The Apple Watch Series 4 has been out for less than a month and it’s already predicted to outsell its predecessor the Series 3.

That said, attempting to hit the gym as soon as you unbox the wearable might disappoint many consumers. Fitting useful tech into such a small package requires personalization, and hence, most new Apple Watch features have to be turned on or downloaded before you can start using them in earnest.

In particular, this latest iteration of the Apple Watch has taken a turn into the consumer health market, introducing electrocardiogram tech, a fall detection system, and the Livesum app that encourages healthy eating habits. But before you hit the treadmill, you’re going to have to swipe and tap through the wearable to make sure it’s fully personalized and ready to take your workouts to the next level.

The Activity app is has been a key feature to the Apple Watch since the smartwatch’s first version. And with Series 4 you can now see your friends’ Activity rings and compete to be the most active. This new feature will notify you every time one of your friends completes their daily activity goal to try to motivate you to sit less and move more.

2. Apple Watch Series 4: Lifesum Fitness App Update

The Lifesum app on WatchOS was advertised to users as being able to keep track of their daily caloric intake and water consumption right from their wrist, but none of data is available if you don’t update the app to its newest version.

4. Apple Watch Series 4: Turn On Fall Detection

Built-in fall detection was another one of the Apple Watch’s most touted features, but if you aren’t at least 65-years-old the system is turned off by default. While this feature might appeal to an older demographic, people partaking in sports like free-base climbing, gymnastics, or horse riding might want to a turn on fall detection just to play it safe.

Open the Apple Watch app on your handset and tap the My Watch tab at the bottom-left corner. Open the Emergency SOS menu and then switch the Fall Detection on.

Don’t worry about accidentally calling emergency services. Fall detection actively looks for two things, a “significant, hard fall” and immobility. So if it say, dive into bed and keep moving around the Series 4 will be able to tell you aren’t hurt. But if you fall and don’t move for a minute, it will begin a 15-second countdown to alert paramedics and your emergency contact of your location.
