in daily competitive swimming
YES. That is one of the best ways. Your muscles will also get very toned.
I tried this and was not so successful. I read that cool water like in swimming pool actually causes your body to try to stay fat in order to keep warm. Ever seen a skinny whale? Still, it is very good exercise but maybe not the best for weight loss.
this is a great calorie burning exercise! just don,t eat more food, and you will lose.
You may not be able to loose weight, but you could lose some by swimming every day.
