Spot reduction is simply the idea that if you work a specific muscle group you will decrease the amount of fat in that area. The most common example of this is people focus on abdominal exercises in an effort to lose weight in their stomach area.
The truth is, how and where we lose fat depends on: genetics, hormones and age. If you want to lose fat around the thighs or belly, you have to create a calorie deficit (through exercise and diet), lose body fat and see how your body responds. What you’ll find is that, wherever you store excess fat is that last place you’ll lose it. For women, that’s often the hips, thighs and lower belly and for men it’s often the belly and waist.
Sit-ups, for example, will definitely strengthen your abdominal muscles, but sit-ups alone will not get rid of the layer of fat that is covering the muscles. To lose fat anywhere on your body you need to burn calories by following a program that involves both cardiovascular training and weight training. In doing so, you will decrease fat stores throughout your entire body, including the problem areas
