head of the pectoralis major by up to 30% compared to a standard grip (Barnett, Kippers & Turner, 1995).
How to Perform:
- Lie on a flat bench and grip the bar with an underhand grip (palms facing you).
- Keep your hands slightly wider than shoulder-width apart.
- Lower the bar to your lower chest while keeping elbows tucked.
- Press the bar back up explosively.
- Ensure a spotter is present if lifting heavy.
Benefits:
- Places greater emphasis on the upper chest.
- Engages the biceps as a secondary stabiliser.
- Reduces stress on the shoulder joints compared to regular pressing.
5. Landmine Chest Press
The landmine chest press is an underutilised movement that allows for a more natural pressing motion, reducing shoulder strain while effectively targeting the upper chest. A study by Youdas et al. (2010) found that landmine presses engage the upper pectoral fibres to a high degree while also improving core stability.
How to Perform:
- Secure a barbell in a landmine attachment or place it in a corner.
- Hold the end of the barbell with both hands at chest level.
- Press the barbell up and slightly forward.
- Slowly lower it back down under control.
- Maintain a tight core to avoid excessive movement.
Benefits:
- Encourages a natural pressing motion that is easier on the shoulders.
- Engages the upper chest while incorporating core activation.
- A great alternative for those with shoulder mobility issues.
