I started to practice a new Insanity routine and I was looking for the perfect way to compliment my training with some butt exercises when I found this excellent guide. This is full of useful and effective tips and exercises to sculpt and tone up this area of your body. The best aspect of this guide is that most of the routines given there can be realized at home and, after a few weeks practicing, I can assure you that you will feel the effects of your effort since day one.
