In 2025, Garmin revolutionized personal training with the launch of the Garmin Fitness Coach. Specifically optimized for the Venu 4, Fenix 8, and other top-tier wearables, this system moves beyond simple race-day training. It is a data-driven, adaptive platform designed to help you “Improve Fitness” on your own terms, combining cardio, strength, and real-time health insights.
Here is a unique and comprehensive look at the feature, along with guidance on how to integrate it into your routine.
The Core Philosophy: Training on Your Own Terms
Garmin Fitness Coach is built on the principle that life is unpredictable. Unlike traditional plans that follow a fixed calendar, this coach is completely adaptive. If you decide to skip a scheduled run to play tennis or go for a hike, the Fenix 8 detects that activity and recalculates your plan immediately. It removes the guesswork by telling you exactly when to push your limits and when your body needs to prioritize recovery, ensuring a healthy balance between effort and rest.
Heart Rate-Based Cardio Specializations
The Fitness Coach offers structured cardio workouts that are tailored to your fitness level. Rather than prescribing a set speed, it uses heart rate-based intensity to ensure you are training efficiently. The plans focus on several key outcomes:
-
Basic Endurance: These are the foundation of your plan, focusing on moderate intensity to build aerobic stamina and metabolic efficiency.
-
Cardio Fitness: Labeled as “comfortably hard,” these sessions focus on sustainable efforts that challenge your pacing and fat-burning capabilities.
-
VO2 Max Boost: High-intensity interval training (HIIT) sessions designed to push the upper limits of your aerobic capacity.
-
Cardio Capacity: Intense intervals designed to boost your performance near your lactate threshold.
-
Recovery Workouts: Low-intensity sessions that promote blood flow and muscle repair, often prescribed after a tough week or a night of poor sleep.
Integrated Strength Coaching
A standout feature of the Fitness Coach is its ability to blend cardiovascular health with muscle conditioning. During setup, you can opt to include up to two strength sessions per week.
-
Bodyweight or Gym: You can choose between equipment-free bodyweight routines or full gym workouts using dumbbells, kettlebells, squat racks, and cable machines.
-
Targeted Focus: The plan alternates between full-body conditioning and core stability, ensuring that your physical foundation supports your cardio goals.
How to Get and Use the Fitness Coach in Fenix 8
In December 2025, Garmin released a major update for the Fenix 8 series through Beta version 21.12, which finally brings the Garmin Fitness Coach to its premium adventure watch lineup. This update bridges the gap between high-end multisport tracking and personalized, daily health coaching. To get started, follow these steps:
-
Open Garmin Connect: Navigate to the Training & Planning menu and select Garmin Coach.
-
Select “Improve Fitness”: This is the specific path for the Fitness Coach. Do not select the 5K or Marathon race plans if you want the adaptive fitness experience.
-
Onboarding Questionnaire: The app will ask about your fitness history, goals, and preferred equipment. The AI uses this data to tailor your initial sessions.
Activity Flexibility: 26 Supported Profiles
You aren’t locked into running to satisfy your coach. The Garmin Fitness Coach supports 26 different activity profiles. If your plan calls for a “Basic Endurance” session, you can complete it via a brisk walk, an elliptical session, or a light jog. The Fenix 8 will monitor your heart rate throughout the activity to ensure it meets the coach’s requirements. If your chosen activity isn’t intense enough to hit the target, the watch will provide real-time guidance to help you adjust your effort.
