straight forward issue.
Id is an identity column, you cannot explicity insert identity value to the table directly,
You will have to set the IDENTITY_INSERT to ON to insert the id value.

SET IDENTITY_INSERT Workouts ON
 -- insert  the data 
INSERT INTO Workouts (Id, Name, Description) VALUES (1, 'HIIT', 'High-Intensity Interval Training')   
 SET IDENTITY_INSERT Workouts OFF
