Features and everyday benefits
-
Plan training around recovery: Training readiness brings recovery information into your workout planning, helping you decide when to push harder and when an easier session may be more appropriate.
-
Understand recovery trends: Overnight heart rate variability adds context to your recovery. Reviewing the trend over time can help you see how your body responds to training and daily demands.
-
Follow your energy through the day: Body Battery estimates your available energy using supported health data. It provides a useful way to balance activity with rest and notice patterns in your daily routine.
-
Review your overnight rest: Sleep insights help you look beyond time in bed and review your overnight rest. Following your results across several nights makes longer-term patterns easier to spot.
-
Allow time between demanding sessions: Recovery-time guidance helps you consider how much rest to allow after exercise before another hard session, making it easier to plan a balanced week.
-
Notice busy and restful periods: Stress tracking gives you another view of your day, helping you recognise periods of higher demand and consider where a pause or calmer routine may help.
-
Designed for regular cleaning: The washable band or strap supports routine care after regular use. Remove the electronic module before washing and follow Garmin’s cleaning instructions.
-
Track overnight temperature trends: Skin-temperature trends add context to overnight data. They are most useful when reviewed alongside your usual sleep routine and other supported wellness information.
-
A gentler start to the morning: The smart wake alarm uses a vibration to wake you within your chosen wake window, bringing a sleep-focused approach to your morning routine.
