Hammer Military Press

The hammer military press is a dumbbell shoulder press performed with a neutral, palms-facing-inward grip instead of the pronated grip used in a standard military press. This grip orientation keeps the wrists and elbows in a more natural line during the press, reducing strain on the shoulder joint while still building significant pressing strength. It targets the deltoids as the prime mover, with heavy assistance from the triceps and upper chest. The neutral grip also makes it a useful option for lifters who experience shoulder discomfort with a barbell overhead press.

Muscles Targeted

• Primary: Anterior and lateral deltoids
• Secondary: Triceps brachii, upper pectoralis major
• Tertiary: Trapezius, core stabilizers

Starting Position

Stand with feet shoulder-width apart, holding a dumbbell in each hand at shoulder height with palms facing each other (neutral grip) and elbows pointing forward and slightly out. Brace your core and keep your ribs stacked over your pelvis to avoid arching your lower back. This is your starting position, whether performed standing or seated on an upright bench.

Execution Steps

1. Brace your core and set your feet or seated base before pressing
2. Press both dumbbells straight overhead, keeping the neutral grip throughout the movement
3. Extend your arms fully at the top without locking the elbows aggressively, bringing the dumbbells close together overhead
4. Pause briefly at full extension to confirm control
5. Lower the dumbbells back to shoulder height under control, keeping the neutral grip and elbows tracking forward
6. Reset your position before initiating the next rep, avoiding any bounce out of the bottom

Form Cues

• Keep the grip neutral throughout: Palms should stay facing each other from start to finish - don't rotate into a pronated grip mid-rep
• Avoid excessive lower back arch: Keep your ribs down and core braced to press straight up rather than leaning back
• Press in a straight line: The dumbbells should travel directly overhead, not forward and up
• Control the descent: Lower the weights at the same speed you pressed them - don't let gravity accelerate the eccentric
• Keep your head neutral: Move it slightly back to let the dumbbells pass, then return to neutral once they clear your face

Common Mistakes

• Arching the lower back: Leaning back to help drive the weight up shifts stress to the spine. Keep the core braced and ribs down throughout the press.
• Flaring the elbows too wide at the bottom: This places unnecessary stress on the shoulder joint. Keep the elbows tracking roughly forward under the dumbbells.
• Partial range of motion: Stopping short of full elbow extension or not returning fully to shoulder height reduces the training stimulus. Complete the full range each rep.
• Using leg drive unintentionally: Turning the exercise into a push press without deciding to do so recruits momentum and hides weakness. Keep it a strict press unless leg drive is intentional.
• Pressing too much weight: Excess load causes the movement to break down into a lean-back push. Select a weight you can control through the full range with strict form.

Variations

• Seated hammer press: Removes leg drive and core-stabilization demand, isolating the shoulders and triceps further
• Standard barbell military press: Uses a pronated grip and fixed bar path, allowing heavier total loading
• Arnold press: Adds a rotational component from bottom (palms in) to top (palms forward), increasing range of motion and deltoid activation
• Single-arm hammer press: Unilateral variation that adds core anti-lateral-flexion demand
• Push press (hammer grip): Adds leg drive to move heavier loads or push through a sticking point

Tips for Progression

• Increase load gradually: Add small increments once you can complete all sets and reps with strict form
• Build volume first: Progress to 10-12 reps before increasing weight
• Add tempo work: Slow the eccentric to 3 seconds to increase time under tension
• Progress from seated to standing: Master the seated version before adding the core-stability demand of the standing variation

Training Notes

Include the hammer military press 1-2 times per week as a primary or secondary shoulder-pressing movement, typically performed early in a shoulder or upper-body session while fresh. Work in the 8-12 rep range for 3-4 sets, resting 90 seconds to 2 minutes between sets given the moderate-to-heavy loading. It pairs well as an alternative or complement to barbell overhead pressing for lifters managing shoulder sensitivity.
