Well I had a strange moment, after some heavy box squatting and hex bar deadlifting I wanted to hang on a bar to decompress my spine and after a couple of seconds of hanging and contracted my core while hanging and then relaxing and after jumping off I couldn't stand up straight without my back and deep core paining, like breath taking type of pain.
It's strange how that happened, I did cobra stretch which presented no pain but after standing pain came back especially when neutral spine, so after some sitting it got better.
Need to stop stretching my back when I hurt it.
