3. Progressive Resistance Training As mentioned in the previous article: Your bodymass directly influences your resting metabolic rate. The more mass you have, the more calories your body needs to function. When you lose weight, your requirement for calories decreases in tandem. The other side of this coin is that the higher the proportion of muscle mass to fat mass you have, the more calories your body needs: the higher your metabolism. Any weight-loss program that fails to include progressive weight-training is destined to fail long-term by not attempting to combat the reduction in metabolism due to reduction in body-mass. Weight-training places necessary demand on the muscles to grow, or at least maintain mass. POINT A: So you need to weight-train, OK. But is all weight-training hypertrophic (muscle-building)? Yes and no.
POINT B: So squatting 150lbs x 30 reps is obviously the most effective choice here. But if I just squat 150lbs x 30 reps two times per week for the next year, will I see steady improvement in my muscle-building? Probably not. Why? Adaptation. (click link for Basic Principles of Exercise Training) Your body adapts to the work you do. After 6 weeks of squatting the same weight for the same reps, your progress will have slowed or have begun to slow. How do you combat this phenomenon on exercise physiology? Adapt your training. Example... Week 1(A): 150lbs x 6 reps x 5 sets = 4500lbs Week 2(A): 150lbs x 6 reps x 6 sets = 5400lbs Week 3(A): 150lbs x 8 reps x 4 sets = 4800lbs Week 4(A): 150lbs x 8 reps x 5 sets = 6000lbs Week 1(B): 160lbs x 6 reps x 5 sets = 4800lbs Week 2(B): 160lbs x 6 reps x 6 sets = 5760lbs In this example, the total weight lifted progressively increases in a wavelike fashion, undulating upwards then downwards, then back up again a little higher. This is (one form of) progressive resistance that takes advantage of the hypertrophic effects off increasing intensity/load, as well as the gradual increase in volume. The wavelike periodization is ideal for preventing chronic maximum stress. If going "all out" each workout you inevitably create a deficit in recovery, which impedes progress. So even though there are many ways we may use resistance and weights in our training (see picture above), it doesn't mean that these are effective methods of muscle building or even muscle maintenance. Because, like your caloric requirements, the stimulus required to trigger muscle growth is a moving target. Changes in our bodyweight, our age, our environment, and even our sleeping behaviour can all affect how efficiently we build muscle.
The Journal: Just like how you track your food, you should be tracking your training volume. If you have someone special to create a program that is progressive by design, much of that work is done for you. However, you should still keep a journal to make notes as to what weights are appropriate, energy level, instances of pain, any exercise modifications, or modifications based on how quickly or slowly you're progressing.

#2: Carefully Controlled Calorie Intake When all other variables are accounted for, calories drive fat-loss and weight-gain. The first law of thermodynamics is an expression of the principle of conservation of energy. It states that energy can be transformed (changed from one form to another), but cannot be created or destroyed. Our bodies take in energy (food) to perform work (measured in joules or converted to calories spent). But as you can see, not all food calories are used to perform physical work. Sometimes the kcal from your food is:
Does this mean that for some reason the first law is being broken? That the energy going in is out of balance with the energy coming out? No. What it means is that YOUR BODY IS NOT A CLOSED SYSTEM, and it RESPONDS AND ADAPTS to its environment and the stresses placed on it. A VERY IMPORTANT LESSON: "Fat burning" and "increased metabolism" are somewhat opposing terms. I know you've heard ads for products that claim to "stoke your metabolic fire" so you can "burn off fat". My advice: don't waste your money. Here's why:
Your bodymass directly influences your resting metabolic rate. The more mass you have, the more calories your body needs to function. When you lose weight, your requirement for calories decreases. The other side of this coin is that the higher the proportion of muscle mass to fat mass you have, the higher your metabolism. What does this tell us? Any weight-loss program that fails to include progressive weight-training is destined to fail long-term by not attempting to combat the reduction in metabolism due to reduction in body-mass (other social strategies and meal planning options are necessary to combat this as well). Weight-training places necessary demand on the muscles to grow, or at least maintain mass. One of the most crucial elements of exercise physiology that goes ignored by endurance athletes who rely solely on endurance exercise to manage their weight is that the aerobic energy system actually uses 3 fuel sources (simplified):
Aerobics oxidize fat, but they also eat up muscle tissue. This is generally not an issue if you eat a moderate to "high" protein diet, along with refraining from training in fasted states (glycogen depleted), and if you incorporate progressive resistance training at sufficient intensities to stimulate muscle protein synthesis (MPS). Unfortunately, many endurance athletes I know rarely meet their minimum protein requirements, let alone that needed for athletes (1.2-1.8 g/kg bw/day). Their A) calories are often too low and B) carb intake to high to justify the a) distances they cover and b) how low their average intensity is. But that's a story for another time. Bottom-line: the "fat-burning zone" is meaningless if you are overeating calories. If your goal is to lose weight you must create a caloric deficit by consuming less calories than your body needed that day. You can do this by eating less, or exercising more, or both. What you DON'T want to do is train more and more and more while eating less and less and less. This is one form of what I call "spinning your wheels". It's kind of the parallel equivalent of training all the time but eating whatever you want - both result in running yourself into the ground and getting nowhere fast. Doing the former will provoke your body to adapt by lowering metabolism to deal with the excess work performed in the absence of adequate energy - a survival mechanism. Support your body, don't starve it. "Energy Rules! Energy Conversion and the Laws of Thermodynamics - More About the First and Second Laws". Uwsp.edu. Retrieved 2010-09-12. Klok, M.

When it comes to protein brownies, the popular choice has always been to use beans to impart the chewy, richness we think of when it comes to brownies. I've never liked any of the bean-based brownie recipes I've tried. If you want to make delicious brownies that not only taste amazing but are also packed with protein and fiber - you should use hemp protein! I've always thought that there was a missed opportunity having such an affordable, nutrient rich protein powder without having recipes that didn't taste distinctly...green. Your search is over.
Fuel: we must eat enough to fuel our ability to do things we enjoy Nutrition: we must consider the specific raw components the body requires in response to activity and where the balance lies (E.g. Endurance exercise vs. bodybuilding) Health: is "the optimal interplay of the body's organs". What and how much vitamins and nutrients do I need to avoid deficiencies? What special considerations do I have (i.e. vegan, Celiac, dairy sensitivity, etc.)? Building Muscle: you need a minimum amount of protein to avoid muscle wasting - a health related goal. You need an optimal amount of protein to build lean muscle - a fitness related goal. These are all slightly different criteria, but none of them can be achieved without nutrient dense food. There are no magic foods that provide a blueprint to the perfect body, but a perfect body cannot be built out of gummy bears ;) As adapted from Tom Venuto's book The Body Fat Solution In his best-selling book The Body Fat Solution, Tom Venuto espouses simplicity over novelty and sustainable, real-world solutions to weight-loss and weight-management. Many diets that restrict certain foods, or focus too closely on isolated nutrients, hormones, "magic bullets" are cast aside in favour of simple lifestyle changes. The big picture is "synergy", and your success depends upon a "total-life approach that addresses all of the true root causes of the body fat problem in every area of your life - physical, mental, emotional, and social."
The causes of obesity make it a complex issue, but the physiology of body-fat is actually quite simple. It is nothing more than energy balance. Fat metabolism is an intricate area of study, but "you don't need to understand electricity to light your home, you only need to flip the switch". It's amazing to me that most people I meet know intuitively how to lose weight; they just start eating less. They are correct in their conclusion, but seldom successful in execution. I know I need lumber and nails to build a home (a permit helps too), but that knowledge is useless without the blueprints. I'm here to tell you that you don't need to be an expert to understand these blueprints, you just have to be willing to follow them. In the introduction to his book, Tom remarks on how he built his own physique following a short list of crucial principles.
I will attempt to expand on these points on a weekly basis. |
