A little while back I posted the following video on my Facebook because it got me pretty fired up and I wanted to stimulate some discussion.

.

.

Literally within the first minute fitness guru Paul Chek states that “cardiovascular exercise is one of the most dangerous things you can do”.  He then goes on to suggest that the cortisol response from cardio is going to be detrimental to your health while lifting heavy weights repeatedly is somehow not going to have a similar response (hint: cortisol also rises after resistance training).  He later concludes that your body will adjust to cardiovascular exercise and that the number of calories you can burn will ultimately go down over time and prevent you from being able to lose fat.

.

Of course, I find this interesting because I know a few endurance cyclists (and have seen data from cyclists in various labs) and it appears to me that these people are able to generate HUGE wattages on their bikes and burn through far more calories in an hour of cycling than and a novice rider.  Interestingly, I am betting these people are possibly healthier than the novice riders too, but I’m just speculating here.

.

Then…to make matters worse, Dr. Mecola goes on to post this article that appeared on Facebook with the title “New Study Shows Cardio Workout May Damage Your Heart”.  The title on the actual page is “One of the Worst Forms of Exercise There is”.  Of course, they’re actually talking about this study which ultimately shows that there are some minor right ventricular changes in athletes who have completed endurance races between 3 and 11 hours.

.

Are these really dangerous?  Maybe.  But the reality is that Mercola and his gang are using these changes (and all the stuff from other studies they citied) as surrogate markers for risk of death or cardiac issues which isn’t really a well established relationship.  In fact, part of the conclusion states (with reference to the right ventricular changes) “that the long-term clinical significance of which warrants further study.”

.

Further to that, these are people who ran for 3-11 hours straight!  I couldn’t run for 11 hours if I was being chased by Freddy Krueger.  And if I did, you could probably bet that my heart wouldn’t like it.  As with most things in physiology, there is usually some kind of inverted U pattern for improvement.  No stimulus or a very low stimulus provides very little rests.  A mid-range (optimal) stimulus provides better results.  And going too far and really pushing the envelope can result in some sort of decrease in results.  In this case, the type of training for the races might be optimal for performance, but not health.  Truth be told, I’m not sure the results really even tell us that.

.

.

What I do know is that I’ve never seen cardiovascular exercise listed as one of the major risk factors for cardiovascular death.  In fact, a new paper detailing the leading LIFETIME risk factors for cardiovascular disease listed hypertension (high blood pressure), diabetes, hypercholesterolemia (high cholesterol), and smoking as the 4 most major risk factors.  Nowhere on that list did I see “doing cardio will kill you” or “cardio will esplode your adrenalzzz”.

.

Going a little further down the rabbit hole, there has been plenty of research showing that exercise (including steady state cardio via activities as easy as walking) can improve health.  Heck, you could even do it on a treadmill…in running shoes!  (Yes…I know…blasphemy).  If you have the time I’d suggest you watch Dr. Robert Ross talk about it HERE.  He’s a great speaker with a ton of knowledge and I’d highly suggest you bookmark it if you don’t have time to watch it right now.

.

Does this mean I think steady state exercise is incredible for weight/fat loss?  Not necessarily, but there is some evidence to suggest that cardio alone can contribute to weight loss with around 200 minutes per week making a pretty meaningful difference in some studies.  But if you’re familiar with my blog you’ll know (via the link in the previous sentence) that when combined with diet I don’t think what type of exercise you choose (steady state, metabolic workouts, intervals) really makes a difference in terms of fat loss anyway.

.

I am not personally a fan of long term steady state activity, as I prefer higher paced superset type workouts in the interest of time and preserving muscle mass during fat loss (with the calorie deficit coming mostly from diet).  However, if you know someone who wants to hop on a treadmill for their 30 minutes of steady state cardio they probably aren’t going to die.  In fact, it might just improve their health.

.

Don’t let any internet fearmonger tell you otherwise!

.

PS: If you’ve found this useful or are just plain old fed up with people making up stories about the dangers of cardio, please share this post.

PPS: Using studies that only support your pet theories without examining the entire body of scientific evidence (as was done with the article on the dangers of cardio) is called “cherry picking”.  If you’d like to learn more about how to properly read fitness research you can check out my product HERE.

As I alluded to in my post yesterday, the past couple of years have resulted in huge perspective shifts for me.  Well…far be it for me to stop the trend of change.  As of mid-December I gave up my position in bariatric medicine and decided to take a big step and move my personal training practice to Toronto.

.

I am now part of the personal training team at Medcan which is Canada’s leading preventive healthcare clinic, with over 60 physicians, 240 staff and a 50,000 square foot, state-of-the-art facility, located in the heart of Toronto’s financial district.  They offer a comprehensive health assessment, genetic testing, links with Johns Hopkins Medicine, and a whole host of other incredible services.  The personal training area is complete with turfed areas for drills, sleds for pushing, battle ropes, treatment tables, and even a Bod Pod for body composition testing.  In short, this clinic is AWESOME and I’m ready to kick it into 2012 working with one of the best teams in the country.

.

Of course, this means for me that I’ll be commuting on the train or bus back and forth for up to a few hours every day so I’ll have plenty of time to read, write content for the blog, and finally pull together one or two of the projects that have been on my mind for a while.  So if you’re in Toronto and you’re in need of training please contact me at admin@markyoungtrainingsystems.com for pricing and availability.

Alternatively, if you’re a fitness professional and you’re interested in buying me lunch chatting over coffee shoot me a note and perhaps we can connect.

Just over two years ago I thought I had it all figured out.  I had a degree in kinesiology, I’d been in the fitness industry for over a decade, trained clients for tens of thousands of hours, and had co-owned a training facility with my incredible wife, and I was up on almost every single fitness and nutrition happening on the planet.  I felt at that time I was ready to finally break out and publish my first articles in major online publications as well as starting to blog on a larger scale (rather than just for my clients).  So I did and this blog was the result of that decision.  I published a few articles, connected with some big names in the industry, starting writing posts, and had a rapidly growing readership.

.

Then something happened.

.

My wife and I decided to close our training facility so that we could focus a lot less on running a business and more on having a family.  I took a half time position with a Bariatric Medical Program to help treat people with obesity and continued to train some of my personal training clients out of a friend’s facility (as well as maintaining a small group of online training clients).

.

I Lost My Voice

.

The whole process of becoming a dad, learning more about obesity, getting more in touch with the research I’d been neglecting, and working with clients whose lives had been markedly impacted by their weight created a major perspective shift for me.  I kept trying to write the “same old stuff”, but it became harder and harder to talk about counting calories, carb cycling, and the detailed intricacies of physiology that improve body composition when I was coming to realize more and more that few of these things really matter for the vast majority of the population.  I love them.  They are important.  But not as important as some people would have us believe.  They are the details…and for a lot of people…the details won’t matter a lot until they take care of the bigger issues preventing them from succeeding.

.

But when I started to talk about “less sexy” concepts like behavior change, obesity, general health, and slow (rather than idiotically fast resulting in regain) weight loss my readership dropped.  And further to that, I felt like my joking and fun loving personality didn’t really come through in these posts as I was trying to force content on an industry that wasn’t really interested in what I was saying…or at least I thought they weren’t.  In the blog writing world we talk about the way we write as our “voice” and I felt like I had lost mine.

.

Getting My Voice Back

.

As a result of the perspective change I’d had and the difficulty writing content people wanted to read I slowly decreased my writing to the point where I wasn’t really putting out much at all.  I felt like it wasn’t really reaching people and it certainly wasn’t fun anymore either.  But over the last several months I’ve been thinking a lot about the impact I want to have on this world and this industry and my vision for what I’d like to become is slowly forming.  I feel a passion burning and I KNOW that whether the industry is ready for it or not, it is on me to create a change in whatever way I can for whoever might be listening.  I’ve got my voice back, I know what I’m going to say, and I am going to bring it in 2012.

.

I want to thank all of my readers for supporting me (and also making me laugh on Facebook and Twitter in the meantime).  In the coming year I hope to provide you with a steady stream of content to make you think, challenge you, and help you.  I appreciate whatever help you can give me by sharing my stuff along the way so I can reach as many people as possible.

.

Let’s get after it!
