Instructions

1

Sit upright on a flat bench with feet firmly planted on the floor, back against the pad for support. Hold a dumbbell with both hands, gripping it vertically with palms facing up and the top plate resting in your palms.

2

Position the dumbbell directly above your head with elbows bent at approximately 90 degrees, keeping elbows shoulder-width apart and tucked close to the sides of your head. Ensure core is engaged and lower back maintains natural curve.

3

Slowly lower the dumbbell in a controlled manner by flexing the elbows, bringing the weight down behind your head toward the nape of the neck. Maintain elbow position and keep elbows stationary throughout the movement, allowing only the forearms to move.

4

Extend the elbows by pressing through the triceps to return the dumbbell to the starting position above your head. Fully extend without locking out elbows at the top. This completes one repetition.

Overview

Focusing on the Dumbbell Seated Bench Extension allows you to target the Triceps Brachii with precision. As a foundational Strength exercise, the integration of Dumbbell provides the necessary tension to trigger hypertrophy, while avoiding excessive joint strain.

Benefits

Improves overall Upper Arms stability and proprioception during heavy loads.
Acts as a highly scalable Strength movement, perfect for both beginners and elite athletes.
Reduces the likelihood of Upper Arms injuries by reinforcing connective tissue strength.
Allows for a natural movement path that closely mimics functional daily activities.

Common Mistakes

Rushing the repetition tempo instead of focusing on the mind-muscle connection with the Upper Arms.
Shrugging the shoulders or compensating with secondary muscles rather than isolating the Triceps Brachii.
Using excessive momentum to swing the Dumbbell rather than controlling the eccentric phase.

Pro Tips

Keep your breathing rhythmic: exhale sharply on the concentric push/pull, and inhale smoothly on the way down.

Muscle Anatomy

The primary driver is the Triceps Brachii. However, the movement also recruits Anterior Deltoid, Pectoralis Major, Core Stabilizers to maintain control of the Dumbbell.
