How to do it
Execution:
  1. 1
    Sit on a bench and raise a dumbbell overhead with one hand.
  2. 2
    Keep the elbow pointing up and stable.
  3. 3
    Bend the elbow to lower the dumbbell behind your head.
  4. 4
    Fully extend the arm.
Tip: pressing your back against the bench prevents torso lean — 100% triceps isolation.
