Build Bigger Arms: The Best Dumbbell Tricep Exercises for Strength and Mass

When people think of building bigger arms, they often default to biceps. But if you truly want arm size and definition, training your triceps is essential—after all, they make up nearly two-thirds of your upper arm. And when it comes to effective, accessible training, dumbbells are an unbeatable tool. Whether you're at home or in the gym, these best tricep exercises with dumbbells will help you develop strength, size, and control.

Why Train Triceps with Dumbbells?

Dumbbells allow for a greater range of motion, reduce joint stress, and help correct muscular imbalances. You’re not locked into a fixed path like with machines or even some barbell movements, making dumbbell tricep workouts safer and more joint-friendly.

Best Dumbbell Tricep Exercises

These exercises target all three heads of the triceps (long, lateral, and medial), ensuring well-rounded development.

1. Dumbbell Overhead Tricep Extension (Two-Handed)

A staple for building the long head of the triceps.

• Sit or stand tall, holding one dumbbell with both hands overhead.

• Lower the weight behind your head by bending the elbows, keeping your upper arms still.

• Extend your arms back up, squeezing your triceps.

Pro Tip: Keep elbows tight to prevent shoulders from taking over.

2. Single-Arm Overhead Tricep Extension

Great for isolating each side and correcting strength imbalances.

• Hold a dumbbell in one hand and extend your arm straight overhead.

• Lower it behind your head and then extend back up.

This one hits deep and is especially effective for hypertrophy when performed slowly.

3. Dumbbell Kickbacks

An underrated gem for targeting the lateral head.

• Hinge at the hips, keeping a flat back and elbows bent at 90 degrees.

• Extend your arms fully behind you, then return to the starting position.

• Keep the movement strict and controlled.

Personal Note: I used to rush this one early on, thinking heavier was better. But slowing down and focusing on form changed everything. Once I started locking out and pausing at the top, the burn in my triceps became unreal—and so did the results.

4. Dumbbell Floor Press with Neutral Grip

Often overlooked, this builds pressing power and triceps thickness.

• Lie on the floor with dumbbells in each hand, palms facing each other.

• Lower the dumbbells until your triceps touch the floor, then press back up.

This is a joint-friendly alternative to the close-grip bench press.

5. Dumbbell Tate Press

Targets all three tricep heads with a unique angle.

• Lie on a bench holding two dumbbells over your chest.

• Bend your elbows outward, bringing the dumbbells toward your chest.

• Press back up in the same path.

6. Dumbbell Skull Crushers (Lying Tricep Extensions)

Perfect for tricep mass.

• Lie flat on a bench holding two dumbbells directly above your chest.

• Slowly bend your elbows, lowering the dumbbells beside your head.

• Extend your arms back to the start.

Make sure your elbows stay pointed toward the ceiling the entire time.

---

7. Close-Grip Dumbbell Press

Think of it as a dumbbell version of the close-grip bench press, but easier on your wrists.

• Lie flat on a bench, dumbbells in each hand with palms facing in.

• Keep the dumbbells close together and press straight up, emphasizing the triceps.
