Are you guilty of training only the parts of your body that you want to improve? I know it is tempting to only train those parts that you are unhappy with, but in the long run, that's not what is best for your body.
So here is what you do: Train your body as evenly as possible. Many women (and men) will pick a body part they don't like (inner thighs, abs, butt, etc) and work more on that than on the rest of the body. Some men typically only train their upper bodies and forget about their lower bodies all together. This is bad because it can cause muscle imbalances that will lead to overuse injury, poor posture and an unintended physique. It is important to train all parts of your body along with the areas you are looking to improve. So, if you work your right side, work the left too. If you work the your front, do something to work your back too.I know it may seem counter-intuitive to train your quads (front of your legs) and your hamstrings (back of your legs), but trust me when I say that you'll be much more pleased with the end result if you take this approach.
