Seems like I'm having a bit of bad luck lately.
The title says it all, I always get the pain when coming down from back swing, just a moment before going through vertical hang position, so it has something to do with straightening the arch in my back while going to front swing.
The pain is in lumbar spine somewhere above the first vertebrae, but it isnt in the spine, it hurts a bit more to the right, I can reacreate the pain by doing lateral trunk lean to the left, that means my left shoudler drops, that's when it hurts. Lateral trunk lean to the right is absolutely pain free.
I'd be grateful if anyone knows what I may be doing wrong or if I have a weak link of some kind. Thanks.
