If You Want Bigger Traps, Here Are 5 Exercises for More Defined Shoulders According to Research
Ask someone in the gym to point to their trapezius muscles, and they’ll probably gesture toward the small mounds nestled between their neck and shoulders—but that’s really just the tip of the iceberg. Your traps are actually a diamond-shaped group of muscle fibers that extend from the sides of your neck to your shoulders and down to a point at around your mid-back, covering about a third of the visible muscle on your back.
Developing your traps is more than just aesthetics. Strengthening your traps can prevent injuries in and out of the gym and even help protect your neck from the posture-destroying effects of staring at your phone. Plus, if you want a big, shapely back that fills your shirt, you need to give attention to trap exercises.
Training the traps is essential for increasing strength across your compound lifts and improving poor posture. The traps are what pull the head and neck back, helping prevent kyphosis—that forward curvature of the spine often called “tech neck.”
Here are five research-backed exercises that will build bigger traps and create more defined shoulders.
Trap Bar Deadlift
Deadlifts require you to recruit back muscles—namely, your traps—to hang onto the weight as your big leg muscles work to raise it off the floor, making this a total-body, trap-heavy exercise. The trap bar allows for a more neutral spine position and reduces stress on the lower back while still maximally engaging the traps.
Why It Works
The trap bar deadlift forces your traps to work as stabilizers throughout the entire movement. As you lift the weight, your traps fire to keep your shoulders packed and prevent the weight from pulling you forward. This constant tension builds both size and strength in the upper, middle, and lower portions of the trapezius.
How to Do It
- Stand inside the trap bar with feet hip-width apart
- Grip the handles with arms straight
- Brace your core and push through your heels to stand up
- Keep your chest up and shoulders pulled back
- Lower the weight with control
- Perform 3-4 sets of 6-8 reps
Tips
- Keep the bar close to your body throughout the movement
- Focus on squeezing your shoulder blades together at the top
- Don’t let your shoulders round forward
Barbell Shrug
The barbell shrug is the cornerstone exercise for building trap mass. While it may look simple, proper execution is crucial for maximizing trap development and avoiding injury.
Why It Works
The shrug directly targets the upper traps through their primary function: elevating the shoulder blades. By using heavy weight through a full range of motion, you can overload the traps effectively. Research shows that the traps respond well to both heavy loads and higher volume training, making shrugs an essential movement for trap growth.
How to Do It
- Stand with feet shoulder-width apart holding a barbell in front of your thighs
- Keep arms straight and core engaged
- Shrug your shoulders straight up toward your ears
- Hold the peak contraction for 1-2 seconds
- Lower with control
- Perform 3-4 sets of 10-15 reps
Tips
- Don’t roll your shoulders—move straight up and down
- Keep your neck neutral; don’t tilt your head
- Focus on the squeeze at the top of each rep
- Avoid using momentum; control the weight throughout
Face Pull
Face pulls target the upper back, rear delts, and traps while also improving shoulder health and posture. This often-overlooked exercise is crucial for building balanced shoulder development and preventing the forward shoulder posture that plagues desk workers.
Why It Works
Face pulls work the middle and lower traps, which are often underdeveloped compared to the upper traps. By pulling the rope toward your face and squeezing your shoulder blades together, you’re working the traps in their retraction function, building thickness across the upper back.
How to Do It
- Set a rope attachment on a cable machine at upper chest height
- Grab the rope with an overhand grip, one end in each hand
- Step back to create tension
- Pull the rope toward your face, separating the ends as you pull
- Squeeze your shoulder blades together at the end
- Return to start with control
- Perform 3 sets of 12-15 reps
Tips
- Keep your elbows high throughout the movement
- Think about pulling the rope apart, not just back
- Pause and squeeze at the peak contraction
- Use a lighter weight to maintain perfect form
Farmer’s Carry
The farmer’s carry builds grip strength, shoulder stability, and trap development all at once. This functional movement translates directly to real-world strength and forces your traps to work as stabilizers under prolonged tension.
Why It Works
When you hold heavy weights at your sides and walk, your traps work overtime to keep your shoulders stable and prevent them from being pulled down by the load. This isometric contraction builds incredible trap strength and endurance. The farmer’s carry also improves posture by reinforcing proper shoulder position under load.
How to Do It
- Grab a heavy dumbbell or kettlebell in each hand
- Stand tall with shoulders pulled back and down
- Brace your core and walk forward with controlled steps
- Keep your chest up and avoid leaning to either side
- Walk for 30-60 seconds or 40-60 feet
- Perform 3-4 sets
Tips
- Start with moderate weight and build up gradually
- Focus on maintaining perfect posture throughout
- Don’t let your shoulders shrug up toward your ears
- Walk in a straight line with purpose
Dumbbell Upright Row
The upright row is a compound movement that hits the traps, shoulders, and upper back simultaneously. While this exercise has faced criticism when performed incorrectly, proper form makes it highly effective for trap development.
Why It Works
The upright row combines trap elevation with shoulder abduction, creating a powerful stimulus for upper trap growth. By pulling the weights straight up along your body, you’re working the traps through a full range of motion while also engaging the side delts.
How to Do It
- Hold a dumbbell in each hand in front of your thighs
- Pull the weights straight up along your body, leading with your elbows
- Keep the weights close to your torso
- Raise until your elbows are just below shoulder height
- Lower with control
- Perform 3 sets of 10-12 reps
Tips
- Don’t pull higher than shoulder level to avoid shoulder impingement
- Keep your core tight and avoid swinging
- Use dumbbells instead of a barbell for more natural shoulder positioning
- Focus on pulling with your elbows, not your hands
Programming Your Trap Workouts
When training traps, you don’t need to dedicate entire training sessions to them like you would other muscles. That’s because you’re likely already hitting the traps when you’re working on other muscle groups, performing heavy compound movements that use the traps as a secondary mover.
Sample Trap Training Split
Option 1: Add to Back Day
- Perform 2-3 trap-focused exercises after your main back work
- Start with a heavy compound movement (trap bar deadlift)
- Finish with isolation work (shrugs or face pulls)
Option 2: Add to Shoulder Day
- Include 2 trap exercises at the end of your shoulder workout
- Focus on movements that complement shoulder work (face pulls, upright rows)
Option 3: Pull Day
- Integrate trap exercises throughout your pulling session
- Pair trap movements with lat and bicep work
Training Frequency
The traps respond well to frequent stimulation. You can train them 2-3 times per week as long as you vary the exercises and intensity. The traps recover relatively quickly compared to larger muscle groups, allowing for higher training frequency.
Volume and Intensity
- For Strength: 3-4 sets of 4-6 reps with heavy weight (deadlifts, heavy shrugs)
- For Hypertrophy: 3-4 sets of 8-12 reps with moderate weight (most exercises)
- For Endurance: 2-3 sets of 15-20 reps or timed holds (farmer’s carries, lighter shrugs)
Common Mistakes to Avoid
Rolling Your Shoulders
Many people roll their shoulders forward and back during shrugs, thinking it provides a better stretch. This actually reduces trap activation and can lead to shoulder impingement. Instead, move your shoulders straight up and down.
Using Too Much Weight
It’s better to use moderate weight with perfect form than to ego-lift heavy weight with compromised technique. The traps respond better to controlled movements with a strong contraction than to jerky, momentum-driven reps.
Neglecting the Lower Traps
Most people focus exclusively on shrugs for the upper traps while ignoring the middle and lower portions. This creates muscular imbalances and can contribute to poor posture. Include exercises like face pulls and rowing variations to develop the entire trapezius muscle.
Forgetting About Progressive Overload
Like any muscle group, traps need progressive overload to grow. Gradually increase weight, reps, or volume over time. Track your workouts to ensure you’re making consistent progress.
Nutrition for Trap Growth
Building bigger traps requires more than just training—you need to fuel muscle growth properly:
Protein: Aim for 0.8-1 gram per pound of body weight daily to support muscle recovery and growth.
Calories: You need a slight caloric surplus to build muscle mass. Eat 200-300 calories above maintenance.
Hydration: Proper hydration supports muscle function and recovery. Aim for at least half your body weight in ounces of water daily.
Sleep: Muscle growth happens during recovery. Get 7-9 hours of quality sleep each night.
The Bottom Line
Developing impressive traps is about more than aesthetics—it’s about building a strong, injury-resistant upper body with excellent posture. By incorporating these five exercises into your training routine with proper form and progressive overload, you’ll build the kind of traps that command attention.
Remember that the traps are visible whether you’re wearing a t-shirt, tank top, or even a dress shirt, making them one of the most noticeable muscle groups you can develop. Start with lighter weights to master the movement patterns, then gradually increase the load as your strength and technique improve.
Consistency is key. Train your traps 2-3 times per week, focus on progressive overload, fuel your body properly, and give yourself adequate recovery time. Within 8-12 weeks of dedicated training, you’ll notice significant improvements in both trap size and shoulder definition.
