Most of my energy is exerted through running. I run as a form of meditation, when I run I must focus on my breathing, I must focus on my form, and I am concentrating on getting to my destination. With my mind focused on these three things, everything else I may have been worried about leaves my mind, any anxiety I may have had is gone, and I am “free.”
I started running to be active and for health reasons, then I discovered it has therapeutic value for me. I also do general calisthenics to make sure my body is tone.
I suppose you have to factor in all the ways I benefit. I probably run too much by most peoples standards, and use too much energy in doing so. However, when factoring in my mental health - I don’t think the benefit outweighs the cost.
