Nine Gadgets That Can Supercharge Your Workouts

1. The Timex Health Tracker ($65; www.timex.com)

Why we like it: Designed specifically for women looking to lose a few pounds, or, just boost their daily activity, the Timex Health Tracker has a built-in “workout mode” that automatically records how many steps you’ve walked, how far you’ve gone distance-wise, and how many calories you’re burning as you go, simply by sensing the swinging motion of your arm—it even beeps you when you’ve reached the half-way mark of your fitness goal for the day. But what we really love is that it also lets you secretly enter and record how many calories you’re eating during the day—without anyone else knowing what you’re doing.
