What Tricep Workout Hits the Medial Head Best for Size?
What Tricep Workout Hits The Medial Head
The triceps muscle is the powerhouse behind every strong push, press, and extension. Many gym-goers focus on building big arms, but most do not realize the triceps make up about two-thirds of the upper arm’s size. The medial head of the triceps is less visible than the lateral or long head, yet it plays a crucial role in arm strength, endurance, and muscle balance. If your goal is well-developed, functional arms, understanding and targeting the medial head is essential.
This article explores the best tricep workouts for hitting the medial head. You’ll learn how the medial head works, why it's important, and which exercises are most effective. We’ll break down the science, provide practical tips, and include actionable routines.
By the end, you’ll know exactly how to build stronger, more balanced triceps.
Understanding The Triceps: Anatomy And Function
The triceps brachii is a three-headed muscle on the back of the upper arm. Each head has a unique function:
- Long head: Runs along the back of the arm and assists with shoulder extension.
- Lateral head: Creates the “horseshoe” shape and is visible on the outer side.
- Medial head: Located deeper, underneath the other two, and runs down to the elbow.
The medial head is active during all triceps movements, especially those requiring endurance or stability. It helps lock out the elbow and supports the other heads during pressing exercises. Unlike the lateral and long heads, the medial head is smaller and not as visible, but it’s essential for strength and joint support.
Why Target The Medial Head?
Most people train the triceps for size, focusing on exercises that hit the lateral or long head. However, neglecting the medial head can lead to muscle imbalance and weaker lockout strength. Here’s why you should care:
- Joint stability: The medial head helps stabilize the elbow.
- Strength endurance: It works hard during repetitive or high-rep movements.
- Balanced appearance: Strong medial head creates a fuller, balanced upper arm.
- Injury prevention: Weakness here can lead to elbow pain or injuries.
How The Medial Head Works In Tricep Movements
The medial head is engaged in almost every tricep exercise, but its activation increases with certain movements. It is most involved when the elbow is fully extended and during exercises with a neutral or pronated (palms down) grip.
Medial Head Activation: Key Insights
- Grip position matters: Using a reverse grip (palms up) or neutral grip increases medial head activation.
- Range of motion: Full extension at the elbow recruits the medial head more.
- Load and repetition: High-rep, lower-weight movements fatigue the medial head, as it’s responsible for endurance.
Many beginners overlook these factors, thinking all triceps exercises work the same. But specific tweaks to grip and form can make a big difference.
Best Tricep Exercises For The Medial Head
Not all tricep workouts are equal when it comes to targeting the medial head. The following exercises have been proven, both in studies and real-world training, to hit the medial head effectively.
1. Reverse Grip Tricep Pushdown
This exercise uses a cable machine with a straight or EZ bar. The palms face up (supinated grip), which emphasizes the medial head.
How to do it:
- Attach a straight or EZ bar to a high pulley.
- Stand upright, grab the bar with an underhand grip.
- Keep elbows close to the body.
- Push the bar down until arms are fully extended.
- Slowly return to starting position.
Why it works: The supinated grip forces the medial head to work harder. It’s also easier on the elbows compared to regular pushdowns.
2. Close-grip Bench Press
A classic compound movement, but with hands placed closer together. This variation shifts focus to the triceps, especially the medial head.
How to do it:
- Lie on a bench, grip the bar with hands shoulder-width apart.
- Lower the bar to the chest, keeping elbows close.
- Press up, fully extending arms.
Why it works: The closer grip increases triceps involvement. At lockout, the medial head is heavily recruited.
3. Dumbbell Tricep Kickbacks
Kickbacks are often underestimated, but done with strict form, they engage the medial head deeply.
How to do it:
- Hold a dumbbell, bend forward at the waist.
- Keep upper arm parallel to the ground.
- Extend the forearm back, fully straightening the elbow.
- Pause, then return.
Why it works: The full extension at the elbow ensures the medial head is working hard.
4. Rope Pushdowns
Using a rope attachment, pushdowns allow for natural wrist movement. Turning the wrists outward at the bottom increases medial head activation.
How to do it:
- Attach a rope to a cable machine.
- Stand upright, grab rope ends.
- Push down, flare wrists outward at the bottom.
- Pause briefly, then return.
Why it works: The outward wrist flare at lockout recruits the medial head more than a straight bar.
5. Diamond Push-ups
Bodyweight exercise, but with hands close together in a diamond shape under the chest.
How to do it:
- Place hands together under the chest, forming a diamond shape.
- Lower body, keeping elbows close.
- Push up, fully extending arms.
Why it works: The close hand position emphasizes the triceps, especially at the top of the movement.
6. Overhead Triceps Extensions (single Arm)
This exercise can be done with dumbbells, cables, or bands. Overhead position stretches the triceps and activates all heads.
How to do it:
- Sit or stand, hold a dumbbell overhead.
- Lower the dumbbell behind the head.
- Extend arm fully.
Why it works: The overhead stretch recruits all heads, but full extension focuses on the medial head.
7. Triceps Dips
Bodyweight or weighted, dips are powerful for triceps. Keep elbows tight and use a narrow grip.
How to do it:
- Use parallel bars or a bench.
- Lower body with elbows close to sides.
- Push up, locking out elbows.
Why it works: The elbow lockout and bodyweight stress the medial head.
8. Pronated Grip Tricep Extensions
Using a barbell or EZ bar, with palms facing down (pronated), this isolation move hits the medial head.
How to do it:
- Lie on a bench, hold bar with pronated grip.
- Lower bar to forehead or behind head.
- Extend arms fully.
Why it works: The pronated grip boosts medial head involvement.
9. Cable Overhead Extensions
Using a cable for continuous tension, this exercise focuses on the medial head at lockout.
How to do it:
- Attach rope to low pulley.
- Face away, hold rope overhead.
- Extend arms upward.
Why it works: Continuous cable tension and full extension recruit the medial head.
10. Tricep Pushdowns With V-bar
The V-bar allows a neutral grip, which is comfortable and effective for the medial head.
How to do it:
- Attach V-bar to cable.
- Grip bar with palms facing each other.
- Push down, fully extend.
Why it works: Neutral grip puts stress on the medial head during extension.
Comparing Tricep Exercises For Medial Head Activation
Many people wonder which exercises truly hit the medial head best. Let’s look at data comparing medial head activation in common tricep movements.
| Exercise | Medial Head Activation (EMG %) | Grip Type | Difficulty |
|---|---|---|---|
| Reverse Grip Pushdown | 78% | Supinated | Easy |
| Close-Grip Bench Press | 74% | Pronated | Medium |
| Diamond Push-Up | 72% | Neutral | Medium |
| Dumbbell Kickback | 69% | Neutral | Medium |
| Rope Pushdown | 67% | Neutral | Easy |
| Overhead Extension | 65% | Pronated | Hard |
EMG % refers to muscle activity measured in studies. As you can see, reverse grip pushdowns and close-grip bench presses lead the pack for medial head activation. However, the best approach is to use a mix of these exercises.

Sample Medial Head-focused Tricep Workout Routine
Let’s put theory into practice. Here’s a sample routine designed to maximize medial head activation. Use this as a weekly triceps workout or add it to your push day.
Routine Structure
- Warm-up: 5–10 minutes (light cardio, arm circles)
- Reverse Grip Pushdown: 4 sets x 12 reps
- Close-Grip Bench Press: 3 sets x 8 reps
- Dumbbell Kickbacks: 3 sets x 12 reps (each arm)
- Rope Pushdown (with wrist flare): 3 sets x 10 reps
- Diamond Push-Ups: 2 sets x 15 reps (bodyweight)
Tips For Success
- Focus on full elbow extension on every rep.
- Use slow, controlled movements—don’t let momentum cheat the medial head.
- Rest 60–90 seconds between sets for endurance.
- Adjust weights so the last two reps are difficult but with good form.
Many beginners rush reps or use too much weight. This reduces medial head involvement and can cause elbow pain. Quality is more important than quantity.
Advanced Techniques For Targeting The Medial Head
Once you master basic exercises, try these advanced methods to further stimulate the medial head.
1. Isometric Holds
Pause at the end of each rep (elbow fully extended) for 2–3 seconds. This increases time under tension and forces the medial head to stabilize.
2. Drop Sets
After your last set, reduce the weight by 30% and perform reps to failure. This fatigues the medial head, which is responsible for endurance.
3. Partial Reps
Perform the last 5 reps only in the extended range (top half). This keeps tension on the medial head.
4. Supersetting
Pair two tricep exercises back-to-back (e. g. , reverse grip pushdown + diamond push-up) to exhaust the medial head.
| Technique | Medial Head Focus | Best Exercise Pair |
|---|---|---|
| Isometric Holds | High | Kickbacks + Pushdown |
| Drop Sets | Medium | Pushdown + Rope Extension |
| Partial Reps | High | Bench Press + Diamond Push-Up |
| Supersetting | Medium | Pushdown + Overhead Extension |

Common Mistakes When Training The Medial Head
Even experienced lifters make errors that limit medial head growth. Here are mistakes to avoid:
- Neglecting grip variation: Only using one grip (pronated) misses medial head activation.
- Not locking out the elbow: Partial reps cheat the medial head.
- Using too much weight: Poor form means other muscles take over.
- Training only with compound movements: Isolation exercises are needed for full activation.
- Skipping wrist movement: Flared wrists at lockout recruit more medial head fibers.
Many beginners think all triceps exercises are equal. But small adjustments in grip, form, and range of motion make a huge difference.
How To Progress And Keep The Medial Head Growing
Building the medial head is about consistency and smart progression. Here’s how to keep improving:
- Increase reps: The medial head responds well to high-rep sets (12–15).
- Add new grips: Change grip every 2–3 weeks to keep the muscle challenged.
- Track performance: Log weights, reps, and grip type for each workout.
- Include bodyweight moves: Diamond push-ups and dips stimulate endurance.
- Use isolation exercises: Kickbacks and pushdowns should be part of every routine.
Most people plateau because they repeat the same exercises. Variety keeps the medial head growing and prevents boredom.
The Role Of Nutrition In Tricep Development
Training alone isn’t enough. Nutrition plays a major role in muscle growth, including the medial head.
Key Points
- Protein: Aim for at least 0.7–1 gram per pound of bodyweight.
- Carbs: Fuel your workouts with complex carbs (rice, potatoes, oats).
- Healthy fats: Support hormones and joint health (avocado, nuts, olive oil).
- Hydration: Water aids recovery and performance.
Many beginners focus only on training and neglect nutrition. Without enough protein and calories, the medial head will not grow.
Recovery And Injury Prevention For The Medial Head
Overtraining or poor form can lead to elbow pain and injury. Recovery is essential for progress.
Recovery Tips
- Rest days: Allow triceps at least 48 hours between workouts.
- Stretching: Gentle tricep stretches after workouts prevent tightness.
- Foam rolling: Helps reduce soreness and improve blood flow.
- Listen to your body: Pain is a signal to stop and reassess form.
Ignoring recovery is a common mistake, especially for beginners. The medial head is small and easily fatigued, so rest is critical.
Medial Head Training For Different Fitness Levels
Whether you’re a beginner or advanced, training the medial head can be adapted.
| Fitness Level | Recommended Exercise | Reps/Sets | Tip |
|---|---|---|---|
| Beginner | Reverse Grip Pushdown | 3 x 12 | Focus on form |
| Intermediate | Close-Grip Bench Press | 4 x 8 | Increase weight |
| Advanced | Kickbacks + Drop Sets | 5 x 12 + drops | Use advanced techniques |
No matter your level, the key is to challenge the medial head with proper form, grip variation, and progressive overload.
Science Behind Medial Head Activation
Many studies have explored how different tricep exercises activate the medial head. EMG (electromyography) research shows:
- Reverse grip pushdown leads to the highest medial head activation.
- Diamond push-up is effective but requires good shoulder stability.
- Kickbacks and rope pushdowns are great for isolation.
Some studies suggest that the medial head is most active during endurance tasks and high-rep movements. This is why including both heavy and lighter, higher-rep exercises in your routine works best.
