Lower body muscle/pare shape - how to lean out lower body

I am in good shape, for myself. 20% body fat, 5’8, 143 pounds. Problem is I carry almost all of my weight in my lower body (thighs). My upper body is a lot smaller than my lower body.

My routine is 4 – 5 days a week of cardio, 1 hour of interval training on the elliptical, or1 hour of either steady state running (outside) or treadmill running at a fairly high speed for 20 minutes, the rest of the hour is a steady pace (6.1 - 6.3). I have been doing the increased speed for about 3 weeks. (incline 1.0 or 1.5) I do lunges, dead lifts, squats once a week high reps no weight (only body weight). (upper body do 2 days a week –arms one day, back another, abs their own day) I have been doing this routine for about 3 weeks and I find that the lower body is getting larger. Especially my legs. I build muscle easily (genetics). I wanted to slim down my lower body over the next weeks and am not sure what I should change in my workout. I do not want to gain fat by lowering cardio. I was going to cut out the leg training and try and do yoga 2X a week. Should I lower the pace of my running?  I only started doing the increased speed running (intervals) when researching how to shrink a pare shaped lower body.

Any advice?

my sister is in figure competitions and she had that problem. She really needed to slim down her legs, so she researched it, talked to other trainers (she is an ex trainer) and then got to work. She ended up writing an article for some website (can't remember which one) but here is the workout she switched to when trying to slim down her legs....the article is called "Trim the Fat"

"My new leg program consisted of combinations of the following, done as super-sets:

-       &n bsp;  Leg Extension, Leg Curl, Standing Calf Raise

-       &n bsp;  Back Extension, Donkey Kicks, Straight Leg Dead lift

-       &n bsp;  Stick Squats, Glute press, Seated Calf Raise

-       &n bsp;  Hip Abductor, Hip Adductor, Single-leg Calf Raise

I did 4 to 5 sets of 15-20 reps.  I kept the weight extremely low and kept my heart rate up the entire time.  In between each group of exercises, I did things like jumping jacks, jumping rope, or single laps around the track.  For the first month I was doing cardio once a day for 30-40 minutes.  Into the second and third month, I was doing cardio 2 times a day for 20-30 minutes for 5 of the days.  The other two days I was doing cardio 45 minutes to an hour, once a day.  3 days a week I would add variable sprints.  The sprints consisted of 75-100 meter sprints for about 10-15 minutes.  I would sprint/walk/sprint/walk.  I was able to observe my legs lean up and slim down.  It is also important to note that I was eating an extremely high protein, low fat, low carb diet.

       &nb sp;    Most women know that the legs are the last area on our bodies that slims down.  I had to remember this and remind myself of this the entire 2 ½ months.  Why did I have to remind myself this?  I had to be careful not to over train or lean down too much in the rest of my body.  I continuously had to tell myself that my legs would truly lean out about 1 ½ to 2 weeks prior to contest.  Luckily, that is what indeed happened."
