sigh....there is no such thing as "spot reduction".
you have to work your entire body. The best way to loose weight is
running. Try run for 5 miles 3 times a week, make sure to finish the
run within 45min for boy and 55 min for girl. run on a treadmill to reduce
impact on your knees. The most important thing is your shoes have to be right for you.
You will not loose weight in the first 2 weeks, but a lot in the next two weeks. If you have some extra money to spend, get a heart rate monitor asap.
