Big arms are a status symbol. People usually obsess over biceps because they’re the "mirror muscle," but that's a mistake. If you want sleeves that actually feel tight, you need to focus on tricep training for mass. Think about it. The triceps brachii makes up roughly two-thirds of your upper arm volume. It’s the literal foundation of arm thickness. If your triceps are flat, your arms look like noodles from the side, no matter how many curls you do.
I've seen guys spend years hammering cable pushdowns without gaining an inch. It’s frustrating. They show up, do three sets of ten, feel a little burn, and go home. That isn’t how growth works. Muscle hypertrophy—especially in a complex, three-headed muscle group—requires a specific blend of mechanical tension, metabolic stress, and, frankly, a bit of structural anatomy knowledge that most gym-goers ignore. You can't just move weight; you have to understand how the lateral, medial, and long heads actually function.
The long head is the secret. It’s the only part of the tricep that crosses the shoulder joint. This means if you aren't doing overhead movements, you’re leaving half your gains on the table. It's honestly that simple.
The Anatomy of Massive Triceps
To understand tricep training for mass, you have to look under the skin. The triceps brachii has three distinct heads. You have the lateral head, which sits on the outside and gives you that "horseshoe" look. Then there’s the medial head, which is deeper and mostly contributes to stability and overall thickness near the elbow. Finally, the long head is the beast that sits on the back and inner side of the arm.
Because the long head attaches to the scapula, it only gets fully stretched when your arms are over your head. This is why "skull crushers" or overhead extensions feel so much harder than standard pushdowns. Research, including studies by sports scientists like Dr. Brad Schoenfeld, consistently shows that training a muscle at long muscle lengths (the "stretch") is a primary driver for hypertrophy.

Most people fail because they stick to the midrange. They do pushdowns. They do close-grip bench. These are great, but they don't challenge the muscle at its most vulnerable, stretched position. If you want density, you have to embrace the stretch.
Why Your Current Tricep Routine Is Failing
Let's be real. Your triceps are probably stubborn because you're treating them like an afterthought at the end of a chest day. By the time you get to them, your central nervous system is fried from heavy pressing. Your elbows are cranky. You end up doing some half-hearted "ego lifting" on the cable machine using your body weight to shove the bar down.
That isn't tricep training. That's just using your lats and gravity.
True tricep training for mass requires isolation. You need to keep the shoulders still. If your elbows are swinging back and forth like a pendulum during extensions, your lats are doing the work. Stop it. Pin your elbows to your ribs or keep them fixed in space.
Another issue? Lack of variety in resistance curves. Cables are amazing because they provide constant tension. Dumbbells are great because they allow for a natural range of motion. Barbells let you overload with massive weight. If you only use one of these, you’re missing out. A well-rounded program uses all three to hit the muscle from every conceivable angle.
The Big Three Movements for Growth
If I had to pick only three exercises for the rest of my life, the list would be short.
- The Weighted Dip. This is the "squat" of the upper body. It allows for the highest level of mechanical tension. If you can dip with two plates hanging from your waist, you will have big triceps. Period.
- The JM Press. Named after JM Blakley, this is a hybrid between a close-grip bench press and a skull crusher. It allows for heavy loading while putting the triceps in a massive mechanical disadvantage. It’s brutal on the elbows if you jump in too fast, so start light.
- Overhead Cable Extensions. Using a rope on a cable stack allows you to pull the ends apart at the top, achieving a peak contraction while the long head is fully lengthened. It’s the perfect "finish" exercise.
Don't overcomplicate it. You don't need twenty different "fancy" variations you saw on Instagram. You need these staples performed with violent intensity and perfect form.
Mastering the Long Head Connection
We need to talk more about that long head. It’s the key to tricep training for mass that actually changes your physique. Since the long head originates at the infraglenoid tubercle of the scapula, its function isn't just elbow extension; it's also shoulder adduction.
This means when you do an overhead extension, you aren't just working the tricep; you’re putting that specific head under a massive amount of tension it doesn't get elsewhere.
Try this: Sit on a bench with a single heavy dumbbell. Hold it with both hands and lower it behind your head until you feel a deep, almost uncomfortable stretch in your armpits. Hold that for one second. Then, explode up. That "bottom" portion of the rep is where the growth happens. Most people cheat and only do the top half. They’re missing the point.
Frequency and Volume: Finding the Sweet Spot
How often should you hit them? There’s a lot of debate here. Some guys swear by "bro splits" where they hit arms once a week until they can't brush their teeth. Others prefer high frequency.
Honestly, the sweet spot for most natural lifters is hitting triceps 2-3 times per week.
Think about it this way: The triceps are involved in every single pressing movement you do. If you do bench press on Monday and shoulder press on Thursday, your triceps are already getting stimulated. Adding a few sets of direct isolation work after those sessions is usually enough. Total weekly volume should probably land between 10 and 15 hard sets.
If you go above 20 sets, you're likely just doing "junk volume." You're tired, the weight is light, and you're just chasing a pump. A pump is fun, but it doesn't always equal growth. Progressive overload—adding weight or reps over time—is what actually builds the tissue.

Dealing With "Elbow Health"
You can't train for mass if your joints are screaming. Tricep training is notorious for causing tendonitis, specifically at the "bony" part of the elbow. This usually happens because of two things:
- Going too heavy on skull crushers with a straight barbell.
- Lifting with cold joints.
Pro tip: Never start your arm workout with heavy free-weight extensions. Start with a cable pushdown for 2-3 sets of 15-20 reps. Get the synovial fluid moving. Get blood into the area. Once the elbow feels "greased," then you can move on to the heavy stuff. Also, consider using an EZ-curl bar instead of a straight bar; the slight angle saves your wrists and elbows a world of hurt.
Sample Routine for Size
If you're stuck, try this specific sequence twice a week. It’s designed to hit all three heads and prioritize the stretch.
Day A (Power Focus):
- Close Grip Bench Press: 3 sets of 6-8 reps. Keep your elbows tucked, not flared.
- Weighted Dips: 3 sets of 8-10 reps. Stay upright to keep the focus on the triceps, not the chest.
- Single Arm Cable Pushdowns: 2 sets of 12-15 reps. Focus on the squeeze.
Day B (Hypertrophy/Stretch Focus):
- JM Press: 3 sets of 8-10 reps.
- Overhead Dumbbell Extension: 3 sets of 10-12 reps. Really accentuate the stretch at the bottom.
- Cable Rope Pushdowns: 3 sets of 15 reps. Flare the rope ends apart at the bottom of every rep.
This isn't a "get big quick" scheme. It’s a blueprint. You have to eat. You have to sleep. Most importantly, you have to track your lifts. If you’re doing the same weight for the same reps six months from now, your arms will look exactly the same.
The Role of Mind-Muscle Connection
It sounds like "bro-science," but the mind-muscle connection is backed by actual data in the context of isolation movements. In tricep training for mass, you have to feel the muscle contracting. Because the tricep is on the back of your arm, you can't see it working. You have to internalize the movement.
Visualize the muscle fibers shortening as you straighten your arm. Don't just "push the weight." Think about "extending the elbow." It’s a subtle mental shift that changes how your nervous system recruits the motor units.
Final Actionable Steps for Growth
Stop guessing. If you want to take your triceps to the next level, start implementing these three things today. First, prioritize overhead work. If your routine doesn't include a movement where your elbows are above your shoulders, you are failing the long head. Second, increase your frequency. Move from once a week to twice, but lower the volume per session so you can recover. Third, fix your form. Stop using momentum. If you have to swing your body to get the weight down, it’s too heavy.
Focus on the deep stretch, control the eccentric (the lowering phase), and add weight to the bar whenever your form allows. Massive triceps aren't a gift; they're the result of consistent, intelligent mechanical tension. Get to work.

Your Next Steps:
- Audit your current split: Ensure you have at least one heavy compound press (dips or close-grip bench) and one overhead extension.
- Start a log: Record your current weights for these movements. Aim to add 2.5kg or one extra rep every two weeks.
- Prioritize recovery: Triceps are small muscles but they get taxed heavily. If your elbows feel sharp pain, swap barbells for cables for two weeks to allow the tendons to desensitize.
- Eat for growth: You cannot build significant mass in a caloric deficit. Ensure you are in a slight surplus with at least 0.8g to 1g of protein per pound of body weight.
