when i do any activity I put on my waist trimmer belt. It helps with*losing all the water weight in that area. I also do crunches and leg lifts because they reaaaaaally works out the lower part of the abdomen. Just one thing, Dont push out your stomach when your are lifting your legs or your body up b/c it will cause your abdomen to protrude. Always contract your muscle when you are exhaling. Make sure to do a lot of twisting thingy!
