Hehehe...I always smile in unbelief when I read that exercise can help in addition and some other things. Maybe not for me as I do not see how this can be of help, to be honest. Fine, exercise is good for so many things, but for the things that have to do with people's minds and psychology, I think it can do little or nothing here. Gambling is beyond all that, especially when the gambler has now taken it as a hobby or is addicted to it, it takes more psychological functions and routines for this to be let go.
This is not about you seeing professional players doing it, there are a lot of reasons for that, and when it comes to regular people, even those who are consistent with exercise as what they like as a hobby are still addicted to gambling. What about that? I believe that they will link this to some kind of muscle relaxation and all that, but in practice, to cure anything mental is beyond that. If this is so true and cureable as they make people believe, I guess by now most of the people who are gambling with addiction would have been cured. It will even be easy.
Sports activities can increase self-relaxation and divert thoughts that focus on gambling. Basically, exercise focuses on fitness and health in physical conditions but also has an effect on psychological factors, although the benefits are not directly at the point of healing from gambling addiction. When you exercise discipline, you will feel changes in your health and relaxation which will help heal stress and your lifestyle will be more regular.
But I have to admit that exercise is not the point of curing gambling addiction, but at least some cases of gamblers who are addicted can be recovered by increasing outside activities such as exercise or other activities that are useful for calming the mind. However, complete recovery from gambling addiction depends on the will of the gambler and they must be disciplined in therapy.
