The flawed logic of 'holding' your shoulders
Many people are told to sit up straight and pull their shoulders back, but attempting to consciously hold this position all day is counterproductive. This approach creates static muscle tension in the upper back and neck, which can lead to fatigue, soreness, and pain. The back muscles are designed for movement, contracting and releasing to support motion, not for being held in a fixed, strenuous position for hours on end. This constant muscular effort is unsustainable; as soon as you stop thinking about it, your shoulders will revert to their comfortable, though potentially rounded, position.
The negative effects of constant tension
- Muscle Fatigue: Constantly contracting muscles deplete their energy stores, leading to premature fatigue and a reduced ability to support healthy movement.
- Co-Contraction and Stiffness: Forcing your shoulders back creates a 'tug of war' between your chest and back muscles. This co-contraction increases overall tension and can result in stiffness and a reduced range of motion.
- Impeded Breathing: A rigidly held-back chest can restrict the movement of your diaphragm, leading to shallower, less efficient breathing. Proper breathing requires 360-degree expansion of the ribcage, including the back.
The principle of neutral alignment
Proper posture isn't about rigid, forced positions but about achieving a balanced, neutral alignment that allows your skeleton to support your body with minimal muscular effort. When sitting, your goal should be to align your body so your ears are over your shoulders, your shoulders are over your hips, and your spine maintains its natural curves. Your shoulders should be relaxed, not rounded forward or forcefully pulled back.
How to achieve natural shoulder positioning
- Start with Your Foundation: Sit back fully in your chair with your feet flat on the floor and knees at a 90-degree angle. If your feet don't reach, use a footrest.
- Support Your Spine: Ensure your chair has good lower back support. Use a lumbar pillow or a rolled-up towel to maintain the natural inward curve of your lower back.
- Align Your Head: Keep your chin parallel to the floor, and your head balanced directly over your shoulders. Avoid craning your neck forward to look at a monitor.
- Relax and Widen: Allow your shoulders to relax and drop away from your ears. Imagine widening across your collarbones. Your shoulder blades should feel like they are gently resting on your curved ribcage, not squeezed together.
Ergonomic setup and environmental factors
An ergonomic workspace is crucial for maintaining good shoulder posture without conscious effort. Your environment should work for you, not against you. Adjusting your equipment can make a significant difference.
- Monitor Height: The top of your computer monitor should be at or slightly below eye level. This prevents you from tilting your head forward or backward, which puts strain on your neck and shoulders.
- Keyboard and Mouse: Keep your forearms parallel to the floor, with your elbows bent at 90-120 degrees. Your wrists should be in a neutral position, not bent up or down.
- Regular Movement: The best posture is the next posture. Set a timer to remind yourself to stand up, stretch, and move around every hour. This prevents your body from getting stuck in any one static position for too long.
Comparing holding vs. relaxed neutral posture
| Aspect | Holding Shoulders (Incorrect) | Relaxed Neutral (Correct) |
|---|---|---|
| Muscle Effort | High, constant, fatiguing | Low, sustainable, balanced |
| Long-Term Effect | Increased risk of pain, stiffness, strain | Reduced pain, improved mobility, better breathing |
| Breathing | Often restricted and shallow | Full, unrestricted 360-degree expansion |
| Overall Health | Can lead to muscle imbalance and injury | Promotes efficient movement and reduces fatigue |
| Skeletal Support | Relies on muscles to hold alignment | Uses skeletal structure to bear weight |
Simple exercises for better shoulder health
Incorporating simple stretches and exercises can help release tension and improve your natural alignment.
- Shoulder Rolls: Gently roll your shoulders up toward your ears, then back and down. Do 5–10 repetitions in each direction. This mobilizes the shoulder joint and releases tension.
- Scapular Retractions: Squeeze your shoulder blades together gently, as if holding a pen between them. Hold for 5–10 seconds and release. Repeat 5–10 times. This strengthens the muscles that support good alignment.
- Doorway Stretch: Stand in a doorway with your elbows bent at 90 degrees, forearms on the frame. Step forward with one foot and lean into the stretch until you feel a gentle pull across your chest. Hold for 30 seconds. This helps counter the forward-slouching posture common in desk work.
- Chin Tucks: Gently pull your head straight back, as if making a double chin, without looking down. This aligns your head with your spine and stretches the muscles at the back of your neck.
- Pendulum Swings: Lean forward, resting your non-stretching arm on a table. Let your other arm hang freely and swing it in small circles. This helps to relax the rotator cuff muscles.

Conclusion: The power of mindful relaxation
Rather than asking, "Should you hold your shoulders while sitting or left them freely?", a more helpful question is, "How can I create an environment that encourages relaxed, natural posture?" The key is to stop fighting gravity by consciously holding your body in place. Instead, focus on setting up your workspace ergonomically, supporting your spine, and taking regular movement breaks. By prioritizing neutral alignment and strengthening your core, you can train your body to maintain a healthy posture effortlessly, leading to less pain, more energy, and improved overall health.
