I suggest you go find a pneaorsl trainer or someone whos been trained and who knows what he is doing. He'll be able to know what you want and give you the right plans to follow. He'll also be able to know what you are doing wrong and help you do it properly. If money is an issue then just get one for 2-3 lessons.Usually it takes about a few weeks, couple of months to see a good result.References : Ex bf's mother is a pneaorsl trainer .
