Fifteen minutes of exercise is an excellent goal for me. I can do it, not I think I can do it. I have pushed myself to up to 25 minutes before. I usually exercise between 8:30-9:00 AM. My weight loss regimen is important for me to follow, especially since I have a hormonal condition. My health has become more important to me than ever. I wonder if I should make an exercise plan daily or by the week? How many days a week should I exercise? Those are the questions that I need to ask myself if I wish to become more fit and exercise.
