Unlike bulky and almost always noisy treadmills, the best walking pads are slim (often portable) machines that can slide under your standing desk or fit anywhere in your home, letting you rack up steps while working, binge-watching, or just avoiding human interaction. Sitting at your desk all day is literally a pain. It’s terrible for your posture and takes a toll on your physical and mental health, gradually morphing you into a hunched-over keyboard gargoyle. Theoretically, you could take walking breaks away from your screen, but even then, you’re still spending a lot of the day on your butt.
