I was doing gm's the other day and kept my back as arched as possible but still felt some pain in my lower back (lumbar spine area). So just out of curiosity I tried not keeping my back as tightly arched. I still kept it straight, but just didnt tighten up my lower back as much. I felt ALOT less pressure on my lower back and ended up setting a 40 lb pr. Has anyone ever heard of anything like this? Is it safe for me to keep doing this as long as i dont let my back round over?
