You should take about 30-40 minutes for exercise, as bold and appropriate for you. Such as swimming , walking, running or other to do with the stomach to empty after while awake. Do not lie to yourself by eating before. Exercise in the morning that will burn fat is best. This means that you reduce weight quickly and not lose health course
If you want to reduce weight to the morning hours of the morning is the best diet. Instant results, and most every morning after wake up then.
