I am sure that you have seen numbers articles titled Best Jeans for Your Body Shape/Type. I feel that this type of article is a "must have" every 6 months to a year in all Fashion, Fitness, and Women's magazines. BUT, have you heard that there are different workouts for your specific body type?
I came across this article on the Women's Health Magazine site. This was also not the first time that I have seen something like this before. I am a magazine junkie and at one time I subscribed to about 7 magazines and at least 2 of them were fitness oriented. Anyhow, basically it is saying that you may have more success if you have a workout tailored to your body shape. They also cover common tips and pitfalls of that body shape. For instance, hourglass shaped ladies, like myself, tend to gain weight all over and they usually lack all over muscle tone. Personally, I feel that this fits me perfectly. When looking at pictures of myself as I gained some weight, Amber likes to say that I just "spread", as horrible as that sounds. My weight gain was distributed pretty evenly.
On the other hand, I almost feel that working out for just your body type is very similar to spot training which is a myth in exercising. (Spot training is just focusing on one part of the body. IE.. if you want hot abs, you do sit ups all day instead of incorporating some cardio and all over toning workouts.) In my opinion, I figure that if the body shape workout covers all aspects of your body using cardio and strength training, than it may actually work. I haven't tried one yet, but I am tempted. Maybe after I finish the 30DS.
