A lot of bodybuilders tell me they have an intense desire to slap on as much muscle as they can, but sometimes I have to wonder if they really mean it.

After all, they don't want to do the little things that can have a big impact on muscle gains. They say, "I don't have time" or "That's too much work."

It all comes down to how bad you really want to put on muscle.

So you don't make the same mistake as some of these other bodybuilders, I'm going to share a mistake I see a lot of them making when trying to put on muscle mass. It's this:

They are not paying enough attention to their post workout meal!

I know you've heard the importance of taking a post-workout meal before, but not the way I'm talking about. Most "experts" say, "as long as you take a meal containing carbohydrates and protein within 90 minutes after your workout you'll be using this "window of opportunity" for muscle growth."

I say, "Why in the hell would you wait so long for the most critical time of your recovery, for muscle growth." Cortisol is rapidly rising right after the workout and if you don't do something to put a stop to it, it's going to eat away at your muscle gains.

To stop cortisol from rising you should take your post workout shake immediately after your workout. Premix if you can and bring it to the gym with you.

The bare minimum in your post workout shake should be high glycemic carbohydrates and protein.

Why high glycemic?

Actually there are two reasons: the first is, scientists have figured out insulin and cortisol are antagonistic, meaning when your insulin levels are high cortisol is driven out of your body. This tilts your testosterone to cortisol ratio in favor of testosterone.

The second is glycogen depletion after a workout. If you've properly done a hard enough workout, your muscles will be depleted of carbohydrates, because you used them up during your workout. Your muscles are literally screaming for some more carbohydrates right after the workout. They will quickly absorb the carbohydrates, so it is important to get them into your body as soon as possible.

While your body is in this quick uptake mode, you can use the carbohydrates to shuttle other "anabolic" nutrients into your body. The applications are unlimited!

But, first you have to become a post workout fanatic and take it in as soon as you can.
