Dumbbell Seated Triceps Extension
How to Perform - Dumbbell Seated Triceps Extension
- Sit on a bench with your back straight, feet firmly planted on the floor, and grab a single dumbbell with both hands, cupping the upper end of the weight.
- Raise the dumbbell overhead with arms fully extended and palms facing the ceiling, keeping your elbows pointed forward.
- Inhale as you slowly lower the weight behind your head by bending at the elbows while keeping your upper arms stationary and close to your ears.
- Control the descent until your forearms reach just below parallel to the floor or until you feel a stretch in your triceps.
- Maintain a neutral wrist position throughout the movement and keep your core engaged to prevent arching your lower back.
- Exhale as you extend your elbows to raise the dumbbell back to the starting position, focusing on contracting your triceps.
- Keep your shoulders down and relaxed throughout the exercise, avoiding the tendency to shrug them toward your ears.
- Repeat for the desired number of repetitions, maintaining control of the weight without using momentum.
Important information
- Keep your elbows pointed forward and as close to your head as possible to maximize triceps engagement and minimize shoulder strain.
- If you experience any elbow pain, try using a lighter weight or adjusting your grip width on the dumbbell.
- Maintain a slight bend in your elbows at the top position to keep tension on the triceps and protect your elbow joints.
- For better stability, press your lower back into the bench and avoid leaning forward during the movement.

The Dumbbell Seated Triceps Extension stands as a cornerstone exercise for anyone looking to develop impressive triceps definition and strength. This intermediate-level movement specifically targets the triceps brachii—the three-headed muscle that runs along the back of your upper arm—providing an effective isolation that's difficult to achieve with compound movements alone.
When incorporated into a bodybuilding regimen, this exercise allows for precise muscle targeting and the kind of controlled tension that stimulates optimal growth. The seated position creates a stable platform that lets you focus entirely on proper form and muscle engagement without compensating with other body parts, making it particularly valuable during recovery phases when stability is paramount.
What makes this movement particularly effective is how it works all three heads of the triceps muscle, with special emphasis on the long head. This comprehensive targeting is essential for balanced development and that coveted horseshoe appearance at the back of the arm that many fitness enthusiasts strive for. The controlled nature of the seated position also makes this exercise remarkably joint-friendly compared to some more explosive triceps movements.
From a strength development perspective, the Dumbbell Seated Triceps Extension offers progressive overload potential that translates well to improved performance in pressing movements like bench press and shoulder press. The isolated nature helps identify and overcome triceps weaknesses that might be limiting your compound lift numbers.
Whether you're looking to add definition to your arms for aesthetic purposes or build functional pushing strength, this exercise delivers remarkable results when performed consistently. The beauty of this movement lies in its versatility—it can be performed with a single dumbbell held with both hands for greater weight, or with lighter dumbbells in each hand for more stabilization work and balanced development. Either approach will contribute significantly to both your physique goals and overall upper body strength.
FAQ - Dumbbell Seated Triceps Extension
This exercise primarily targets all three heads of the triceps brachii, with particular emphasis on the long head that runs along the back of your upper arm. The controlled nature of the movement creates optimal tension for muscle growth and definition.
Stand facing the cable machine with the ankle attachment secured, maintain a slight bend in your supporting leg, and keep your core engaged throughout the movement. Focus on driving the movement from your glutes rather than your lower back, and avoid arching or rounding your spine.
For optimal results, perform this exercise 1-2 times weekly with 48-72 hours of recovery between triceps-focused workouts. Include 3-4 sets of 8-12 repetitions, adjusting the weight to ensure the last few reps of each set are challenging but doable with proper form.
Yes, using a single dumbbell held with both hands allows for heavier loading and greater overall tension on the triceps. Alternatively, using individual dumbbells in each hand helps address strength imbalances and requires more stabilization, making it ideal for balanced development or rehabilitation purposes.
Avoid flaring your elbows outward, which shifts tension away from the triceps and puts stress on the shoulders. Don't use momentum by rocking your torso, as this reduces effectiveness and increases injury risk. Finally, don't overextend at the top of the movement by locking out your elbows, which can cause joint strain.
