What are good workouts to get rid of lots of stomach fat?

Any exercise which reduces body fat will reduce stomach fat. There are no exercises which specifically target fat in a certain body region. If you want to lose your gut, you'll have to reduce your total body fat. Any moderately-intense cardiovascular exercise, such as running, biking, swimming or hiking (and many more) is a great way to burn calories. The American Heart Association recommends at least 60-90 minutes of exercise most days of the week for those trying to lose weight or maintain weight loss.
