7 Dumbbell Workouts to Grow Your Triceps Fast

7 Dumbbell Workouts to Grow Your Triceps Fast: If you’re chasing arms that turn heads and perform like champions, it’s time to give your triceps the attention they deserve. These three-headed powerhouses make up two-thirds of your upper arm size—and training them properly can transform not just your aesthetics but also your functional strength.

From locking out heavier bench presses to stabilizing your shoulders during sports, strong triceps are non-negotiable for performance and physique.

Why Train All Three Tricep Heads?

“Balanced tricep development isn’t just about looking good—it’s about moving better,” says certified strength coach Mike Reynolds. “The lateral head gives you that ‘horseshoe’ shape everyone wants, the long head supports shoulder stability, and the medial head ties everything together for explosive power.”

By hitting all three heads with a mix of isolation and compound movements, you’ll maximize hypertrophy (muscle growth), improve joint health, and enhance overall athleticism. Now let’s get to work!

1. Kickbacks – Isolate and Annihilate

Targets: Lateral Head

• How to Do It: Hold a dumbbell in each hand and hinge at your hips until your torso is nearly parallel to the floor. Bend your elbows to 90 degrees, then extend your forearms backward until your arms are fully straight. Squeeze your triceps hard at the top before lowering slowly.
• Tips for Engagement: Keep your upper arms locked in place—don’t let them sway. Focus on controlled, deliberate reps rather than momentum.
• Why It Rocks: Kickbacks isolate the lateral head, carving out that coveted horseshoe definition. They’re perfect for finishing off a brutal arm session.
• Sets/Reps: 3–4 sets of 12–15 reps per arm.

2. Overhead Extensions – Hit the Long Head Hard

Targets: Long Head

• How to Do It: Sit on a bench or stand with feet shoulder-width apart. Hold a single dumbbell with both hands and press it overhead. Lower the weight behind your head by bending your elbows, keeping them close to your ears. Extend your arms back to the starting position.
• Tips for Engagement: Avoid flaring your elbows outward—keep them tucked to maximize tension on the long head. Control the descent for maximum stretch.
• Why It Rocks: This move stretches and contracts the long head through its full range of motion, promoting size and flexibility.
• Sets/Reps: 3–4 sets of 10–12 reps.

3. Close-Grip Presses – Pack on Mass

Targets: All Three Heads

• How to Do It: Lie flat on a bench with a dumbbell in each hand. Position your hands close together, palms facing inward. Lower the weights toward your chest, keeping your elbows tight to your sides. Press the dumbbells back up explosively.
• Tips for Engagement: Think about driving your elbows down and back as you press to keep tension on the triceps instead of shifting it to your chest.
• Why It Rocks: Close-grip presses are a heavy hitter for building mass and strength across all three heads. Plus, they translate directly to improved lockout power in other lifts like the bench press.
• Sets/Reps: 4 sets of 8–10 reps.

4. Skull Crushers – Crush Plateaus

Targets: Medial & Long Heads

• How to Do It: Lie on a bench with a dumbbell in each hand, arms extended above your chest. Bend your elbows to lower the weights toward your forehead, stopping when your forearms are parallel to the ground. Extend your arms back to the starting position.
• Tips for Engagement: Keep your elbows stationary—only your forearms should move. Use a slight incline on the bench if you feel discomfort in your elbows.
• Why It Rocks: Skull crushers deliver constant tension to the triceps, making them ideal for breaking through stubborn plateaus.
• Sets/Reps: 3–4 sets of 10–12 reps.

5. Neutral-Grip Presses – Finish Strong

Targets: Inner Triceps

• How to Do It: Lie on a bench holding dumbbells with a neutral grip (palms facing each other). Start with the weights at chest level, then press them upward until your arms are fully extended. Lower under control and repeat.
• Tips for Engagement: Focus on squeezing your triceps at the top of each rep. The neutral grip reduces shoulder strain while emphasizing the inner triceps.
• Why It Rocks: This variation minimizes joint stress while maximizing contraction, making it perfect for high-rep burnouts.
• Sets/Reps: 3 sets of 12–15 reps.

Bonus Move: Dumbbell Dips – Add Depth

While technically a bodyweight exercise, adding dumbbells to your lap increases resistance for insane tricep activation.

• How to Do It: Place your hands on parallel bars or a sturdy surface, hold a dumbbell between your thighs, and lower yourself until your elbows reach 90 degrees. Push back up forcefully.
• Why It Rocks: Dips torch the triceps and mimic real-world pushing motions, enhancing functional strength.
• Sets/Reps: 3 sets of 8–10 reps.
