Anyone have any brutal, inhumane, painful ab exercises? I want something that kills me in like 20 reps instead of doing different kinds of crunches all day long. About the worst I have are:
"Morning Glories", where you do a combo crunch/leg lift
Some crazy Korean military exercise where you start on your back on the floor legs straight up and keeping your back flat and legs straight take your legs down to the left side, center, right side center (1)...
I also want a nice lookin six pack for the ladies

. I have basically no fat on me so i have a small one, but I guess I need to build strength to make the bottles pop out. I have 2 30 lb dumbells with me. So any suggestions?
