Yes, but most people have a shitty thoracic curve as it is. If you can do that and can get back to neutral right after and stay neutral, than sure go away at it.
Anyways, a week of doing PRI breathing stuff and ab work everyday has cleared up my back pain.
Since I can't do this powerlifting meet in NOV I'm going to pick up this strongman meet coming up. I've already practiced a lot of the movements earlier this year, just need to get my frame deadlift up.
