10 Best Inner Chest Exercises To Build Mass

If you want to build a bigger and stronger chest, you should add inner chest exercise to your chest workout routine.

Why is inner chest workout so vital? The inner chest muscles are smaller than the upper and lower chest muscles, but they are still important for strength and a defined look. And if you want to achieve a truly balanced and proportionate chest, it’s important to train the inner chest along with the other chest muscles.

The greatest technique for strengthening your inner chest is to do exercises that encourage you to move your arms towards your chests’ midline.

What are the Inner Chest Muscles?

To effectively target the inner chest, it’s essential to have a basic understanding of the underlying anatomy. The chest muscles, or pectoral muscles, are divided into two main parts:

The pectoralis major itself comprises two heads: the upper head (or clavicular) and lower head (or sternal) portions.

The inner chest is the region of the chest that is located between the two pectoralis major muscles. It’s the most prominent muscle of the pecs. The sternal head, which is the lower chest, is the home of the inner chest.

So, to really hit the inner part of your pecs, you need to perform exercises where the arms come together (or even cross) the midline of the body.

How To Train Inner Chest

To structure an effective inner chest workout to increase mass and strength, the number of reps and sets will vary based on your fitness level, weekly workout frequency, and strength training goals.

For strength gains, do 4 to 6 sets of 1 to 6 reps each exercise with a weight that is at least 85% of your one-repetition maximum (1RM) The fewer reps you perform, the closer to 100% of your 1RM you should strive for.

If your goal is hypertrophy (muscle growth), perform three sets of each exercise, using loads that are 70 to 85% of your 1RM for 8 to 12 reps.

When training for endurance, it is usually recommended to use higher reps (15 to 20 repetitions) and moderate loads, with a weight that is at least 50 to 70% of your 1RM.

10 Best Inner Chest Exercises To Build Mass and Strength

Now let’s explore the best inner chest exercises for strengthening your chest and improving posture using various types of fitness equipment, as well as some bodyweight workouts that you can do at home.

Here is a list of 10 best exercises to strengthen the inner chest and help you achieve a strong, defined chest.

1. Dumbbell Inner Chest Exercises
2. Dumbbell Squeeze Press
3. Dumbbell fly
4. Dumbbell Pullover
5. Landmine Chest Press
6. Smith Machine Hex Press
7. Pec Deck Fly
8. Cable Crossover
9. Single Arm Chest Fly
10. Plate Squeeze Press

1. Narrow Grip Push-Ups

Narrow grip push-ups are the best bodyweight workout for building your entire upper body, including shoulders, chest, and triceps. Close grip push ups focus on building the inner part of your chest. It’s one of the best inner chest exercises you can do at home.

This is evidenced by a study which found that there is greater electromyography (EMG) activity in the triceps brachii and inner chest when doing close push-ups as compared to when executing regular push-ups.

Close grip push-ups can be challenging, so it’s important to start with a modified version (knee push ups) if needed.

How To Do

1. Begin in a plank position with your hands directly under your shoulders and your feet hip-width apart.
2. Move your hands closer together so that they are directly under your chest, with your fingers pointing forward.
3. Lower your body towards the ground, keeping your elbows close to your sides.
4. Pause at the bottom of the movement, then push back up to the starting position, focus on contracting your inner chest muscles.
5. Repeat for the desired number of reps.

Tips

• Exhale while you exert.
• Keep flexing the inner pecs as you lower down and then return

2. Dumbbell Squeeze Press

If you’re looking for a straightforward inner chest dumbbell exercise to add to your routine, dumbbells squeeze press is a great staple workout to get you started. It is one of the most effective dumbbell chest pressing exercises which target the inner chest.

During the squeeze press, the dumbbells are kept in contact with each other at all times, and you’re actively squeezing them inward (against each other) as hard as possible.

How To Do

1. Take the dumbbells in each of your hands, and lay down on the bench.
2. Place the dumbbells together side by side, and lift them up over your chest.
3. You’ll want to maintain a lot of tension in the inner chest.
4. Lower them down together, touch the chest, and then push the dumbbells back up.
5. Repeat for the desired number of repetitions.

Tips

• Breathe out on the way up.
• Maintain more tension through the pecs by not locking out the elbows entirely.

3. Dumbbell fly

The dumbbell fly utilizes a chest fly movement pattern to isolate the muscles of the chest, help the muscles to grow better and become stronger.

The dumbbell fly takes advantage of arm rotation to really target all areas of the pecs, but most significantly the inner chest.

It is often thought of as a classic bodybuilding movement, as the goal of the exercise is to isolate the chest for aesthetic purposes.

Try other variation of chest fly to train inner chest muscles:

• Incline dumbbell fly
• Incline cable fly
• Cable fly

How To Do

1. Lie on the flat bench with your feet flat on the floor.
2. Lift your arms straight up from your shoulders and the dumbbells directly over your upper chest.
3. Slowly lower your arms out to your sides until your wrists come to about shoulder level or slightly above.
4. Bring your arms back toward the centre line of your body, focusing on using your pec muscles to draw them back together.

Tips

• Perform press in a controlled manner.
• Keeping the tension on the inner chest during every single rep.

4. Dumbbell Pullover

The classic dumbbell pullover is a widely used resistance exercise that primarily strengthens the muscles in the chest and back.

It also engages the large wing-shaped muscles in the back (latissimus dorsi), the core muscles, and the triceps.

It involves lying down on a bench and moving a dumbbell over your head, while maintaining a slight bend in your elbows. They are an excellent addition to your upper body strength routine.

Variations Of Pull-Over That Help To Grow Inner Chest

• Barbell pullover
• Cable pullover
• Incline pullover
• Decline pullover
• Swiss ball dumbbell pullover

How To Do 

1. Lie across on a bench on your shoulders so that your head is hanging.
2. Grasp a dumbbell with both hands and get it straight over your chest.
3. Lower the dumbbell in an arc slowly, getting a good stretch in your rib cage.
4. Lower the dumbbell as far as possible and then raise it back to the starting position.
5. Repeat for your desired number of reps.

Tips

• Maximum stretching ensures the greatest expansion of the rib cage.
• Use a weight that challenges you, but allows you to maintain proper form.
• Relax your hips and let them fall, as relaxed hips help in extra expansion.
• Keep your core tight and your lower back flat against the bench.

5. Landmine Chest Press

If you’re looking for a way to get more creative with your inner chest workout, why not try the landmine chest press?

The landmine press is not a popular exercise yet provides many benefits in regard to progressing your inner and upper chest.

It can be performed in a kneeling position, which increases core involvement and can improve core stability and strength of the abdominal muscles. It’s one of my favorite exercises to train the inner chest muscles.

How To Do

1. Place a barbell in a landmine holder or set up a barbell in a corner.
2. Then add weight plates to the free end of the barbell.
3. Assume a half kneeling position with the knee under your hip, toes tucked, and rib cage down.
4. Press the barbell up straight in front of you until your arms are extended, avoiding hyperextension at the elbows.
5. Hold the weight for a second and focus on contracting your chest muscles.
6. Slowly lower the weight back towards your chest and then repeat for the recommended reps

Tips

• To secure the barbell, you can interlock your hands around the bar.
• Lean your body forwards slightly and engage your core muscles to help with stabilization.
• Exhale on pushing movement, inhale when returning to the starting position.
• Contract the chest muscle at the top of the movement.

6. Smith Machine Hex Press

The Smith machine hex press allows for greater range of motion and more emphasis on the inner chest muscles compared to a traditional bench press. It gives effective engagement and excellent weight distribution.

However, it is challenging to organize and requires a lot of attention and detail to perform this workout.

How To Do

1. Set up a Smith machine with the bar at waist height.
2. Lie on a bench with your feet flat on the ground, and position yourself underneath the bar.
3. Grip the bar with the V-Bar handle and slowly lift it off the rack.
4. Press them straight out in front of your chest.
5. Lower the weights under control. Then repeat the desired number of reps.

Tips

• Focus on powerful contractions and slow eccentric.
• Perform press in a controlled manner.
• Focus on mind-muscle connection

7. Pec Deck Fly

The pec deck fly is an isolation exercise that primarily targets the chest muscles, including the inner chest. It is a popular exercise in gyms and fitness centres because it isolates the chest muscles. This means that the exercise only works the chest muscles without actively working the triceps or shoulders.

This exercise provides a smooth and controlled movement, resulting in a more focused and intense workout. It is used in strength training and bodybuilding routines to build bigger and stronger chest. My main focus when doing this exercise is to create a mind-muscle connection in order to maximize the exercise output.

The pec fly is a great exercise for both beginners and experienced athletes to target the inner chest muscles without worrying about balance.

EMG data shows that machine fly and bench press both activate the pectoralis major muscle to a similar degree, making them both effective exercises for chest growth.

How To Do

1. Sit on the pec deck machine and adjust the seat so that the handles are at chest level.
2. Place your forearms on the padding. Keep your body fixed, slowly bring the forearm pads or handles together.
3. Focus on contracting your inner chest muscles.
4. Hold the contraction for a moment, then slowly release back to the starting position.
5. Repeat for the desired number of reps.

Tips

• Your upper arms should be parallel to the floor.
• Keep your eyes straight ahead while performing the exercise.

8. Cable Crossover

The Cable Crossover is a resistance training exercise that primarily targets the inner chest muscles. The exercise involves using cable machines to perform a fly-like motion with the arms, crossing them in front of the body.

The cable provides constant resistance, and helps in developing central chest muscles, and provides the much-needed stress on inner pecs.

Other Variations Of Cable Crossover

• High Cable Crossover: Set the cables to a high position to target the lower chest muscles
• Low Cable Crossover: Set the cables to a low position to target the upper chest muscles.
• Single-Arm Cable Crossover: Perform the exercise one arm at a time to increase stability and engage the core muscles.

How To Do

1. Start by setting the cable machines to the desired height and weight.
2. Stand between the two cable machines and grasp the handles.
3. Step forward with one foot, and lean slightly forward at the hips.
4. Keeping the arms straight but not locked, bring the handles together in front of the body, crossing them at the wrists.
5. Slowly lower the arms back to the starting position, maintaining control and tension in the chest muscles.
6. Repeat for desired number of repetitions.

Tips

• Keep the core engaged and the back straight.
• Avoid arching the back or rounding the shoulders.
• Use a weight that allows for proper form and controlled movements.

9. Single Arm Chest Fly

When doing an inner chest workout with a cable machine, there are plenty of single-arm chest exercises you can add to correct potential imbalances.

During exercise, emphasis is placed on bringing the resistance further across the body and past the midline, thus extending the range of motion to force an intense peak contraction in the inner pec.

How To Do

1. Begin by moving the pulleys to the high position, select the resistance to be used, and take a handle in one hand.
2. Extend your arm and make sure to have a slight bend in your elbow.
3. Pull your hand to the centre line of your chest while keeping your upper body straight.
4. Hold for a second, and go back to the starting position to complete one rep.

Tips

• Always keep the elbows slightly bent for full inner pec activation.
• Keep a controlled motion and avoid jerky movements.

10. Plate Squeeze Press

The plate squeeze press is a great option for adding to your chest workout regimen to increase muscle hypertrophy, and create chiselled and defined pectorals.

It is an alternative and free weight exercise that primarily targets the inner and upper chest, and to a lesser degree that also targets the shoulders and the triceps.

How To Do

1. Grab 2–3 plates and squeeze them together with your palms.
2. Bring the plates to the centre line of your chest, extend your arms forward and slightly upward.
3. Contract your chest as hard as possible. Maintain tension on the inner and upper chest.
4. Reverse your arms in the exact same movement pattern.

Tips

• Use a controlled tempo to push your arms up and forward.
• Remember to breathe properly.

Common Mistakes To Avoid When Training the Inner Chest

Training the inner chest can be challenging, and it’s essential to avoid certain common mistakes to get the best results.

1. Focusing solely on isolation exercises

While isolation exercises like cable crossovers and pec deck flyes are useful for targeting the inner chest.

It’s essential to incorporate compound exercises like bench presses and push-ups to stimulate overall chest growth.

2. Neglecting proper form

To target the inner chest effectively, it’s crucial to perform exercises with the correct form.

Failing to do so can put undue stress on other muscle groups and limit the effectiveness of the exercise.

3. Ignoring progressive overload

To continue making gains, it’s essential to gradually increase the weight or reps you’re using to challenge your chest muscles. Failing to do so can lead to a plateau in progress.

4. Not giving your muscles enough time to recover

Overtraining your inner chest can lead to fatigue, soreness, and even injury. It’s important to give your muscles enough time to rest and recover between workouts to avoid overtraining and maximize your gains.

5. Overemphasizing the squeeze

It is important to emphasize the contraction and squeeze of the inner chest, but excessive emphasis can lead to decreased range of motion and limit the overall effectiveness of the exercise.

6. Forgetting about nutrition

Proper nutrition, including adequate protein intake, is crucial for muscle growth.

Neglecting this aspect of your training can limit your results, no matter how hard you work in the gym.

How To Build Inner Chest?

The inner chest can be a stubborn area to build, since it has bigger and stronger fibers that require a lot more work to grow.

A well-developed inner pec makes the chest look bigger and more complete, showing that you are a serious lifter who has worked hard at the gym.

There are ways to target the inner pec fibers, but it is not possible to separate one part of a muscle.

1. Focus on mind-muscle connection

Mind-muscle connection refers to the ability to mentally focus on the muscles you’re working during an exercise.

This technique can help you isolate and activate your inner chest muscles more effectively.

Focus on feeling the contraction in your inner chest muscles during each repetition.

2. Focus on exercises that target the inner chest

To train your inner chest, you need to focus on exercises that emphasize this area.

Examples of such exercises include dumbbell flyes, dumbbell pullovers, cable crossovers, close-grip bench press, and push-ups with hands close together.

3. Use different rep ranges

Add different rep ranges into your workouts can help you target different muscle fibers and promote muscle growth.

Try doing both low-rep sets (4-8 reps) and high-rep sets (15-20 reps) into your chest workouts.

4. Add Variations

To train the chest from different angles, try using different types of equipment, such as a dumbbell, barbell, or plates, for performing exercises.

Tip and Technique To Maximize Inner Chest Gain

To effectively train the inner chest, it’s important to focus on both training volume and technique. Here’s what you need to know:

1. Optimize Training Volume

Training volume refers to the total amount of work you perform during a workout, including the number of sets, reps, and weight used.

Of course, the number of sets and reps will be determined based on your fitness journey, but here is a great starting point.

Sets

According to the latest scientific evidence, 12–20 weekly sets per muscle group may optimize muscle growth.

• Beginners: ~10 sets per week.
• Intermediate: ~15 sets per week.
• Advanced: ~20 sets per week.

When a certain amount of volume stops being effective and your progress stalls, you can add sets to increase volume and use that as a driver of renewed progress. 

Reps

The best rep ranges and loads to work with.

• For muscle endurance: Aim for 15-20+ reps, with a moderate amount of resistance.
• For muscle strength: 6-10 reps, with a heavier amount of resistance.
• For muscle hypertrophy (increased muscle size): Aim for 3-4 sets of 8-12 reps, with a moderate to heavy amount of resistance.

It is always best to start with a lower number of reps and sets, and then gradually increase as your strength improves

2. Progressive Overload

This is the principle of increasing resistance across sets and workouts. You can increase the weight from set to set, but keep it minimal to maintain the rep range.

The load should bring you to or near failure within the given rep ranges to be effective.

You’ll find a way to incorporate most of, if not all, into your chest routine. Variety promotes gains in strength and size, and helps to prevent plateaus. The chest responds well to variety.

3. Grip and Hand Position

While training your inner chest, grip and hand positioning is important.

The inner chest muscles work hard, when you place the hand closer than the shoulder width and squeeze the chest near the top.

Keeping your arms slightly wider than shoulder width is perfect for overall chest development.

4. Incorporate Compound Exercises

Compound exercises like bench presses and push-ups should form the foundation of your chest workout, as they engage multiple muscle groups.

Start with heavy compound exercises and finish with isolation exercises.
