Hi guys, I'm Thiago from Italy. From the age of 22 I've always trained for maximal strenght with PL method but, in the last 3 mounths I've decided to add some simple calistenich movements into my training: pushup and pullup. I've a question about the shoulder and blades position in the pushup movement. Do I have to set them like in the bench press or do I have to take an hollow position!? About the hollow position, what is the difference between the position taken into the powerlift? Thanks, and sorry for my bad english.
