It’s very common for some one to lose 30 pounds and then for some reason go looking for the magic exercise that is going to get rid of the final lower belly sag. In most cases it is not an exercise that is need but more fat loss.
The body loses weight from the extremities in. So the last place to get really lean when you are losing weight is usually the hips, thighs and lower belly. Doing another exercise for that area is not going to hurt you but it probably is not the ticket you are looking for if you want to get really lean in that area.
The shortest route to getting rid of that extra tissue around lower belly is whatever it is that is going to cause you to burn off more fat. Depending on how you want to go about that it could be a more strict diet, more cardio or a higher level of intensity on your resistance training.
Another cause of the lower belly sticking out is bad posture. Sometimes the hip flexors get really tight and pull on the lower back area. This causes a sort of sway back look like you see on a tired old horse. The lower back gets pulled in. The glutes stick out and so does the belly.
Sometimes a good stretching routine that lengthens out the hip flexors and gets them to relax will flatten out the lower belly area. The glutes and lower back will level out a little and the front of the body will even out to the point where it is flat even when you don’t try to hold it in.
You can shorten the hip flexors by doing to much sitting and improper abdominal movements. Things like the sitting bikes for cardio always keep you in a shorten position. This over time can cause the hip flexors to shorten up by getting tight. You can see it become really apparent when people have a short walking or jogging stride. They will not achieve full extension on their stride.
When you do exercises like the hanging leg raise without lifting your hips, you can also tighten up the hip flexors. This will happen when people only lift their legs. You’ll know you are lifting with only the legs if you feel the burn in the crease where your upper thigh and front hip bones meet. Where you should be feeling it is in the front of your torso. A gradual fading burn from the lower area to the upper area of the abdominals. In order to accomplish that feeling you must lift your hips forward. Roll the front of your hips up towards your chin instead of only lifting the legs. It’s a small difference but will make all the difference to where the movement effects your body.
I hope that helps you out and remember that the shortest route to getting rid of lower belly fat is not a single magical exercise but a combination of stricter dieting, proper form and resistance training.
