How To Do Dumbbell Lying Triceps Extension Properly

Few other exercises promise great results on the triceps like the dumbbell lying triceps extension.

Many people pay more attention to biceps when it comes to sculpting more muscular arms.

This may be attributed to the fact that whenever you flex your elbow, they are the arm muscles that are primarily seen. However, biceps only make up a third of the mass of your upper arms.

Triceps make up the other two-thirds. Triceps are the posterior muscles of the upper arm and also form a powerful extensor for the elbow joint.

Tricep extensions are perfect for building and shaping these arm muscles.  The dumbbell lying triceps extension particularly target these triceps more effectively.

This is because it equally works all the three heads of the triceps brachii; medial, lateral, and long head.

Dumbbell lying triceps extension only requires a flat bench and a pair of dumbbells. It is also called the skull crusher because you could put your skull at risk if you do not perform it correctly.

It is important to add this exercise to your upper-body muscle-building workout because stronger arms make you stronger and more functional in your everyday tasks.

WHAT MUSCLES DO DUMBELL LYING TRICEPS EXTENSION

The dumbbell lying triceps extension is an isolation exercise meaning it trains just one muscle group across a single joint.

TRICEPS BRACHII MUSCLE

The dumbbell lying triceps extension trains the triceps brachii muscle. The triceps brachii muscle is located in the rear of your upper arm.

It consists of three heads — the long head, lateral head and medial head which insert into the elbow. The long head and lateral head originate from the scapula and back of the humerus respectively and stretches across the elbow joint.

During the exercise when the tricep contracts, it extends the elbow joint against the resistance of the weight and gravity.

However, more emphasis is given to the long head of the triceps because the necessary shoulder movement leads to combination of shoulder and elbow extension.

The secondary muscles worked are the chest, deltoid, forearm and anconeus while the antagonists are biceps brachii, brachialis and brachioradialis.
