Imagine if your Apple Watch could tell you which days were best for you to do a workout, and what kind of workout you should do. Well it can, sort of, thanks to a hidden feature that few people have yet discovered or know how to use.

Heart rate variability, or HRV, is a new metric that reveals your stress level and whether you have recovered from your last workout. It has been added to lots of high-end sports watches in recent years, including Apple Watch since watchOS 4 & iOS 11.

Here’s how you can use it to optimize your training, reduce your risk of injury, and know when to take a well-earned rest day.

If you think the Health app is just another pointless junk app that comes preinstalled on your iPhone, think again. Unlike Stocks, Compass or Tips, it is one of the few apps that Apple won’t let you delete. Set up the Apple Health app properly, and it becomes a powerful tool for getting (or staying) fit.

You see, the Health app lies at the heart of Cupertino’s growing health and fitness ambitions. And with its underlying HealthKit API, the Health app provides the framework that Apple Watch uses to gather data on your daily activity, heart rate and workouts.

But the Health app is more than just a place for storing data. With every iOS update, Apple makes major improvements to it. So, if you still think the Health app is a waste of space, it’s probably time you gave it another look. Especially if you own an Apple Watch. You’ll find it contains loads of useful, well-presented data that can help you achieve your fitness goals.

At WWDC this week, Apple all but confirmed that Apple Watch is really just a health gadget. Tim Cook described it offhandedly as a “device for a healthy life,” and most of the watchOS 3 segment of the keynote was devoted to health and fitness.

This focus on health makes sense. As an activity tracker, Apple Watch is arguably the best on the market, and watchOS 3 will make it even better. Apple’s wearable is ideal if you are simply looking to live a healthier day. But, despite some minor improvements, Apple Watch still sucks if you are into running.
