You could slot a certain time every day (preferably the same time every day) for exercise and this should be carried out without any interruption. In case you are not really a fan of exercising, try walking (which is an excellent cardio as well). Start with 15-20 minutes brisk walk and gradually extend it to one whole hour. Walking, cycling, swimming, are some of the exercises which are extremely beneficial not only to shape your thighs and legs, but also overall stamina and body tone.
Develop an outdoor sport hobby/ passion - choose from among the hundreds of outdoor games - be it tennis, squash, badminton, TT, golf, etc. where you could enjoy a brisk work out and have your exercise as well. The more active the outdoor game, the better your chances to fight the thunder thighs development. Such exercises help developing muscles and muscles always burn fat.
