The upper chest, primarily composed of the clavicular head of the pectoralis major, plays a crucial role in achieving a well-defined and proportionate chest. Research has shown that targeted exercise selection significantly impacts muscle hypertrophy (Schoenfeld, 2010).
Due to the fibres’ orientation, the clavicular head is best activated through movements with an upward angle, such as incline presses and fly variations (Saeterbakken et al., 2017).
Developing the upper chest not only enhances aesthetics but also improves pressing strength and shoulder stability, reducing injury risk.
The 3 Best Upper Chest Exercises
1. Incline Barbell Press
The incline barbell press is one of the most effective exercises for building the upper chest. A study by Trebs et al. (2010) demonstrated that an incline angle of 30–45 degrees maximises clavicular pectoralis major activation while minimising anterior deltoid dominance. Performing this exercise with a controlled eccentric phase and explosive concentric movement enhances mechanical tension, a key driver of muscle growth (Schoenfeld, 2016).
How to Perform:
- Set a bench to an incline between 30–45 degrees.
- Grip the bar slightly wider than shoulder-width.
- Lower the bar to the upper chest in a controlled manner.
- Press the bar back up explosively while maintaining tension.
- Perform 3–4 sets of 6–12 reps for hypertrophy.
Science-Backed Tips:
- Grip Width: A wider grip slightly increases upper chest activation by reducing elbow tuck (Lehman, 2005).
- Tempo Training: A slower eccentric phase (~3 seconds) enhances muscle damage and growth (Schoenfeld et al., 2015).
- Progressive Overload: Increasing weight or reps over time ensures continued hypertrophy.
2. Incline Dumbbell Fly
The incline dumbbell fly is a crucial movement for developing a well-rounded upper chest by focusing on stretch-mediated hypertrophy. A study by Schoenfeld et al. (2014) found that exercises with an extended range of motion and deep muscle stretch elicit greater hypertrophic responses compared to partial range movements.
How to Perform:
- Set a bench at an incline of 30–45 degrees.
- Hold dumbbells with a slight bend in the elbows.
- Lower the dumbbells in a controlled arc until a deep stretch is felt.
- Squeeze the chest and bring the dumbbells back to the starting position.
- Perform 3–4 sets of 10–15 reps.
Science-Backed Tips:
- Mind-Muscle Connection: Actively squeezing the chest at peak contraction improves neuromuscular activation (Calatayud et al., 2017).
- Mechanical Drop Sets: After reaching failure, reduce weight and continue to push past fatigue, enhancing hypertrophic response (Goto et al., 2003).
- Angle Optimisation: Avoid inclines above 45 degrees, which shift more tension to the anterior delts.
3. Low-to-High Cable Fly
Cable movements maintain continuous tension on the muscle, a key factor for hypertrophy. Research by Pinto et al. (2013) suggests that cable-based resistance training elicits similar or even greater activation levels compared to free weights in certain exercises due to constant mechanical tension.
How to Perform:
- Set the cables to the lowest position.
- With a slight forward lean, pull the handles upwards in a controlled manner.
- Squeeze the upper chest at the top of the movement.
- Slowly return to the starting position.
- Perform 3–4 sets of 12–15 reps.
Science-Backed Tips:
- Eccentric Focus: Slowing the lowering phase increases time under tension, promoting muscle growth (McMahon et al., 2014).
- Peak Contraction: Holding the top position for 1–2 seconds enhances metabolic stress, a key hypertrophy mechanism (Schoenfeld, 2010).
- Variation: Incorporate unilateral cable flys to correct muscular imbalances.
Key Training Considerations for Maximum Growth
Progressive Overload
Progressive overload is essential for continued muscle development. This principle involves gradually increasing resistance, volume, or intensity over time. Studies indicate that even small increments in load significantly impact hypertrophy (Kraemer et al., 2004).
Training Frequency and Volume
Research by Schoenfeld et al. (2019) highlights that training a muscle group at least twice per week results in superior hypertrophy compared to once per week. Aim for 12–20 sets of upper chest work per week, distributed across multiple sessions.
Nutrition and Recovery
Adequate protein intake and recovery play pivotal roles in muscle growth. Protein synthesis is maximised at an intake of 1.6–2.2 g/kg of body weight per day (Morton et al., 2018). Additionally, optimising sleep quality and managing stress enhance recovery and performance (Halson, 2014).
Conclusion
Building a chiselled upper chest requires strategic exercise selection, progressive overload, and attention to training variables. The incline barbell press, incline dumbbell fly, and low-to-high cable fly are the three most effective movements for targeting the upper chest. By applying scientific principles and ensuring adequate recovery, you can achieve a well-defined and aesthetic upper chest.
