Prolonged sitting at work can cause poor posture, low back pain, and increased risk for cardiovascular disease and diabetes. To combat the negative effects of long periods of sitting, the American Council on Exercise recommends the following: standing for a few minutes every hour; sitting on a gym ball for half an hour per day to activate your core muscles; participating in walking meetings; doing some wall push-ups, squats, and calf raises throughout the day; working out or taking a walk during your lunch hour; biking or walking to work; and practicing yoga or meditation to help reduce stress.
