This is the WW ranges for 5'2
First it depends on how old you are
the maxiumn for ages up to 25 years of age is 125.
25-45 y.o is 131
45+ is 136
I am 5'2 & I want to be where you are at. Actually, I did feel comfortable @ 130. The lowest I ever got to was 118 & that was in high school & I was way too skinny. The minimum range for 5'2 according to WW is 109. I tried to be that weight when I was a teenager & never suceeded.
You will probably make those thighs look sleeker with cardio & weight lifting. Remember we have short legs & we will never look like the people who have long legs. I know how you feel, because I hate my chunky legs too.
