Standing Bent-Over One-Arm Dumbbell Triceps Extension
Standing Bent-Over One-Arm Dumbbell Triceps Extension is a beginner-level isolation in the strength category that primarily works the triceps. It also recruits the shoulders. It is performed with dumbbells.
How to do it
- 1With a dumbbell in one hand and the palm facing your torso, 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.
- 2The upper arm should be close to the torso and parallel to the floor while the forearm is pointing towards the floor as the hand holds the weight. Tip: There should be a 90-degree angle between the forearm and the upper arm. This is your starting position.
- 3Keeping the upper arms stationary, use the triceps to lift the weights as you exhale until the forearms are parallel to the floor and the whole arm is extended. Like many other arm exercises, only the forearm moves.
- 4After a second contraction at the top, slowly lower the dumbbell back to the starting position as you inhale.
- 5Repeat the movement for the prescribed amount of repetitions.
- 6Switch arms and repeat the exercise.

Tips and common mistakes
- •Focus on the muscle contraction and control the eccentric (lowering) phase.
- •Add load only once you complete all reps with good form — progressive overload.
- •Press through the full range and avoid snapping the joints into lockout.
- •Prioritize full range of motion over heavy weight with partial reps.
Sets and reps
For hypertrophy: 3–4 sets × 8–12 reps with 1–2 reps in reserve (RPE 7–9) and 1–2 minutes rest. For strength: 3–5 × 4–6 with longer rest.
