+    """Provides access to Fitbit Active Zone Minutes (AZM) API for heart rate-based activity metrics.
+
+    This resource handles endpoints for retrieving Active Zone Minutes (AZM) data, which measures
+    the time users spend in target heart rate zones during exercise or daily activities. AZM
+    is a scientifically-validated way to track activity intensity based on personalized heart
+    rate zones rather than just steps.
 
-    Active Zone Minutes (AZM) measure the time spent in target heart rate zones.
     Different zones contribute differently to the total AZM count:
-    - Fat Burn zone: 1 minute = 1 AZM
-    - Cardio zone: 1 minute = 2 AZM
-    - Peak zone: 1 minute = 2 AZM
+    - Fat Burn zone: 1 minute = 1 AZM (moderate intensity)
+    - Cardio zone: 1 minute = 2 AZM (high intensity)
+    - Peak zone: 1 minute = 2 AZM (maximum effort)

+
+    Required Scopes:
+        - activity (for all AZM endpoints)
+
+    Note:
+        - Heart rate zones are personalized based on the user's resting heart rate and age
+        - The American Heart Association recommends 150 minutes of moderate (Fat Burn) or
+          75 minutes of vigorous (Cardio/Peak) activity per week
+        - AZM data is available from the date the user first set up their Fitbit device
+        - Historical data older than 3 years may not be available through the API
+        - Not all Fitbit devices support AZM tracking (requires heart rate monitoring)
+        - The date range endpoints are useful for analyzing weekly and monthly AZM totals
