a few months ago while doing C&J I started feeling a lot of "pressure" in my lower back region. During first few days it felt as if there was a "stick" in my lower spine not allowing my spine to bend back. With a lot of stretching the "pressure" went away. a few days ago I decided to try and C&J again. Worked my way up to around 70kg and suddenly felt a slight pinch in the same area.
I believe it is the case of spinal discs being "squeezed". This ocurred because I am a tall guy and often tall guys have got "curvy" backs. (I have s slight hump in my upper back). Currently I am trying to get myself in a more straight and neutral position, pushing my head forward and my shoulders backwards, "pulling inside" pelvic region when catching the bar, so that my spine would not be so bent. I wondered if any of you guys had a similar problem and how you dealt with it.This problem occurs only when I raise my arms up. I do back and front squats everyday and have no issues.
P.S. I don't have any problems when snatching, but that's because during snatch you catch the bar behind your head, whereas in C&J it's in the front. Thanks for any input.
