I just started training abs and while doing some incline board sit-ups, my mid abdominal region pops out like a balloon! It starts about 2 inches above my naval and runs for about 4-5 inches right in the middle of my abdomen. Very strange. Is this bad? What is causing this? I do have what is called a large amount of "visceral" fat...is that causing the abs to lie high on top of the fat? That area also cramps up a bit easy after only doing about 20 sit-ups or crunches...not sure if it's because the muscle is weak and out of shape or if I have some type of condition.
Any ideas on what this is?
