anyone have good excercises for lower abs? i havne't had a six pack since my wrestling days in high school, and i started seriously working on abs and now, it starts to show up even at 12% bodyfat. however, i only see the top 4, and when i feel around, the lower ab muscles are much smaller! currently, i do weighted crunches on a decline bench, which seem to help the upper 4 abs, and im trying out leg raises on a bench (lying down) w/ weights to try to target the lower ab muscles. any good excercises recommended for targeting thne lower abs? i think my upper abs are alright for now.
