Traditionally a yoga exercise done on the floor, this Cobra Stretch has been adapted for the office. The exercise is designed to improve the flexibility of the abdominal and psoas muscles as well as increase mobility in the low back.
According to author Shirley Archer in "Fitness 9 to 5", "Spending a few extra minutes each day in your invisible chair tones up your abs, back, and thighs. Building more muscle mass boosts your metabolism for more calorie burn even while you sleep!"
Standing up to stretch can improve circulation (especially in your feet and legs) and relieve the neck and back stiffness that comes from prolonged sitting. It's important to get up regularly throughout the day!
