Back pumps!
I have the most debilitating back pumps known to man kind. I pretty much give up on working lower back because its impossible. It's pretty damn bad when you have to sit on your knees for 3-4 minutes just to relieve the pain in between sets.
This never happens to me unless i'm on cycle which is hilarious because that's when you really feel like tearing some shit up. It's just too much to handle, standing or sitting does nothing. he only thing I have found that helps is sitting on my knees like a jackass in the middle of the weight room floor. FML!
I know i'm not the only one to have met Mr. Backpump. Any ways to combat this?
