We're in the process of updating workouts based on more recent group feedback. Since 2019 and the large number of people who realized that fitness is too important to be left to chance we launched a refinement program internally that re-tested workouts for accessibility and broad effectiveness plus, as exercise science continues to advance, we also on occasion change the primary focus of a workout by substituting exercises to make it more effective or changing some exercises to give it a greater impact on the fitness aspect it is targeting. I haven't got the database with the ones we are updating handy right now so I will check but it is likely to be why it is not currently available.
