I really dislike the shred. Thought about quitting a lot. It hurts my knees, I get way too bored with it, but I am so glad I stuck with it. In 10 days I lost 7 lbs and a total of 10.75 inches total. I've done day 11 or day 1 of level 2 and its a killer, but at least its not boring yet. Good luck ladies.
