French Press Exercise: How to Do It & Why It Works

Quick answer: The French press (also called an overhead triceps extension) is one of the most effective triceps exercises specifically because raising your arms overhead stretches the long head of the triceps — and research shows training a muscle in this stretched position drives meaningfully more muscle growth than training it in a neutral position, like a standard triceps pushdown.

The French press is an overhead arm-extension exercise that isolates the triceps, the three-headed muscle making up roughly two-thirds of your upper arm’s muscle mass. While it’s often treated as just another triceps accessory movement, there’s a real, research-backed reason it deserves a specific place in your program rather than being interchangeable with other triceps exercises.

What Makes the French Press Mechanically Different

Your triceps has three heads — lateral, medial, and long — and the long head is unique because it’s biarticular, meaning it crosses both your elbow and shoulder joints, rather than just the elbow like the other two heads. This matters directly for the French press: because your arm is raised overhead during the movement, the long head gets stretched across both joints simultaneously, unlike exercises performed with your arms at your sides.

What the Research Shows About This Stretched Position

A study published in the European Journal of Sport Science directly compared triceps training performed in the overhead position against the same movement performed in a neutral (arms-down) position over a 12-week program. The researchers found that triceps hypertrophy was substantially greater after training in the overhead position, particularly in the long head specifically — and notably, this happened even though the overhead position involved lifting less absolute weight than the neutral position, since the overhead position is mechanically more demanding for the same load.

This lines up with a broader, growing body of research on “stretch-mediated hypertrophy” — the finding that training a muscle through a position where it’s under a meaningful stretch tends to be a particularly effective stimulus for muscle growth, sometimes even more effective than training through other parts of the range of motion alone.

How to Perform the French Press Correctly

1. Setup: Sit on a bench with back support, or stand with feet shoulder-width apart. Hold a dumbbell, EZ bar, or barbell with an overhand grip.
2. Starting position: Raise the weight straight overhead until your arms are fully extended, elbows pointing up toward the ceiling.
3. Lowering phase: Keeping your upper arms stationary and elbows tucked in (not flared out), slowly bend your elbows to lower the weight behind your head, feeling a stretch through your triceps.
4. Lift phase: Extend your elbows to press the weight back to the starting overhead position, squeezing your triceps at the top.
5. Repeat for your desired number of reps, keeping the movement controlled throughout — this isn’t an exercise to rush, especially given the stretched position places real demand on the muscle at the bottom of each rep.

Common Form Mistakes

• Letting your elbows flare outward during the movement, which shifts tension away from the triceps and can add unnecessary stress to the shoulder joint. Keep elbows tucked and relatively fixed in position throughout.
• Using too much weight, which can add stress to your elbows and shoulders and increase injury risk — this exercise rewards control more than raw load, especially given the joint positions involved.
• Arching your lower back if performing the movement standing, which places unnecessary strain on your spine. Keep your core braced and avoid excessive arch.
• Rushing the eccentric (lowering) phase, which skips much of the benefit of training through the stretched position that makes this exercise effective in the first place.

Variations to Fit Your Setup

• Seated French press — removes some of the stabilization demand from your core and lower back, letting you focus more directly on the triceps
• Lying French press (skull crusher) — performed lying on a bench, this uses a somewhat different range of motion and is often considered a related but distinct movement from the standing/seated overhead version
• Dumbbell variation — training one arm at a time can help identify and address any strength asymmetries between your left and right triceps
• Cable variation — offers more consistent tension throughout the range of motion compared to free weights, similar to the tension-curve differences we’ve discussed for other exercises on this site

Who Should Be Cautious With This Exercise

The overhead elbow position does place real demand on both your shoulder and elbow joints. If you have existing shoulder impingement, elbow tendon issues, or general shoulder sensitivity, this exercise may not be the right starting point — a lighter-load, well-controlled introduction (or an alternative triceps exercise performed in a more neutral position) may be more appropriate until those areas are more resilient.

How This Fits Into a Broader Arm-Training Program

The French press works well as a dedicated, stretch-focused triceps movement alongside other triceps and arm work. Our Inner Arm Transformation guide covers additional exercises for building overall arm definition, and if you’re incorporating kettlebell work into your routine, our 20-Minute Kettlebell Arm Masterclass covers a complementary approach using different equipment.

A Simple Way to Program This

Given the research supporting the overhead, stretched position specifically for long head development, a reasonable approach is including the French press (or a similar overhead triceps movement) as one of 2-3 total triceps exercises in your weekly routine, alongside a pushdown-style movement (which more effectively targets the other two triceps heads) for balanced overall triceps development.

Frequently Asked Questions

Is the French press better than triceps pushdowns?
Research suggests overhead extensions like the French press are particularly effective for the long head specifically, while pushdown-style movements are perfectly effective for the other two triceps heads — a well-rounded program benefits from including both rather than choosing one exclusively.

How much weight should I start with?
Start conservatively, since the overhead position is more mechanically demanding on the joints than exercises performed with your arms at your sides — you should be able to maintain full control and a fixed elbow position throughout the set.

Is the French press the same as a skull crusher?
They’re closely related but not identical — both work the triceps through elbow flexion and extension, but the lying skull crusher variation uses a somewhat different range of motion and body position than the standing or seated overhead French press.

Bottom Line

The French press earns its place in a triceps program for a specific, research-backed reason: the overhead arm position stretches the biarticular long head of the triceps in a way that neutral-position exercises simply can’t replicate, and that stretched position appears to be a particularly effective stimulus for muscle growth. Performed with controlled form and appropriate weight, it’s a genuinely valuable addition alongside other triceps exercises like pushdowns, rather than an interchangeable substitute for them.
