Cardio burns more calories , so it's great for quick weight loss, but after that you have to include a few hours a week of strength training. When you can not do cardio, it is advisable to do strength training at least twice a week, working all your major muscle groups, and to walk at least 15,000 steps a day ( Use a pedometer to hold the account). http://getnutritionshelp.com/holistic-bliss-keto/
