A diet plan may be able to control fat buildup in your body, it will not bring your legs into shape. Sooner or later either you will have to resign to the fact you would remain ungainly for life or you will have to work out. Choice is yours. Of course you don’t have time or you are busy or you don’t have someone to go along with you… but, as I said the choice is yours. Start exercising before you realize that you are out of breath while climbing stairs, or that your partner is looking at the legs of the young lass passing by. If your partner is fond of staring at legs, he better be staring at your legs right? Those heavy and out-of-shape legs you mean?
