For most strength and conditioning experts, the answer is yes, but there is another point of view worth understanding. The purpose of all strength training for athletes is to improve athletic performance and building lower body and core strength is key for almost all athletes. Conventional practice is that the barbell back squat is THE way to develop lower body strength.

Breath Training for Improved Physical and Mental Performance
Breathing involves the exchange of oxygen (O2) and carbon dioxide (CO2). When you inhale you get oxygen, and when you exhale you blow off excess carbon dioxide. Inhalation is triggered by rising levels of CO2. Therefore, if you are overly sensitive to CO2 you will breathe harder and faster than someone who is not.
By reducing
your sensitivity to CO2, you can increase tissue oxygenation, breathing
efficiency and athletic performance. One of the best ways to do this is by
practicing controlled breath holding and nose breathing.
Done
properly these exercise change levels of O2 and CO2 in the blood which creates
hypoxia and hypercapnia.
What is
Hypoxia?
Hypoxia refers
to lower oxygen levels in the tissues of the body. Severe and/or prolonged hypoxia is obviously
dangerous. However controlled levels
of hypoxia actually drive improved tissue oxygenation in an adaptive response
to this challenge!
What is Hypercapnia?
Hypercapnia refers
to excess carbon dioxide (CO2) in the blood. This can happen for several
reasons, including:
Breathing
disorders such as sleep apnea
Severe
asthma attacks
Heart
problems causing reduced blood flow to the lungs
Poor liver
function
Kidney
failure
When
hypercapnia occurs, the body compensates by increasing heart rate and breathing
rate. If hypercapnia is severe and prolonged it can lead to serious issues
including coma and death. However
controlled and short-term levels of hypercapnia can actual drive improved
tissue oxygenation along with Hypoxia.
Benefits of controlled and short-term Hypoxia and Hypercapnia
Both hypoxia
and hypercapnia training can improve endurance, increase the amount of oxygen
your body can use, and help protect muscles from damage. In addition,
hypercapnia training can improve your strength, power, and sprint performance.
Both forms
of training have been shown to be safe and effective in several sports when
done properly.
How does
this work?
All physical
training produces a physiological challenge which drives an adaptive response
during recovery from the training challenge, and this definitely includes Hypoxic
and Hypercapnia Training!
Mechanism
of Action
Oxygen is
primarily carried by hemoglobin in red blood cells which transports it to the
tissues of the body, and transports CO2 to the lungs to be exhaled. The affinity of hemoglobin for 02 changes
based on pH (acidity), temperature, and CO2 levels and is described as the
Oxy-Hemoglobin Disassociation Curve as pictured below.
During ANY Type of exercise, the muscle get more acidic, temperature increases and there is increased CO2 production - which means that higher levels of 02 are automatically off-loaded to those tissues!
Because athletes and regular exercises go through this process over and over again they have a much greater tolerance for CO2 levels. In fact, a study found that athletes have significantly higher tolerance for CO2 levels and for any given amount of exercise athletes experienced 50 – 60% less breathlessness than untrained people did!
In addition,
increasing levels of CO2 in the body (including the brain) cause increased
production of Nitric Oxide (NO) which opens blood vessels to allow higher
circulation.
How to
Incorporate Breath Training into your Workouts
The easiest
way to start this process is by deliberately making an effort to breath through
the nose – starting at rest and then during exercise. By breathing through the nose you will train
your breathing muscles to become stronger.
In addition your nose helps filter impurities out of the air so they do
not reach the lungs – including viruses!
Nasal breathing also reduces incoming O2 levels and results in higher
levels of CO2. This provides a very
real conditioning effect and over time you will become more and more accustomed
to higher levels of CO2 which can actually boost O2 levels in the tissues.
CAUTION: use common sense – start slow and low with nasal
breathing and if you have a nasal obstruction do NOT use nasal breathing.
The other
exercise is controlled breath holding exercise. Start at rest and note how many seconds you
can go until you experience a strong urge to breath – then BREATH! Over time gradually increase your time as
you notice you can do so without experiencing a strong urge to breath.
Once you get
comfortable and experienced you can graduate to doing the same type of breathing exercise
during light exercise.
CAUTION: Anyone with any breathing issues including
but not limited to Asthma, Chronic Obstructive Pulmonary Disease, high blood
pressure, heart disease or other disease process should NOT perform these
exercises! We also always recommend you
speak to your physician before starting this or any other new exercise program.

Swimming = Big Benefits for the Brain!
It’s no secret that cardiovascular exercise can help slow down some of the worst aspects of aging, but research suggests that swimming provides a unique boost to brain health.
Regular swimming improves
cognitive function, memory, mood, and immune response. Swimming may also help mitigate damage from
stress and create new neural connections in the brain.
Aerobic Exercise and New and improved brain cells and connections
There is research proving
that aerobic exercise improve neurogenesis (creation of new neurons aka brain cells) and
help reverse and repair damage to brain neurons and their connection in both
mammals and fish.
These benefits come in
large part through higher levels of Brain Derived Neurotrophic Factor or BDNF
for short. The neural plasticity, or ability of the brain to adapt is
stimulated by BDNF. BDNF acts like
Miracle Grow for the brain and is proven to boost cognitive function including memory
and learning.
Research in humans shows a
strong relationship between BDNF levels and increases in the size of the
hippocampus area of the brain which is responsible for learning and memory. BDNF has also been shown to help alleviate anxiety
and depression. In contrast, research
has shown that lower BDNF levels are linked to mood disorders in humans.
But what’s special about swimming?
Researchers are not sure what
swimming’s secret sauce might be. But they’re getting closer to understanding
it. Because swimming involves all of the
major muscle groups, the cardiovascular system increases blood flow which leads
to many benefits including the creation of new blood vessels known as
angiogenesis. The greater blood flow can
also lead to a big boost of endorphins that act as a natural pain reducer
throughout the body. This surge is one
factor linked to the sense of euphoria that often follows exercise.
In addition, by its very nature swimming involves breathing stress and increased levels of carbon dioxide (CO2) tolerance as you hold your breath between strokes. This creates mild hypoxia (lower blood oxygen) and hypercapnia (higher levels of CO2). This gentle stressor results in positive adaptations in the circulatory system including increase oxygen carrying capacity. In addition improved tolerance of CO2 is very helpful for anxiety.
Although most studies on
swimming and brain function have been done in animals, research in people shows
similar results suggesting a clear cognitive benefit from swimming at all ages.
For instance, in one study looking at
the impact of swimming on mental acuity in the elderly, researchers concluded
that swimmers had improved mental speed and attention compared to non-swimmers.
Kids Also Benefit!
The brain-enhancing
benefits from swimming boost learning in children. Researchers found that
children’s accuracy was much higher for words learned following swimming
compared with coloring and CrossFit, which resulted in the same level of
recall. This shows a clear cognitive benefit from swimming versus anaerobic
exercise, though the study does not compare swimming with other aerobic
exercises. These findings imply that swimming for even short periods of time is
highly beneficial to young, developing brains.

Choline - The Most Important Nutrient You Never Hear About!
Choline is a nutrient needed for the brain to produce a key
neurotransmitter called acetylcholine. Acetylcholine
is synthesized from choline and involved in memory, circadian rhythm and muscle
control. Each of these specific functions contribute to the impact it has on
cardiovascular health, liver diseases, neural tube defects and cognitive
health.
There are synapses between nerves throughout the brain that
rely on acetylcholine to communicate. Scientists have found using drugs that
inhibit levels of enzymes that break down acetylcholine increases acetylcholine
in the brain, and this has proven useful in the treatment of Alzheimer’s
dementia.
Further many drugs, including most over the counter allergy
medications, have an anticholinergic action meaning they cause decreases in
acetylcholine. Research has proven that
regular intake of these medications increases the risk of dementia in people 55
years and older.
To make matters worse studies have show that up to 90% of US
Citizens have a choline deficiency.
When you combine deficient choline intake from diet with commonly used
drugs that deplete acetylcholine you set-up the perfect storm for dementia! The good news is that with targeted eating
or supplementation it is easy to take in adequate choline levels to help
prevent dementia!
There are several foods with high levels of choline. The food with the highest level of choline
is liver with a whopping 356mg per 3 ounces.
Another food with high levels is egg yolks. Beef, seafood, and poultry are also good
sources of choline. Unfortunately, many
of these foods, such as egg yolks, have been unfairly demonized and incorrectly
connected with causing high blood cholesterol. This is NOT the case! One egg yolk contains
about 130mg of choline which is 25% - 30% of your daily requirement.
For adults the daily requirement is 400mg for female and
545mg for males.
Choline Supplements
Another way to ensure adequate choline intake is to supplement. There are four types of choline
supplements. Plain choline and choline
bitartrate are the least expensive but does not support production of
acetylcholine as well as DFP-choline aka citicoline or Alpha GPC choline.

How Many Repetitions per Set?
Many hours are spent in heated debate on this topic, but
the truth is that the number of reps per set and number of sets per workout are
secondary measures. A review of the scientific research shows
that the weight of evidence does NOT support the idea that different numbers of
repetitions have differential effects on muscular strength and
endurance.
Furthermore, a review on this subject concluded that “all these studies strongly suggest that within a reasonable range of repetitions, approximately 3 to 20, there does not appear to be a specific number of repetitions that will elicit more favorable gains in muscular strength, power or hypertrophy.”
What does matter then? It is ALL about reaching momentary muscular failure - meaning that you cannot complete another repetition of an exercise in good form. If you do not reach muscular failure or come very close the reps and sets will not produce results. Perfect form is part of this equation because perfect form means keeping tension in the targeted muscle/s throughout the entire repetition and not using momentum.
For example, allowing the weights being lifted to settle on the top of the weight stack means you are unloading the muscle – NOT what we want to do! Throwing weight using momentum is another way you can deload the muscle. The key is performing smooth, steady repetitions throughout the range of motion for an exercise with no deloading until you reach momentary muscular failure.
For beginners one set to failure between 8 – 15 repetitions is plenty for each muscle group. Over the longer haul repetitive sets become necessary to make progress – but never sacrifice reaching muscular failure and perfect form to do extra sets!

Erectile Dysfunction Medications May Have Significant Cardiovascular Benefits
You heard that right – recent research showed that two popular erectile dysfunction (E.D.) drugs confer cardiovascular benefits to men with concurrent heart disease and E.D. The two drugs – sildenafil and tadalafil (Viagra and Cialis respectively) are both PDE5 inhibitors which widen blood vessels.
In men with heart disease - both Viagra
and Cialis significantly reduced the likelihood of progression to heart
failure, myocardial infarction (MI), and death after 5 years as compared with
men taking neither drug. Cialis had a more pronounced effect on all three
clinical events than did Viagra.
Lead
researcher Albert Ha, MD, of the Columbia University Irving Medical Center in
New York City pointed out that - "Contrary
to what most people believe, PDE5 inhibitors also have been shown to alter
endothelial function and improve myocardial perfusion," he said. "We
know there is data out there suggesting that PDE5 inhibitors lead to cardiac
benefits, including improved cardiac function and possibly microvascular
improvement."
E.D. is very
common among men with cardiovascular disease because both conditions share
issues with endothelial function – meaning the arterial surfaces are compromised
and not functioning properly. In fact, ED is often
one of the first signs of cardiovascular disease.
PDE5 Side
Effects
Like all
drugs these drugs can have side effects and require a prescription. These side effects can include adverse effects
on the eyes in rare cases. However, a
review of a large insurance database showed no consistent association between
PDE5 inhibitor use and ocular events, reported Federico Belladelli, MD, of
Universitá Vita-Salute San Raffaele in Milan.
Another side
effect can be blood pressure that is lowered too much which can occur if men are
also taking other blood pressure lowering drugs such as nitroglycerin.

The Benefits of A2 Milk
You probably
know someone does not drink cow’s milk due to protein sensitivity or concern.
While sensitivities to milk protein exist and should be respected, it’s
important to be aware of the facts about milk as you could needlessly be missing
out on the milk’s many benefits.
A recent
meta-analysis of observational studies and controlled trials dispelled the
common myth that protein found in milk is bad for humans. Researchers concluded
that milk and dairy products are good sources of high-quality protein and that
dairy protein is a source of essential amino acids.
Another
commonly cited problem with milk is lactose.
Lactose
is a sugar in milk that requires the lactase enzyme to break it down. People with lactose intolerance cannot digest lactose
properly. The condition is usually harmless, but its symptoms can be
uncomfortable.
However, in
many cases, the digestive distress some people experience after drinking milk
has nothing to do with Lactose. Instead,
there is a protein found in milk that is often the cause for these
uncomfortable and often embarrassing symptoms.
The Two Forms of Beta-Casein Protein
The protein
in cow’s milk is made up of whey (1 to 2%) and casein (6 to 8%), with the
primary protein known as beta-casein.
Beta-casein
protein comes in two forms, A1 and A2, that affect your body differently. Most
modern-day cow’s milk is a combination of A1 and A2.
Unfortunately,
the A1 protein may cause stomach discomfort.
When A1
protein is digested it produces a peptide called beta-casomorphin-7 (BCM-7). BCM-7 has been linked to stomach discomfort with
similar symptoms to lactose intolerance.
A2 protein is
more comparable to human breast milk, as well as milk from goats, sheep and
buffalo. More natural to the human body, A2 is easily absorbed.
Historically,
cows milk only contained the A2 form of beta-casein. However, over time, a
genetic mutation occurred in cows and resulted in
cows with two types of proteins – A1/A2.
Due to the
genetic mutation that evolved in the cows, A1/A2 milk is here to stay – with
many people unable to enjoy milk’s nutritional properties without frustrating
discomfort.
Fortunately, A2
milk is available. Through selective breeding
a New Zealand company farmers learned to breed cows that only produce the A2 form of Beta
Casein.
A2 Milk has
the4 same nutrition, and creamy, great taste as regular milk and is available
in many stores including Kroger, Walmart, Publix, Safeway, Whole Foods, Sprouts,
Ahold, ShopRite, Wegmans, and Target.
There are
even 100% grass-fed and organic forms of A2 Milk available – just google them!
Since grass –
not grain – is the evolutionary form of food for cows it should be no surprise
that grass fed milk has higher levels of key nutrients. This includes increased levels of Omega 3
Fatty Acids along with conjugated linoleic acid (CLA) which actually helps
reduce bodyfat!.

The Benefits of Grounding - AKA - walking barefoot!
With summer arriving many of us will have the opportunity of walking on a beach in bare feet. It’s not just the sea air, water, and sunshine that makes this so fun. There is a powerful connection formed with the earth when your feet are in direct contact with the ground.
Anyone with small children knows they want to try to ditch their shoes every chance they get – but if you think about this a little you will probably realize that you feel better when you can walk around barefoot. This is particularly true when you can walk directly on the ground safely such as walking on the beach. Researchers have begun to unravel why being barefoot directly on the ground can in fact be very good for your health!
Your immune system functions well when your body has an adequate supply of electrons, which are easily and naturally obtained by barefoot contact with the Earth.
Research has shown that electrons from the ground have measurable antioxidant effects that can protect your body from inflammation. For most of our time on this planet we have been in direct contact with the ground without anything that would block the flow of electrons into our body – natural animal hides do NOT interrupt the flow of electrons!
However in modern time’s pavement, wood, rubber, plastics and many other forms of non-conductive material are between our feet and ground blocking the natural flow of electrons.
The surface of our planet has a negative electrical potential. So when we are in direct contact with it electrons flow to your body through a process called “grounding”. Grounding cause positive physiological effects that promote optimum health.
Specific researched benefits include improvements in blood viscosity, heart rate variability, inflammation, cortisol dynamics, sleep, autonomic nervous system (ANS) balance, and reduced effects of stress.
When you connect directly to the ground without any non-conducting material between you and the electron field of the planet there is an improvement in the balance of two sides of your autonomic nervous system: the sympathetic and parasympathetic nervous systems.
How Shoes May be Impacting Your Health
Materials like metals are excellent conductors of electricity (aka electrons!). The human body is also conductive because it contains a large number of charged ions (called electrolytes) dissolved in water.
Other non-conductive materials, such as plastic and rubber, have very few free or mobile electrons. Traditionally shoes were made of leather, which is a good electrical conductor. However almost all modern shoes contain rubber and plastic which block the flow of electrons from the earth to your body.
The Health Benefits of Grounding
Your immune system body has evolved a method of destroying bacteria and viruses by generating reactive oxygen species (ROS) that are delivered by immune cells. These ROS do exactly what they are designed to do, but they can also cause extensive damage to healthy tissues. ROS are usually positively charged molecules that need to be neutralized immediately to prevent damage to the body after destroying bacteria or viruses. This is one of the key functions of anti-oxidants which are most important in immune cells to protect them from the ROS they generate!
Anti-oxidants essentially provide a supply of negative charges. Food based antioxidants (such as Vitamins C and E) and anti-oxidants your body produces are critical but a regular supply of electrons grounding can supply them as well.
Evolution facilitated the process of grounding by providing conductive systems within your body that deliver electrons from your feet to all parts of your body. This system has been integral to human physiology for thousands of years. Negative electrons are always available, thanks to the Earth, to prevent the inflammatory process from damaging healthy tissues.
All of this was interrupted when we started to wear shoes with rubber and plastic soles, and no longer slept in direct contact with the ground. Several experiments have proven that a person who is grounded is less stressed and more relaxed.
So have some fun, kick your shoes off and get back to nature!
How to get the benefits of Grounding
Grounding is simple in warmer climates – simply spend time barefoot in direct contact with the earth. Even better do this on a beach walking along the edge of the water because the flow of negatively charged electrons will be highest here because sea water is an ideal conductor of electrons! Any amount of time will help but the more you can do it the better! Even better spend some time laying on the beach or ground with your body in direct contact with the ground without any artificial fabrics, rubber or plastic between your skin and the ground.
For those of us who do not live in warm climates staying grounded during colder months is a bit more challenging but doable! There are actually shoes that are specifically designed to facilitate electron flow from the ground into your body like these:
