I knew a short stocky SNCO who just struggled with crunches, no matter how much effort he put into them. I found crunches easy because I have long arms and a short torso, so the distance I had to travel to do a technically-correct crunch was minimal. But I've always struggled with pull-ups....because those same long arms make the pull-up distance feel like I'm free climbing the Dawn Wall.

I also think doing sit-ups in the Army on stupidly-hard surfaces (parking lots, etc...) before I switched to the Corps is one of the main sources of my lower back pain.
