Weighted Seated Triceps Extension
Weighted Seated Triceps Extension Exercise Description
The Weighted Seated Triceps Extension is an overhead elbow‑extension exercise that primarily targets the triceps brachii (long, lateral, and medial heads), with the overhead position placing greater demand on the long head. Sitting provides lower‑body stability so you can focus on precise elbow motion while keeping the torso steady. Proper form keeps the upper arms close to the head, elbows pointing forward, and the spine neutral to avoid compensations such as rib flare or excessive lumbar arching. Wrists remain straight and the shoulders stay quiet—allowing natural upward rotation overhead without shrugging. This exercise is commonly performed with a single dumbbell held with both hands, but the same mechanics apply if using a weight plate or similar implement.

How To Do The Weighted Seated Triceps Extension Exercise
‘- Sit tall on a flat or back‑supported bench with feet flat and ribs stacked over pelvis (neutral spine).
– Grip one end of a dumbbell with both hands, palms facing up around the top plate; press it overhead until elbows are straight but not locked.
– Set shoulders gently down; keep upper arms close to your ears and as vertical as comfortable.
– Brace your trunk and keep wrists neutral (no bending back).
– Hinge only at the elbows to lower the dumbbell behind your head in a controlled path; stop at a comfortable stretch without moving the upper arms.
– Keep elbows pointing forward; avoid flaring them wide or letting shoulders shrug.
– Extend the elbows to return the weight overhead, finishing with straight—but not forcefully locked—elbows.
– Maintain a steady head and neck position (chin slightly tucked) and avoid arching the low back or letting ribs lift.
– To finish safely, lower the weight to the upper chest or lap before setting it down.

Weighted Seated Triceps Extension Beginner Introduction
The Weighted Seated Triceps Extension is a seated overhead arm exercise that centers on the backs of the upper arms. With the lifter seated on a flat or supported bench, the lower body serves mainly as a base so attention stays on bending and straightening the elbows. Because the weight is positioned overhead, the portion of the triceps that crosses the shoulder is especially challenged, while the upright posture encourages a steady, quiet torso.
In most cases, a dumbbell or similar weight is held between both hands above the head, with the arms roughly alongside the ears. The movement then revolves around smoothly lowering and lifting the weight by hinging at the elbows while the upper arms stay mostly in place. Wrist alignment, calm shoulders, and a stable head and neck position contribute to smooth motion overhead and help the spine stay naturally stacked rather than excessively arched. This creates a focused arm‑extension pattern that emphasizes control, alignment, and consistent tension through the triceps from start to finish.
