For me personally, I felt the bench was kind of a tool to help with the form of the exercise. To help make sure you are really getting the butt down and back to get the proper form.
Also, since this is in the Warm Up section of the exercise I was treating it more of a cardio exercise and trying to get my heart rate up, and sweat a little. There is definitely a burn and fatigue when super setting this right after the other exercise. I was trying to do them at a nice pace, perfect form, and do them with as much energy and muscle explosion as I could.
I just treated them as a leg/body warm up before the real butt kicking exercises began. And boy did the rest of the workout get hard, lol.
Hope that helps a little.
