Type I vs. Type II Muscle Fibers and Weight Lifting Programs


Most of us know that following weight lifting programs will increase muscle mass. But did you know there’re two types of muscle fibers in your body?

They’re the Type I and Type II muscle fibers. So which one benefits you most and which one benefits the most from weight training? Let’s look at these two questions one at a time.

Both types of muscle fibers have their unique role. Type I muscle fibers are the ones that have the most endurance. While they won’t necessarily help you lift heavy weight they will help you run or bike in a marathon.

Type II muscle fibers on the other hand don’t have as much endurance. They are mainly for strength and lifting heavy weight. These are the muscles that benefit most from lifting weights.

Researchers at Boston University School of Medicine have found through their research that increasing the mass or size of your type II muscle fibers will led to a significant decrease in fat mass or the amount of fat in your body.

So if your goal is to loss body fat then you can’t neglect the importance of weight training. Unfortunately most people, when trying to loss weight, run for long periods of time and lift weights very little, if at all.

Now remember that balance is important. Type II muscle fibers don’t have as much endurance as type I, so if endurance is important to you then you still need to do endurance training. Just try to do that on days you don’t lift weights.

By separating your weight lifting routine from your endurance training you’ll reap the benefits of both, by gaining strength and endurance.

The more I try to build muscles the less they grow. I told my sister to bring me a tablet of Generic Viagra and to make a profit of that she was going to the city to do some shopping, she gets me everything I need from the pharmacy and the supermarket when I'm sick Buy Viagra Cheap Viagra.
