This question is about belt use. I am on week 4 of the 1.1. For most of my 5/3/1 experience(4 cycles) I have only used a belt for the PR sets and jokers. I do notice a huge difference for me between belt and no belt. I also notice that my lower back gets really tight when I don't use a belt..
So for doing the 1.1, I did what Jim recommends in the intro, we can use a belt for everything but the 5x5(or 5x3 for DLs). What I noticed was that using the belt for all 3 5/3/1 sets, my lower back feels great. But doing the 5x5s with 1 min rest and no belt.. I can hardly bear the lower back tightness.
Getting to the point here.. Can anyone tell me what this relationship between wearing a belt and lower back tightness means? Do I need more core work? Am I bracing wrong, perhaps? I hate to use the belt as a crutch but it makes my lower back really happy lol. And lower back tightness has been a major issue for me with past back problems..
