Tim Ferriss: CrossFit's Good, Bad and Ugly

CrossFit has taken a beating in the general health world as it's popularity has exploded onto the fitness scene in the past couple years.  People either seem to love or hate the Work Out of the Day (WOD) concept and think that the jumping, running, and olympic lifting combination can be too intense or even down right dangerous.

Tim Ferriss is a self proclaimed "body-hacker" and has written some incredible books (Check out The Four Hour Body") to improve your life and has done some great work in the health and performance world.  On his podcast, The Tim Ferriss Show, he has great interviews with top level people in each industry that provides great information.

He interviews Kelly Starrett who owns and operates San Francisco CrossFit (one of first 50 affiliates, now over 2500) and Mobility WOD.  They discuss the benefits and downfalls of CrossFit and where it has been, where it is and where it is going in the future.  This is a great discussion.  Check it out below.

5 Supplements You Shouldn't Train Without

I'm not sure why but it seems like supplements get a bad reputation.  I really find this odd considering how focused the world has become on "quick fixes" and making things easier.  I agree, that if you consume a well-balanced diet and eat the proper ratio of carbs/proteins/fats that you may not need supplements to the same extent as a person who eats 2 meals a day and one of them is fast-food.  However, you could still benefit from supplements.  One of the major reasons is because eating the amount of whole-food it would take to get ample amounts of some of the ingredients found in supplements would be impossible.  A convenience factor is another reason I recommend supplements.  They make it easy to eat exactly what you want, when you want even if you are on the go.

I get asked a lot what I think are the best supplements out there.  I tell people it depends what you're goals are. Are you looking to bet bigger? Stronger? Faster? Improve your 10K time?  Different goals can benefit from different supplements as they each have something to offer. In terms of brands, I'm really not too picky. I usually tell people to shop around for the good deals (i.e. gold card week at GNC or value packs at Sam's Club) as a lot of products have very similar ingredients regardless of where you purchase them as long as it's not from the guy selling protein in the alley behind the gym.  Just make sure they are a high quality brands, meaning they are certified by some form of a governing agency.

1. Protein

Protein is probably the most popular nutritional supplements used regularly by exercising individuals.  The benefits of protein are endless as each individual amino acid that makes up a complete protein has a vital role in our body.  The most popular reason to supplement with protein is probably to help build and maintain muscle mass.  This can have several positive benefits (i.e. higher daily caloric energy expenditure, increased strength & power, improved appearance etc.).  So, in conclusion if you aren't consuming enough protein from your daily diet, I highly recommend including a protein supplement into your daily stack.

2. Creatine

Creatine has repeatedly been shown to help improve performance during bouts of high-intensity exercise as well as strength and power.  Creatine helps provide energy during high-intensity exercise which allows an individual to maintain a higher force output for a longer period of time before fatigue sets in.  This could help someone train at a higher volume over time and leader to greater gains in strength and size.

 3. Caffeine

Everyone is well aware of caffeine and what it can do for you (especially that individual who isn't a morning person and can't get out of bed without their morning java).  However, athletes are beginning to understand there maybe more to caffeine than we originally thought.  Evidence has shown that caffeine can improve short-term strength and power performance during activities such as sprinting, weightlifting and cycling.  Anyone who has ever taken a pre-workout supplement (often times loaded with caffeine) can attest to this.  Also, caffeine can help improve endurance performance by helping increase fat utilization which can spare glycogen (a major fuel source during endurance exercise) and ultimately delay the onset of fatigue.

Is Running Bad For You?!

As I'm sure a lot of you know by now, I am not the biggest fan of running. Up until now, the biggest reason was mainly because I wasn't good at it and it was painful. However, some recent research has surfaced that has given me one more reason to not like running.  A recent article published by a research cardiologist examined life-long runners and their risk of dying from heart related issues.  What he found was actually rather startling....

 

I'm sure most of you (myself included) have always believed that regularly exercise is good for you and will increase your lifespan.  On the flip side, if you sit around all day doing nothing, you probably have a higher risk of developing diseases, particularly cardiovascular disease, and therefore may not live as long.  A recent article titled: "Run for your life...at a comfortable speed and not too far" found some rather contradictory evidence that this may not be the case.  Everyone has probably heard of the individuals who have collapsed and died during/following athletic events or bouts of exercise EVEN THOUGH they were thought to have been in excellent shape.  A lot of these cases are believed to have been caused by underlying genetic conditions (i.e. hypertrophic cardiomyopathy). which is the leading causes of cardiac death in athletes.  However, there may be more to the story.

In the previously mentioned article, it stated:

"High-intensity exercise sessions lasting beyond 1–2 h cause acute volume overload of the atria and right ventricle (RV), which can bring about overstretching and micro-tears in the myocardium, as evidenced by a transient rise in cardiac biomarkers." 

Basically this is saying long-term intense exercise can actually cause damage to your heart. This kind of goes against everything we have been believing for years, right?  The authors did explain that the acute damages seen following the intense exercise does revert itself and things can go back to normal within a few days.  However, they also explained that if high-intensity or high-volumes of exercise are sustained for multiple hours a day for multiple days/months/years (i.e. marathon runners) the damage can add up and actually speed up the "aging" process of the heart!  In the graph below, it shows an individual's risk of dying, dependent on how many miles a week they run  The red bar on the far left represents a sedentary individual who has the highest risk of dying.  On the other end of the spectrum, there are 2 red bars representing people who run 20-25 miles and more than 25 miles a week and they also have a relatively high risk of dying....wait, what?A sedentary person has the same risk of dying due to disease as a life-long marathon runner who is in excellent shape!?

And On The Seventh Day...I Rested

It's that day of the week that every exercise junkie dreads....rest day.

Hi, my name is Andrew Jagim and I am an exercise addict (not me in the picture by the way).  In my eyes, if I didn't work out one day I go to bed worrying that I got a little fatter and probably lost all the muscle and strength I had worked so hard for.  I think this way even though I KNOW this couldn't be further from the truth.

A lot of people fall into the misconception that if a little bit is good, than a lot is better! This can be true for some (i.e. if you weigh 400 lbs than there is no such thing as too much time on the stair climber).  However, for those individuals who try to train/lift/workout all out, give 110%, balls out, day in and day out than you may be  hindering your potential to improve.  It may sound crazy but it's on your off-days that you actually get bigger and stronger.  if you are training at a high intensity, you are actually causing micro-tears and other cellular damage to occur within your muscles.  Just like restoring an old building, sometimes you just have to tear down the old stuff to make room for the new stuff.  In a nutshell, this is how muscle growth works.  You damage your muscles and therefore are essentially forcing to come back bigger and better than before.  So not only is your time in the gym important but so is your time away from the gym.  This is also the reason why you should try to avoid training the same body part/muscle groups on consecutive days as those muscles need proper time to recover.

Proper sleep and nutrition are not only important on training days but they may be even MORE important on your rest days.  You need to make sure you keep your protein intake up in order to support the increasd rate of protein synthesis occuring as a result of your training.  This is especially the case for the weekend warriors who during the week eat right, get a solid 8 hrs of sleep, workout every day and then when the weekend comes around they party for 48 hours, eat like crap and then expect to pick it right up where they left off on Monday.  Then refer to their weekend as their "rest days."  Not only will the extra (and worthless) calories from alcohol likely lead to increases in body fat, research has shown that alcohol can lower growth hormone and testosterone levels which are key players in muscle growth and recovery.  A lack of sleep can also hinder your recovery and can have negative effects that last several days.

One thing I should mention, is that rest days or off-days don't have to consist of 12 hrs of couch time (unless it's football season).  Your off-day can consist of light activities or even your normal exercise routine but just drop the resistance/intensity way down.  This is one thing I'll knock on Cross-fit for.  A lot of their workouts are very intense with little-to-no lower intensity or volume days which can lead to symptoms of over-training if carried out over time.  

So, moral of the story: Train hard and rest hard!

What is HMB and What Can it Do For You???

 

HMB

Hydroxy-beta-methylbuterate or HMB, is a metabolite of the branch-chain amino acid, leucine.  Leucine has been shown to have several positive effects when consumed in conjunction with a structured training program due to its anti-catabolic effects:

1.  Leucine may help increase lean muscle, strength and decrease body fat following a resistance training program.

2. Help decrease muscle soreness following intense exercise.

3. Help prevent declines in testosterone levels following intense training periods.

4. Help stimulate protein synthesis and slow down protein breakdown.


It was originally assumed that leucine was the key player in the afore-mentioned processes until the notion of HMB being involved came about in the late 90's.  When HMB is combined with a training program it appears to help aid with recovery.  Specifically it may help slow down muscle breakdown during/following intense exercise (i.e. heavy resistance training or 2-a-days).  Therefore if someone is beginning a new training program or upping the intensity, adding HMB to your daily supplement stack may help improve gains in muscle mass, strength and power over time.  It could also help an individual who is trying to cut weight, specifically fat, during a cutting phase by helping maintain lean muscle tissue even though their is a negative energy balance.  Your body does produce leucine each day however only about 5% of leucine is converted into HMB daily....so,


 "To put this into perspective, an individual would need to consume over 600 g of high quality protein to obtain the amount of leucine (60 grams) necessary to produce the typical 3 g daily dosage of HMB that is commonly used" 

                          -ISSN Position Stand on HMB




The following conclusions were released by the International Society of Sports Nutrition in a recent position stand:

1. HMB can be used to enhance recovery by attenuating exercise induced

skeletal muscle damage in trained and untrained populations. 

2. If consuming HMB, an athlete will benefit from

consuming the supplement in close proximity to their workout. 

3. HMB appears to be most effective when

consumed for 2 weeks prior to an exercise bout. 

4. Thirty-eight mg/kg of Body Mass daily of HMB (or about 3-4 g for a 200 lb individual) has been demonstrated to enhance skeletal muscle hypertrophy, strength, and power in untrained and trained populations when the
appropriate exercise prescription is utilized.

5. HMB has been demonstrated to increase Lean Body Mass and functionality in elderly and sedentary populations. 

6. HMB ingestion in conjunction with a structured exercise program may result in greater

declines in fat mass (FM). 

7. HMB's mechanisms of action include an inhibition and increase of proteolysis and

protein synthesis, respectively. 

8. Chronic consumption of HMB is safe in both young and old populations.
