Running gets all the glory. But walking may be the unsung hero of health. Research shows brisk walking lowers risk of heart disease almost as much as running, with fewer injuries. It’s easier on your joints, and you don’t need special shoes or a perfect track. I tested replacing my short runs with daily 30-minute walks. At first, I felt guilty—like it wasn’t “real exercise.” But within a month, I lost 3 pounds, my knees stopped hurting, and I actually looked forward to moving. Walking is sustainable. You can do it at any age, anywhere. Sometimes the simplest habit is the most powerful. #SimpleHealth #WalkingPower #LongevityHacks
