FITNESS AGE

This feature uses chronological age, your weekly vigorous activity and resting heart rate to estimate if your body is younger or older than you are. And you can get tips to lower your fitness age.

RECOVERY TIME

After each workout, recovery time lets you know when you’ll be ready for another hard workout. It even accounts for training intensity and factors such as stress, daily activity and sleep.

TRAINING STATUS

This metric evaluates your recent exercise history and performance indicators to let you know if you’re training productively, peaking or overreaching.

For training guidance that takes you and your fitness level into account, get daily run suggestions based on your current training load and status.

Track how you’re breathing throughout the day, during sleep, and during breathwork.

BODY BATTERY™ ENERGY MONITORING

Track your body’s energy levels so you can find the best times for activity and rest.

HYDRATION TRACKING

WRIST-BASED HEART RATE

The watch constantly samples your heart rate5 and will alert you if it stays too high or too low while you’re at rest. It also helps gauge how hard you work during activities — even while swimming.
