This push / pull / lower split is designed for really anyone, from beginner to advanced. It has a balanced approach of frequency and volume which makes it fit a multitude of goal sets. If you are coming from the 1/2 Body split, this PPL split is a seamless transition forward to the next step into advancing your training. Last 12 total weeks, the PPL split has and A & B workout for each given day. This means 6 different progressive workouts that increase in volume, intensity, and demand over the course of 3 different phases. Each of them lasting 4 weeks a piece. Whether you are wanting to build muscle, lose fat, or change body comp very quickly the PPL split is a very balanced and effective attack to do so. Personally, I think this is about as challenging as you can make a 12 week experience. Good luck and go push yourself.
