I remember when I was just a wee lad, and I began watching my belly grow a little larger than the other boys. My father declared that one sure remedy would be for me to do sit-ups. In fact, Dad had been the sit-up champion in high school and he was always proud about that fact.
So I guess the question is really about if and how sit-ups burn belly fat. The answer is that they do but only in a general metabolic sense. Abdominal crunches and sit-ups increase the strength and size and the depth of abdominal muscles over time, that is a fact. And any exercise, abdominals included increase your metabolism and increase the chances that some portion of fat is burned and reduced into energy for your body.
However, if you tend to keep fat on your midsection and think that sit-ups will do the fat vanishing trick then you’ll most likely be disappointed. Good nutrition and the resulting overall reduction in body fat percentage is what will expose your abdominal muscles.
The best six pack in the world, can be there and still be covered with enough fat to make it invisible. And most people have remarkable abdominal muscles under the fat layer. Correct diet and a propensity to eat dark green vegetables, low sugar fruits, lean fish and chicken and egg whites will help probably more than anything else to get that belly fat off the middle. And if you do a nice regular abdominal routine to boot, then you’ll have a nice six-pack when the body fat percentage gets down to about ten percent.
Do sit-ups burn belly fat? Kind of a little bit, but correct dedication to a nutrition regiment is more important.
