About

"The exercises should be performed in rapid succession, allowing 30 seconds for each [with a 10-second rest between exercises], while, throughout, the intensity hovers at about an 8 on a discomfort scale of 1 to 10. Those seven minutes should be, in a word, unpleasant. The upside is, after seven minutes, you're done."
