If you are looking to lose weight quickly or tone up then Insanity cardio workout is for you.  Insanity is an awesome cardio workout. Insanity has been the best in-home exercise program that I have ever had. I started seeing results in less than 3 weeks. You lose weight fast but the results included better physical condition not just weight loss. I play sports and my endurance increased significantly. I would recommend this workout to anyone that wants to get in shape. It is not for those people that don't want to work. You will be working your butt off.
