GOT SQUATS?

It kills me that so many guys in the gym tend to stay away from training their legs – they procrastinate. When leg day comes around they make up excuses such as, “bad knees”, “bad back”, or, “I don’t want to bulk up – I am looking for more definition”.

Here’s the truth: a properly executed squat will help you benefit drastically from bad knees since it will help strengthen the muscle around the knee joint and increase the stability. The same goes with having a bad back – when properly executed the squat will strengthen the supportive tissue throughout the back and spine.

For those who say they are not looking to bulk up in the legs and they would prefer to perform leg extensions or legs curls, or use abductor-adductor machines to obtain more definition, forget it. You will only bulk up if you are consuming enough calories to do so.

Some benefits to performing squats are: increased bone density, an increase in core strength, increase in stamina and an increase in lower body strength and stability.

Another good reason that you should perform squats is to increase the anabolic hormone testosterone. Testosterone allows you to build lean muscle, reduce body fat, improve mood, and increase sexual performance. If you are stuck at a plateau on your bench, there’s a good chance hitting some good squats will elevate your testosterone enough to break it.

If you are not sure how to perform a squat properly, speak to a certified personal trainer and have him or her go over the movement. Even if you think you know how to perform a squat, I suggest you have a qualified individual take a second look to make sure you are performing it correctly.

Make sure you have a good warm-up and stretch before performing squats. I prefer to do my cardio at the end of my leg workout, as the increase in oxygen will help eliminate the build-up of lactic acid – the burn. Finally, take the next 10-15 minutes for a good stretch.

So, don’t forget about your squats and remember: procrastination is just like masturbation – it seems like a good thing at the time, but in the end you’re only fucking yourself.

VITAMIN C - don't forget about it.

It is commonly known that vitamin C is a powerful nutrient. Mainly due to its ability to prevent colds and keeping you scurvy free. But, it’s lesser known benefits are those that can help you be a better bodybuilder.

Plasma ascorbic acid, vitamin C in your blood, has been shown to have an inverse relationship to degenerative joint pain and osteoarthritis. This is because vitamin C is needed for collagen synthesis and the repair of it. What does this mean to you? It means it can help reduce the pain, or prevent the pain that you get from doing heavy compound movements like squats.

It has also been shown that a person low in vitamin C can have more trouble burning fat. This is because vitamin C is needed for the formation of carnitine, a biological molecule needed for adipolysis, the metabolism of fat tissue. So take your vitamin C supplementation seriously and watch how the addition of it can change your performance.

My SND Experience.

This past weekend Sport Nutrition Depot and Popeye’s Supplements across Ontario, Canada had their Customer Appreciation Day. I was lucky enough to be in the Waterloo, SND location on Saturday and WOW – the service was great! The last experience that I had of this type of service was when I attended the Mr. Olympia in the adult fun park of Las Vegas. For those of you who have ever attended one of their stylish nightclubs you will know what I am talking about. You walk in and this big-ass doorman greets you with a smile and asks where you would like to sit and even takes your coat – gets the waitress over to you and the drink is in your hands minutes later. Well this is what it felt like walking through the door at Sport Nutrition Depot in Waterloo. The big-ass doorman opened the door, gave me a greeting, and cleared the path through one hell of a line-up that can’t be described, and I took care of my business. A killer experience!

Reasons and Methods for Improving Grip Strength

There are some very valid reasons why an individual would want to improve grip strength:

1) Boost one’s ego – a bit shallow, yes.

2) Will provide symmetry to a physique, so your biceps and triceps don’t over power the forearms in a pose.

3) Perhaps most importantly, help you lift more weight on certain exercises such as dead lifts and rows, and this can potentially help you achieve insane numbers.

The methods for improving grip strength are numerous, but they all encompass one aspect - don’t neglect your forearms in the gym! Thankfully, a variety of methods are available on how you can train your forearms. You can add hammer curls, which would hit both your forearms and biceps. Or superset reverse wrist curls and wrist curls using a thick barbell. All of this can be done the same day you hit your biceps, or even back. Another method is using a kettle bell, which is an old school version of the dumbbell and always one to do a single exercise with one apparatus. To view some different exercises using a kettle bell and improving grip strength, check out this great article on Bodybuilding.com.

www.bodybuilding.com/fun/jasonbrown2.htm

Often people ask if it’s all right to use wrist straps in the gym. In my opinion straps should only be used under certain conditions and should not be used for every exercise, or if it neglects your back training. Say you burned out your grip doing a few sets of heavy dead lifts, and your grip is the failing out point. Now would be a good time to use straps – preferably chalk, however, only if your gym allows it.

NAC Linked to Hypertension

N-Acetyl L-Cysteine (NAC) is an amino acid that has been shown to increase the levels of the antioxidant glutathione. The antioxidant can reduce cell damage, speed recovery from injury and aid muscle growth. The anabolic effect of NAC on muscle tissue makes it a popular supplement for bodybuilders who want to gain lean muscle size and strength.

However, I came across a recent article, which was published in the Journal of Clinical Investigation examining the effects of NAC. The study indicated that the antioxidant properties can form a red blood cell-derived molecule that makes blood vessels think they are not getting enough oxygen. This can lead to pulmonary arterial hypertension (PAH), which is a condition characterized by high blood pressure in the arteries carrying blood to the lungs.

I have used N-Acetyl L-Cysteine for a few years now at 1500mg daily and consider it a foundation supplement for antioxidant purposes and will continue its usage. However, the recent article published in the Journal of Clinical Investigation should not be taken lightly and if you have any concerns about taking this supplement to discuss it with your doctor first.

Biological Functions of Amino Acids

General Overview of Amino Acids

The most common purpose of protein we know of is for its purpose to help repair damaged muscle tissue after a workout. Protein has other functions, such as: aid in the transport of oxygen to tissues; play a role in immune function, so we don’t get sick; help control our mood. All of these doings are possible by the basic building blocks of protein, amino acids.

There are over twenty different amino acids, each one with a specific function in a physiological system. There are many ways of categorizing them. The most common way of sorting them is into categories: essential, conditionally essential and non-essential amino acids.

Essential amino acids are those that the body cannot synthesize, or it cannot create enough of. So it must be consumed via diet.

Conditionally essential amino acids are amino acids that are not always needed, but in certain individuals they are. Such as: a young and growing individual, or during illness.

Non-essential amino acids are just that. The body can synthesize enough of it to maintain normal function, so it does not need to be consumed through diet.

Essential Amino Acids Functions

Histidine

• A precursor of histamine, a compound released by the immune system when an allergic reaction occurs.
• Needed for the repair and growth of tissues. As well as the maintenance of the myelin sheath that is found in the neuronal cells.
• Needed for the creation of red and white blood cells. Helps produce gastric juice in the stomach, aiding in digestion.

Isoleucine

• Helps aid in the recovery of muscle tissue after physical stress (i.e. working out).
• Used in for formation of blood clots.
• Synthesis of hemoglobin.

Valine

• Has a stimulating effect for muscle metabolism, repair and growth of tissue.
• It is a BCAA, can be used as energy source in muscle tissue, and doing so prevents the use of muscle glucose.

Leucine

• A BCAA that prevents the breakdown of muscle tissue.
• Maintains and regulates the blood-sugar tissues.
• Aids in the growth and repair of muscle tissue and bones.

Lysine

• Required for the bone development in children.
• Needed to produce antibodies, hormones, enzymes, and the repair of tissues.
• Assists in calcium absorption.
• Maintains a correct nitrogen balance, and maintains a lean body mass.

Methionine

• Aids in the breakdown of fats.
• Acts as an antioxidant.
• Used in the formation of creatine in the body.

Phenylalanine

• Helps elevating mood.
• Aids in memory and learning.
• Has been used as an appetite suppressant.

Threonine

• Required to maintain a proper balance of protein in the body.
• Assists in the formation of collagen and elastin in the skin.
• When combined with aspartic acid it has lipotropic functions.
• With the aid of methionine assists in immune function by producing antibodies.

Tryptophan

• Required for the biosynthesis of niacin (vitamin B3).
• Used to produce serotonin, an important neurotransmitter, which is important in sleep.

HOW CREATINE IS MADE

Many bodybuilders are unaware of how supplemental creatine is made or even where it is derived from – natural sources or synthetic sources. I will shed a little bit of light on this subject.

Naturally, creatine is produced in our body from the combination of 3 amino acids – glycine, arginine and methionine also chemically known as a-methyl-guanidinoacetic acid. Creatine can also be found in animal and fish sources but extracting large enough amounts for commercial use would be very impractical as it would be quite expensive.

This leads to me to discuss how the creatine we supplement with is produced. The creatine that we consume is synthetically produced by the manufacturing of 2 chemicals – sarcosine, which is a sodium salt and derivative of acetic acid, and cyanamide, which is an organic amide not to be confused with the similar sounding poison cyanide. Although these are chemicals, at the end of their reaction process is a product that is perfecting fine for human consumption – creatine. Reacting the chemicals sarcosine with cyanamide in a specific amount of water, inside a glass-lined filled vessel known as a reactor is the only way to make synthetic creatine.

Just for an example of how chemicals can be combined for human consumption let’s take a look at table salt. Sodium is pretty much safe to consume in its raw form but chloride is toxic to humans and will burn the skin. This is why it was used during WWI. Chemistry has allowed sodium and chloride to be combined into a new and harmless compound – common table salt.

The process for synthesizing creatine has been the same for many, many years and has not changed. The only thing that may have changed is the advancement in technology, which has improved the process, is regards to quality of the finished product.

The process to manufacturing creatine happens in 4 stages – reaction phase, cleaning phase, drying phase, and the milling phase. At the end of this process is a pure finished creatine ready to be packaged. Pure finished creatine is usually 88% creatine and 12% water because creatine picks up and bonds to water molecules during the initial reaction process.

This, my friends is how creatine is manufactured or ‘synthesized’. Later on we will discuss the brand of creatine – PURPLE•K and why bodybuilders consider it a staple supplement in their bodybuilding program.

TRAINING LAWS

When you go to the gym and train, it is a very systematic process, essentially all one does is lift, push, pull the weights. However, it is damn enjoyable. When one is training, there are certain principles one should consider when heading off to the gym or going for a run.

Law of Overload

The principle of overload is perhaps one of the most important and obvious concepts - if one does not push themselves harder (i.e. lifting more weight with proper form, running further) the body has no need to adapt, and thus one will not make any desirable gains in strength and/or endurance.

One can ‘overload’ themselves by adjusting one of the following:

• Frequency – how often
• Duration – how long
• Intensity – how hard

Law of Reversibility

Simply stated, “If you don’t use it, you will lose it”. If you are not training consistently, the body has no need to adapt. So the gains that you have made in the gym will slowly start to relapse.

It is also important to note that one shouldn’t train so frequently that the body goes into a state of over training. Rest is needed for the body to recover.

Some symptoms of over training:

Irritability and moodiness
Altered sleep patterns
Loss of appetite
Loss of motivation or competitive drive
Persistent muscle soreness that does not go away
Fatigue not relieved by rest
Increased incidence of minor illness or injury
Principle of Variety

Doing the same thing over and over again gets boring rather quickly. Incorporating different exercises for each body part will keep your body guessing, and not grow accustomed to the routine you are using. Instead of doing low rep squats; try doing light weight 20 rep squats. Or instead of barbell shrugs, try dumbbell shrugs.

Law of Specificity

The exercise or training that you do will elect a certain and specific response and adaptations. Specific anaerobic exercise stress (i.e. strength-power training) induces specific strength-power adaptations; endurance exercise stress elects a specific aerobic system adaptations. There is only a limited interchange of benefits between strength and cardiovascular training.

So if you have a single goal in mind, train specific for that goal and not something else. If you want big legs don’t go continually training biceps.

Law of Individuality

Everyone is different. Different training routines affect each person in a different way. Some people will respond very well to high reps and light weight exercises, while others will only respond to heavy weight and low rep exercises. So if someone says “You have to try this new routine, it worked wonders for me.” Feel free to try it out, but don’t get disappointed if it doesn’t work out for you.

Kurt Kuhn - www.FUSIONBodybuilding.com

The ATP-PCr System and Creatine

High intensity exercise of short duration (ie.100m dash, 25m or heavy ass squats) requires an immediate energy supply. This comes almost soley on banked stores of intramuscular, high-energy phosphates, phosphagens, adenosine triphosphate (ATP) and phosphocreatine (PCr). Each kilogram of skeletal muscle (the kind of muscle you use when you workout) contains 3 to 8 mmol/l (millimoles/litre) of ATP and 4–5 times more PCr. For a 70kg person, with a muscle mass of 30kg, this represents between 570 to 690 mmol/l of high-energy phosphates. Assuming that 20kg of muscle becomes active during “big-muscle” exercise, sufficient stored phosphagen energy can supply energy for 5-8 seconds of sprint running for 5–8 seconds, or up to 15 seconds of heavy, maximal effort weight lifting.

All sports use the high-energy phosphates, but many depend almost entirely on this means of energy transfer. For example, success in football and the gym requires brief but maximal efforts during the performance. Sustaining exercise beyond a brief period and recovering from all-out effort requires an additional energy source to replenish ATP. If this does not occur, the “fuel” supply diminishes and high-intensity movement comes to a screeching halt. The carbohydrates, fat, and protein found within the cellular fluids and tissue depots remain ready to continually recharge the available pool of high-energy phosphates to sustain muscular activity. However, there are other methods of help maintaining this energy currency. This is where creatine comes into play.

When creatine is consumed it passes through the digestive tract intact and eventually gets shuttled into skeletal muscle. About 40% exists as free creatine; the remainder combines with a phosphate molecule to form PCr.

PCr also shuttles intramuscular high-energy phosphate between the mitochondria and muscle filament cross-bridge sites that initiate muscle action. Maintaining a high ratio of ATP:ADP (adenosine diphosphate) ratio is important for maximum effort activities lasting up to 3-15 seconds. This exercise duration places high demands on ATP re-synthesis that exceed the energy transfer from intracellular macronutrient breakdown.

Generally speaking, creatine has the potential to accomplish the following:

- Accelerate ATP turnover to maintain power output during short-term muscular effort

- Delay PCr depletion

- Diminish dependence on anaerobic glycolysis and decrease resulting lactate formation

- Facilitate muscle relaxation and recovery from repeated bouts of intense, brief effort via faster ATP and PCr resynthesis; rapid recovery allows continued higher level power output

RAZBERI-K - A SUB•Q INNOVATION

Razberi-K, also known as 4-(4-hydroxyphenyl) butan-2-one, is a ketone unique to red raspberry. Raspberries contain many bioactive constituents beneficial for health. One particular constituent, 4-(4-hydroxyphenyl) butan-2-one appears to have the potential to decrease body fat.

A recent study in Sarasota, Florida of this year adds to existing clinical research in which raspberry ketone has been shown to have anti-obesity effects by altering lipid metabolism, specifically by increasing norepinephrine-induced lipolysis, an effect which may enhance thermogenesis and oxidation of body fat.

The chemical structure of raspberry ketone is similar to that of capsaicin and synephrine. Both of which are well documented for their ability to produce thermogenesis through the release of norepinephrine. However, there are health risks with these two ingredients – synephrine has been shown to have dangerous cardiovascular side effects, while capsaicin has been shown to cause gastrointestinal distress in many users. There are no documented side effects related to raspberry ketone consumption.

This revolutionary ingredient is part of the Beyond Ripped Complex™ found exclusively in SUB•Q.

The Human Nervous System - PART THREE

The Autonomic Nervous System Divisions

The autonomic nervous system (ANS) houses two major divisions, the parasympathetic and the sympathetic division. At most times, the two divisions are antagonists to each other; if the sympathetic division causes excitation, the parasympathetic division will counter-act with an inhibitory effect. This is not always the situation, however. Because the two divisions may work independently, with some structures innervated by one division, and the two divisions may work synergistically, each contributing to one stage of a complex process. Generally speaking, the parasympathetic division is active in rest states, and the sympathetic division “kicks in” during times of exertion, stress, or emergency.

When you are doing a heavy weight lifting session at the gym your sympathetic division is full effect. It is sending signals to your cardiovascular and respiration center of the pons, leading to increased blood pressure, heart rate, breathing rate and depth of respiration, so blood and oxygen delivered to muscles. All of this happens unconsciously; it is and is an involuntary action. During this time also, your digestive system is somewhat inhibited so all of ones energy can be focused at the task at hand. One will also have an increased mental alertness and a state of euphoria. Also, there is a general elevation of muscle tone, so a person looks tense. Finally, the mobilization of energy stores, through an increased breakdown of glycogen in muscle and liver cells and the release of lipids from adipose tissues.

After the workout or cardio session the activity of the sympathetic nervous system decreases and the parasympathetic division comes into play. When you leave the gym and step out into the bright sun (hopefully) the parasympathetic nervous system will cause a constriction of the pupils to inhibit the amount of light entering the eyes. And while on your way back home or wherever, there is secretion of digestive glands, including of hormones that promote nutrient absorption, so the hard worked muscles can recover properly. There is also a constriction of respiratory passageways and reduction in heart rate and force of contraction. All of this aids in you becoming more relaxed.

Like stated, the parasympathetic nervous system focuses on relaxation, food processing and energy absorption. It ahs been called the anabolic system because stimulation leads to a general increase in the nutrient content of th blood.

The Human Nervous System - PART TWO

The Central Nervous System - The Spinal Cord

The spinal cord attaches to the brainstem providing a critical pathway for the flow of information from the skin, joints and muscles to the brain, and vice versa.

In cross sections of the spinal cord there is a H-shaped center of gray matter. The ventral (anterior) and dorsal (posterior) horns describes the sections of this core. The spinal cord core contains primarily three types of neurons: motor neurons, sensory neurons, and interneurons. The motor neurons (efferent) run through the ventral horn to supply skeletal muscle. Sensory (afferent) nerve fibers enter the spinal cord from the periphery by way of the dorsal horn. The white matter, containing the ascending and descending nerve tracts, surround the gray matter within the cord.

As previously mentioned, information going towards the brain is sensory information, such as touch, taste and also pain. So if you are working out and pull a muscle or drop a 45 lb plate on your small toe the nerves will travel up to the brain via afferent nerve fibers of the spinal and the information will be integrated there. Here the response will be traveling via afferent nerve fibers to produce a motor response.

Ascending Nerve Tracts

Ascending nerve tracts in the spinal cord send sensory information coming from peripheral receptors to the brain for processing. There are three neurons that typically make up sensory pathway.

1) The dorsal root ganglion contains the cell body of the first neuron whose axon relays information into the spinal cord.
2) The cell body of the second neuron lies within the spinal cord itself; its axon passes up the spinal cord to the thalamus.
3) The thalamus contains the third neuron's cell body. The axon of the third neuron passes up to the central command center of the cerebral cortex

Descending Nerve Tracts

Axons from the brain move downward through the spinal cord along two major pathways. The lateral or pyramidal tract activates the skeletal muscle (the muscles that you primarily use when working out). The second pathway named ventromedial or extrapyramidal tract, controls posture and muscle tone via the brainstem.

Kurt Kuhn - www.FUSIONBodybuilding.com

The Human Nervous System - PART ONE

Divisions of the Nervous System

The human nervous system has two major divisions:

1) The Central Nervous System (CNS) which is made up of the brain and spinal cord.

2) The Peripheral Nervous System (PNS) division that contains nerves that transmit information to and from the CNS.

From there the PNS is divided into the autonomic nervous system (ANS) which controls involuntary information and it conducts impulses from the CNS to cardiac muscle, smooth muscles (ie. digestive system), and glands. The ANS then gets divided into the sympathetic and parasympathetic nervous system which will be discussed later.

The other partition of the PNS is the somatic nervous system which conducts impulses from the CNS to skeletal muscle.

Both of these divisions play an important role to bodybuilders. It allows us to lift heavy ass weights and digest much needed food.

Breakdown of the Nervous System

The Central Nervous System - The Brain

As previously mentioned the CNS is made up of the brain and spinal cord. The CNS is responsible for integrating, processing, and co-ordination sensory input and motor output. It also plays a role of higher functions, such as intelligence, memory, learning and emotion.

The brain is divided into numerous regions which include the brainstem, cerebellum, diencephalon, telencephalon and the limbic system.

The Brainstem

The brainstem is made up of the medulla oblongata (medulla for short), pons and midbrain. The medulla oblongata is important for relaying sensory information to the thalamus and to other brainstem centers. Also, it contains major centers concerned with the regulation of autonomic function, such as heart rate, blood pressure and the digestive activity. Which all play an important role in the world of gym, the medulla can increase our heart rate so much needed oxygen gets delivered to the muscle and adjusting of blood pressure so we don't faint.

The pons relays sensory information to the cerebellum and thalamus. Also, it is contains subconscious somatic and autonomic motor center. Any motor movements that we don't think about will be sent here.

Cerebellum

The cerebellum functions by complex feedback circuits that monitors and coordinates other areas of the brain and spinal cord that are involved in motor control.. The cerebellum receives motor output signals from the central command in the cortex. This cerebellum, also obtains sensory information from peripheral receptors in muscles, tendons, joins and skin and from visual, auditory, and vestibular end organs. The cerebellum serves as the major comparing, evaluating, and integrating center for postural adjustments, locomotion, maintenance of equilibrium, perceptions of speed of body movement and other diverse reflex functions related to movement. Movements that are first learned by trail and error, like riding a bicycle or proper form of deadlifts or squats, remain coded as coordinated patterns in the cerebellar memory banks. Essentially, this motor control center ?fine tunes? all forms of muscular activity

Diencephalon

The diencephalon is made up of the thalamus and hypothalamus. The thalamus provides the switching and relay centers for both sensory and motor pathways. Ascending sensory information from the spinal cord and cranial nerves (other than olfactory nerves) is processed in the thalamus before the information is relayed to the cerebrum or brain stem. The thalamus also plays an important role in regulating a sleep and wakefulness states and also has a role in controlling arousal, the level of awareness and activity.

The hypothalamus which lies inferior to the thalamus in the cerebrum, controls metabolic and body temperature. It also influences activity of the ANS; it receives regulatory input from the thalamus and responds to the effects of diverse hormones.

Telencephalon

The telencephalon contains the two hemispheres of the cerebral cortex which makes up approximately 40% of the total brain weight. It is divided into four lobes; front, temporal; parietal and occipital. Neurons in the cortex provide specialized sensory motor functions. Deep to each cerebral hemisphere and in close association with the thalamus lie the basal ganglia, which play an important role in control of motor movements.
