How to do the Dumbbell Seated Overhead Triceps Extension
Sit down on a bench with back support and grasp a dumbbell with both hands and hold it overhead at arm's length. Tip: a better way is to have somebody hand it to you especially if it is very heavy. The resistance should be resting in the palms of your hands with your thumbs around it. The palm of the hand should be facing inward. This will be your starting position.
Keeping your upper arms close to your head (elbows in) and perpendicular to the floor, lower the resistance in a semi-circular motion behind your head until your forearms touch your biceps. Tip: The upper arms should remain stationary and only the forearms should move. Breathe in as you perform this step.
Go back to the starting position by using the triceps to raise the dumbbell. Breathe out as you perform this step.
Repeat for the recommended amount of repetitions.
Sets and reps
| Goal | Sets | Reps | Rest |
|---|---|---|---|
| Muscle growth | 2–4 | 10–15 | 1 min |
| Muscular endurance | 2–3 | 15–25 | 45 s |
When you hit the top of the rep range on every set, add 2 kg (5 lb) next session and work back up.
Starting points from training research. Stop each set 1–3 reps short of failure.
Muscles worked
Primary
Two-thirds of your upper arm. The triceps straighten the elbow; overhead extensions stretch the long head, pushdowns and close presses load the rest.
Train smarter
- 2 day workout plan: build muscle training twice a weekA 2 day workout plan that still builds muscle and strength: two full-body sessions, sets and reps, supersets to save time and what results to expect.
- 30 minute gym workout: templates that build muscleA 30 minute gym workout can build real muscle. Supersets, smart exercise choice and three ready-to-use templates for 30 to 45 minute sessions.
- 4 day workout split: best options and a full programWhich 4 day workout split is best? Upper/lower, full body, torso/limbs and bro splits compared in brief, then a complete 4-day program with sets and reps.
