Health and wellness Garmin features explained
Core health sensors and daily wellness tools
Pulse Ox / SpO₂
Pulse oximetry estimates blood oxygen saturation from the wrist. It is often used for wellness, sleep, and altitude acclimation trends rather than as a medical diagnostic tool.
Body Battery™
A Garmin energy score that combines stress, sleep, recovery, and activity signals to show how recharged or drained you may be during the day.
Stress tracking
Uses heart rate variability patterns to estimate whether your body is showing signs of calm, balanced, or elevated stress during the day.
Sleep tracking + sleep stages
Tracks overnight sleep length and usually breaks it into light, deep, and REM stages, along with wake periods, to provide a broader recovery picture.
Sleep Score
A simplified nightly score that rolls sleep duration, sleep stage balance, stress, and other overnight signals into one easier-to-read number.
Advanced sleep analytics
Garmin’s more detailed sleep review, typically including sleep score context, overnight recovery indicators, and expanded trend visibility on compatible newer models.
Nap detection
Automatically recognizes short daytime sleep sessions and factors them into your overall recovery picture on supported models.
HRV Status
Tracks overnight heart rate variability and compares it to your established personal baseline. It is widely used as a recovery and readiness indicator in Garmin’s ecosystem.
Health Snapshot™
A short guided session that collects several wellness readings together, such as heart rate, HRV, stress, respiration, and Pulse Ox, for a quick check-in.
Skin temperature
Measures wrist skin temperature trends during sleep. The value is more useful as a baseline deviation trend than as a stand-alone body temperature reading.
Morning Report
A wake-up summary on supported Garmin watches that can combine sleep, HRV status, weather, calendar, recovery, and suggested training information.
Women’s health and accessibility features
Menstrual cycle tracking
Lets users log cycle details and symptoms to view patterns, reminders, and related wellness context in Garmin Connect.
Pregnancy tracking
Supports pregnancy-related logging and wellness context in Garmin Connect for users who want to track changes over time.
Wheelchair mode
On compatible models, replaces step-oriented metrics with push-related activity tracking for users who use a wheelchair.
ECG app
On select compatible watches, Garmin’s ECG app can record a single-lead electrocardiogram session and check for signs of atrial fibrillation. Availability depends on the model and region.
Training and performance Garmin features explained
Readiness, load, and workout guidance
Training Readiness
A daily readiness score that combines several recovery and strain inputs, often including sleep, HRV status, recent training load, and recovery factors.
Training Load
Garmin’s estimate of how much overall workout stress you have accumulated recently. It helps show whether you are doing too little, enough, or too much.
Training Load Focus
Breaks recent training into categories, such as aerobic and anaerobic emphasis, so you can see whether your workload is balanced for your goals.
Recovery Time
Estimates how long your body may need before another hard effort based on the stress of your most recent workout and related readiness data.
Daily Suggested Workouts
Garmin’s on-watch workout recommendations that adapt to your recent fitness, training status, and recovery on supported running and cycling watches.
VO₂ Max estimate
An estimate of aerobic fitness based on exercise performance and heart rate data. Garmin uses it as one of several inputs for performance features.
Fitness Age
A simplified wellness metric that translates activity and cardiovascular fitness trends into an easier-to-understand “fitness age” style score.
Race Predictor
Uses recent fitness trends and training data to estimate potential race times for common distances on supported running watches.
Endurance Score
A long-term indicator intended to reflect your ability to sustain extended efforts over time, rather than only short, intense performance.
Hill Score
Designed to reflect uphill running ability by combining climbing-related performance with broader endurance information on compatible watches.
Lactate Threshold
An estimate of the exercise intensity where lactate begins to accumulate faster. This helps serious runners and cyclists train by more precise zones.
Training Status
Garmin’s broader interpretation of whether your current training pattern appears productive, maintaining, strained, or otherwise trending in a useful direction.
Running and multisport Garmin features explained
Running metrics and race tools
Running Power
Estimates your running output in watts, giving runners another way to pace effort beyond heart rate or pace alone. Availability varies by model.
Running Dynamics
Advanced form metrics such as cadence, ground contact time, stride length, vertical oscillation, and related measurements on compatible setups.
PacePro™
Provides pacing guidance that can account for route elevation changes so you can manage effort more strategically over a course.
ClimbPro
Shows climb-by-climb information, including grade and remaining ascent, during supported navigated routes so you can pace hills more intelligently.
Race widget / race calendar tools
Some Garmin running watches let users build toward a target event with countdowns, adaptive guidance, and race-day prep tools.
Track Run mode
Improves workout tracking on a standard running track by matching lap and lane behavior more intelligently than generic GPS activity mode.
Triathlon / multisport mode
Lets you combine swim, bike, and run or other back-to-back disciplines into one activity file, making transitions and total race tracking easier.
Open-water swim
Tracks distance and related metrics for swimming in lakes, oceans, and other open water environments rather than a pool.
Pool swim metrics
Records lap counts, lengths, stroke information, and related swim data for pool workouts when the pool length is configured correctly.
Cycling power support
Pairs with compatible cycling power meters to display watt-based cycling performance on watches that support more advanced bike training.

Garmin golf features explained
Course data, caddie tools, and golf tracking
Preloaded golf courses
Approach watches come with large course databases so you can access course layouts and yardages without loading each course manually.
Front / middle / back yardage
Shows distance to the front, center, and back of the green, which is the core daily-use golf GPS function.
Hazard and layup distances
Displays distances to bunkers, water, and layup points so you can manage shots more strategically.
Green view / aerial green view

Dogleg and layup view
Helps users understand the shape of the hole and plan safer or more aggressive tee and approach strategies.
PlaysLike Distance
Adjusts raw yardage to reflect slope and similar course conditions, helping golfers choose clubs based on effective distance rather than flat distance alone.
Virtual Caddie
Garmin describes this as club recommendation guidance based on the hole, wind data, and your past performance, after enough round data has been collected. On supported setups it can rely on CT10 tracking or club prompts.
Auto shot detection
Automatically identifies shots during play on compatible golf watches so round tracking takes less manual input.
Shot distance measurement
Uses GPS positions to estimate how far a shot traveled so golfers can better understand real on-course distances.
Stat tracking
