The first response is incorrect and ARCHIMEDES is right - you cannot spot reduce fat.
Doing ST does not make a body part less fat.
Doing arm work won't shrink arm fat. Doing crunches won't shrink belly fat.
That isn't how fat reduction works.
First - are we talking "fat"? Or is it loose skin?
If it's actually fat, then your genetics will determine where on your body you lose fat from. Keep up strength training, because it's good for you! Along with some cardio and a balanced, calorie-reduced diet. This is what kills fat on the body - but you don't get to target it from specific places you'd like to see shrink more.
