I say these types of applications of AR (Augmented Reality), "the wonders of the modern times".

Self training is not something surprising, but with the help of AR, we have definitely come to an advanced level of learning ... and what is that? ... For example if we consider the current hunt, which is about the training of ice hockey ... Not every player, who wants to join the ice hockey, has the availability of ice field to work/practice on.

Many AR training solutions are available for many sports and I hope, these solutions would keep coming/surfacing for other games too, like cricket, football etc, which need open fields for the practice.
