Decline Dumbbell Triceps Extension
Decline Dumbbell Triceps Extension is a beginner-level isolation in the strength category that primarily works the triceps. It is performed with dumbbells.
How to do it
- 1Secure your legs at the end of the decline bench and lie down with a dumbbell on each hand on top of your thighs. The palms of your hand will be facing each other.
- 2Once you are laying down, move the dumbbells in front of you at shoulder width. The palms of the hands should be facing each other and the arms should be perpendicular to the floor and fully extended. This will be your starting position.
- 3As you breathe in and you keep the upper arms stationary (and elbows in), bring the dumbbells down slowly by moving your forearms in a semicircular motion towards you until your thumbs are next to your ears. Breathe in as you perform this portion of the movement.
- 4Lift the dumbbells back to the starting position by contracting the triceps and exhaling.
- 5Repeat for the recommended amount of repetitions.

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.
