Most Americans walk only about 4,000 steps per day, a number far below what is needed to maintain optimal health. Fitness Experts such as Dan Go warn that consistently low daily activity can increase the risk of chronic diseases, impact mental health, and shorten life expectancy. Walking, a simple and accessible form of exercise, has proven benefits for both physical and cognitive well-being. As simple as taking a short stroll in the park for 10 minutes every day can clear the mind, and make a noticeable difference in how we feel. Fitness coach Dan Go shares steps count from 4,000-12,000 steps a day, and divides them based on their impact on health and longevity. He explains what happens to the body and the mind at each milestone achieved.
