It is impossible to say whether you are overweight just from your height. You might have anything from a very heavy build to a very light one.
So, try an experiment .. (For the sake of modesty, let's assume that you have a pair of boxer shorts on
) ... Jump up in the air while looking at yourself in a full-length mirror and tense all your muscles. When you land, can you see anything wobble?
If the answer is 'no', then you probably don't need to lose much weight, unless you are one of those people..
