well as everyone knows you cant spot reduce!
but i will give you some hope
i have always had huuuuuge legs. big thighs and gigantic calves.
after losing 100lbs i finalllly saw some serious shrinking and toning and cellulite firming/reduction when i got below about 150 and majorly under 140. you really do just have to work on the body fat%.
i got an advance body fat% measurement and it showed my legs were many% higher...but the fat has nowhere to run, it will go down.
also, as you spend more time in maint at a steady weight body fat often redistributes.
