I like walking. It's really convenient and no fancy equipment is required. You can do it anywhere, anytime. It's also good for my heart and can somehow untangle the chaotic mess that is my brain. It's meditative, allowing my thoughts to flow freely and my anxieties to melt away. Whether it's a short stroll through your neighborhood or a long vigorous hike in the countryside, this TED-Ed video explains why walking is lauded as a cure for everything from boredom to slightly-too-tight jeans.
