Why Sitting Is Harder on Your Body Than You Think
Static posture — holding any position for a prolonged period — is mechanically demanding. Unlike moving, which distributes load across tissues, sustained posture requires specific muscles to maintain continuous contraction for hours. These muscles become fatigued, develop metabolic waste accumulation, reduce blood flow and progressively sensitise — becoming painful with less and less provocation.
The irony of desk work is that the muscles doing the most work are tiny postural muscles in the neck and upper back that most people don't think of as working at all. Meanwhile, the large muscles that are supposed to stabilise and move the body — the glutes, deep abdominals, thoracic extensors — switch off during sustained sitting, becoming inhibited and weak.
The combination — overactive postural muscles and inhibited global stabilisers — produces the characteristic pain pattern of desk workers: neck aching, tight shoulders, headaches, tension across the upper back, and lower back pain that arrives by mid-afternoon and is worst by the drive home.
The Muscles Most Affected by Desk Work
Upper trapezius and levator scapulae
These muscles connect the neck and upper back to the shoulder blade. In desk workers, they work continuously to support the weight of the head (around 5 kg) as it drifts forward towards the screen. Prolonged contraction produces the characteristic aching tension across the top of the shoulders that desk workers recognise immediately. Trigger points in these muscles commonly produce headaches at the side and base of the skull.
Suboccipital muscles
These four small muscles at the base of the skull control fine head movements and proprioception. In forward-head posture — the norm for screen users — they are held in sustained compression. This produces tension headaches, reduced cervical rotation, and can contribute to visual disturbances and dizziness in severe cases. They are highly responsive to specific soft tissue release.
Pectorals (chest muscles)
Hours of keyboard and mouse work with arms forward shortens the pectoral muscles, which progressively pull the shoulders forward and internally rotate the arms. This rounded shoulder posture is not primarily a habit — it's a physiological adaptation to the position you hold for most of your waking hours. Releasing tight pectorals is a key part of restoring good shoulder alignment.
Hip flexors (psoas, iliacus, rectus femoris)
Prolonged sitting shortens the hip flexors — the muscles that flex the hip joint. Shortened hip flexors tilt the pelvis forward (anterior pelvic tilt), which increases lumbar lordosis (the lower back curve) and loads the facet joints and discs. Many cases of desk worker lower back pain have tight hip flexors as a primary contributor. These are often neglected in self-treatment because they're hard to stretch effectively without guidance.
Forearm flexors and extensors
Hours of mouse and keyboard use loads the forearm muscles repeatedly with small forces. Over time, this produces tension in the forearm flexors and extensors, can develop into tendinopathy at the elbow (lateral epicondylitis/tennis elbow is common in heavy computer users) and contributes to carpal tunnel syndrome in some individuals. Regular forearm massage maintains tissue quality and reduces cumulative overload.
Desk work doesn't have to mean pain
Our sports massage therapists understand exactly what desk work does to the body — and exactly how to address it. Evening and Saturday appointments available in Surbiton.

A sports massage session for a desk worker follows a predictable pattern because the problem pattern is predictable. Your therapist will typically assess your posture and areas of restriction first, then work through:
- Upper trapezius and levator scapulae: Sustained pressure, trigger point release and cross-fibre work to reduce the accumulated tension in the muscles most chronically overloaded by head-forward posture
- Suboccipital release: Specific, gentle release at the base of the skull — often producing dramatic relief from headaches and neck stiffness
- Rhomboids and mid-trapezius: The muscles between the shoulder blades, often tender and inhibited in people with protracted shoulders
- Pectoral release: Gentle work to the chest muscles to counteract the rounding effect of prolonged forward arm position
- Lower back and gluteals: For those with lower back pain, work through the erector spinae, quadratus lumborum and gluteal complex
- Hip flexors: Where lower back pain is driven by hip flexor tightness, targeted work in the hip flexor region
A 60-minute session covers the upper body thoroughly. A 75–90-minute session allows full upper and lower body treatment — recommended if you experience both neck/shoulder problems and lower back or hip pain.
What to Combine with Massage for Best Results
Sports massage relieves tension effectively — but the desk work continues. Without addressing the underlying load, tension will rebuild. For lasting improvement, massage works best combined with: regular movement breaks during the working day (standing or moving every 30–45 minutes), targeted stretches for the specific areas you carry tension, strengthening exercises for the muscles that are inhibited (typically deep neck flexors, mid-back, glutes and deep abdominals), and workstation ergonomics optimisation.
Where pain has become significant or persistent, a physiotherapy assessment is appropriate to identify any structural issues and prescribe a specific rehabilitation programme. Our physiotherapists and sports massage therapists work as part of the same team at Lambert Sports Clinic, making this transition seamless.
