Your attitude, thoughts and beliefs about exercise affect how well your body will respond to physical activity. If you hate exercise, chances are your motivation will be lacking and you will not experience the positive effects of exercise. If you love exercise, your motivation will be plentiful and you will accrue the many benefits of exercise. There may be particular exercises that you do not find enjoyable. If this is the case, simply stop performing the movements and try something that is enjoyable. You'll most likely stick with exercises you enjoy.
BOTTOM LINE: Hating exercise is a learned behavior. You are not born hating exercise. Yes, exercise can be challenging and intimidating--especially if you're new to exercise. Find an exercise, sport or physical activity you enjoy and you'll develop a positive association with exercise and all the benefits it provides.
