Weight Training: The Best Way to Get Lean

By Steve Edwards

Weight LifterWhen it comes to reshaping your body, nothing is quite as effective as lifting weights. Cardio is great for your heart, Pilates will help you get stronger, and yoga will balance you out; but nothing compares with a well-designed resistance program for getting lean.

This is in contrast to our weight lifting cultural icons. Arnold, Hulk Hogan, and the WWE are who and what we tend to associate with pumping iron. It may be more accurate, however, to associate those massive bodies with anabolic steroids and turn our attention to the real cultural icon for weight training: Jack LaLanne. The guy who practically invented "lifting" as we now know it is well into his 90s and can still ace the fitness standard designed for a 30-year-old. Once considered a bodybuilder, his legacy has far more to do with his fitness exploits than his brawn. His feats include things like swimming with his hands and feet shackled and towing 70 people in 70 boats across Long Beach Harbor on his 70th birthday. The key to Jack's success over all these years has been lifting weights.

P90X®In his intro to P90X's Chest, Shoulders & Triceps workout, Tony Horton tells us, "It's just good old-fashioned weight training that's gotten lost in a lot of fancy gidgits and gadgets and things that don't work." But weight lifting is making a comeback. In a couple of months, Turbo Jam® creator Chalene Johnson will unveil her new program focusing on weight training as the path to a lean and healthy body. As scientists look for the latest way to halt a growing obesity epidemic, the research still leads them back to the same simple fact: resistance stimulates the muscles to work, which causes an effect throughout the body that keeps it strong, healthy, and lean. Let's take a brief look at why.

The basics of body composition

The science of how our bodies work is complex. However, the basics of body composition, and why we get obese and out of shape, are very simple. Due to the former, we can see how it's possible to believe that one magic nutrient, drug, or movement might transform us from fat to fit. But once we understand the latter, we see how this is highly unlikely, if not impossible.

Body CompositionA simple overview of body composition looks like this. At the base is a skeleton that is held together with connective tissues. This encases most of your organs and circulatory system. Muscles surround the structure and enable it to move. Body fat protects the organs and joints. It's all covered by your largest organ, your skin. We're leaving out some obvious functionality but this is basically what makes up your body composition, which determines your shape.

While there are different body types, all of them look good when all of the above are in the correct proportion. We look worse when our body fat percentages exceed their intended uses. Excess body fat inhibits the body's natural ability to function, and, hence, leads to myriad health problems. To correct this, we need to reduce the amount of body fat in our bodies. There are many ways to make this happen. Eating less, eating better, and exercising moves the process in the right direction. But the easiest way to do this is to add muscle. And the best way to add muscle is to exercise using resistance.

Weight training basics

Planning a WorkoutMost weight training is what we call anaerobic. This means, simply, that the intensity it takes to do it exceeds your body's aerobic (oxygen-carrying) capability. Anaerobic training relies on something called the Krebs cycle, which is a process in each cell that puts the body under stress. This stress forces your body to adapt and works nearly every human function we associate with fitness, including your body's aerobic system. So, oddly enough, a well-crafted anaerobic workout program is all the work you need to have a perfectly healthy aerobic system. This is because recovering from anaerobic work requires your aerobic system to work. If you can understand this concept, it will be easy to understand why weight training is so vital.

The fat-burning misnomer

Many less intense programs, like aerobics and most "cardio" programs, focus on training in what some people call the "fat burning zone." This term is misleading because what it really means is utilizing fat for fuel—not burning body fat. Well—wait—it does actually mean that. The process is a little complicated, but I'll simplify it.

Guy with DumbbellAt low-level outputs, your body burns its stored fat as fuel. At higher outputs, it burns sugars that have been stored in your blood and liver, called blood glycogen. It's important to do both, but targeting fat mobilization as your primary fuel source in your workout makes little sense, unless you're training for endurance sports.

Your body has a limited store of glycogen—about enough for an hour or so of hard work. It attempts to save this for intense exercise (and brain function) and tries to do low-level tasks by burning body fat. Training at low intensity has a benefit, but it's only a fraction of what high intensity can accomplish in the same amount of time. And even though you are burning stored fat instead of glycogen, you aren't stimulating your muscles in the same way. This lack of stimulation means that you aren't creating the same level of hormone release, organ function, or muscle growth. The result is that you get far less fitness improvement in a given amount of time.

The metabolic process

Muscle Burns FatThis is, at its most basic, the speed at which your body engine runs while resting. The more fit you are, the higher your metabolic rate is likely to be. Excess muscle on your body takes more energy just to keep it there. Body fat doesn't have the same requirements. In fact, it sort of does the opposite, by gumming up the works and inhibiting the metabolic process. Remember that muscle is there so that the body can move and do stuff. Fat is there to protect the body, especially the organs. It is similar to having a spare tire sitting inside of you. It adds weight and slows you down but does nothing helpful for your metabolism. This means that the most effective way to burn body fat is to add muscle to your frame because it burns fat around the clock. That is precisely what Chalene Johnson's new program will do—and you'll be hearing a lot more about "muscle burns fat" in the coming weeks.

Why your scale is lying to you

Using the above body-composition basics, it's pretty easy to understand why losing weight should not be your ultimate goal. Instead, you should focus on losing body fat, which means that you'll get smaller at the same weight. By volume, muscle weighs far more than body fat. So much so that by adding muscle you can actually gain weight as you shrink. This isn't true for most people, but many "skinny fat" people find that all of their health indicators improve as they gain weight.

Overweight Man Working OutThis is especially important to consider if you're highly de-conditioned, because not only do you have more fat on your body than you should, you probably have less muscle. As this ratio comes into balance, the scale may not be dropping, but your body can be making substantial changes. Furthermore, weight training can change your bone density. This does not increase the size of your bones but increases their weight and strength. For this fact alone, it's recommended that everyone add some resistance training into their lifestyle as they age.

What to do if you want lean muscles instead of bulky muscles

The bad news is that there is no such thing as a lean muscle. The good news is that there is really no such thing as a bulky muscle. We use these terms to describe a body type, not a muscle. Lean muscle is also a term that means, well, muscle. All muscle is lean. Body fat is not lean. So the only non-lean muscle is one that has excess fat around it.

You can't really change a muscle's shape. It either grows, called hypertrophy, or shrinks, called atrophy. Weight training programs target muscle growth. All muscles are lean and shapely. To look lean and shapely, you want to build your muscles so that your metabolism increases and your body-fat percentage decreases.

Woman Bodybuilder"Bulky" (in quotes, because it's a matter of opinion) is a term used for muscles that are larger than normal. These are much harder to get than most of us, especially women, tend to believe. Bodybuilders certainly wish it were a lot easier. But adding excessive muscle takes an almost obsessive amount of work. Due to gravity, our bodies don't like to weigh too much and resist adding muscle. It's easier to add excess fat because not much can be done about overeating. Adding bulk is so difficult that steroids have become a huge societal problem.

It's also easy to control whether or not you become "bulky" through the number of repetitions (or time spent) doing resistance work. Sets that are longer than 12 or so repetitions (or about 30 seconds) self-limit the muscle's ability to grow. Therefore, those looking for a "lean" look should target higher reps once they've decided that their muscles are large enough.

And the added benefit of antiaging

Weights and a Man Weight Lifting

Finally, nothing helps you age more gracefully than weight training. There are other ways to stay lean, but using resistance training creates hormonal releases that offset the aging process better than anything else. Furthermore, you lose muscle as you age—about 1 percent or so per year beyond the age of 30. Antiaging medicine is often prescribed in the form of injections of the very same hormones that are released when you do intense resistance workouts. Weight training is a cheaper, and arguably more effective, alternative to spending a lot of money on doctors. Just ask Jack LaLanne.

Can a Chuckle a Day Keep the Doctor Away?

By Tony Horton, creator of P90X®

So a duck walks into a bar . . . Did you know that there is actually a scientific name for the study of laughter? It's gelotology. Laughter is such an important part of our everyday lives that it can actually make us healthier. Smiling and laughing release all kinds of good chemicals and hormones in our bodies—the physiological and psychological effects are well-documented. And let's face it, laughing at a good joke or situation, funny or not, just plain old makes us feel better. But how does laughter work? And how can we use it to make our lives healthier and happier?

A Girl with a Seal

We actually get exercise when we laugh or smile. Yes, it takes fewer muscles to laugh or smile than it does to frown, but it's much more fun. So for once, I'm telling you to exercise less, smile or laugh more, and you'll be healthier. Laughter is such an important part of my life that I make an effort to surround myself with friends who make me laugh.

Laughing with FriendsResearch shows that laughter actually protects the heart. Researchers don't know exactly why, but studies show that when we're stressed, the endothelium—the protective layer in our blood vessels—decreases, thus allowing cholesterol to build up in our arteries. Heartfelt laughter can lower the serum cortisol released during a stress response and can, therefore, lower the risk of hardening of the arteries. It has also been linked to lower blood sugar levels in people with diabetes; it increases antibodies and killer cells in our bloodstreams, thus helping us fight off disease; and it increases blood flow. And get this: Laughing 100 times equals the same aerobic output as 10 minutes on a rowing machine or treadmill.

So how do we use laughter in our daily lives? How do we turn the tide of negativity and stress that so often makes up the bulk of our days? We simply make a choice. Decide in your head that you are going to seek out the positive, the humor in any given situation. Granted, not all situations warrant laughter or smiling. I don't want anyone to get punched. But the next time you see another person, anywhere, smile at him or her. Not only will you feel better, they will too; and it's fun to watch people's reactions. Flood your mind with thoughts that make you smile, a good joke, a friend you haven't seen in a while, a great trip you once took, a goal you reached or are going to conquer—anything positive that will bring a smile to your face or make you laugh. That's half the battle; the body naturally takes over from there. When confronted with a stressful situation, smiling actually reverses the chemical response in your body. And chances are that if you smile, the situation will be diffused before you can even think about stressing out.

Tony Horton's 10-Minute Trainer®In every aspect of your daily life and interaction with others, a smile goes a long way in getting people to do things you may need or want. The next time you get ready to work out with 10-Minute Trainer® or P90X®, put a smile on your face and think how great it will be, not what a burden. We do make a conscious choice over what emotions we choose to allow to flood our bodies. Laughter and smiling are natural physical responses to those emotions. And now that you know it, laughter and smiling can actually make you feel better and live a longer, healthier life. Well, there's no other choice. Laughter really is the best medicine.

Test Your Weight Lifting IQ!

By Joe Wilkes
  1. Lean BodyFALSE: Weight training will bulk up your muscles. Weight training can bulk up your muscles. It can also give you long, lean muscles. Many people, especially women, avoid weight lifting because they don't want to achieve that bulky 70s-era Arnold Schwarzenegger look. But depending on the amount of weight you use and reps you do, weight lifting or resistance training can give you the kind of muscles we associate with lean, toned bodies.

  2. TRUE: Weight training can positively affect blood pressure, osteoporosis, and insulin resistance. Weight lifting has been shown to be effective in lowering blood pressure, increasing bone strength, and regulating insulin and blood sugar levels. A balanced regimen of aerobic and anaerobic exercise has been proven to be as effective as many medications in treating all of these conditions.

  3. Weight Lifting SpotterFALSE: Machines are safer and more effective than free weights. There is no evidence that machines are any safer than free weights. With most weight lifting exercises, either using machines or free weights, trainers recommend that there be a spotter present. As for effectiveness, many studies have shown that free weights can be more effective, as you have to engage more ancillary muscles in addition to the muscles you're targeting to guide the weights.

  4. FALSE: You'll get better results if you lift every day. Your muscles actually grow and become stronger when you're resting, so most trainers recommend taking two days off after lifting. For the sake of time management or routine, many lifters will alternate muscle groups during workouts so they don't target the same ones every day, thereby still working in some weight lifting into their daily routines.

  5. AmmoniaFALSE: Smelling ammonia on your clothes is a sign of a good workout. If you smell ammonia on your clothes after a workout, that's a sign that you're metabolizing protein instead of carbs and fat, i.e., you're burning muscle, not fat. If this happens to you, make sure you eat a balanced supply of carbs before you work out. A good way of ensuring this is to have a balanced product like Beachbody's Meal Replacement Shake or P90X® Peak Performance Protein Bars before a workout.

"OH MY GOSH. I'm so glad this article came out. The last question on the quiz has floored me. I kept wondering why I seemed to be sweating ammonia during my workouts. I had never come across anything that explained it, as well the way it seemed like I couldn't really gain much muscle even though I was working out pretty hard. I had NO IDEA. So good to know that all I need to fix it is a pre-workout meal, which I never did before. Thanks so much for solving that mystery for me."

– Mallorie, Toddville, MD
