The key to getting your flat stomach back after having a baby is to follow a systematic and progressive workout plan as well as watching your diet. When beginning a workout program after having a baby one must remember that their body has just gone through some huge changes and will take some time to get your body back to the way it was.
The first step is cardio. Walking, running, jump roping, tennis, etc. These types of activities will help you get your heart rate up and help you burn calories, helping you melt away any fat. Follow your cardio workout with some abdominal training and resistance training. When beginning your workout program start by stabilizing your muscles. Stabilization simply means using your inner core and back muscles to hold you stable while performing an exercise. So an example of an abdominal stabilization exercise would be a plank hold.
Another trick to getting your flat stomach back is to workout your core out in as many ways as possible. Regular crunches alone are not going to do it. You have to work your upper abdomen, side obliques, lower abdomen, lower back, butt and inner stabilzation muscles. Working your core out in all directions will not only give you a flat stomach, but it will also give your lower back support which can help diminish back pain.
Now the ultimate key to getting your flat stomach back is to draw that bellybutton into the spine. It takes a conscious effort on your part to keep those stomach muscles tight while working them out. It may hurt more, but this is the key to getting your stomach tight and toned. Be mindful of the muscles you are working on.
And the last thing is to watch what you eat. You will not see the results your are looking by eating whatever you want whenever you want. You have to eat healthy and be conscious of what you are eating and how much. A healthy diet of 6 small meals a day with lots of fruits and vegetables will help you see the results you are working hard for!
