Most people focus almost entirely on biceps and then wonder why their arms do not look bigger overall. Triceps make up roughly two-thirds of the upper arm and neglecting them is exactly why so many arm routines fall short. These exercises hit all three heads of the tricep and actually produce the size and definition most people are chasing.
Close Grip Bench Press

Hands placed closer together on the bar shifts most of the load directly onto the triceps. Heavy compound movement that allows real progressive overload over time and builds serious mass in the overall upper arm.
Skull Crusher

Lying flat, barbell or EZ bar lowered toward the forehead with elbows locked in place. Isolates the tricep almost completely and the stretch at the bottom of the movement hits the long head in a way most exercises never reach.
Tricep Dip

Bodyweight or weighted, dips load the triceps through a full range of motion with serious tension throughout. One of the oldest upper body exercises around and still one of the most effective for adding real thickness to the back of the arm.
Cable Pushdown

Rope or straight bar attachment, elbows locked at the sides, pushing straight down until arms are fully extended. Constant cable tension keeps the muscle loaded through the whole movement in a way free weights simply cannot replicate.
Overhead Tricep Extension

Arms extended overhead, weight lowered behind the head and pressed back up. Stretches the long head of the tricep under load which is one of the better ways to build that thick horseshoe shape most people are actually after.
Single Arm Cable Extension

Same idea as the pushdown but one arm at a time. Removes any dominant side compensation and forces each tricep to do its own work independently. Good for fixing imbalances that build up quietly over time.
Diamond Push Up

Hands forming a diamond shape directly under the chest, elbows tucking in close to the body on the way down. Bodyweight movement that can be done anywhere and genuinely challenges the triceps without any equipment at all.
Tricep Kickback

Bent over with upper arm parallel to the floor, extending the forearm back until the arm is fully straight. Not a heavy movement but excellent for the final contraction and works well as a finishing exercise at the end of a session.
Board Press

Barbell press with a board placed on the chest that reduces the range of motion and keeps the load in the portion of the lift where triceps do the most work. Common in powerlifting and genuinely effective for overloading the tricep with heavier weight.
Tate Press

Dumbbells held above the chest with elbows flared out, lowering them toward the chest and pressing back up. Unusual movement that most people have never tried and one that hits the tricep from a completely different angle than standard pressing or extension work.
