Instead of taking health and exercise tips for the Home Shopping Network and dropping your hard earned cash on devices that promise you a 6-pack by gently massaging your abs, invest in Larklife. Larklife is an app-powered wristband that will coach you in all things healthy. Not only does it track your exercise data and provide you with helpful feedback, but it also does so for your diet, your sleep schedule and helps you stay refreshed during the work day. Think of it like having a far less annoying Richard Simmons strapped to your wrist. The ergonomic day band is sweat-proof and comfortable, and the night one is unobtrusive enough that you can actually fall asleep with it on. It syncs with a simple press of a button and will help you change up that steady diet of Cheetos and beer (or at least counteract it).
