Your point of view is wrong! It is impossible to lose weight wherever you want, otherwise everyone is the devil. Of course, the waist is the easiest place to have fat.

I suggest you do aerobic exercise and sit-ups. Hula hoop is useless. Aerobic exercise for 45 minutes/day, sit-ups, lying flat, leg lifts at 90 degrees to the body (specifically, reducing stomach, ordinary sit-ups exercise the upper abdomen), 45 and 3 groups, once every other day. Stick to it for half a year, and you will find amazing changes!

Usually pay attention to walking more, and don't sit for half an hour after meals.
