Yes, I do. I don't only love taking walk but I see myself as addict of it. There's no single day I don't engage in it. And not just doing it as if it's a form of strolling but with the intention of exercising. Meaning that whenever I am walking I ensure that it's done briskly.
Apparently, the only substitute for my workout session is long distance brisk walking, which is serves as perfect physical activity for me, especially if I am unable to embark on regular exercise. Basically, exercise is one of my hobby which has become an indispensable activity to me. Honestly, I don't think I can survive a day without exercising, because I am aware of the benefits it offers to my general well being.
Apart from just staying fit, it has unique way of elevating my mood, and this in turn boosts my level of productivity as it increases my feel good hormones i.e, endorphines.
