Click a second time, and the message goes away. Or I had at least misunderstood But, a second reading changed my mind. 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 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! An early statement in the book, after defining health, fitness, and exercise is: The authors go on to say: 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.


No fitness instructor can promise a fitness participant that if they attend their class, they will lose weight or get healthier.

In addition, the fitness industry in general has centred our drive for fitness and health on the cardiorespiratory system. If you are a runner, you will not like this book! A combination of some aerobic intensity see below combined with strength training see below is the most likely path to metabolic health. Research mcyuff that aerobic effects need not be long.

How long does that mean?

Body By Science High Intensity Training Review: My 9 Month Experiment

Would you believe as little as seven minutes once a week? They reply, quite simply: Research shows that seven minutes of moderate-to-high intensity aerobic effort once a week is enough to keep the cardiovascular system working well.

McGuff and Little might very well feel that I have chosen the wrong name. So how do McGuff and Little approach strength training and make it effective? 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 mchuff muscle and joint function mcgufr 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. What matters is whether or not you push the scisnce to fatigue. And you only have to do that once a week with each exercise!

The forces are low to begin with: If you start with a weight of pounds, it stays at 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. Otherwise, you may well be wasting your time. 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. How long might this be? It partly depends on the fibres which you tap into. 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. The research has been there — coming in by dribs and drabs — for quite a while: Two clear messages of the book, and well worth considering when planning your own schedule: And do you rest in between? You can be fit without sacrificing hours and hours of your time every single day.
