That isn't a routine posted, just a list of days and exercises. It may seem like a small thing, but knowing whether you're doing "3x5" of deadlifts versus "3x15" makes a huge difference in determining how effective your routine is.

Also hugely important, what is your goal? I get the sense from the HIIT work that you're looking to drop body fat... is this correct? What time frame are you working with? How does your diet play into your goal? etc, etc

You're going to be sore on almost any new program you start. It's just your body getting used to it. This is especially prevalent with squats making people sore.
