We're taking over your health and fitness routine and teaching you how to use fitness trackers and apps to make the most of your workout. While Kabir swears by free apps (no surprises there!), Priyanka is tinkering with some hardware and will show you how to use the Fitbit Alta and Fitbit Blaze, two fitness trackers that are becoming popular among runners. And if you're looking for some cool apps to be a masterchef, we've got that covered too.
