Garmin Fitness Tracking Smartwatches

Training Readiness is a daily score focused on your ability to perform a workout, calculated from sleep quality, recovery time, and acute training load; Body Battery is a 24/7 energy level estimate based on heart rate variability, stress, and activity, reflecting your overall physical and mental reserves.

The Garmin Fenix and Instinct series are considered the most rugged, with the Fenix line offering premium materials like sapphire and titanium plus advanced mapping, while the Instinct series provides extreme durability and long battery life, often with solar charging options.

Users track their menstrual cycle or pregnancy by enabling the Women's Health feature in the Garmin Connect app, which allows them to log symptoms, view cycle/period predictions, and get health and nutrition insights directly on compatible watches like the Lily 2.

Garmin's Training Status is a long-term view of your training, determined by changes in your VO2 Max fitness level, your 7-day Acute Training Load, and your Heart Rate Variability Status, indicating if your training is productive, peaking, or overreaching.

A new Garmin device typically requires a learning period of 5 to 7 days of continuous wear to collect enough heart rate variability and stress data to establish a physiological baseline and provide accurate Body Battery readings.
