A well-defined chest is the hallmark of a strong and aesthetically pleasing physique, but developing the lower chest can be particularly challenging. The lower chest, specifically the pectoralis major’s sternal head, often requires targeted exercises to achieve the coveted “shredded” look.
In this article, we’ll delve into the top three exercises that are essential for building a shredded lower chest. We’ll back up each exercise with scientific evidence and provide practical advice on how to incorporate these movements into your workout routine.
Understanding the Anatomy of the Lower Chest
Before diving into the exercises, it’s crucial to understand the anatomy of the chest muscles. The pectoralis major is the largest chest muscle and consists of two main parts: the clavicular head (upper chest) and the sternal head (lower chest). The sternal head originates from the sternum and attaches to the humerus, contributing to the bulk of the chest muscle. When fully developed, the sternal head creates the full, rounded appearance of the lower chest.
To effectively target the lower chest, exercises must involve movements that emphasize the sternal head. This typically involves pushing motions performed at a downward angle, which engage the lower fibres of the pectoralis major more than the upper fibres.
The Top 3 Exercises for a Shredded Lower Chest
1. Decline Bench Press
The decline bench press is one of the most effective exercises for targeting the lower chest. By positioning the body at a decline angle, this exercise shifts the focus of the press from the upper chest (clavicular head) to the lower chest (sternal head).
Why It Works: The Science Behind It
A study published in the Journal of Strength and Conditioning Research explored muscle activation during different variations of the bench press. The results showed that the decline bench press activated the lower pectoral muscles significantly more than the flat and incline bench presses, confirming its effectiveness for lower chest development (Glass et al., 1997).
The decline angle reduces the involvement of the anterior deltoids, allowing for greater isolation of the lower pectoral muscles. This makes it easier to build mass and definition in the lower chest region.
How to Perform the Decline Bench Press
- Set a bench to a decline of about 15-30 degrees.
- Lie on the bench with your feet securely hooked under the foot pads.
- Grasp the barbell with a grip slightly wider than shoulder-width.
- Lower the bar slowly to your lower chest, keeping your elbows at about a 45-degree angle to your body.
- Press the bar back up to the starting position, fully extending your arms.
Pro Tips
- Mind the Angle: A steeper decline (30 degrees) can increase lower chest activation, but it might also place more stress on your shoulders. Adjust the angle according to your comfort level.
- Control the Weight: Focus on controlling the descent to maximise muscle tension. The decline bench press is not about lifting the heaviest weight possible but rather about targeting the lower chest effectively.
2. Weighted Dips
Weighted dips are another potent exercise for the lower chest, especially when performed with a slight forward lean. This compound movement not only targets the lower chest but also works the triceps and shoulders, making it a great all-around upper body exercise.
Why It Works: The Science Behind It
A study in the European Journal of Applied Physiology found that dips, when performed with a forward torso lean, significantly increase activation of the sternal head of the pectoralis major (Lehman et al., 2005). This is because the forward lean shifts the emphasis from the triceps and shoulders to the chest, particularly the lower fibres.
Moreover, dips allow for a greater range of motion compared to bench presses, which can lead to more muscle activation and hypertrophy.
How to Perform Weighted Dips
- Position yourself on parallel bars with your hands shoulder-width apart.
- Start with your arms fully extended and your body vertical.
- Lean slightly forward, keeping your core engaged.
- Lower your body by bending your elbows until your shoulders are below your elbows.
- Push your body back up to the starting position, fully extending your arms.
Pro Tips
- Add Weight Gradually: Start with bodyweight dips and progressively add weight using a dip belt. This ensures you build strength safely.
- Focus on Form: Maintain a forward lean throughout the movement to keep the emphasis on your chest. Avoid swinging or using momentum.
3. Cable Crossovers (Low Pulley)
Cable crossovers from a low pulley position are a highly effective isolation exercise for the lower chest. This movement allows for continuous tension throughout the range of motion, which is ideal for muscle hypertrophy.
Why It Works: The Science Behind It
Research published in the Journal of Sports Science and Medicine highlighted that cable exercises, including cable crossovers, offer a unique advantage due to the consistent resistance provided by the cables. This constant tension ensures maximal muscle engagement throughout the exercise, particularly in the contracted position (Saeterbakken et al., 2011).
Cable crossovers from a low pulley specifically target the lower chest by mimicking the natural function of the sternal head, which is to bring the arms together and downward across the body.
How to Perform Low Pulley Cable Crossovers
- Set the pulleys to the lowest position on a cable machine.
- Stand in the centre with one handle in each hand, feet shoulder-width apart.
- Step forward slightly, keeping your torso upright and your elbows slightly bent.
- Pull the handles upward and inward in a scooping motion until your hands meet at chest level.
- Slowly return to the starting position, maintaining control.
Pro Tips
- Vary the Angle: While the low pulley is excellent for targeting the lower chest, you can adjust the pulley height slightly to experiment with different angles of tension.
- Squeeze at the Top: Focus on squeezing your chest at the top of the movement for maximum muscle contraction.
Incorporating These Exercises into Your Routine
To maximise the benefits of these exercises, it’s important to incorporate them into a well-structured workout routine. Here’s a sample chest workout focusing on the lower chest:
Sample Lower Chest Workout:
- Decline Bench Press: 4 sets of 8-12 reps
- Weighted Dips: 4 sets of 8-10 reps
- Low Pulley Cable Crossovers: 3 sets of 12-15 reps
- Flat Bench Press (optional): 3 sets of 8-12 reps (to ensure overall chest development)
Rest and Recovery
Rest is just as important as the workout itself. Allow at least 48 hours between chest workouts to give your muscles time to recover and grow. During this time, focus on nutrition, particularly protein intake, to support muscle repair and hypertrophy.
Progressive Overload
To continue seeing results, gradually increase the weight, reps, or intensity of your workouts. This principle of progressive overload is essential for muscle growth and strength gains.
Nutrition for a Shredded Lower Chest
Exercise alone isn’t enough to achieve a shredded lower chest. Nutrition plays a critical role in reducing body fat and revealing the muscle definition you’ve worked so hard to build.
Protein Intake
Protein is essential for muscle repair and growth. Aim for at least 1.6 to 2.2 grams of protein per kilogram of body weight daily, as recommended by the International Society of Sports Nutrition (Jäger et al., 2017).
Caloric Deficit
To reveal a shredded lower chest, you need to reduce body fat. This requires being in a caloric deficit, meaning you consume fewer calories than you burn. Focus on whole foods, lean proteins, and complex carbohydrates to maintain energy levels while cutting calories.
Hydration
Staying hydrated is crucial for overall health and optimal muscle function. Dehydration can impair performance and recovery, so aim for at least 3 litres of water per day.
Conclusion
Building a shredded lower chest requires targeted exercises that specifically engage the sternal head of the pectoralis major. The decline bench press, weighted dips, and low pulley cable crossovers are three of the most effective exercises for this purpose. By incorporating these movements into your workout routine and combining them with proper nutrition and progressive overload, you can develop a well-defined, powerful lower chest.
