Performing the: A Step-by-Step Tutorial Dumbbell Seated Triceps Extension
The palms of your hands should be facing upward and your elbows should be close to your head. This will be your starting position.
Slowly lower the dumbbell behind your head while keeping your upper arms still, only bending your elbows until they are at a 90-degree angle.
Pause for a moment at the bottom of the movement, then use your triceps to return the dumbbell back to the starting position.
Repeat the movement for your desired amount of repetitions, ensuring to keep your elbows in close to your head throughout the exercise to maximise the effectiveness.
