Heh - i'm another one with the same problem lol.
I do a lot of heavy lower body weights and a lot of squats/lunges. I also find running and spin classes to be effective at toning.
I also do upper body strength work because I have found having toned shoulders, arms and back balances the width of my hips and gives a more overall athletic appearance.
I'll always have these proportions but hey...now I have defined calves, sleek, muscular thighs and a perky backside - definitely sexy
And anyway, supposedly the most "attractive" waist to hip ratio is 0.67 - and mine is 0.65 - so I am definitely not complaining!
Except of course when I try to buy jeans lol - I am, however, convinced jeans were not designed to fit ANY shape!
