The triceps make up roughly two-thirds of your upper arm. Yet most people spend the majority of their arm training on biceps. If you want arms that actually look developed — from the front, side, and back — the triceps muscle is where the real work happens.
This guide covers the best triceps muscle exercises, how the three heads of the triceps work, and how to structure a triceps workout that actually builds size and strength.
Understanding the Triceps Muscle
The triceps brachii has three heads — long, lateral, and medial — which is where the “tri” comes from. Each head attaches slightly differently and responds better to specific exercises and angles.
- Long head — runs along the back of the arm from the shoulder blade to the elbow. It is the largest head and the one most visible from behind. It is best targeted with overhead movements where the arm is raised above the head.
- Lateral head — on the outer side of the arm. This is the head that creates the horseshoe shape visible from the front. It responds well to pushdowns and close-grip pressing.
- Medial head — sits underneath the other two and is active in almost every triceps movement. It is the workhorse of the group.
For complete triceps development, you need movements that hit all three heads. Doing only pushdowns or only dips leaves significant muscle on the table.
The 8 Best Triceps Muscle Exercises
1. Close-grip bench press
Best for: Overall triceps mass, lateral and medial head
Equipment: Barbell, bench
The close-grip bench press is the single best mass-builder for triceps. It allows you to use heavy loads, which triggers the most muscle fiber recruitment. Grip the bar with hands about shoulder-width apart — not extremely narrow, which puts excess strain on the wrists.
Lower the bar to your lower chest, keep elbows tucked at roughly 45 degrees, and press back up. The movement feels similar to a regular bench press but you will feel the load shift noticeably toward the triceps.

2. Overhead tricep extension (dumbbell or cable)
Best for: Long head, the largest and most underdeveloped head in most people
Equipment: Dumbbell or cable machine
The long head of the triceps crosses the shoulder joint, which means it is only fully stretched when your arm is raised overhead. Most triceps exercises do not put the arm in this position — which is why the overhead extension is irreplaceable for complete development.
Sit or stand with one or two dumbbells held behind your head. Keep your elbows pointed forward, not flared. Lower the weight behind your head until you feel a stretch in the triceps, then extend back to the top. Control the descent — do not let the weight drop.
3. Skull crushers (EZ bar or dumbbell)
Best for: Long head and medial head, excellent for adding thickness
Equipment: EZ curl bar or dumbbells, bench
Lie on a flat bench with an EZ bar or dumbbells held directly over your chest. Keep your upper arms vertical and perpendicular to the floor — this is the key form point most people miss. Lower the bar toward your forehead (hence the name) by bending only at the elbows, then press back up.
If you experience elbow pain during skull crushers, try angling your upper arms slightly back toward your head rather than keeping them perfectly vertical. This small adjustment relieves pressure on the elbow joint.
4. Tricep dips
Best for: Lateral and medial head, great bodyweight option
Equipment: Parallel bars or two sturdy chairs
Dips are one of the most effective triceps exercises and require no equipment beyond a pair of parallel bars. The key is staying upright — lean forward and dips become a chest exercise. Keep your torso as vertical as possible and your elbows tracking close to your body.
Lower until your upper arms are parallel to the floor, then press back up. If bodyweight dips are too easy, add weight with a dip belt. If they are too hard, use an assisted dip machine or do bench dips to build the movement pattern first.
5. Cable tricep pushdown
Best for: Lateral head, excellent for isolation and pump
Equipment: Cable machine with rope or bar attachment
The pushdown is the most commonly performed triceps exercise and also the most commonly performed incorrectly. The two most common errors are letting the elbows drift forward and using too much weight, which causes the shoulders and back to take over.
Stand close to the cable stack, pin your elbows to your sides, and push the attachment down until your arms are fully extended. At the bottom, rotate your wrists slightly outward with a rope attachment to maximize the contraction. Then let the weight come back up in a controlled way — do not let it snap up.
6. Diamond push-ups
Best for: Medial and lateral head, bodyweight option requiring zero equipment
Equipment: None
Place your hands directly under your chest with thumbs and index fingers touching to form a diamond shape. Lower your chest toward your hands while keeping elbows close to the body, then press back up. This variation significantly increases triceps activation compared to standard push-ups.
Diamond push-ups are harder than they look. If you cannot complete 5 with good form, start with hands slightly wider and gradually narrow the grip as you get stronger.
7. Dumbbell kickback
Best for: Lateral head, peak contraction and definition
Equipment: Dumbbell, bench
Hinge forward at the hips with your upper arm parallel to the floor. Extend the dumbbell straight back until your arm is fully extended, hold for a beat at the top, then return slowly. The key is keeping the upper arm stationary throughout — the only thing moving should be your forearm.
Kickbacks are best done with lighter weight and controlled reps. Trying to go heavy ruins the movement pattern and removes the triceps from the equation.
8. Tricep dips (bench)
Best for: Beginners, bodyweight training at home
Equipment: A sturdy chair or bench
Sit on the edge of a chair or bench with hands gripping the edge beside your hips. Slide your body off the edge and lower yourself by bending your elbows to about 90 degrees, then push back up. Keep your back close to the chair or bench throughout the movement.
Extend your legs further in front of you to increase difficulty. This is one of the most accessible triceps exercises for beginners working out at home.
How to Structure a Triceps Workout
A complete triceps session should take 20-30 minutes and include compound pressing, overhead work, and isolation. Here is a sample structure based on the exercises above:
| Exercise | Sets | Reps | Focus |
|---|---|---|---|
| Close-grip bench press | 4 | 6-8 | Mass, heavy compound |
| Overhead dumbbell extension | 3 | 10-12 | Long head stretch |
| Cable pushdown (rope) | 3 | 12-15 | Lateral head isolation |
| Skull crushers | 3 | 10-12 | Thickness and medial head |
Rest 60-90 seconds between sets for isolation exercises, and 2-3 minutes between sets of close-grip bench press. Train triceps 2 times per week with at least 48 hours of recovery between sessions.
Common Triceps Training Mistakes
Only doing pushdowns. Pushdowns are a great isolation exercise but they barely touch the long head. If pushdowns are your only triceps work, you are leaving a third of the muscle undertrained.
Flaring the elbows. Letting elbows drift out wide during any triceps exercise shifts the load away from the triceps and toward the shoulders and chest. Keep elbows tucked or pointed in the direction of the movement.
Skipping the lockout. Full elbow extension at the top of every rep maximizes triceps contraction. Stopping short of lockout reduces the range of motion and the muscle activation that comes with it.
Too much volume, not enough intensity. Five sets of 20 light pushdowns do less for triceps growth than 3 sets of 10 close-grip bench press taken close to failure. Prioritize load and intensity over endless high-rep pump work.
Key Takeaways
- The triceps has three heads — long, lateral, and medial — each requiring different exercises to fully develop
- The long head (largest) is only fully targeted with overhead movements like overhead extensions and skull crushers
- Close-grip bench press is the best mass-builder for triceps overall
- Train triceps twice per week with compound pressing, overhead work, and isolation
- Full elbow lockout and controlled tempo matter more than using heavy weight
