Ok, Let’s bust this! Doing crunches will help you get rid of belly fat… This is false to an extent. Getting a flat stomach starts in the kitchen. You have to eat properly to lower your all around body fat so that you start to show muscle definition. However, you have to do crunches and ab exercises in order to develop muscle tone and have something to actually show. Cardio is really good for lowering all around body fat so make sure you’re incorporating that too at least 3-5x/week for 30 minutes to see maximum results.
