Performing the: A Step-by-Step Tutorial Dumbbell Lying Triceps Extension
Keep your upper arms stationary throughout the exercise, only moving your forearms to lower the weights in a controlled manner until they are beside your head, elbows at about a 90-degree angle.
Make sure to keep your elbows close to your head and perpendicular to the floor during this movement.
After a brief pause at the bottom of the movement, use your triceps to return the weight to the starting position, fully extending your arms but not locking your elbows.
Repeat this motion for your desired number of repetitions, ensuring to maintain form and control throughout the exercise.
