Was hoping for some advice, my lower back just doesn't seem strong like it used to be. It's not necessarily in pain, but when I squat its gets so stiff i usually am not able to continue.
I don't think it's a form issue either, I've been lifting for close to 5 years and I am able to tolerate huge volumes; I used to squat and deadlift on the same day. Now after only 1 working set of deadlift or squat my lower back stiffs up and will feel like I worked out for 3 hrs. It's not pain though just real tense.
