Can someone explain, in detail, what is "Cycling?"

It means different things to different people but essentially it's doing shorter p3s and p4s to get back to p2 a little quicker. Some people skip doing p4 all together and do a longer p3. It's not very cut and dry. I think it's important to at least do 3 weeks of p3. Your body does need the break and you also need the reshaping that happens in p3&p4.
