What do Military Presses Workout?
Understanding the Military Press Exercise
The military press, also known as the dumbbell press or shoulder press, is a compound exercise that targets multiple muscle groups in the upper body, particularly the deltoids. This exercise is a classic weightlifting staple that involves lifting a dumbbell or barbell from the starting position to shoulder height. When done correctly, the military press can improve overall upper body strength, muscle mass, and aesthetic appeal.
Primary Muscles Worked
1. Deltoids: The deltoids, comprising the anterior, lateral, and posterior heads, are the primary muscles targeted during the military press.
- Anterior head: responsible for shoulder extension and forward rotation
- Lateral head: responsible for shoulder abduction (movement away from the midline) and external rotation
- Posterior head: responsible for shoulder extension and internal rotation
Secondary Muscles Involved
1. Trapezius muscle: helps stabilize the shoulders and scapula, as well as assist with scapular rotation.
2. Serratus anterior muscle: provides assistance with shoulder rotation, arm flexion, and shoulder blade protraction (winging).
3. Rhomboids muscle: assists with scapular retraction and lower trap elevation.
Additional Muscles Impacted
- Supraspinatus muscle: helps guide the humerus (upper arm bone) into an optimal position for shoulder depression.
- Infraspinatus muscle: helps with shoulder rotation.
- Teres major muscle: assists with posterior deltoid contraction.
Muscle Synergy During the Military Press
Effective performance of the military press requires muscle coordination and synergy between:
- Agonists (primary movers):
- Deltoids (anterior, lateral, and posterior heads)
- Synergist (assisting movers):
- Trapezius, serratus anterior, and rhomboids
- Stabilizers (assistants):
- Rotators (supraspinatus, infraspinatus, and teres major)
Benefits and Results
Performing military presses regularly can lead to:
- Increased strength, muscle mass, and endurance in the delts and other secondary muscle groups.
- Enhanced shoulder stability and posture.
- Reduced risk of shoulder injuries associated with poor posture, flexibility, or biomechanics.
Proper Technique for the Military Press
1. Positioning: Stand with a slight toe and shoulder distance from a wall or platform, as necessary.
2. Grip: Hold a dumbbell or barbell with overhand grips (palms facing away).
3. Starting position: Lie back, extend the hips and knees, and rotate the shoulders forward to minimize any forward leaning.
4. Press movement: Lift the weight until the upper arms are fully extended and the dumbbell is aligned with the ears or shoulders, ensuring correct tricep alignment.
5. Lowering movement: Control the lowering movement, allowing the elbows to bend, and bring the dumbbell back down to the starting position in a smooth, flowing motion.
Programming the Military Press
Including military presses in your weightlifting routine offers versatility:
- Add variety to your overall upper body training.
- Enhance progressive overload by incorporating different reps, sets, and frequencies.
Example Military Press Routine
- Volume and frequency:
- 3 sets per side (6 total), 2-3 times a week
- Progressive overload:
- Increase weight over time to continue challenging your muscles.
- Crescendo and fade: Gradually increase volume or weight in the second set, and then descend or decrease volume in the final set.
Troubleshooting and Safety Precautions
- Incorrect form: Avoid placing unnecessary strain on the lower back or shoulders by practicing proper form and engaging secondary muscle groups.
- Shoulder injuries: Regular stretching, self-myofascial release, or working with a qualified instructor can help mitigate the risk of shoulder injuries.
Conclusion: The military press workout engages multiple muscle groups to strengthen the shoulders, posture, and overall upper body. Mastering proper technique, incorporating this exercise into your routine, and adapting to progressive overload will help you achieve positive results and minimize the risk of injury.
