newbie at exercise, still obese.. question
I have no idea what kind of results you'd see. Since you haven't exercised in years, it'll be important for you to start slowly and build good habits and make exercise a part of your daily life. I train and race because that's how I stay motivated. We all have our own thing that keeps us going, though.
It is suggested that you do aerobic exercise that elevates your heart rate for a minimum of 30 minutes 5 days a week. You may not be able to do that at first, but will if you remain faithful to an exercise plan.
It often happens when you exercise more you have a greater appetite. You'll just have to be certain you're not eating more while you increase the caloric expenditure through exercise. Abdominal work can be done just about daily, but I would start with strength training 2 days a week at first.
