I do not like the whooping, and I remember when I first got the Intensity Series, it really bothered me. But now, I barely notice it. I've done them so many times! And also, I had to pay a lot more attention when I wasnt' as familiar with the workouts. Now, I am just heaving weight and jumping around like crazy and barely notice the whooping.
So, my point is, maybe as you get used to the workouts, it will get better for you too.
And I did notice, maybe due to the complaining on the forum, who knows, there is a LOT less whooping in the Body Blast series than there was on Intensities.
