 ### 3.2. Workout Management (Plans)
+
+*   **3.1.5 Default Exercises (Seeding)**
+    *   **Concept**: New users are initialized with a set of default exercises.
+    *   **Configuration**:
+        *   The file path is defined by `DEFAULT_EXERCISES_CSV_PATH` in `.env`.
+        *   Format: CSV (`name`, `type`, `bodyWeightPercentage`, `isUnilateral`).
+    *   **Logic**:
+        *   Upon successful registration (3.1.2), the system reads the CSV.
+        *   It creates `Exercise` records in the DB linked to the new user.
+        *   Failure to read/parse the CSV is non-blocking (logs an error but allows user creation).
 Users can structure their training via Plans.
