You don't need 10,000 steps per day to reduce your risk of death or major diseases (but it might be best). A new study finds that benefits begin to accrue at 4,000 steps per day, with a 9-39% reduction in the risk for all-cause, CVD, and cancer mortality; dementia, and even depressive symptoms. 7,000 steps per day provided even greater benefits, reducing the risk of these outcomes by 22-47%. However, 10-12,000 steps per day was associated with a 30-55% risk reduction, benefits that were particularly apparent for all-cause and CVD mortality. What's my take here? Any and all movement is beneficial. But adding more steps to your day - regardless of where you're at - is never a bad idea.
