+    TestTC003 is a test case class designed to validate the creation and management of workouts and their associated exercise instances in the API. It focusses on the creation of workouts with possible illegal data, such as negative sets.
+
+    This test case includes:
+    - Validation of creating a workout with valid data (`test_create_workout_valid`).
+    - Validation of adding an exercise instance to a workout with proper details.
+    - Testing error handling when invalid data is provided, such as negative sets (`test_create_workout_invalid_date`).
+
+    The tests ensure that the API correctly handles workout creation, exercise instance association, and validation of input data.
