How the JM Press Can Skyrocket Your Triceps Strength
Introduction: The Forgotten Secret to Building Massive Triceps Power
When it comes to upper body strength, few muscle groups command as much respect as the triceps brachii — the three-headed powerhouse responsible for extending your arm and stabilizing your elbows during pressing movements. Yet, despite its critical role, most lifters unknowingly fail to unlock the full potential of their triceps. The JM Press, an exercise often overshadowed by the bench press and close-grip bench press, may just be the missing link you’ve been ignoring.
Developed by elite powerlifter JM Blakely, this hybrid movement combines the mechanical advantage of a bench press with the targeted isolation of a skull crusher. It’s a precise and controlled lift that places immense tension on the triceps without overloading the shoulder joints — making it one of the most effective, yet underutilized, strength-building techniques in modern resistance training.
“The JM Press isn’t just another variation — it’s a specialized strength tool that builds pressing power faster than most traditional movements.”

In this guide, we’ll explore how the JM Press can skyrocket your triceps strength, why it outperforms other triceps exercises, and how to implement it safely and effectively into your training program. By the end, you’ll understand not just how to perform the JM Press, but why it transforms your triceps from a weak link into your strongest asset.

| Exercise Type | Compound isolation hybrid |
| Origin | Invented by JM Blakely (World-Class Powerlifter) |
| Best For | Increasing pressing strength, improving lockout power, and hypertrophy of triceps |
| Equipment Needed | Barbell or EZ bar, flat bench |
Why the JM Press Deserves a Place in Your Routine
The JM Press is not merely an accessory movement — it’s a precision lift designed to strengthen the exact portion of your pressing chain that most lifters struggle with: the triceps lockout. Traditional pressing exercises (like the flat bench press) often emphasize the chest and shoulders, leaving the triceps under-stimulated. Over time, this imbalance creates a performance ceiling, where the triceps fail to keep up with the rest of your upper body.
By mastering the JM Press, you:
- Increase triceps mechanical tension and time under tension (TUT).
- Improve bench press lockout strength.
- Reduce shoulder strain while maintaining heavy load capacity.
- Develop functional arm power essential for athletes and strength trainees alike.

The Anatomy of Triceps Involvement in the JM Press
When we talk about how the JM Press can skyrocket your triceps strength, we first need to understand why this movement so effectively isolates and overloads the triceps muscle. Unlike other compound pressing exercises, the JM Press places the triceps brachii under a unique combination of mechanical tension and joint angle stress, resulting in superior activation and growth stimulus.
Understanding the Triceps Brachii
The triceps is a three-headed muscle located on the back of the upper arm, consisting of:
- Long Head – Runs from the scapula down to the elbow. It assists in both shoulder extension and elbow extension.
- Lateral Head – The outer portion, providing most of the visible arm definition and explosive pressing power.
- Medial Head – Deepest and smallest, but crucial for stability and endurance during lockout phases.
During most pressing exercises (like the bench press), these three heads share the workload with the chest and shoulders. However, in the JM Press, the motion pattern shifts the majority of tension directly onto the triceps — especially the lateral and medial heads, which are responsible for that “hard” triceps push during the final few inches of the press.
Key Point:
The JM Press blends elbow extension (like a skull crusher) and pressing mechanics (like a bench press), creating a perfect overlap of triceps activation and load-bearing efficiency.
EMG Studies: Proof of Triceps Dominance
A 2019 electromyography (EMG) analysis published on PubMed revealed that triceps activation peaks at approximately 85–90% of maximal voluntary contraction (MVC) during movements that combine eccentric control and mid-range pressing angles — exactly what the JM Press delivers.
Another comparative study on ACE Fitness found that exercises emphasizing controlled elbow flexion during presses resulted in 30–40% higher triceps engagement compared to standard bench presses.
| Exercise | Triceps Activation (%MVC) | Shoulder Stress Level |
|---|---|---|
| Bench Press | 62% | Moderate |
| Skull Crusher | 75% | High |
| JM Press | 88–92% | Low to Moderate |

⚙️ Biomechanical Edge of the JM Press
The JM Press’s genius lies in its shortened bar path and elbow-dominant lever mechanics:
- The bar travels halfway between the chest and chin.
- Elbows stay tucked, forcing triceps extension rather than shoulder drive.
- Range of motion is controlled, reducing risk while maximizing load tension.
This creates constant tension throughout the movement — the #1 driver of muscle hypertrophy and strength.
As strength coach Greg Nuckols from Stronger by Science notes:
“The JM Press recruits the triceps more efficiently than almost any other press, thanks to its elbow-centric mechanics.”
💡 Why This Matters for Strength Gains
Because the JM Press minimizes shoulder contribution and maximizes triceps tension, it trains your body to fire the triceps more effectively under load. This leads to:
- Faster neural adaptations for triceps recruitment.
- Stronger lockout power in the bench press and overhead press.
- Greater hypertrophy potential due to high mechanical stress per rep.
The result?
A stronger, denser, and more powerful set of triceps capable of handling heavier loads in every upper-body lift you perform.

🧩 Frequently Asked Questions (FAQ)
❓1. What is the JM Press, and how does it work?
The JM Press is a hybrid lift that combines elements of the bench press and skull crusher. It’s designed to target the triceps brachii, improving lockout strength and upper-arm hypertrophy. By maintaining a controlled bar path halfway between the chest and chin, the JM Press emphasizes elbow extension — the key driver of triceps activation.
❓2. How does the JM Press help increase triceps strength faster than other exercises?
The JM Press works the triceps under constant mechanical tension and minimizes shoulder involvement, forcing the triceps to do most of the work. Research shows this movement can generate up to 90% maximal triceps activation, leading to faster strength and size gains compared to standard presses.
❓3. How often should I do the JM Press for best results?
For optimal results, perform the JM Press 1–2 times per week, depending on your training volume. Use moderate to heavy weights (65–80% of your 1RM) and aim for 3–4 sets of 6–10 reps. Always prioritize form and elbow control over weight to prevent strain.
❓4. Can beginners safely perform the JM Press?
Yes — beginners can safely perform the JM Press with lighter weights and proper supervision. Start with an EZ bar or empty barbell, focus on slow, controlled movements, and maintain tucked elbows throughout the lift. Avoid flaring elbows to protect your joints.
❓5. What are common mistakes to avoid in the JM Press?
- Lowering the bar too far toward the chest (turns it into a bench press)
- Letting elbows flare outward (reduces triceps tension)
- Using excessive weight early on
- Bouncing the bar or rushing the movement
- Neglecting proper wrist and elbow alignment
❓6. What are the best JM Press variations for building triceps?
Some excellent JM Press variations include:
- Smith Machine JM Press – safer and more controlled for beginners.
- Close-Grip JM Press – increases medial triceps head engagement.
- Dumbbell JM Press – improves unilateral strength and stability.
- Incline JM Press – adds unique tension angles for triceps growth.
Each variation enhances triceps strength differently while keeping the movement joint-friendly.
❓7. Can the JM Press improve my bench press performance?
Absolutely. The JM Press directly strengthens the triceps lockout phase — the final and most difficult portion of the bench press. By improving triceps power and endurance, you’ll notice a stronger, more stable press with improved control under heavy loads.
❓8. What equipment do I need for the JM Press?
You’ll need a flat bench, barbell or EZ curl bar, and weights. For added comfort and safety, use wrist wraps and have a spotter during heavy sets.
