If muscle cuts are your goal, immediately purchase the Pure Strength Series. Then, after 8 to 10 weeks of Pure Strength get the Slow and Heavy series. Do Slow and Heavy for 3 weeks, then back to Pure Strength.
While Power Hour is a great workout it mainly promotes muscle endurance.
If you already have MIS here is a suggestion as to a possible rotation with Pure Strength and MIS:
Day 1: Chest, Shoulders, Triceps from Pure Strength
Day 2: Strong Legs and Abs from Pure Strength
Day 3: Back and Biceps from Pure Strength
Day 4: Rest, no weight training
Day 5: MIS
Day 6: Rest, no weight training
Day 7: Begin rotation again.
Any day you have enough time throw in a cardio. Cathe said that if you want to increase muscle size keep cardio down to about 3 times a week. Also, include a bit more protein in your diet.
There are so many other possible rotations with Pure Strength and MIS. Search this website and you will find tons of great ideas.
I began Pure Strength last March and the above rotation is what I usually do. The results I have had are awesome. I have cuts in my arms, back muscle I can actually see and my chest (area between collarbone and breasts) muscles are incredible. As a matter of fact, when I was in the shower I felt the area right in front of the armpits and thought I had a lump. However, when I discovered a matching lump on the other side I realized this was muscle. Never even knew you could grow a muscle there. My tricep area no longer wobbles when I wave.
So, that is my formula for cuts.
