Theory behind 5X5
I started the Intermediate 5X5 routine and I was wondering what is the theory behind this routine? Im on week 2 right now. I plugged all my lifts into the spreadsheet and I know it just an estimate, but what is it about this routine that'll increase my max lifts so drastically? Why after week 4 should I be able to add weight every week to my lifts and succeed? Just wondering what about this training method will make me that much stronger.
