Body by Science by Doug McGuff and John Little is a short but very intense look at “strength training, body building and complete fitness in 12 minutes a week.” During my first reading, I was overwhelmed by the science (which gets pretty technical) and thought that maybe everything I had ever learned about training and fitness was wrong. Or I had at least misunderstood.or been mislead.But, a second reading changed my mind. The book is intended for those who are very serious about fitness — and the authors’ training ideas are backed up by science and research. I could not ignore what they had to say and keep doing everything in my fitness classes precisely the same as I had always done them. At the same time, most of their suggestions involve using machines (not free weights) and working with one individual at a time, not a group.

It was tough to reconcile the differences and decide what to do.I asked myself how I could adapt their excellent ideas to what I do four times a week in my fitness classes, often with people who are older than 55. I had to skim the book a third time to answer that question. In the end, I found four concepts that I can use in my own life and with my fitness class participants.

I do not include here all the science that is discussed to back up their assertions, merely the conclusions. If you want to know the detailed science and the research, read the book! Health, Fitness and MetabolismAn early statement in the book, after defining health, fitness, and exercise is: “In reality, fitness and health are not extrinsically linked; as one goes up, the other does not necessarily go up with it.”The authors go on to say: “It should be acknowledged that longevity, as with fitness, is not necessarily linked to health. It can be, but the important thing to remember is that health is ultimately linked to DNA — the self-replicating molecule that creates our bodies. The purpose of the body from the DNA”s standpoint is merely to function as a vehicle to carry it forward into the future.”No fitness instructor can promise a fitness participant that if they attend their class, they will lose weight or get healthier. It just doesn’t necessarily go together.In addition, the fitness industry in general has centred our drive for fitness and health on the cardiorespiratory system. But McGuff and Little state that “the center of metabolic health.is not the heart and cardiovascular system; it is the muscular system.It’s in the muscle where all the ‘gold’ that can be panned from exercise is found.

The fitness world’s misplaced focus on the cardiovascular system needs to be redirected to the muscular system, because that’s where everything that results in positive adaptive change happens.”If you are a runner, you will not like this book! (Although they don’t discuss it much, I doubt they have much good to say about step classes either.) A combination of some aerobic intensity (see below) combined with strength training (see below) is the most likely path to metabolic health. Aerobic IntensityResearch shows that aerobic effects need not be long.

How long does that mean? Would you believe as little as seven minutes once a week? “How could so little time spent exercising produce the same aerobic effects as more conventional workouts in only about 2 percent of the time?” the authors ask rhetorically. They reply, quite simply: “high-intensity muscular effort.”Research shows that seven minutes of moderate-to-high intensity aerobic effort once a week is enough to keep the cardiovascular system working well. I’m pleased to say that we accomplish that in my fitness class, as we begin with mobilizations and range-of-motion activities and then move on to slightly higher levels of intensity, ending with about a seven-to-ten minute section of moderate-to-high intensity movement. It’s one of the reasons I call my class Light Fit.

McGuff and Little might very well feel that I have chosen the wrong name. Effective Strength TrainingSo how do McGuff and Little approach strength training and make it effective? “Effective strength training.is an aggressive recruitment and momentary weakening of muscle fibers. If you are able to recruit, fatigue, and weaken muscle fibers within a defined time frame, then you are going to recruit all of the different muscle fiber types aggressively and therefore get the most mechanical and metabolic effect for producing an adaptation. If the exercises are performed properly — that is, in accord with muscle and joint function — you can do so in a way that eliminates all of the other extraneous components, such as excessive force and excessive wear and tear on the joints, which are completely unnecessary for the delivery of the stimulus.”It really doesn’t matter, say the authors, how many reps and sets you do.

What matters is whether or not you push the muscle to fatigue. And you only have to do that once a week with each exercise!“This is one of the unique advantages of strength training,” the authors continue. The forces are low to begin with: If you start with a weight of 100 pounds, it stays at 100 pounds, requiring the same amount of force to move it at the end of the set as it does at the beginning, even as your fiber recruitment and rate of fatigue increase.”As a fitness instructor, I will teach this concept to my participants. If you want strength training to be effective, you need to use the right weight and proper form.

And, most important of all, you don’t quit until you know that your muscle is fatigued. Otherwise, you may well be wasting your time.See also: Rest or Recovery of Muscle Fibers“Two different aspects of recovery need to be distinguished. One is the temporary recovery of the various fibers of the muscle. The other is the recovery of the energy and resources that are expended during a workout.

What we’re referring to in this context is the recovery.involved to the point where they are capable of contracting again.”How long might this be? It partly depends on the fibres which you tap into.

If you are making use of the fibers we use when fleeing from a man-eating lion, these fibers, “once tapped, can take four to ten days (or longer) to fully recover.” If, however, you are aiming for “momentary muscular failure,” then those fibers would be available for recruitment after three days of rest. Your slowest-twitch motor unit, by contrast, would be available for recruitment again after a rest of ninety seconds.”Resting between exercise sessions is vital for muscle growth, development, and maintenance.

Over-training can happen all too easily if we convince ourselves that going to the gym every day is essential. See also Over-training. Final ThoughtsThe research has been there — coming in by dribs and drabs — for quite a while: we don’t have to “do” fitness every day for even an hour. Two clear messages of the book, and well worth considering when planning your own schedule: how and how often do you exercise? And do you rest in between?

A different philosophy: Leverage highly time efficient workouts to increase strength, build lean mass, promote cardiovascular performance and provide longevity benefits.In 2009 I found my time getting swallowed up by the demands of my career job while starting my own business on the side and trying to keep to my crossfit workout program ( which I dearly loved).I barely had any time or energy to socialize or get anything else done. More worryingly my performance in my workouts was going down – not up. I found myself getting more and more tired during and after workouts, having to hold off on some exercises due to persistent muscle soreness and back and shoulder muscle injuries.I finally stopped ignoring that my exercise program wasn’t helping.Something was going to have to give – but I needed exercise for stress relief as well as to stay healthy.

I needed to find time-efficient workouts and how to optimize workouts for strength and size gainsToday’s interview is about how I fixed all of these problems, re-found greater health, higher energy levels and saved a crap load of time so I could work even harder on my startup. And discovered the joys of tracking workout results, and watching them improve every single workout. Enter the Time-Efficient WorkoutThe solution found me in a bookstore. The book’s title popped out at me as the answer to my problems (and seeming far too good to be true). ““.Today’s guest is Doug McGuff, co-author of the book, and an emergency doctor, gym owner and weight lifter.His book describes how to perform, track accurately and optimize High Intensity Training workouts, and the many well researched benefits to doing this type of workout.Doug himself has been practicing high intensity training since age 15 – that’s 37 years, and been training clients with it since 1997 (that’s 17 years!). As you’ll see in the interview Doug has a very solid grip on the research and science behind his workouts.The show notes, biomarkers, and links to the apps, devices and labs and everything else mentioned are below.

Damien Blenkinsopp: Doug, thank you so much for coming on the show today. As I mentioned, I have been using your workout since 2009 and they really change the way I approach everything and really help me in various areas of my life beyond working out. So I think this is a fantastic, interesting topic and of course it has got loads of quantifying areas too, so thank you for coming up.Doug McGuff: Thank you, Damien, It is a pleasure to be here.Damien Blenkinsopp: Just to give people a little bit of background, you published your book, Body By Science, in 2009. Could you give us a brief background of where these workouts and this approach came from and a bit of the history and what led to you publishing that book?Doug McGuff: Sure. It has been a lifelong interest of mine, probably since I was about 14 or 15 years old.

I started working out around that time and I was doing it to improve performance as a BMX racer, which is a type of sprint bicycle racing, and it worked so astoundingly well that I was immediately hooked. And that was back in the late 1970s, and it just so happened at that time the nautilus training concept was exploding. That was invented by Arthur Jones to introduce the idea of high- intensity training, that by making the intensity level of the exercise higher, that the exercise could be more effective and more time-efficient. I traded my janitorial services for a membership at a Nautilus gym and while cleaning up in the office I found a copy of The Nautilus Training Principles Bulletin written by Arthur Jones. And the owner let me take a copy of it and I read it cover to cover in one sitting and have been interested ever since.Over time, that concept of high-intensity training has been refined more and more over the years.

The idea of a high-intensity training is that the intensity and the amount of training are inversely proportional out of necessity. And as more and more refinements were made to produce higher and higher levels of intensity, what was found was that for the body to recover and produce a good adaptive change that ratio, that inverse ratio, was actually quite disproportionate.

For any incremental increase in intensity you are able to achieve through modifications in protocol or equipment, that the amount and frequency in training had to go down disproportionately.Probably the first time that was really driven home was in the 1980s when Nautilus was researching the use of high-intensity strength training for the treatment of osteoporosis. And they created what led into the super slow exercise protocol, lifting and lower the weight very slowly in order to protect these elderly, frail women that they were training.

And what they found was two things – one is very little went a long way. It was very easy to overtrain people. New biology for engineers and computer scientists ebooking. And two, a rate of progress that was much more dramatic than they had seen in the past.

And they thought perhaps that was attributable to the fact that these were elderly and deconditioned subjects, but when they took the protocol and applied it to more normal athletic populations, they found a similar sort of response.
