Having a healthy mind is a wide subject to talk about I know as it is hard to distinguish having a healthy mind when we have clutters within us that are stopping us from thinking clearly. Having a healthy mind in my own opinion is connected to what attitude, on how we adapt to distractions.

Okay then, let me simplify this by, finding ways how we can think clearly. How can we think clearly? By training our brain which we can find the full article about it here: http://breakingmuscle.com/health-medicine/bdnf-basics-7-ways-to-train-your-brain
In my own personal experience, meditation plays a very important role after every exercise. It looks odd I know sitting inside the gym or outdoor after every exercise routine that I do but, I do not mind as it is for my wellness, my goal: a healthy mind and a healthy body.
