Benefits of High Intensity Workouts

In relation to getting into shape, the terms high intensity and low intensity are used a lot but aren’t defined with nearly the same frequency. I suppose that’s because we’re all supposed to know the difference…but many don’t really understand the difference at all.

In general, low intensity exercises work your heart rate at around 60 percent of your maximum heart rate. A high intensity exercise works your heart rate at around 75 percent or more of your maximum heart rate. I suppose this means that anything working your heart at between 60 percent and 75 percent of your maximum heart rate is a moderate intensity exercise, but they must have a bad public relations firm because you don’t hear much about them.

You can determine your maximum heart rate by taking your current age from 220. So, for example, if you’re 50 at the moment, then your maximum heart rate is 170 beats per minute. Don’t let the term “maximum heart rate” fool or scare you. It isn’t referred to as such because it’s the maximum rate your heart can beat before damage occurs; it’s simply the absolute maximum rate your heart will beat.

The 220-age formula is only an estimate and, depending on your individual physiology, you may find yourself exceeding that number. That’s fine, you shouldn’t panic because it’s nearly impossible to damage a healthy heart with exercise. High intensity exercises are simply much more beneficial for your overall health. Aside from burning calories, these exercises help increase muscle mass; low intensity exercises don’t do this. Even if you’re not looking to become a bodybuilder, building muscle is always a good idea for your overall health and prevention of accidental injuries during everyday life.

Low intensity exercises also don’t do very much to increase your overall metabolism while high intensity exercises do. This increase in metabolism is crucial to overall weight loss and general health.
With the exception of the injured, ill, out-of-shape or elderly, there is no reason for anyone to stick solely to a low intensity workout. If you do happen to be in poor shape, then you should begin exercising with a low intensity workout for a little while as you build up to high intensity exercises.

So why do people stick to low intensity workouts? The main reasons are because low intensity exercises are easier and a trainer may have recommended it. Wait…If high intensity is better, why would a trainer recommend low intensity? The two main reasons are personal liability and a misunderstanding of the numbers involved. Basically, you are much less likely to injure yourself during a low intensity workout, so a trainer is protecting themselves by recommending a safe exercise plan. This is easy enough to understand, although a proper trainer will do their job and train you not to injure yourself during high intensity exercises.

The second reason, a misunderstanding, requires a bit more explanation. You see, low intensity exercises burn a higher percentage of calories from fat than high intensity exercises. Low intensity exercises burn approximately 50 percent fat for energy while high intensity exercises burn approximately 40 percent fat for energy. This difference is not great enough to justify the tradeoffs. Besides, it doesn’t actually mean you burn more fat with low intensity exercises. Confused? This is where the misunderstanding comes in. Hypothetically speaking, let’s say that you burn 100 calories by walking for 20 minutes. Walking is a low impact exercise, so you burned 50 fat calories (50 percent of one hundred).

Ten minutes of high intensity exercise, however, can easily burn 160 calories. Since high intensity exercises burn 40 percent fat for energy, you just burned 64 fat calories. You burned 14 more fat calories, but only spent 10 minutes doing it. Basically, the percentage is technically smaller, but you burn more total calories in less time with high intensity exercises. A smaller percentage of a bigger number is better than a bigger percentage of a smaller number.

In addition to this, low intensity workouts only burn fat calories while you’re actually doing them. High intensity workouts, because they increase your metabolism, continue burning fat for hours after you’re done working out. And, because muscle burns more calories than fat, the increased muscle mass means you’ll be burning more calories every second of the day because of your high intensity workout. As you can see, there really isn’t any reason to stick with a low intensity workout when you can step up to a high intensity workout and get a greater benefit in less time.

WHAT IS POSE METHOD®?

This weekend I am going on a road trip to CrossFit Colosseum in Toronto. Rick and I will be attending the CrossFit Running Certification. We will be taught the POSE METHOD.

The Pose Method® is a system for teaching of human movement developed by a 2-time Olympic Coach Dr. Nicholas S. Romanov in 1977 in the former Soviet Union. The name of the method comes from the word "pose" or "body position".

If you analyze the movement of any body through time and space, you will clearly see that the body passes through an infinite number of positions. Most of the positions (or poses) are transitional movements and are the result, not the cause, of proper positioning.

Eicosanoids - Powerful super hormones

The essential fatty acids omega-3 and omega-6 are transformed in the body into hormones called eicosanoids, e.g. prostaglandin is an eicosanoid. They all have 20 carbon atoms, and the name comes from the Greek word eikos which means 20. The Nobel Prize for Medicin was in 1982 given to Sune Bergström, Bengt Samuelsson and John Vane for their research about eicosanoids. The first eicosanoid (prostaglandin) was discovered in 1936 by Ulf von Euler.

Dr. Barry Sears calls the eicosanoids powerful super hormones. They control other hormones and practically all important functions in the body, e.g. the central nervous system and the immune system. Thus, they are very important for good health and well-being. There are both good and bad eicosanoids, and a good balance between them is achieved by eating food that contains both omega-3 and omega-6.

There are also other things that determine the balance between good and bad eicosanoids, such as the hormones insulin and glucagon. A diet consisting of a high amount of carbohydrates - especially fast carbohydrates - creates too much insulin in the body. This means that there will be an over-production of bad eicosanoids. A zone-favorable diet means less carbohydrates, this will produce more glucagon and good eicosanoids which enhances health. The fatty acid EPA is an important fat since more good eicosanoids will be produced. A high consumption of the short-chain fatty acid ALA can interfere with the production of eicosanoids, according to researcher Barry Sears, and the same is true for trans fatty acids.

Barry Sears explains in his book "The Zone" why both good and bad eicosanoids are needed in the body. The good ones prevent the blood from clumping, which lowers the risk for blood clots. However, when you bleed, the bad eicosanoids are needed in order for the blood platelets to aggregate and stop the bleeding. This is why the balance between them is important, since they are both needed in the body.

There are inbalances that lead to disease, inbalance between insulin and glucagon, good and bad eicosanoids, omega-3 and omega-6, and carbohydrates, proteins and fat. If you eat healthy the levels are adjusted automatically. Read more about eicosanoids and why fast carbs are bad for your health in the book "The Zone" by Barry Sears.

Health Benefits of Walnuts

Walnuts are one of the best plant sources of protein. They are rich in fiber, B vitamins, magnesium, and antioxidants such as Vitamin E. Nuts in general are also high in plant sterols and fat - but mostly monounsaturated and polyunsaturated fats (omega 3 fatty acids - the good fats) that have been shown to lower LDL cholesterol. Walnuts, in particular, have significantly higher amounts of omega 3 fatty acids as compared to other nuts.


More than a decade of scientific evidence shows that incorporating walnuts in a healthy diet reduces the risk of heart disease by improving blood vessel elasticity and plaque accumulation. Walnuts have also been shown to aid in the lowering LDL cholesterol (the bad cholesterol) and the C-Reactive Protein (CRP). CRP was recently recognized as an independent marker and predictor of heart disease.

FDA Approved Health Claim for Walnuts

In 2003, the FDA recognized the benefits of nuts and their role in heart disease prevention by approving a health claim for 7 kinds of nuts (almonds, hazelnuts, peanuts, pecans, some pine nuts, pistachios and walnuts). These seven nuts were approved as they are the only kinds that contain less than 4g of saturated fats per 50g.

In response to a petition filed by the California Walnut Commission, the FDA further endorsed the health benefits of walnuts by approving the following health claim in March 2004.

"Supportive but not conclusive research shows that eating 1.5 oz of walnuts per day, as part of a low saturated fat and low cholesterol diet, and not resulting in increased caloric intake may reduce the risk of coronary heart disease."

Walnuts in a Healthy Diet

Nuts in general are high in calories, so moderation is the key. The best approach is to reap the health benefits of eating walnuts but not add excessive calories to your daily intake. Therefore, instead of just adding walnuts to your current diet, eat them in replacement of foods that are high in saturated fats (such as cheese and meat) and limit your intake of these tasty treats to the recommended 1.5 oz per day. That is about 20 walnut halves.

Walnuts add a flavorful crunch to dishes. Here are some simple ideas to incorporate walnuts in your diet:

instead of snacking on cookies, crack some walnuts open and eat them as snacks
instead of using meat, toss toasted walnuts in your salad or pasta to add some crunch
instead of layering pepperoni, use chopped walnuts in your pizza
instead of eating bacons or eggs, use walnuts as a protein choice by sprinkling chopped walnuts in your oatmeal or breakfast cereal

Theoretical Heirarchy of Development

A theoretical hierarchy exists for the development of an athlete. It starts with nutrition and moves to metabolic conditioning, gymnastics,weightlifting, and finally sport. This hierarchy largely reflects foundational dependence, skill, and to some degree, time ordering of development. The logical flow is from molecular foundations, cardiovascular sufficiency, body control, external object control, and ultimately mastery and application. This model has greatest utility in analyzing athletes’ shortcomings or difficulties.We don’t deliberately order these components but nature will. If you have a deficiency at any level of “the pyramid” the components above will suffer.
