I want to lose weight in my legs?

Do leg toning excercises like squats, lunges, side lunges. If your not sure what these are google them; you'll find plenty of explanation. Do them for about 10-15 minutes a day - don't over do them. It will help build muscle in your legs. You can also jog, cycle etc. The key is to not pus yourself too hard, build up the amount of reps slowly each week.
