I am a malayali girl studing in class11th... my problem is that my but size it 40 so when I walk or?

the thing to do is tone it up a bit if you can use gym at school its a good idea to see if you can use a machine called the bycicle thats what it looks like to me you could use a stair stepper or one of those machines that you walk while its moving the next thing is to use one of the those roller machine where you use your feet to push up and going back and fourth watch your carbs and calorie intake cut the sugar out of your diet which to can help you tone there is a old fashion machine that you put the belt around your bottom and it will shake thats a excellent machine to use for toneing you can also use a regular fittness club if possible
