The PS Series does 2 sets of either 10, 12 or 16 reps for the lower body. The rest between sets is short, usually just enough time to set the barbell down and swipe some sweat, then you're on to the next set. The longer reps are in the beginning when you do sets of lunges with dumbbells, but you do 1 set of 16 front lunges, then 1 set of 16 back lunges to equal your 2 sets. Then there are 2 sets of 16 rep static lunges. After that, there are I believe step ups which are 2 sets of 12 reps. After those, I believe everything else is in 2 sets of 10 reps.
And the floorwork section is like nothing mere words can describe! PS Series is a great series, and worth every dime for the whole set! Your body can only benefit from a second weight workout to rotate to, after it becomes too accustomed to MIS, you'll want to have a second workout to rotate to in order to continue to see results.
