Book excerpt: OFFICE YOGA is a survival handbook for the deskbound; a practical manual of simple movements which you can do a few minutes at a time throughout the day, to relieve the tension and stress of sedentary working life. It gives clear instructions and illustrations for sixty stretching and breathing exercises--simple, safe, and fun to do--most of which can be done sitting in your chair at your desk. Office Yoga will make you feel better. It will relieve and help prevent headache, neck-ache, backache, and eye-ache. It will improve your posture and breathing, replenish your vitality, boost your energy levels and improve your concentration. Office Yoga also offers guidance on improving your personal working environment: chair, desk and lighting; and suggests how to make use of the time you spend travelling to and from work. If you work at a desk, computer terminal or drawing board, in an office or at home, Office Yoga will be of sound, practical help to you.
