The dumbbell skull crusher is a highly effective exercise for isolating the triceps brachii, the large muscle on the back of the upper arm responsible for elbow extension. This exercise specifically targets all three heads of the triceps: the long head, lateral head, and medial head, helping you develop strength and definition. • The #triceps brachii is innervated by the radial nerve, which originates from the C6 to C8 #spinal roots. These nerves transmit signals from the spinal cord to the #triceps, allowing for smooth and controlled extension of the arm during the skull crusher. By consistently performing this exercise, you’ll improve your triceps strength, while also enhancing the neuromuscular coordination between the muscle and its spinal connections
