Performing the: A Step-by-Step Tutorial Dumbbell Lying One Arm Pronated Triceps Extension
Keep your elbow stationary and close to your head as you slowly lower the dumbbell in an arc motion behind your head until your forearm is parallel to the floor.
Pause for a moment, then reverse the motion by extending your arm back to the starting position without moving your elbow.
Ensure that the movement is controlled and that the focus is on the contraction of the triceps muscle.
Repeat the desired number of repetitions and then switch to the other arm.
