Since everyone is so hell-bent on having a thick upper body, the other half of their muscles down below often get ignored. They will come up with just about any excuse to avoid hard and heavy leg training, saying things like "I just run to develop my legs", "squats are hard on my knees", or some other similar bogus reason.

I cannot even begin to stress how costly a mistake this really is...

Not only does it look ridiculous having a ripped and muscular upper body sitting atop a pair of toothpicks-for-legs... but this inane refusal to place equal muscle building focus on your lower body limits the massive muscle growth that you can achieve on your chest, back, arms, and shoulders.

See, most people think of weight training as a simple black and white issue of "train muscle X using exercise Y, and muscle X will become bigger and stronger". Having such an incorrect view on massive muscle growth will is the biggest reason why most people don't get the results that they want.

Here's a fact.

The muscle building mechanism within the body goes far beyond a simple localized event that happens at the level of the muscle tissue itself! A great deal of massive muscle growth also results as the entire body as a whole is placed under stress and adapts on a holistic level.

This is achieved through the increased secretion of important hormones such as testosterone and growth hormone. If a bodybuilder injects anabolic steroids into his body, he's attempting to up the circulation of these important substances in order to attain massive muscle growth.

Now, because you're a natural trainee and jamming a roid-filled needle into your butt just isn't your style, you've got to find other methods of speeding up the production of these muscle-increasing compounds in order to gain massive muscle growth.

And what is one of the most effective ways to do this?

Hitting the leg muscles hard and heavy! Leg presses, squats, stiff-legged deadlifts, lunges. Did you ever notice how incredibly challenging and downright gut wrenching these exercises can be when performed to a high level of intensity?

The best thing for massive muscle growth!

After finishing an all out set of these lifts you may find yourself wishing that you hadn't come to the gym in the first place. That's because they hit the largest muscle groups on your body and enable you to move massive amounts of weight.

But look, although these leg exercises need mental toughness and willpower, their intense difficulty forces your body to rev up its anabolic hormone production. When you build up your anabolic hormone levels, it will result in greater muscle size and strength for both your lower and upper body.

What this means is that if leg training is not a regular part of your workout schedule (or if it is part of your schedule but is simply treated as an after-thought), you are missing out on significant total body gains, like massive muscle growth, that you could otherwise be achieving.

I'm not kidding you.

To your weekly workout schedule, add a day of intense leg training. Work with basic compound lifts like squats, leg presses, and stiff-legged deadlifts, and focus on pushing yourself and adding more weight to the bar every week.

After 4-8 weeks, come back and tell me if you've noticed massive muscle growth. If you're like 99% of the population, you'll report that your strength on every single upper body exercise shot through the roof... and that your chest, back, arms, and shoulders became noticeably thicker and more muscular as a result.

I'm not going to force you to, if you don't care about the size of your legs or massive muscle growth. At the very least, include hard and intense leg training for the sake of those upper body muscles that you covet.

It may not seem logical at first...

But the fact is that consistent, intense leg training is the key to massive muscle growth for a ripped upper body!
