Garmin Venu 3
GPS smartwatch built for sleep, recovery, and 24/7 health monitoring.
The Garmin Venu 3 pairs a bright AMOLED display with full-night sleep staging, nap tracking, and HRV status. Built-in GPS and a 14-day battery make it one of the most complete biometric platforms on the wrist.
Scientific Rationale
Continuous heart-rate, SpO2, and HRV monitoring correlate with cardiovascular fitness and recovery. Garmin's sleep staging provides nightly estimates of REM, deep, and light sleep tied to next-day readiness.
Daily Protocol
Wear continuously. Review morning sleep score and HRV trend. Use Body Battery to pace training intensity.
