Original Exercise: Seated Bent-over One-arm Dumbbell Triceps Extension
How to Perform Seated Bent-over One-arm Dumbbell Triceps Extension
- Sit down at the end of a flat bench with a dumbbell in one arm using a neutral grip (palms of the hand facing you).
- Bend your knees slightly and bring your torso forward, by bending at the waist, while keeping the back straight until it is almost parallel to the floor. Make sure that you keep the head up.
- The upper arm with the dumbbell should be close to the torso and aligned with it (lifted up until it is parallel to the floor while the forearms are pointing towards the floor as the hands hold the weights). Tip: There should be a 90-degree angle between the forearms and the upper arm. This is your starting position.
- Keeping the upper arm stationary, use the triceps to lift the weight as you exhale until the forearm is parallel to the floor and the whole arm is extended. Like many other arm exercises, only the forearm moves.
- After a second contraction at the top, slowly lower the dumbbell back to the starting position as you inhale.
- Repeat the movement for the prescribed amount of repetitions.
- Switch arms and repeat the exercise.

Why You Might Need a Seated Bent-over One-arm Dumbbell Triceps Extension Alternative
You may substitute this exercise for several practical reasons: shoulder or elbow pain, lack of unilateral dumbbells, travel or gym limitations, or a preference for different load curves. The seated bent-over position biases the triceps with a fixed upper arm and a horizontal torso; alternatives can replicate elbow torque or change long-head stretch depending on your goal. For example, cable overhead extensions maintain constant tension and reduce joint shear—cue: keep ribs down and elbow pinned to the ear to maximize long-head activation. If you need a heavier load, use close-grip bench press and drive through the palms while keeping elbows close to the body to emphasize the lateral and medial heads.
How to Choose the Right Substitute
Select a substitute based on pain, equipment, and desired muscle emphasis. For elbow-friendly options choose cables or neutral-grip dumbbells to reduce valgus stress—cue: maintain a vertical forearm at full extension. If you want long-head stretch, pick overhead variations that place the shoulder in flexion. For maximum load and progressive overload use close-grip pressing patterns and ensure scapular stability by bracing the shoulder blades. Prioritize unilateral work when correcting imbalances; keep torso tight and elbow fixed to isolate the triceps effectively.
Frequently Asked Questions
What muscles does Seated Bent-over One-arm Dumbbell Triceps Extension work?
It primarily targets the triceps brachii—long, lateral, and medial heads—with the long head emphasized when the shoulder is flexed. Keep your upper arm stationary and hinge slightly at the torso; this isolates elbow extension and minimizes shoulder involvement.
What is the best bodyweight alternative to Seated Bent-over One-arm Dumbbell Triceps Extension?
Bench dips and triceps push-ups are the top bodyweight substitutes. For bench dips, cue a controlled descent and drive through the palms while keeping your elbows close to the sides to maximize elbow-extension torque and triceps activation.
Can I build muscle without doing Seated Bent-over One-arm Dumbbell Triceps Extension?
Yes. You can achieve hypertrophy with alternatives that provide progressive overload and full range of motion, such as close-grip bench press or cable overhead extensions. Focus on controlled eccentrics, full elbow extension, and gradually increasing load or volume to stimulate growth.
