No, because it is soul that experience beatific vision/theosis after death. And when it will be reunited with our body it would be body so perfect that nothing could be add to it.
But to master sinful flesh is to make good steps towards it. Many people do not realise it but sportsmen pracitce virtue of mortification daily. Of course natural virtue won't take you far enough. And there is difrence between mastering one's body and crucifying it wth Christ. In a short run sure, sport help. But in the long run you have to practice at least some form of asceticism.
