X3 officially launches today and you can find it here. Per usual, my role is what goes on under the hood, so let’s start at the roots the grew into this program: why we’d want to cut the P90X and X2 workouts in half. It all starts with science, which I’ve written about earlier. Check out these two articles, which cover the benefits of shorter exercise sessions.
In Cool Facts About Short Workouts you’ll find a ton of science.
Your body has an emergency response to exercise. When you begin, no matter what you’re doing, you burn glycogen for fuel. Once your body figures out that you aren’t in an emergency, it begins to conserve by shifting to body tissue, primarily fat stores, for energy. It was once assumed that training during this “fat burning” period was optimal for weight loss. Now we know it’s the opposite. If you take advantage of the glycogen window by training hard (and smart so you don’t get hurt) you can alter your body’s metabolism—the key to changing your body composition—quickly and efficiently.
In Why Short Intense Exercise Is Best, you get a critical view on an article that oversimplifies the benefits of short exercise. There’s more to subject than simply reducing the time you train. Maximizing those benefits takes strategy.
He also fails to mention the importance of not training the same way all the time or how longer more intense exercise can yield even more benefits. There is benefit of training all other systems, and even that walk around the block is not a waste of time. But I’m going to let him slide here because it’s not the article’s premise to discuss all aspects of training. His point is the easy aerobic cardio is not a very efficient way to change your body, which is true.
This stuff is merely the tip of the X3 iceberg, which uses the latest science as a jumping off point to creating a mega effective program requiring only 30 minutes of exercise a day. More to come….
