I've replaced treadmill walking with daily humping schlepping rucking with all my weight and all my gear - RNNR by Chris Abraham
When your body mass index (BMI) is over 30 and about a third of your body weight is fat (not bones, cartilage, connective tissue, or muscle), then simply the act of moving oneself around and about using only your own two feet is a serious workout. For the morbidly obese, walking is, indeed, working out.
