I've lost fifty pounds doing predominately Cathe, no gym involved. I walk half an hour before breakfast every day, do cardio DVDs two or three afternoons a week, and weightlifting DVDs two or three afternoons a week. My husband and I also have bicycles, and we take those out as schedules and weather permit. The main thing to remember is calorie intake; in spite of all the working out I was doing I didn't start dropping fat until I reduced my calories to about 1300-1400 a day. Summing up: on a diet of raw veggies, fresh fruit, lowfat and fat free dairy, and lean meat, while doing Cathe almost every day, I lost fifty pounds in eight months. Good luck!
