Single-Arm Palm-In Dumbbell Shoulder Press Exercise
About Single-Arm Palm-In Dumbbell Shoulder Press Exercise
The Single-Arm Palm-In Dumbbell Shoulder Press is a unilateral upper-body exercise that targets the deltoid muscles, particularly the anterior and lateral heads of the shoulder. This movement involves pressing a dumbbell overhead with one arm while keeping the palm facing inward, toward the body. By working one arm at a time, this exercise helps to identify and correct strength imbalances between the left and right sides, while also engaging the core for balance and stability.
This variation of the traditional shoulder press offers a unique twist by using the palm-in (neutral) grip, which reduces stress on the shoulder joint and makes the exercise more comfortable for those with shoulder issues. It’s popular among athletes and fitness enthusiasts for its effectiveness in building shoulder strength, improving core stability, and enhancing overall shoulder mobility.
Origin of the Single-Arm Palm-In Dumbbell Shoulder Press Exercise
The Single-Arm Palm-In Dumbbell Shoulder Press evolved from the traditional dumbbell shoulder press, a staple exercise in strength training for decades. As the need for more functional and joint-friendly movements grew, fitness professionals began incorporating variations like the single-arm press with a neutral grip. This adaptation allows for a more natural shoulder movement, reducing the risk of impingement and other shoulder-related injuries while still providing the benefits of overhead pressing.
The introduction of unilateral exercises like this one into modern training programs has emphasized the importance of correcting muscle imbalances and improving functional strength. Over time, the Single-Arm Palm-In Dumbbell Shoulder Press became a go-to exercise for athletes, bodybuilders, and general fitness enthusiasts alike.
Types of the Single-Arm Palm-In Dumbbell Shoulder Press Exercise
- Seated Single-Arm Palm-In Dumbbell Shoulder Press: This variation is performed while seated on a bench, providing more support for the lower back and isolating the shoulder muscles. It reduces the involvement of the legs, allowing for a more focused shoulder workout.
- Standing Single-Arm Palm-In Dumbbell Shoulder Press: In this variation, the lifter stands while pressing the dumbbell overhead. This engages the core, lower back, and legs for added stability, making it a more functional, full-body movement.
- Kneeling Single-Arm Palm-In Dumbbell Shoulder Press: The kneeling variation enhances core engagement and balance by eliminating lower body support, requiring the core to stabilize the body during the press.
Exercise Overview
Single-Arm Palm-In Dumbbell Shoulder Press Exercise Instructions
- Start by having a dumbbell in one hand with your arm fully extended to the side using a neutral grip. Use your other arm to hold on to an incline bench to keep your balance.
- Your feet should be shoulder-width apart from each other. Now slowly lift the dumbbell until you create a 90-degree angle with your arm. Note: Your forearm should be perpendicular to the floor. Continue to maintain a neutral grip throughout the entire exercise.
- Slowly lift the dumbbell until your arm is fully extended. This is the starting position.
- While inhaling lower the weight down until your arm is at a 90-degree angle again.
- Feel the contraction for a second and then lift the weight back up towards the starting position while exhaling. Remember to hold on to the incline bench and keep your feet positioned to keep balance during the exercise.
- Repeat for the recommended amount of repetitions.
- Switch arms and repeat the exercise.
Variation: This exercise can be performed with dumbbells in each arm as the dumbbells will help to keep you balanced. This is another great way to add variety to your routines and keep them interesting.
Single-Arm Palm-In Dumbbell Shoulder Press Exercise Health Benefits
- Builds Shoulder Strength
The Single-Arm Palm-In Dumbbell Shoulder Press directly targets the deltoid muscles, particularly the front and side heads of the shoulders. By isolating one arm at a time, this exercise helps to build balanced shoulder strength and improve muscle definition. - Improves Core Stability
Since this exercise is performed with one arm at a time, the body must engage the core muscles to maintain balance and stability. This leads to enhanced core strength, improving overall posture and stability during other exercises and daily activities. - Reduces Shoulder Joint Stress
The palm-in (neutral) grip used in this exercise helps to minimize stress on the shoulder joint. It provides a more natural range of motion compared to the traditional overhead press, making it a safer option for individuals with shoulder discomfort or mobility issues. - Enhances Functional Strength
The Single-Arm Palm-In Dumbbell Shoulder Press mimics real-life movements that involve pushing or lifting objects overhead. This makes it a functional exercise that improves overall strength for daily tasks and sports activities, such as lifting, throwing, or pressing. - Corrects Muscle Imbalances
Performing this exercise unilaterally (one arm at a time) helps to identify and correct muscle imbalances between the left and right sides of the body. This promotes symmetry and balanced strength development, which is important for injury prevention. - Improves Shoulder Mobility
The neutral grip encourages a smoother, more natural shoulder movement, which can improve shoulder mobility and flexibility over time. This helps in reducing the risk of injury and enhancing performance in other overhead movements. - Engages Stabilizing Muscles
The single-arm variation of the shoulder press recruits additional stabilizing muscles in the shoulder, core, and lower back. This increases overall strength and stability, especially in situations where balance and coordination are key.
Single-Arm Palm-In Dumbbell Shoulder Press Exercise Tips
- Start with Light Weights
Begin with a light to moderate weight to master the movement and avoid shoulder strain. The neutral grip may feel different if you’re used to the traditional overhead press, so focus on technique first before increasing the load. - Engage Your Core
Since you’re pressing with one arm, your core needs to work harder to stabilize your body. Keep your abs tight and engaged throughout the movement to maintain balance and protect your lower back from unnecessary strain. - Maintain Proper Form
Keep your back straight and avoid arching your lower back during the press. Maintain an upright posture with your feet shoulder-width apart (for the standing variation) or firmly planted on the ground (for the seated variation) to support your spine and ensure proper mechanics. - Control the Movement
Avoid rushing through the exercise. Control both the upward and downward phases of the press, keeping the movement slow and steady. This ensures you engage the shoulder muscles fully and avoid using momentum, which can reduce the effectiveness of the exercise and increase the risk of injury. - Keep Your Elbow Close to Your Body
During the press, your elbow should remain close to your torso and move in a straight line. This positioning allows for better shoulder engagement and reduces the risk of shoulder impingement. - Avoid Locking Your Elbow
When pressing the dumbbell overhead, avoid locking your elbow at the top of the movement. Keep a slight bend to reduce stress on the elbow joint and maintain tension in the shoulder muscles. - Breathe Correctly
Inhale as you lower the dumbbell back to your starting position and exhale as you press it overhead. Proper breathing helps you maintain control and provides better stability during the lift. - Balance Your Reps
Make sure to perform an equal number of repetitions on both arms to avoid further muscle imbalances. If one side is weaker, you can start with that side to ensure it’s worked thoroughly before fatigue sets in. - Use a Spotter for Heavy Weights
If you’re progressing to heavier weights, having a spotter can help ensure safety and prevent shoulder strain, especially if you experience fatigue during the lift. - Incorporate Stretching and Mobility Work
To enhance your range of motion and protect your shoulders, incorporate regular shoulder stretches and mobility exercises into your routine. This helps prevent stiffness and improves your overall form during the press.

Engaging these stabilizers helps build overall strength and balance, which is essential for athletic performance and injury prevention. - Adaptable for All Fitness Levels
The Single-Arm Palm-In Dumbbell Shoulder Press can be easily adjusted by using different weights or performing it seated, standing, or kneeling, making it suitable for beginners and advanced lifters alike.
Single-Arm Palm-In Dumbbell Shoulder Press Exercise Cons
- Requires Strong Core Stability
Since this exercise is performed with one arm, maintaining balance can be challenging, especially for those with a weaker core. Without proper core stability, the exercise may lead to poor form, reducing its effectiveness and increasing the risk of injury. - May Be Difficult for Beginners
The single-arm variation requires more coordination and balance than traditional bilateral shoulder presses. Beginners may struggle to maintain proper posture and control, making it harder to focus on shoulder strength development. - Limited Weight Progression
Compared to barbell or two-arm dumbbell shoulder presses, the single-arm version limits the amount of weight you can lift. This may hinder muscle growth or strength development for more advanced lifters who are looking to progress with heavier loads. - Potential for Overcompensation
If one side is significantly stronger than the other, there’s a tendency for lifters to overcompensate with their dominant side, leading to an imbalance in muscle development. This can be counterproductive if not addressed properly. - Increased Shoulder Fatigue
Performing this exercise one arm at a time can result in faster fatigue in the shoulders, particularly during higher-rep sets. This can limit the number of reps performed and may reduce the overall volume of the workout. - Risk of Lower Back Strain
Without proper core engagement, lifters may unintentionally arch their lower back to compensate for the load, which can lead to lower back strain. It’s essential to focus on maintaining a neutral spine throughout the movement to avoid injury. - Requires Proper Equipment and Space
Performing the Single-Arm Palm-In Dumbbell Shoulder Press, particularly in a standing or kneeling position, requires ample space for the movement. This might not always be practical in crowded gyms or small home workout spaces.
Single-Arm Palm-In Dumbbell Shoulder Press Exercise Frequently Asked Questions
How does the Single-Arm Palm-In Dumbbell Shoulder Press improve core strength?
Since you’re pressing with one arm, your body naturally tries to compensate by shifting weight, which forces your core to engage more intensely. This unilateral movement strengthens your abs and obliques as they work to stabilize your spine and maintain balance.
Is the Single-Arm Palm-In Dumbbell Shoulder Press safer for shoulder joints than the traditional shoulder press?
Yes, the neutral grip (palm-in) used in this exercise places less stress on the shoulder joint compared to the traditional overhead press. It allows for a more natural movement path, reducing the likelihood of shoulder impingement or discomfort, making it ideal for those with shoulder issues.
What’s the primary difference between the single-arm and two-arm shoulder press?
The primary difference lies in muscle activation and stability. The single-arm variation requires more core engagement for balance and works on correcting strength imbalances between the left and right shoulders. The two-arm press, on the other hand, allows for heavier weights but doesn’t provide the same unilateral benefits.
Can I perform the Single-Arm Palm-In Dumbbell Shoulder Press while seated?
Yes, the seated variation of this exercise is a great option for isolating the shoulders and reducing the need for lower body and core stabilization. However, standing or kneeling variations will engage more stabilizing muscles, giving a full-body workout feel.
Is the Single-Arm Palm-In Dumbbell Shoulder Press good for functional strength?
Absolutely. The movement mimics real-life scenarios, such as lifting or pressing objects with one hand, making it an effective exercise for improving functional strength. It enhances your ability to perform daily tasks and sports activities that involve pushing or lifting.
