Is working out a way to run from your problems?
It isn't for me, but I think depending on the nature of the problem, it's possible to misuse the workout in such a way. It is clear that if you train with one big future goal in mind, you can become really obsessive about it because it is easy to structure your entire day around that and finally forget everything else that should matter, at least for a while and if you want to and are the type for that. Personally, I rather see that as a danger, than a benefit because problems you run away from, will come back to haunt you.
Although likely not entirely unrelated, the healthier way seems to be to use training to clear your mind regularly and to enjoy the many good effects of the positive stress (Eustress - Wikipedia) it gives, instead of the negative one we otherwise are exposed to too often.
Thanks for asking, Pooria Arab
