If the size of your hips is due to fat, however, aerobics and training can absolutely assist in reducing inches and toning. Pilates is a form of exercise that appears to be particularly suited to targeting specific areas of the body. If this is the case, you might consult a trainer or explore some pilates sites and/or DVDs to see what might work best for you.
A good way to assess body fat is BMI (body mass index). Check with your physician or health club for an inexpensive BMI measurement to help determine muscle/fat ratios.
