    How to perform it
    1. Sit down at the end of a flat bench with a dumbbell in both arms using a neutral grip (palms of the hand facing you).
    2. 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.
    3. The upper arms with the dumbbells should be close to the torso and aligned with it (lifted up until they are parallel to the floor while the forearms are pointing towards the floor as the hands hold the weights). Tip: There should be a 90-degree angle between the forearms and the upper arm. This is your starting position.
    4. Keeping the upper arms stationary, use the triceps to lift the weight 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.
    5. After a second contraction at the top, slowly lower the dumbbells back to the starting position as you inhale.
    6. Repeat the movement for the prescribed amount of repetitions.

    Sets and reps: 3 sets of 10 to 15 reps.

Why You Might Need a Dumbbell Seated Bench Extension Alternative

You may substitute the Dumbbell Seated Bench Extension for several practical reasons: shoulder pain with overhead position, limited dumbbell load, dislike of seated isolation, or a need for greater progressive overload. The exercise primarily produces elbow extension, stressing the triceps long head when the arm is overhead and the lateral/medial heads when elbows stay by the ribs. Swapping changes moment arm and torque at the elbow and shoulder; for example, skull crushers shift load to a supine plane and reduce shoulder elevation. When selecting a substitute, assess which triceps head you want to target and whether you need more stability (bench-supported) or more range (overhead). Technique cue: limit scapular shrug and move only at the elbow joint.

Dumbbell Seated Bench Extension FAQ

What muscles does Dumbbell Seated Bench Extension work?

The move primarily targets the triceps brachii, long, lateral and medial heads, with the long head emphasized when the arm is overhead. Secondary stabilizers include the anterior deltoid and scapular stabilizers; keep the scapula packed and extend only at the elbow to maximize triceps activation.
