Review of Chris Highcock’s Hillfit

 

Chris Highcock over at Conditioning Research has just released a new ebook on strength training for hikers: Hillfit: Strength.  Hiking is one of my favorite hobbies.  I particularly like walking up hills and mountains.  If you’re ready to reap the benefits of resistance training, this jargon-free plan is an excellent starting point, and may be all you’ll ever need.  Even if you never go hiking.

Chris is a fitness columnist for “TGO (The Great Outdoors).”  He lives and hikes in Scotland.  Chris’s goal with the program is to increase your enjoyment of hiking by increasing your level of fitness. 

He clearly presents four basic home exercises requiring no special equipment; they’re bodyweight exercises.  You get it done in 15 minutes twice a week!  The key is to do one set of each exercise, slowly, to exhaustion.  What’s slow?  Ten seconds for both lift and lowering.  For instance, when you do the push-up, you push up over  the course of 10 seconds, then let your body down slowly over 10 seconds.  The exercises are for both upper and lower body.

I’m reading about similar exercise ideas from Skyler Tanner, Doug McGuff, Nassim Taleb, Jonathan Bailor, and Doug Robb.  Bailor, in his recent book, also recommends only four exercises.  Highcock’s look a little safer for rank beginners. 

The idea is to recruit three different types of muscle fiber during the muscle’s movement.  If you move explosively and finish too soon (get your mind out of the gutter!), you’re only using  one type of muscle fiber (fast twitch, I think).  You want to stimulate a strength and growth response in all three types of muscle fiber.  And explosive or rapid movements are more likely to cause injury, without any benefit. 

Once you get the basic program down, Chris takes you through some easy variations (called progressions) to make the exercises gradually harder, so you continue to improve your strength and fitness. 

Chris understands that many folks can’t do a single push-up.  He takes you through pre-push-up movements to get you prepared  to do actual push-ups.  This goes for all four exercises.  I bet even my little old lady patients could use this program.  (This is not blanket clearance for everybody to use this program; I don’t need the lawsuits.  Get clearance from your own doctor first.)

The exercises incorporate our five basic movements: push, pull, squat, bend/hinge, walk/gait.  The four exercises are: wall sit (squat), push-up, modified row, and hip extension.

My only criticism of the book is that Chris should have used young, attractive, bikini-clad models to illustrate the exercises.  (That’s right, my wife doesn’t read this blog.)  The existing photos are clear and helpful, however.

But seriously, the only suggestion I have for the next version of Hillfit would be to mention that it will take a couple or three weeks to see much, if any, improvement in strength once you start the program.  Same for when you increase the workload with the exercise progressions.  Perhaps this is in there, but I missed it.  You don’t want people quitting in frustration that they’re not seeing progress soon enough.

The author provides scientific references in support of his program, so he didn’t just make this stuff up.  Only one of the references involved mice!

Several “take home” points for me personally are: 1) stretching before or after exercise does nothing to prevent injury or soreness, and may hurt short-term athletic performance, 2) don’t hold your breath, 3) train to “momentary muscular failure.”  I’m not entirely sure what momentary muscular failure means.  It may not be Chris’s term, but it’s prominent in one of his best scientific references.  I use free weights and don’t think I can safely go 100% to momentary muscular failure.  Hitting momentary muscular failure, by the way, is more important than the amount of weight you’re moving.

Highly recommended.

PS: I’d like to see Hillfit available on Amazon’s Kindle and Barnes and Noble’s Nook.

PPS: When you go to the Hillfit website to order, you’ll find the price is £9.95 (that’s GBP, British pounds sterling).  I’ve never ordered anything priced in GBP.  In today’s U.S. dollars, that’s a little under $16.00.  You can pay via PayPal or a major credit card.  I assume the conversion from one currency to another is automatic and seamless.  I don’t know if there’s a extra fee by the payment processor for doing the conversion.

Disclosure:  Chris kindly sent me a free digital copy of his ebook.  I don’t know Chris.  I will receive no remuneration for this review, nor for book sales.

Is Your Strength Training Regimen Outdated?

Not Chris Highcock

I’m reading Hillfit: Stength, an ebook  by Chris Highcock of Conditioning Research.  One of the scientific review articles he cites in support of his recommendations is an eye-opener.

Evidence-Based Resistance Training Recommendations is available free online.  It’s published in Medicina Sportiva, which I’m not familiar with.  I’ll confess I’ve read little of the hard-core literature on the science of strength training.  It’s one of my more recent interests.

An excerpt:

We recommend that appreciably the same muscular strength and endurance adaptations can be attained by performing a single set of ~8-12 repetitions to momentary muscular failure, at a repetition duration that maintains muscular tension throughout the entire range of motion, for most major muscle groups once or twice each week. All resistance types (e.g. free-weights, resistance machines, bodyweight, etc.) show potential for increases in strength, with no significant difference between them, although resistance machines appear to pose a lower risk of injury.

The article has already got me questioning some of my notions, such as how often to work out, number of reps moving a weight, speed of moving a weight, and whether I should stick with free weights.  Why not see if your dogma is supported?  Worth a look.

How Has the U.S. Diet Changed Over the Last Century?

U.S. obesity rate over last 40 years

Beth Mazur over at Weight Maven has posted a lecture by Dr. Stephan Guyenet in which he outlines the changes in American diet over the last 100 years.  It’s only 16 minutes long.  You may  find an explanation for our excess weight problem and some other “diseases of civilization.”

Is the “Calories In/Calories” Theory Outdated?

Not watching The Biggest Loser

Dr. Barry Sears (Ph.D., I think) recently wrote about a lecture he attended by a dietitian affiliated with “The Biggest Loser” TV show.  She revealed the keys to weight-loss success, at least on that show.  Calorie restriction is a major feature, with the typical 300-pounder (136 kg) eating 1,750 calories a day. 

On my Advanced Mediterranean Diet, 300-pounders get 2,300 calories (men) or 1,900 calories (women). 

Although not stressed by Dr. Sears, my impression is that contestants exercise a huge amount. 

Go to the Sears  link above and you’ll learn that all contestants are paid to participate.  In researching my Conquer Diabetes and Prediabetes book, I learned that the actual Biggest Loser wins $250,000 (USD).  Also, “The Biggest Loser” is an international phenomenon with multiple countries hosting their own versions, with different pay-off amounts.  A former winner, Ali Vincent, lives in my part of the world and still has some celebrity status.

This TV show demonstrates that the calories in/calories out theory of body weight still applies, including the fact that massive exercise can help significantly with weight loss.  In real-world situations, exercise contributes only a small degree to loss of excess weight. 

The major take-home point of the show, for me, is that you can indeed make food and physical activity choices that determine your weight.

Most of us watch too much

I know losing 50 to 10o pounds of fat (25–45 kg) and keeping it off for a couple years is hard; most folks can’t do it.  Do you think you’d be more successful if I gave you $250,ooo for your success?

Modern Paleo Movement History

Keith Thomas of EvFit has an ongoing “annotated chronology of books, films, websites, research etc. relating human diet and lifestyle to human evolution.”  In other words, a timeline for the modern paleo movement.

Chris Highcock of Conditioning Research did an interview with Keith Thomas (“A Paleo Pioneer”) in 2010.

Chris Highcock’s Interview With Ray Audette

In a recent comment here, Chris Highcock of Conditioning Research mentioned his 2010 interview with Ray Audette.  Audette is the author of 1999s Neanderthin, one of the first popular press books about the Paleolithic diet and lifestyle.  I bring it up here only because I don’t want it lost in the comment section.  Read the brief interview to find Audette’s Bible quote and connection to the Dixie Chicks.  I spent many years in Texas and therefore feel a strange connection to Audette.  And we both like bluegrass music.

Who’s Ray Audette?

Ray Audette hunted with hawks

I ran across a 1995 well-researched online article about Ray Audette, author of NeanderThin and one of the modern paleo movement pioneers.  It’s in Dallas Observer News: http://www.dallasobserver.com/1995-07-06/news/neander-guy/

Audette apparently self-published his book in 1995.  (Publishing by a “vanity press” is probably more accurate for the mid-90s.)  The 2000 edition of the book from St. Martin’s Paperbacks has a foreword by Dr. Michael Eades, who is also quoted liberally in the aforementioned article.

Mr. Audette credited his diet for curing both his diabetes and rheumatoid arthritis.  I wonder how he’s doing these days.

1995 was only17 years ago.  It seems like ancient history to me.

Dr. Andreas Eenfeldt Explains the LCHF Diet

LCHF Cheese

Dr. Eenfeldt of DietDoctor.com gave a talk at the inaugural Ancestral Health Symposium in California, on the rationale of the current low-carb, high-fat diet (LCHF) so popular in his home country of Sweden.  It’s very understandable to the general public and is a good introduction to low-carb eating.  The entire YouTube video is 55 minutes; if you’re pressed for time, skip the 10-minute Q&A at the end.

He also discusses the benefits of LCHF eating for his patients with diabetes.

If you reduce carbohydrate, you’re going to replace it with either protein, fat, or both.  Carbohydrate restriction, whether or not part of a Paleolithic eating pattern, generally improves blood sugar levels, especially in people with diabetes.
