If you want bigger, stronger arms, your triceps need to be front and center in your training routine. While biceps get most of the attention, the triceps muscles make up nearly two-thirds of your upper arm. And the best part? You don’t need a gym or fancy equipment to grow them.
This guide will walk you through the most effective dumbbell triceps exercises at home—perfect for anyone training in a small space with limited gear. All you need is a dumbbell in each hand, basic form knowledge, and consistency.
Why Tricep Training Matters
The triceps are composed of three heads:
- Long head
- Lateral head
- Medial head
Each head must be activated through different angles and movement patterns to maximize growth. Neglecting any one head can lead to weak points, lack of definition, and imbalanced arms.
By focusing on dumbbell tricep exercises, you can isolate these muscles effectively and safely—even without a gym. Dumbbells provide a better range of motion, more control, and flexibility in arm positioning compared to fixed machines.
Benefits of Dumbbell Tricep Workouts at Home
- Convenience: Train anytime, anywhere without waiting for equipment
- Efficiency: Target all three tricep heads with simple but powerful moves
- Upper body strength: Tricep development improves pushing strength for push-ups, presses, and more
- Joint-friendly: Dumbbells allow natural movement, reducing strain on the shoulders and elbows
- Perfect for all levels: Whether you’re a beginner or advanced, dumbbells let you scale intensity
Now let’s break down the most effective exercises.
1. Overhead Tricep Extension
One of the best isolation exercises for the long head, this move stretches and activates the triceps throughout the entire range of motion.
How to:
- Stand upright with knees slightly bent, feet at hips width
- Hold a dumbbell with both hands, raise it overhead
- Keep your elbows bent and close to your ears
- Lower the weight behind your head to a 90-degree angle, then extend fully
Pro Tips:
- Keep your upper arm stationary
- Focus on bringing the dumbbells up with control
2. Tricep Kickbacks
Tricep kickbacks are excellent for targeting the lateral and medial head, especially when performed slowly and with strict form.
How to:
- Get into a hinge position with a flat back, knees slightly bent
- Start with a dumbbell in each hand, elbows tucked close
- Extend your arms behind you until fully straight, then return to the starting position
Pro Tips:
- Keep elbows locked in place
- Don’t swing your torso or use momentum
3. Lying Dumbbell Skull Crushers
This variation improves mind-muscle connection and keeps tension on the triceps muscles through a full range of motion.
How to:
- Lie flat on a mat or bench
- Hold a dumbbell in each hand above your chest
- Slowly bend the elbows to lower weights toward your head
- Stop at a 90-degree angle, then press back to the top
4. Close-Grip Dumbbell Press
Simulates the close-grip bench press and places heavy emphasis on working the triceps while also activating the chest and shoulders.
How to:
- Lie on your back with dumbbells over your chest, pressed together
- Keep elbows close to your sides
- Lower the weights and press back up, keeping tension on the triceps
5. One-Arm Overhead Dumbbell Extension
This unilateral variation fixes imbalances and adds focused overload to the long head.
How to:
- Stand upright, hold a dumbbell in one hand overhead
- Lower it behind your head, keeping your elbow bent
- Push back up, maintaining tension through the upper arm
6. Dumbbell Floor Press
A compound movement that hits both the triceps and chest, the floor press limits excessive stretch and protects your shoulders.
How to:
- Lie on the floor, dumbbells in each hand, elbows on the ground
- Press the weights upward, squeezing the triceps at the top
- Lower slowly to maintain control
7. Plank Dumbbell Row + Kickback (Advanced)
Combine a plank position hold with a tricep movement for maximum challenge.
How to:
- Get into a high plank position with dumbbells under your hands
- Row one dumbbell to your waist, then extend your arm back into a kickback
- Return to floor and switch sides
This combo improves stability, core strength, and upper body strength while still working the triceps hard.
Sample Tricep Workout at Home
Here’s a complete dumbbell tricep workout you can do in just 30 to 40 minutes. It’s designed to target all three heads of the triceps—long head, lateral head, and medial head—through a mix of overhead, pressing, and isolation movements. Start with overhead tricep extensions to stretch and engage the long head, followed by tricep kickbacks for lateral and medial activation. Then move into lying skull crushers to overload the entire muscle. Close-grip dumbbell presses and one-arm overhead extensions further isolate each arm and strengthen pressing power. Add in dumbbell floor presses to build upper body strength, and finish with plank row to kickback combinations for an advanced core and tricep challenge. Perform 3 to 4 sets of each exercise with 10 to 15 reps per set. Rest 45 to 60 seconds between sets. You can run this routine 2 to 3 times per week, depending on your recovery and training split. Stick with it, and you’ll notice stronger arms, better definition, and more control in all upper body lifts.
Tips to Maximize Your Gains
1. Slow the Eccentric
Controlling the descent—especially to a 90-degree angle—increases time under tension and promotes more growth.
2. Progressive Overload
Gradually increase weight, reps, or sets over time. Even small jumps make a big difference.
3. Form is Everything
Keep elbows stable, upper arm locked in place, and avoid swinging. Focus on precision.
4. Don’t Overtrain
Triceps assist in most pressing movements. Give them 48 hours between intense sessions.
