The code above executes properly. Although when the new week starts, it "randomizes" the exact same workouts as the previous week. Is there an issue with my code?

Example: Last Monday I had the EXACT SAME workouts as this Monday. Now I know that it can not be a coincidence. There must be an issue with the schedule portion of the program.
