Exercises for office workers — undo the 8-hour-sitting load

The 2016 Ekelund meta-analysis in The Lancet established sitting time as an independent mortality risk factor — more than 8 hours per day of sitting raises mortality by 60-100% in the sedentary subset. Critically, the same paper showed that 60-75 minutes per day of moderate activity OFFSETS the risk in the active subset. The 2017 Diaz study added the breakup rule: stand and move for 2-3 minutes every 30 minutes of sitting. The mechanism of sitting-driven harm is multifactorial: forward-head + thoracic kyphosis postural patterns (drive neck and shoulder pain), glute atrophy from chronic sitting (drives low back pain and reduced power), hip flexor tightness (drives anterior pelvic tilt and low back pain), median nerve compression at the wrist (drives carpal tunnel risk), reduced blood flow and lipid clearance (the metabolic mechanism). Specific countermeasures address each.

Volya's catalogue carries the office-worker-specific moves: scapular-retraction and wall-slide-scapular for upper-back postural reset (the most cost-effective intervention — 30 seconds an hour), median-nerve-glide for proactive carpal tunnel risk reduction, ninety-ninety-hip-stretch for hip capsule mobility, supported-glute-bridge for glute reactivation, standing-march for the breakup-the-sitting rule, diaphragmatic-breathing for autonomic regulation under chronic stress, cat-cow for spinal mobility. The AI coach also knows the nutrition side — Mediterranean / DASH pattern, consistent meal timing (broken by erratic schedules), limit ultra-processed desk snacks, hydration with water-bottle-on-desk default, caffeine after noon avoidance, protein-forward breakfast 20-30 g for sustained focus, fibre 25-35 g/day, vitamin D test-first (indoor workers near-universally low). This is prevention, not treatment — if you have established conditions (neck pain, sciatica, carpal tunnel symptoms), see the specific landing pages.
