Philosophy

Do low impact cardio 7x per week. Swim whenever possible, and if you live by the beach, take advantage of that fact. Bike on Sundays for a very long distance. You might do 15+ miles on trails, 20 miles on the road, or even 40+ miles on the road if you can handle it. Drink plenty of water. If you have dogs, take them for brisk walks everyday to benefit yourself and the dogs, or just walk by yourself.

Walks are ideal for obese people to start out with, but people who are in better shape than that should try running to begin with, and progressively increase speed, distance, and duration.
