Running on the Treadmill
Why do my hands and fingers swell when I'm on the treadmill?

It's common for hands to swell, especially during longer workouts, but it's nothing to worry about, says Carl "Chip" Lavie, MD, director of the Exercise Laboratories at Ochsner Clinic Foundation in New Orleans. The puffiness is from blood pooling in your hands, which hang lower than your heart and are not engaged in muscular activity, says Dr. Lavie. If the swelling bothers you, he suggests doing some basic arm movements without weights (like biceps curls and triceps presses) as you walk.
