On this "abs" business, when I was in my 20s, and eating everything in sight, playing baseball nearly every evening consumed the calories adequately. But winters in the Chicago area? So, I started doing sit-ups, guess today they call them "crunches"? Boy, at first, nausea became a part of doing them, got used to that, it went away, within a month, I had progressed from doing 40 or 50 to 500 or more, so time consuming, and so little evidence of results! Flat belly, yes, "abs", not very evident. imp
