For the longest time, my arms looked flat from the back. I was hitting triceps every week, doing pushdowns, dips, extensions. But nothing really changed. It was frustrating.
Then I learned about the medial head and how most people, including me, were barely training it.
Once I shifted my focus, things moved fast. The thickness I was chasing finally started showing up.
In this blog, I'm sharing the 13 best medial head tricep exercises that made the biggest difference for me personally.
I'll also cover tips that most people skip, how often you should train this muscle, and everything I wish someone had told me sooner.
If your triceps feel stuck, this is exactly where to start.
Understanding the Medial Head of the Triceps
The triceps has three parts: the long head, lateral head, and medial head. The medial head sits on the inner lower part of the upper arm.
It is the most active of the three during tricep movements. Even though it's mostly hidden beneath the other heads, it does a lot of the work.
Training it builds thickness, adds fullness to the arm, and supports your elbow joint.
Without proper attention to this muscle, your tricep development stays incomplete. Most lifters skip it without knowing.
13 Best Medial Head Tricep Exercises for Muscle Growth
These 13 moves are the most effective ways to target and grow the medial head.
1. Reverse-Grip Cable Pushdown
This is one of the top moves for the medial head. Flipping your grip so your palms face up shifts more tension onto the inner part of the tricep.
Keep your elbows at your sides and press all the way down. The full extension at the bottom is key. I noticed real thickness gains when I added this to my routine.
2. Close-Grip Bench Press
The close-grip bench press is a compound move that puts serious load on all three tricep heads, with strong emphasis on the medial head.
Keep your hands about shoulder-width apart. Tuck your elbows slightly. This also builds pressing strength fast, which carries over to your chest work.
3. Reverse-Grip Bench Press
Similar to the regular bench press but with an underhand grip. This simple grip change forces the medial head to take on more work.
It feels awkward at first, but the muscle activation is noticeably different. Use a light weight to start and focus on control throughout the movement.
4. Diamond Push-Ups
No equipment needed. Place your hands in a diamond shape under your chest and lower yourself down with control.
The narrow hand position puts direct pressure on the triceps, especially the medial head. This is a great option for home workouts or as a warm-up before heavier tricep training.
5. Cable Rope Pushdown
A classic tricep move. Using a rope attachment lets you spread the handles apart at the bottom, which increases the range of motion and activates the tricep more fully.
Keep tension on the muscle throughout. Don't let the weight pull your elbows up. Go slow on the way back up.
6. Bench Dips
Bench dips are simple but effective. Place your hands on a bench behind you, feet on the floor, and lower your body by bending your elbows.
The medial head gets hit well here, especially when your elbows stay tucked. Add weight across your lap to make this more challenging over time.
7. Skull Crushers
Lie on a bench and lower a barbell or dumbbells toward your forehead. This isolates the triceps well and works all three heads.
The medial head stays active throughout the full range. Go slow on the way down. This move has long been a staple in arm training for a good reason.
8. JM Press
The JM Press is a hybrid between a close-grip bench press and a skull crusher. It loads the triceps heavily and is great for building size.
Lower the bar to just above your chin while keeping your elbows slightly in front. This move is less common but highly effective for medial head growth.
9. Dumbbell Tricep Press
Hold a dumbbell with both hands above your chest, then lower it slowly by bending your elbows. This keeps constant tension on the triceps.
The medial head works hard during the lowering phase. It's a smooth, joint-friendly option that works well at higher rep ranges.
10. Tricep Kickbacks
Hold a dumbbell in one hand, lean forward slightly, and extend your arm straight back. This move fully extends the elbow, which is where the medial head is most active.
Don't rush it. Squeeze at the top. Tricep kickbacks get dismissed too often. Done right, they are solid.
11. Tate Press
Lie on a bench and hold two dumbbells above your chest with your palms facing your feet. Lower the dumbbells toward your chest by flaring your elbows out, then press back up.
The Tate Press is less common but targets the medial head very directly. Try it once and you'll feel the difference.
12. Single-Arm Overhead Tricep Extension
Hold one dumbbell behind your head with one hand and press it straight up. This puts the long head on stretch but also forces the medial head to work hard at full extension.
Single-arm work also helps you spot and fix imbalances between sides. Keep your core tight throughout.
13. Cable Overhead Tricep Extension
Set the cable pulley high, grip the rope or bar, and press the weight forward and down while keeping your elbows steady.
The overhead position puts the tricep in a stretched state, which adds to muscle growth over time. This is a great finisher at the end of a tricep session.
How to Target the Medial Head More Effectively
Train overhead, the medial head peaks at full arm extension.
Use Reverse-Grip Variations
Switching to an underhand grip on pushdowns or bench presses changes which part of the tricep works hardest.
The medial head responds strongly to this grip change. Even a small shift in hand position can make a big difference in where you feel the exercise.
Keep Your Elbows Tucked Close
Flared elbows shift the work away from the triceps. Keeping elbows close to your body during pressing and pushdown movements keeps the focus where it belongs.
This is one of the most common form mistakes that limits medial head activation.
Focus on Full Elbow Extension
The medial head is most active when your elbow reaches full extension. Make sure you lock out completely on every rep.
Stopping short cuts off the most important part of the movement. Don't rush through reps. A full lockout is non-negotiable if growth is your goal.
Control the Eccentric Portion
The lowering phase of any exercise is where a lot of muscle damage and growth happens. Slowing down the eccentric.
Which is the part where you return to the start position, keeps tension on the medial head longer. Two to three seconds on the way down is a good target.
Train With Moderate to High Repetitions
The medial head responds well to volume. Training in the 10 to 20 rep range with solid form gives the muscle more time under tension.
Heavy low-rep work still has its place, but mixing in higher rep sets is worth it for this particular head of the tricep.
Benefits of Training the Medial Head of the Triceps
Training the medial head gives your arms a fuller, more complete look.
Improves Overall Arm Definition
When the medial head is well-developed, the entire arm looks more defined. It fills in the area that often looks flat on the back of the upper arm.
Increases Pressing Strength
The medial head plays a big role in all pressing movements. A stronger medial head means more power on bench press, overhead press, and push movements in general.
Supports Elbow Stability
The medial head wraps around the elbow joint and helps keep it stable. Training it regularly can reduce elbow strain and lower the risk of discomfort during heavy upper body work.
Creates More Balanced Arm Development
Focusing only on the long head or lateral head leaves the arm looking uneven. Training the medial head rounds out your arm development and creates a more proportional look from all angles.
How Often Should You Train the Medial Head?
Training the medial head two to three times per week works well for most people.
Since the triceps already get work during chest and push day sessions, you don't need to train them in isolation every single day.
Give the muscle at least 48 hours to recover between sessions. If you train chest on Monday, you can hit direct tricep work on Wednesday or Thursday.
Stacking tricep training right after push day is one of the most efficient setups. Just keep the volume manageable so you don't overdo it.
Conclusion
I spent a long time training triceps without ever focusing on the medial head. My arms looked decent but never quite full.
Once I started adding reverse-grip moves and really locking out each rep, everything changed.
If your triceps have been stuck, try the medial head tricep exercises in this blog. Start with two or three. Focus on form first.
