Strong evidence however shows that this doesn't mean that cells are actually «destroyed» or «
lost», but instead they are moved to other
parts of the body such as the
lungs which have more
of a chance
of becoming infected.
The reason why swimming is the best when it comes to
losing weight is that it exposes most
of your body muscles and therefore gives your heart and
lungs a better challenge to ensure that these
parts receive adequate oxygen.
