One Arm Dumbbell Triceps Extension

I read a Frederic Delavier’s book « Strength Training Anatomy » and there is good stuff.

Standing or sitting with a dumbbell in a hand and your arm in a vertical position :

  • Inhale and flex your arm to bring the dumbbell behind your neck.

  • Back to the start position and exhale at the end of the movement.

The vertical position of the arm stretches the long head of the triceps to have a good contraction during work.

Note : It’s important to squeeze your abs to avoid over-arching your back.
