Dumbbell One Arm Triceps Extension

What is Dumbbell One-Arm Triceps Extension? The dumbbell one-arm triceps extension is a strength training exercise that targets the triceps muscles in the back of the upper arm. It is an effective isolation exercise that helps in building muscle mass and strength in the triceps.

Tutorial

1. Starting Position:

• Stand or sit on a bench with your back straight and core engaged.

• Hold a dumbbell in one hand with an overhand grip and extend your arm overhead, keeping it perpendicular to the floor. 2. Execution: - Slowly lower the dumbbell behind your head while keeping your upper arm stationary and close to your head.

• Extend your elbow to raise the dumbbell back to the starting position, fully contracting the triceps at the top of the movement. - Repeat for the desired number of repetitions on one arm before switching to the other arm.

Common Mistakes

• Using momentum: Avoid swinging the dumbbell to lift the weight as it reduces the effectiveness of the exercise.

• Not keeping the elbow stable: Ensure your upper arm remains stationary throughout the movement to isolate the triceps. - Using excessive weight: Using a weight that is too heavy can compromise form and lead to injury.

Tips for Better Results

• Focus on the mind-muscle connection to fully engage the triceps during the movement. - Control the eccentric (lowering) phase of the exercise to maximize muscle activation.

• Choose a weight that allows you to perform the exercise with proper form for the desired number of repetitions.

Muscles Worked The dumbbell one-arm triceps extension primarily targets the triceps brachii muscle, specifically the long head. Additionally, it also engages the lateral and medial heads of the triceps to a lesser extent.
