How to perform Decline Dumbbell Triceps Extension
- Secure 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.
- Once 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.
- As 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.
- Lift the dumbbells back to the starting position by contracting the triceps and exhaling.
- Repeat for the recommended amount of repetitions.
Muscles worked
- Triceps (primary): straightens the elbow to lock out every press and pushdown.
Sets & reps by goal
| Goal | Sets × reps | Load | Rest |
|---|---|---|---|
| Strength | 3–5 × 3–5 | Heavy (~85%+) | 2–3 min |
| Hypertrophy | 3–4 × 8–12 | Moderate (~65–75%) | 60–90 s |
| Endurance | 2–3 × 15–20 | Lighter (~50–60%) | 30–45 s |
Pick the row that matches your goal. If you're newer, anchor in the hypertrophy range while you groove the form.
Form tips
- Fix the elbows in place and let only the forearms move, keeping the load on the triceps.
- Each side works on its own, so match the depth and speed of both arms and don't let the stronger side take over.
- Treat every rep the same — a repeatable setup and bar path is what lets you add weight safely over time.
- Breathe out on the effort and in on the return, keeping one steady rhythm across the set.
Common mistakes
- Letting the elbows flare and drift forward so the shoulders quietly take over.
- Letting the dumbbells drift apart or clang together at the top instead of controlling the path.
- Chasing weight jumps before the current load feels solid on every rep.
