The key to losing inches off of your waistline, is by burning fat. Not just spot training or “spot reduction exercises.” But you can incorporate strength training, weightlifting, cardio and specific exercises to help with the fat reduction. I have found that doing toning work along with cardio and fat burning work, has helped with reducing overall body fat and also with creating more muscles in the areas being worked, providine what appears to be spot reducing affects. And along with that, you can work specifically to tone muscles in your abdominal wall, and the larger muscle groups in your legs, and that will assist with slimming the body overall, even if you aren’t burning fat specifically in your abdominal area. Diet and exercise combine to help with burning fat and losing inches. Below are some more resources.
