You’re here because you want to build a chest that enters the room before you do, am I right? You’re tired of pecs that look like they belong on a marathon runner.
You don’t need 20 chest exercises. You don’t need to shock the muscle every Monday.
A thick, full chest is built with a few exercises that actually work, progressive overload, enough volume, and the patience to train hard long enough for your efforts to bear pec fruit.
Let’s do it.

Chest Anatomy & Function: What You’re Building
Before you start throwing weight around, you need to know what you’re trying to grow.
Let’s lift the hood and look at the anatomy and mechanics of your chest muscles (there are not one, not two, but four of them).
Don’t worry, you’re not in for a long-winded lecture. We’re going to keep moving so we get to the fun part – training – asap.
Pectoralis Major
This is the big boss: the big, fan-shaped muscle you can see and flex in the mirror.
The pec major battles it out with the lats for the honor of being the single largest upper-body muscle in most people (the delts and triceps have it beat, but they consist of three muscles each, so they’re kind of cheating).1
It’s also the muscle you need to grow to build a big chest.
Even though the pec major is one single muscle, the muscle fibers run in different directions, dividing it into two main “heads”:
- The Clavicular Head (Upper Chest): These fibers start up at your clavicle (collarbone) and run diagonally down to attach to your upper arm bone (humerus).
- The Sternocostal Head (Mid/Lower Chest): This guy makes up the majority of your pec. Its fibers start at your sternum (breastbone) and ribcage, running horizontally to attach to your humerus right next to the upper chest fibers.
- (Bonus) The Abdominal Head: Some textbooks separate the very bottom fibers of the sternocostal head into an “abdominal” head. That’s the very bottom ridge of your lower chest.
Pectoralis Minor
The pec minor is a much smaller, triangular muscle underneath the pec major.
It attaches from your 3rd, 4th, and 5th ribs up to a little bony hook on your shoulder blade called the coracoid process.
Serratus Anterior & Subclavius
In addition to the big boys (well, one big and one small boy), we also have the serratus anterior on the side and front of your ribcage and the tiny subclavius right under your collarbone, which also belong to the pec family.
What Do Your Pecs Do?
Your pecs move and stabilize your shoulder and upper chest.
Pectoralis Major
The pec major pulls your arm across the body, helps bring it down from overhead, and rotates it inward. We’re talking pushing, hugging, or throwing motions.
Or, translated into gym speak, doing chest presses and flyes (usually not much throwing going on in the weight room, unless you’re an athlete doing bench press throws (it’s a thing)).
Pectoralis Minor
The pec minor doesn’t move your arm directly. Its job is to pull your shoulder blades down and forward.
Example: If you’re doing push-ups, it helps manage your shoulder blades so the pec major can do the pushing.
Serratus Anterior
The serratus anterior works with the pec minor to keep your shoulder blade stabilized against your ribs and helps you punch someone in the nose (hence its nickname “boxer’s muscle”).
You can see it in the wild when a bodybuilder in contest shape hits a front lat spread, rippling just below their armpits.
Subclavius
The subclavius doesn’t move much, but it does anchor your collarbone in place and protects nerves and blood vessels below.
Training to Grow Your Chest
Your pecs grow like any other muscle. You need mechanical tension (the biggest factor for building muscle) and to do more and harder work over time (progressive overload).
That means you should focus on three things come chest day:
- Heavy pressing to overload your pecs
- Getting a good stretch and a good contraction (full ROM)
- Isolation work to remove other muscles from the equation
And a big bench doesn’t automatically mean you’ll build a big chest.
It can help, sure, but only if you actually press with your chest. Plenty of guys can bench a Fiat Topolino and still have so-so pecs because their front delts and triceps overpower every rep.
Your goal is not to move weight from point A to point B.
Your goal is to force your pecs to do as much of the work as possible.
That being said, you do need to get stronger. If you lift the same weight for the same reps for a year, guess what? You’ll look pretty much the same a year from now.
The Best Exercises to Build a Big Chest
Your chest doesn’t know whether you’re using a barbell, a dumbbell, a machine, or cables. It knows effort and progression.
And don’t need an arsenal of more or less obscure presses and flye variants to build your pecs.
Instead, you just need a few great exercises.
Exercises that are stable and let you load your pecs through a full range of motion, with a good stretch and contraction.
1. Bench Press
For pure mass, it’s hard to beat the classic heavy chest builder: the bench press.
You can move a lot of weight, and it’s easy to add weight to the bar in small increments. Plus, it’s both fun and easy to track your strength gains over time.
And yes, I include machine chest presses here.
A high-quality chest press machine is phenomenal for building your pecs because you don’t have to stabilize and can push your pecs to failure safely.
How to Bench Press
- Lie on the bench, pull your shoulder blades together and down, and slightly arch your back.
- Grip the bar slightly wider than shoulder-width apart.
- Inhale, hold your breath, and unrack the bar.
- Lower the bar with control until it touches your chest somewhere close to your sternum.
- Push the bar up to the starting position while exhaling.
- Take another breath while in the top position, and repeat for reps.
2. Dumbbell Chest Press
If I had to choose between the barbell bench press and the dumbbell chest press for building a big chest, it would be tight, but the dumbbells would come out on top, despite the fact that they’re awkward to get into position once you’re decently strong.
Why? Longer range of motion and kinder to the shoulders. The latter sounds like a non-issue when you’re 20 and invincible, but not when you’re 40 with joints full of gravel.
How to Dumbbell Chest Press
- Lie on a bench, and lift a pair of dumbbells up to the starting position.
- Press the dumbbells up to straight arms, while exhaling.
- Inhale at the top, or while lowering the dumbbells with control back to your shoulders.
- Repeat for reps.
3. Incline Dumbbell Press
The incline dumbbell press is my favorite exercise for the upper chest. You may disagree, and it’s fine if you do, but this is one exercise where I feel the dumbbell version is superior to the barbell variant.
Dumbbells let your arms move more naturally, and you get both a deeper stretch and a better chest contraction. And (hard to explain) it just feels better.
Set the bench to a 30–45 degree angle (any higher and you start using too much front delt).
How to Incline Dumbbell Press
- Adjust the incline of a bench to 30–45 degrees.
- Sit down and lift a pair of dumbbells to the starting position.
- Press the dumbbells up to straight arms while exhaling.
- Inhale at the top or as you lower the dumbbells with control back to your shoulders.
4. Incline Smith Machine Press
It’s easy to scoff at the Smith machine, but doing incline chest presses on one is underrated. Maximum stability, pushing to failure without worrying about balance or setup – what’s not to like?
I prefer a higher incline here than with dumbbells – still in the 30–45 degree range, but closer to 45 than 30. It’s easier to keep the shoulders back and down and focus on the upper pecs when the fixed path of the machine and stability have your back.
How to Smith Machine Incline Bench Press
- Sit on an inclined bench, pull your shoulder blades together and down, and hold your chest up.
- Grip the bar slightly wider than shoulder-width apart.
- Take a breath and hold it, and unrack the bar.
- Lower the bar with control until it touches your upper chest.
- Push the bar up while exhaling.
- Take another breath in the top position, and repeat for reps.
5. Dips
Dips – the squat of the upper body. A cliché? Absolutely. But not without a grain of truth. When you can crank out sets of 10 weighted dips with good form, chances are your pecs have the size to match your strength.
Dips can be either a chest exercise or a triceps exercise, but if you lean forward a bit and flare your elbows out a little, you make your chest do more of the work.
Go down until you feel a good stretch in your chest (but not deeper than your shoulder mobility allows). When I say full ROM in this exercise, I mean the full ROM of your chest muscles, not your shoulder joint.
How to Do Dips
- Grip a dip station about shoulder-width apart, and climb or jump to get into the starting position.
- Lower yourself with control until your shoulder is below your elbow, or as deep as you comfortably can.
- Reverse the motion and return to the starting position.
6. Cable or Machine Chest Fly
Both the cable chest fly and the machine chest fly land in the top echelon of chest isolation exercises, no doubt.
Better than dumbbell flyes, you say? Indeed. Unlike dumbbells, cables or a machine keep full tension on your chest through the movement, especially at the top, where you can squeeze your pecs much better (because gravity only pulls dumbbells straight down).
The crème de la crème of the two? Depends. A really good chest fly machine takes the proverbial pec cake, although a badly constructed one can feel terrible (while cables are always cables).
How to Do Cable Chest Flyes
- Fasten a pair of handles in the top position of a cable cross. Grip the handles, step forward, and lean slightly forward.
- With just a slight bend in the arms, push the handles forward until they meet in front of your body.
- With control, let the handles go back to the starting position.
- Repeat for reps.
How to Do Machine Chest Flyes
- Adjust the back support and handles so you can grip them at shoulder height and get a full range of motion.
- With just a slight bend in the arms, push the handles forward until they meet in front of your body.
- With control, let the handles go back to the starting position.
- Repeat for reps.
Top Tips for Building a Big Chest
Getting your pecs to grow requires more than heaving the heaviest barbell you can find.
Give my top tips a try if you’re having trouble building your chest. Heck, even if you don’t.
1. Prioritize Incline Work
Have you ever seen anyone sporting an overdeveloped upper chest? I didn’t think so.
Your upper chest, that’s what makes your pecs impressive from the front and side. Without it, even a massive chest looks droopy.
Any variation of an incline press or fly works. Use a moderate incline, around 30–45 degrees. Too high, and you turn your upper chest builder into a shoulder press.
Also, if your upper chest is lacking, make sure you prioritize it. Train it hard early in your chest workout when you’re fresh.
2. Don’t Cut Your Range of Motion Short
One of the best ways to make sure your pecs stay puny is to do shallow half-reps.
Your pecs get a neat growth stimulus from the stretch at the bottom. If you stop every press several inches above your chest (a very common sight in most gyms), or do flyes where your arms barely move behind your torso, you need to press the reboot button.
Now, I’m not talking about forcing maximum joint ROM or wrecking your shoulders in the process. I’m talking about the longest productive range you can control.
Not locking out your presses, on the other hand, has its place in bodybuilding-style training. If you prefer doing your reps that way, do it, but don’t skimp out on the bottom stretch.
3. Get Strong in Moderate Rep Ranges
For building muscle, you don’t need to max out. You don’t need to get powerlifter-strong. You need to get stronger in rep ranges that actually build muscle.
Most of your chest work “should” stick to the 6–12 rep range for presses and the 10–20 rep range for flyes and isolation work.
Note that I said “should,” not should. These are my tips – what I’ve found to work the best – not universal truths.
Can you train like a powerlifter and build a big chest? Of course. Just look at the strongest guys.
But if you’re not looking to compete, a higher rep range is usually more effective (for most) and safer in the long run.
Try this:
- Press heavy enough that you reach failure somewhere in the 6–12 rep range.
- Isolate with a weight that allows you to get 10–20 clean reps before the burn gets out of hand.
You should always try to progress over time. More reps with the same weight. More weight for the same reps. Stricter reps with the same load.
But not sloppy progress. Adding weight to the bar while shortening your ROM or bouncing the bar off your sternum is fake progress.
4. Train Close to Failure
If you want a big chest, you need to train hard. I suggest you take the majority of your working sets to 0–2 RIR: you either reach failure or stop just before your form breaks down.
Many lifters call it quits when a set starts to hurt, not when their pecs are actually near failure. To build real muscle mass, you have to be able to push through that burn and fatigue.
For heavy presses, I suggest stopping ~1–2 reps short of failure. But for machines and cables, you can go all the way more often because your technique is less likely to break down. And the risk of hurting yourself is lower, too.
Pecs respond great to high intensity and high effort, but only as long as you keep the tension on them.
I’m talking about intermediates and above here, not beginners. If you’re a beginner, you need to focus on form and learning to feel the movements first and foremost. You don’t need failure.
Check out my in-depth article for more about the benefits and drawbacks of training to failure:
Training to Failure: Is It Necessary for Muscle Growth & Strength?
5. Try Advanced Training Techniques
If you’re having trouble gaining chest size despite training hard and using good form, try adding advanced techniques like drop sets or myo reps.
- For the drop set approach, end your last isolation set by stripping 20–30% of the weight and going again immediately. Once per workout is plenty.
- For myo-reps, same deal: after your last isolation set, rest 10–20 seconds, then do several more mini-sets with the same weight until you reach complete failure. For example, 12 + 5 + 4 + 3 reps, and that’s your myo set.
There is little research to support these methods being better than straight sets for building muscle, but if you’re already doing everything else as right as possible, I believe they can help you get into the growth zone.
At the very least, you get a nasty pump. And that’s not half bad.
6. If Once Isn’t Working, Try Twice
I like a good bro split (a body part split where you train each muscle group once per week on a dedicated arm, leg, or chest day) as much as the next guy. Heck, it’s my favorite bodybuilding split.
However, if your chest isn’t growing, hitting your pecs more often could be worth trying.
A single massive chest day definitely works, as long as you get enough quality sets in. But therein lies the potential rub.
If you hit chest twice, you can get more high-quality sets without cramming everything into one session, where your performance tanks after the first few exercises.
For example:
- One heavier chest workout with plenty of presses.
- One pump-focused day with more machines, cables, and higher reps.
Around 10–20 hard sets per week for chest is the sweet spot, according to research (and my experience).2 3
Unless you’re already familiar with high-volume chest training, start near the lower end and move toward the higher end, a set or two every few weeks.
Volume is a big driver of hypertrophy (not the biggest, but still important), but more isn’t always better. Better is better.
The Best Workouts for Building a Big Chest
Ready to put it all together?
Here, I’m going to present two great chest workouts for your pec pleasure: one intermediate-level workout and one more advanced bodybuilding-style workout.
Either one is designed to get your chest growing (and make you stronger in the process).
StrengthLog’s Chest Workout
This is a 4-exercise workout that blasts your pecs from every angle and with both heavy, low-rep presses and high-rep isolation work.
- You start with two free-weight presses: heavy bench for size and strength, followed by incline dumbbell work for your upper chest.
- Then, your lower chest gets its comeuppance with dips before you finish off with cable isolation and a nice pump.
Do this workout 1.5–2 times a week (e.g., a Push/Pull/Legs split) for best results.
| Exercise | Sets | Reps |
|---|---|---|
| Bench Press | 3 | 5 |
| Incline Dumbbell Press | 3 | 8 |
| Dips | 3 | 12 |
| Cable Chest Fly | 3 | 15–20 |
Start the Chest Workout in the StrengthLog app.
Bodybuilding Chest Workout
This 5-exercise workout gives your chest a thrashing it won’t soon forget, with a combination of compound exercises and isolation movements to target every pec fiber for complete development.
- Again, you start with presses: flat dumbbell presses, followed by incline machine presses.
- After blasting your upper pecs, you switch to dips for more lower chest focus, followed by cable flye isolation.
- You finish in style with an old-school favorite, the dumbbell pullover.
The Bodybuilding Chest Workout works great both as a once-weekly bro split-type workout and as part of a program with higher frequency (1.5–2x/week).
| Exercise | Sets |
|---|---|
| Dumbbell Bench Press | 4 |
| Smith Machine Incline Bench Press | 4 |
| Dips | 3 |
| Cable Chest Fly | 3 |
| Dumbbell Pullover | 2 |

Eating to Build Your Chest
If your nutrition is garbage, your chest isn’t going anywhere, no matter how much time you spend bench pressing week in and week out.
To add serious pec mass, you need the calories and the protein to support the process.
A small calorie surplus is best (but you want at least calorie balance). You don’t need to go on a dirty bulk that just adds inches around your waist, but you do need to give your body the resources it needs.
If you’re not getting stronger, your pumps are noticeably absent, and your bodyweight hasn’t moved in months, your hardgainer chest genetics might just be under-eating.
Beyond calories in general, you also need plenty of protein. Good sources include chicken, turkey, beef, eggs, Greek yogurt, cottage cheese, fish, tofu, tempeh, protein powder, lentils, and beans.
Can you build a big chest and lose fat at the same time?
Well, you can build a bigger chest in a deficit, but it’ll only work really well if you’re a beginner or if you carry a lot of body fat.
Expect slower progress if you’re in a fat-loss phase.
Our calculators can help:

- Protein calculator: find out how much protein you need to grow.

How Long Does It Take to Build a Big Chest?
Train right, and your pecs can expand impressively fast. Especially if you’re a beginner.
In one study, untrained young men benched thrice weekly and increased their chest muscle size by 43% in five months.4
Now, a 43% increase of very little doesn’t equal big pecs, but the point is that you can add size quickly.
Of course, the longer you train, the slower the gains will come. Still, even with average genetics, both you and everyone who glances at you should notice a significant difference in less than a year (although if we’re talking competitive bodybuilder big, expect the process to take 5 years or longer).
Final Rep
There’s no secret exercise, magic angle, or hidden supplement for building a bigger chest.
It’s just train hard, eat enough, and recover. It’s a simple formula, but simple works.
Feel free to download the StrengthLog workout app and give one of our chest workouts a spin. Put in the work, and watch those chest gains roll in.
