Upper Arms Exercise · Barbell
Biomechanical cues verified by the PlanWorkouts Science Review Board under CSCS editorial oversight; see our editorial standards.
The Barbell Pin Presses is a targeted isolation upper arms movement designed to train the Triceps.
Single-joint elbow extension isolating the triceps brachii (lateral, medial, and long heads). Keep upper arm fixed to prevent shoulder momentum. Executing this with strict form maximizes muscle fiber recruitment while protecting joint structures.
Quick Exercise Facts
Target Muscle Activation
Pin presses start the bar from a dead stop on safety pins set at a specific height, removing the stretch reflex and any bounce out of the bottom. That makes it one of the better tools for building strength at a sticking point, since you can set the pins right at the height where your press usually stalls. It's an accessory movement, not a replacement for full range-of-motion pressing.
How to Do the Barbell Pin Presses
- Set a barbell on a power rack at chest height.
- Position yourself facing the barbell, standing underneath it with your feet shoulder-width apart.
- Grip the barbell overhand, hands slightly wider than shoulder-width.
- Lift the barbell off the rack and hold it directly above your chest with your arms fully extended.
- Lower the barbell toward your chest, keeping your elbows tucked close to your body.
- Pause briefly once the barbell touches your chest.
- Press the barbell back up to the starting position, fully extending your arms.
- Repeat for your desired repetitions, keeping constant tension on the working muscle throughout.

Controlled 3s eccentric · 60s rest
Biomechanical & Joint Load Cues
Single-joint elbow extension isolating the triceps brachii (lateral, medial, and long heads). Keep upper arm fixed to prevent shoulder momentum.
Common Mechanical Mistakes & Form Errors to Avoid
- Flaring Elbows Outward: Allowing elbows to wing outward during pushdowns or extensions shifts tension to the chest and shoulders while stressing elbow ligaments.
- Moving the Upper Arms: Swinging the humerus back and forth turns the movement into a lat pullover rather than isolated elbow extension.
- Incomplete Lockout Extension: Stopping short of full arm extension prevents full recruitment of the triceps medial and lateral heads.
Proper Breathing Patterns & Core Engagement
Inhale as elbow flexes to full stretch; exhale as forearm extends straight.

Injury Modification & Joint Safety
Individuals with triceps tendon irritation at the elbow should avoid excessive deep elbow flexion (>90°) on skull crushers and prefer cable pressdowns. If joint irritation persists, immediately stop and substitute this movement with another exercise from the Upper Arms exercises category.
Muscles Worked

FAQ
- What muscles does the Barbell Pin Presses work?
- The Barbell Pin Presses primarily targets the triceps as the primary agonist. The shoulders acts as the primary supporting muscle group during force transmission. Maintaining strict biomechanical alignment ensures maximal tension remains focused on the intended muscle fibers rather than shifting to surrounding stabilizer joints.
- What equipment do I need for the Barbell Pin Presses?
- The Barbell Pin Presses is performed using a barbell. Ensure all equipment is securely positioned with collars or safety pins locked before loading working sets. If you train in a home gym or minimal setup, explore our equipment-free and resistance band alternatives below.
- What is the most common form mistake on the Barbell Pin Presses?
- The most frequent error is flaring elbows outward: Allowing elbows to wing outward during pushdowns or extensions shifts tension to the chest and shoulders while stressing elbow ligaments.. Controlling the 2 to 3-second eccentric lowering phase ensures maximal hypertrophic stimulus while shielding connective tissue.
- How many sets and reps should I perform on the Barbell Pin Presses?
- For muscle growth and density, execute 3 to 4 working sets of 10 to 15 controlled repetitions with 60 seconds rest, emphasizing a deep stretch and deliberate peak contraction on every rep.
- What's a good alternative to the Barbell Pin Presses?
- If you don't have access to a barbell, the Bench Dip (knees Bent) targets the same triceps using body weight instead. This alternative replicates the same joint angle and movement plane while allowing you to train effectively with different available gear.
