Butt, Thighs, Legs

Oh my gosh, i looked in the mirror today from the back side and about died. Thats not my body, thats not me, holy buns and thighs! I have always had big legs and thighs but now... wow! I need to work on them seriously because all this weight is going straight there. I see my self in a bikini and i walk around in sports bras, no problems but im always only looking at the front which is the belly.... from the back? A whole nother story. I am going to add squats and leg lifts to my work out. It will probably be the next challenge for me but i will begin tomorrow.
