A solid pair of dumbbells is all you need for effective dumbbell tricep workouts that build strength and add noticeable size to your arms. With the right exercises and smart programming, you can train all three heads of the triceps and support bigger lifts like push ups and bench press.
Below, you will learn how your triceps work, the best dumbbell tricep exercises, and simple workouts you can do at home or in the gym.
Understand your triceps first
Your triceps sit on the back of your upper arm and consist of three heads: long, lateral, and medial. Together, they account for more arm mass than your biceps, so well developed triceps have a big impact on overall arm size and strength.
The main job of the triceps is to straighten your elbow and assist in pressing movements. This means every time you push a weight away from you or lock out a press, your triceps are working hard in the background.
Dumbbells are especially useful for tricep training because they allow:
- A greater range of motion
- More muscle fiber activation to stabilize the weight
- Unilateral work to correct left to right imbalances
If you want stronger, more defined arms without a lot of equipment, dumbbell tricep workouts are one of your best options.
Key benefits of dumbbell tricep workouts
When you focus on tricep training with dumbbells, you get a combination of strength, size, and control that is hard to match with machines alone.
You benefit in several ways:
- You can move your hands and wrists into comfortable positions, which reduces joint stress.
- Each arm works on its own, so your stronger side cannot secretly take over.
- You can train your triceps from multiple angles by changing body position, grip, and arm path.
- You can store a full tricep training setup in a small space at home.
Because dumbbells improve control and stability, they also help reinforce good pressing mechanics, which carries over to push ups, overhead presses, and bench variations.
When you rely only on machines and cables, your range of motion is often limited, which can reduce strength and flexibility over time. Free weights like dumbbells let you train more naturally and through a fuller arc of motion.
Best dumbbell tricep exercises
You do not need dozens of variations to build strong triceps. A small group of tested dumbbell movements can cover strength, size, and power if you perform them with good form and enough effort.
Close grip dumbbell bench press
The close grip dumbbell bench press is a staple strength builder. By holding the dumbbells close together and keeping your elbows tucked, you increase tricep involvement and reduce strain on your shoulders.
To do it, lie on a bench with a dumbbell in each hand, palms facing each other. Start with the weights over your chest and your arms straight. Bend your elbows and lower the dumbbells toward your lower chest while keeping your elbows close to your sides. Press back up by driving through your triceps and lock out with control at the top.
Because this movement allows relatively heavy loads, it is excellent for building pressing strength and overall tricep mass.
Lying dumbbell tricep extension (skull crusher)
Lying dumbbell tricep extensions, often called skull crushers, are one of the most effective dumbbell tricep exercises for hypertrophy. They place a deep stretch on the long head of the triceps, which can stimulate muscle growth when you control the movement.
Lie on a flat bench holding one or two dumbbells above your chest with your arms extended. Keeping your upper arms mostly still and elbows pointed up, bend at the elbows to lower the weight toward your forehead or slightly behind your head. Stop before your arms fully straighten at the top so that you keep constant tension on the triceps.
Move slowly and smoothly rather than jerking the weight. If you struggle to keep your arm in position, you can use your opposite hand for light support, a method also recommended by Edward R. Laskowski, M.D. at the Mayo Clinic for dumbbell triceps extensions.
Overhead dumbbell tricep extension
Overhead extensions place your arm in a position that especially targets the long head of the triceps, which contributes a lot to upper arm size and stability.
Sit or stand tall and hold one dumbbell with both hands, or one in each hand. Start with the weight overhead and your elbows close to your ears. Bend your elbows to lower the dumbbell behind your head while keeping your upper arms as still as possible. Extend your elbows to bring the weight back up without letting them flare wide.
Because your shoulders and core also have to work to keep you stable, this exercise is not only about arm size but also about better overhead control.
Dumbbell triceps kickback
Dumbbell tricep kickbacks are one of the best options for fully contracting the triceps. The arm moves behind the torso and the elbow straightens completely, which lets you shorten the tricep fibers as much as possible.
Set up by placing one hand and knee on a bench or hinging forward with both feet on the floor until your torso is almost parallel with the ground. Start with your upper arm in line with your torso and your elbow bent at 90 degrees, holding a dumbbell. Keeping your upper arm fixed, extend your elbow until your arm is straight and the weight is directly behind you. Pause briefly at the top, then return with control.
Use light to moderate weights and focus on a strong squeeze at the end of each rep so that you feel your triceps doing the work, not your shoulder.
Dumbbell JM press
The dumbbell JM press blends a press and an extension, and it is excellent for training tricep power. The key is that your elbows initiate the motion. This lets you accelerate the weight and then push through with the triceps without too much deceleration at the top.
Lie on a bench holding dumbbells like you would for a close grip press. Bend your elbows and slightly move the dumbbells toward your face, not straight down to your chest. Your upper arms will stay at about a 45 degree angle to your torso. Once you reach a comfortable bottom position with tension on your triceps, drive the weights back up quickly but under control.
Use moderate weights and low to medium reps so you can focus on speed and crisp lockout, which helps carry over to explosive pressing.
Dumbbell upright dip variation
If you do not have parallel bars or dip handles, you can simulate a dip pattern with a dumbbell upright dip. By keeping your torso upright, you emphasize elbow extension, which loads your triceps more.
You can strap a dumbbell with a strong dog leash or use a belt as a weight substitute to add load as you get stronger. Set your hands on sturdy surfaces such as benches or boxes, keep your body vertical, and bend your elbows to lower yourself until you feel a good stretch in the triceps. Press straight back up by focusing on driving through your hands and straightening your elbows.
Since you remain upright, your shoulders are less stressed compared to leaning forward, so more of the work shifts to the triceps.
Simple dumbbell tricep workout templates
You can organize these exercises into quick, focused workouts that fit into your week. Adjust the sets and reps based on your experience level and available time.
Strength focused tricep workout
Use this when you want to increase pressing power and load:
- Close grip dumbbell bench press: 4 sets of 6 to 8 reps
- Dumbbell JM press: 3 sets of 6 to 8 reps
- Dumbbell upright dip variation: 3 sets of 8 to 10 reps
Rest 90 to 120 seconds between sets. Choose weights that feel challenging but allow you to keep your elbows controlled on every rep.
Hypertrophy focused tricep workout
Use this when your goal is more muscle size and a strong pump:
- Lying dumbbell tricep extension: 4 sets of 10 to 12 reps
- Overhead dumbbell tricep extension: 3 sets of 10 to 12 reps
- Dumbbell triceps kickback: 3 sets of 12 to 15 reps
Rest 45 to 75 seconds between sets. Focus on stretching and squeezing the triceps on each repetition rather than just moving the weight.
At home minimal equipment workout
If you only have one or two dumbbells at home, you can still train your triceps effectively:
- Close grip push up on a single dumbbell: 3 sets of max reps
- Single arm overhead dumbbell tricep extension: 3 sets of 10 to 12 reps per arm
- Dumbbell triceps kickback: 3 sets of 12 to 15 reps per arm
For the close grip push up on a single dumbbell, place one dumbbell on the floor and grip it with both hands in a plank position. Lower your chest toward the dumbbell to get a deep stretch in your triceps, then push back up powerfully.
Form tips and recovery guidelines
Good form keeps your tricep workouts effective and protects your joints. A few simple habits make a big difference.
Keep your elbows under control. Letting them flare out too far often shifts tension away from the triceps and puts more strain on your shoulders. Aim to feel your elbows moving like a hinge while your upper arm stays relatively stable.
Avoid jerking the weights, especially on extension movements. Smooth and steady motion, as highlighted in the Mayo Clinic guidance on dumbbell triceps extensions, ensures the triceps are doing the work and reduces your risk of injury.
Also pay attention to recovery. Training triceps right after a heavy chest or shoulder session can lead to overuse and poor progress. Give yourself at least 24 hours between intense upper body sessions that involve tricep work so the muscles can repair and grow.
How to progress your dumbbell tricep training
To keep seeing results from your dumbbell tricep workouts, you need progressive overload, which means gradually making the work harder over time.
You can do this in several ways:
- Increase the weight of your dumbbells when you can hit the top of your rep range with solid form.
- Add one more set for a key exercise once your current workload feels manageable.
- Slow down the lowering phase of each rep to increase time under tension.
- Shorten rest periods slightly to increase the challenge, especially in hypertrophy focused sessions.
Rotate exercises every few weeks but keep at least one heavy press and one extension in your routine. This combination trains both strength and specific tricep development.
Putting it all together
If you want stronger and more defined arms, dumbbell tricep workouts give you a flexible, accessible way to train. By learning a handful of effective exercises, focusing on controlled form, and progressing gradually, you can build triceps that support heavier presses and look impressive from every angle.
Start by choosing one of the workout templates above and perform it twice per week, leaving at least a day between sessions. As you become more comfortable, adjust weights, reps, and exercise selection to match your goals.
With consistent effort and smart progression, a simple pair of dumbbells is enough to sculpt powerful triceps at home or in the gym.
