Query: Very hard and repetitive

I've been doing Jillian Michaels' 30 minute workouts and recently tried this one. I've not even been able to make it through the first (and easiest) of the workouts and feel completely discouraged. This workout is MUCH harder and is filled with repetitive jumping. Other than for the intro, which in my opinion is the most enjoyable segment, the step I purchased is not even required for the 30/30 workout. I don't know how the other reviewers can claim the 30 minutes flew by. For me, it was the longest 30 minutes of my life. Not only is the difficulty level very high, but the moves are repetitive and boring. Jump and squat to the left for 30 seconds followed by jump and squat to the right for 30 seconds etc....YIKES. I'll stick with Jillian.
