I swim an hour a day in my apartment building's swimming pool. On top of that I walk whenever I can sometimes it's an hour a day, often it's 3-4 hours a day, and I've tried to end all sedentary forms of entertainment (video games, movies, bars, restaurants) and replace them with activities such as hiking, disc golf, swimming, jogging, diving, even dancing (if you want to be humbled, go to a group Bhangra dance lesson, and observe how sore your shoulders are the next morning).
