Garmin | Vivoactive 4S

Tune in to your body, and tone up with the smartwatch that can track it all and help you reach your health and fitness goals.

BODY BATTERY™ ENERGY MONITORING

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

PULSE OX SENSOR

The Pulse Ox sensor gauges your blood oxygen saturation during the day and as you sleep to show how well your body is absorbing oxygen.

STRESS TRACKING

Find out if you’re having a calm, balanced or stressful day. Relax reminders will even prompt you to do a short breathing activity when you’re feeling stressed.

HYDRATION TRACKING

Log your daily fluid intake as a reminder to stay hydrated. You can even have an auto goal for hydration that adjusts based on how much sweat you lose during activities.

WRIST-BASED HEART RATE

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

ADVANCED SLEEP MONITORING

Get a full picture of how you’re sleeping, with a breakdown of your light, deep and REM sleep stages as well as Pulse Ox¹ and respiration data.
