How Short High Intensity Workouts Prevent Diabetes

Diabetes is a serious health concern in all Westernized countries, and it is a major cause of blindness, kidney failure, heart attacks, stroke and lower limb amputation. Exercise has been proven to help prevent the onset of diabetes, however, recommendations to increase exercise tend to fall on deaf ears as most people in developed countries cite lack of time as the reason why they don’t exercise. Short, high intensity workouts appear to have a significant effect in reducing the onset of diabetes and may be one of the best tools in your arsenal, along with proper diet to help reduce your risk of developing this disease. Diabetes is unfortunately considered one of the ubiquitous aspects of getting older as almost 10% of American adults today are living with diabetes, and what is more disturbing is that some estimates show that as many as 79 million Americans are prediabetic. A condition defined as having blood glucose levels that are above normal but below the clinically defined threshold of diabetes. Prediabetes is considered an at-risk state, with high chances of developing diabetes. That’s a little less than a quarter of the entire US population. [1,2] Long term, large scale studies have shown that being prediabetic can cause long term damage to the heart and circulatory system and increase your risk of dying from cardiovascular disease even though there isn’t a full diagnosis of diabetes.[6, 7] There are often no physical symptoms to being prediabetic and everyone should be tested on a regular basis, even children as the incidence of childhood diabetes is sadly rising as well. In this article we will look at how short high intensity training protocols can help reduce the incidence of prediabetes and help more people decrease their risk with time commitments of no more than ten to fifteen minutes three times a week. Do be sure to forward this article to anyone you think might find it to be of use.


Understanding Type II Diabetes

diabetes overview
Main types of diabetes mellitus. Either the pancreas not producing enough insulin or the cells of the body not responding properly to the insulin produced

Type II diabetes is characterized by the inability to produce insulin and often begins with a prediabetic state whereas fat, liver and muscle cells become less sensitive to the effects of insulin. This decrease in sensitivity is called insulin resistance and what is most troubling, is that it is completely avoidable. Under normal circumstances, when you eat a meal, blood glucose levels increase. Glucose is a necessary fuel for everything from brain to muscle activity and your pancreas will secrete the hormone insulin, which directs fat, muscle and liver cells to pull glucose out of the bloodstream. This glucose is then either burned of as fuel or stored for later use as glycogen or as fat. Problems occur when these cells stop responding as they should to direct glucose out of the blood stream leading to prolonged elevated blood sugar levels. As a result, blood glucose remains high and will keep rising if you continue to eat more. The continued high blood glucose levels make your pancreas secrete more insulin as it tries to reduce it. If this continues for too long, insulin resistance in uptake cells increase and the cells of your pancreas cease making insulin as the constant secretion kills them over time. With your pancreas unable to make insulin, blood sugar levels stay high and our bodies are not designed to have high levels of sugar in our blood. High blood sugar leads to kidney failure, heart disease, brain damage, loss of sensation in the hands and feet and other terrible complications and diabetics need injected insulin to regulate their blood sugar.


Why Current Exercise Recommendations for Diabetes Prevention Are Unrealistic 

high intensity training is a better solution for preventing diabetes
As much as we might like to, few people in today’s world have the time to exercise for 5 hours a week.

As horrible as diabetes might be, in the early stages of insulin resistance (prediabetes), studies show that you can stop and even reverse the damage done through proper diet and exercise.  Our ‘Western Style Diet’ has been implicated as the central cause of our increased rates of diabetes[3] in addition to sedentary lifestyles and obesity. Modern marketing makes it difficult for most people to know what foods they need to avoid and so even those who do their best to “eat healthy” can still be prediabetic. Eating a diet of unprocessed or minimally processed foods is an important part of the fight against diabetes, (and will be covered in future articles) but equally important is the need to integrate a regular routine of vigorous exercise and physical activity. The problem is that given the demands of modern living most adults today report not having enough time as being the primary reason why they don’t engage in regular exercise.[4] The U.S. Department of Health recommendations call for at least 150 minutes of moderate intensity aerobic activity, 75 minutes of vigorous aerobic activity or a combination of both spread throughout your week. In addition, they recommend moderate to high intensity muscle strengthening activity, such as weight training at least twice a week, with more benefits from being active at least 5 hours a week.[23]


Most people simply cannot realistically commit to that much exercise on an ongoing basis and one of the interesting aspects of exercise is that researchers are only now understanding the minimum dose requirements. For example, we know that an hour of exercise yields certain benefits, but are those benefits coming from the full hour of working out, or is it that after 10-15 minutes of exercise you receive all the benefits with no additional advantages to training longer? What we know now is that infrequent bouts of brief high intensity training, lasting only 10-15 minutes in duration have been shown to have a positive effect in improving insulin action and are an invaluable resource for those with limited time to exercise with a predisposition towards diabetes and obesity.[5] Over the past twenty seven years, I have had over a dozen men and women who were prediabetic see a complete reversal of the condition following my system of high intensity weight training for ten minutes, three times a week and with no other form of exercise whatsoever. That’s a total of half hour a week and it stands in stark contrast to the five-hour recommendations, but it has stood the test of time not only for reducing the incidence of developing diabetes, but also for weight loss as well.


High Intensity Training As A Preventative Factor Against Pre-Diabetes

high intensity training prevents diabetes

High intensity training is one of the easiest and most efficient ways to prevent and reduce the risks associated with higher blood fasting levels. A recent study found that extremely short duration, high intensity training significantly improves insulin action in young healthy males.[8] Brief high intensity workouts have also been shown to improve cardiovascular health and aerobic function, but it was previously unknown whether high intensity training could improve insulin action and glycemic control. However, an important study published in BMC Endocrine Disorders shows that brief high intensity workouts may have a pivotal role as a time saving exercise protocol for preventing diabetes. For the study, 16 young men in their early twenties underwent a regime of high intensity workouts lasting for 15 minutes each session for two weeks using stationary bicycles. Aerobic performance assessment, as well as an oral glucose tolerance test to determine insulin response were administered both before and after the training sessions. At the end of the two weeks of high intensity training, researchers observed a significant increase in insulin action, as well as a sizeable increase in aerobic performance. Researchers concluded that “the efficacy of a high intensity exercise protocol, involving only ~250 kcal of work each week, to substantially improve insulin action in young sedentary subjects is remarkable…This novel time-efficient training paradigm can be used as a strategy to reduce metabolic risk factors in young and middle aged sedentary populations who otherwise would not adhere to time consuming traditional aerobic exercise regimes.”[9]


The Importance Of Exercise Intensity & Not Duration For Improving Insulin Sensitivity 

Admittedly it was a limited study, but research conducted at Arizona State University and Texas University not only confirm increases in insulin action as a result of short high intensity resistance training, but highlight two very important points:

  1. Higher intensity multiple set training protocols yielded the greatest treatment effect in improving both fasting glucose and insulin [10]
  2. High volume resistance training is not a requirement for improved insulin sensitivity as a result of exercise as individuals performing high intensity low volume exercise have similar improvements in insulin sensitivity as those engaged in higher volume training programs. [11]


In essence, you don’t need to train for prolonged periods of time to decrease your risk of being prediabetic and we should note that short intense workouts not only improve insulin action but increases muscle mass, endurance, aerobic capacity and decreases body fat better than aerobic exercise and conventional high volume training programs.[12,13,14,15,16,17,18] High intensity training protocols have also been shown to increase bone density, improve cardiovascular health and significantly reduce both the incidence and severity of depression.[19,20,21] Since prediabetes can be sometimes difficult to identify without clinical testing, as everyone with it does not always display symptoms such as fatigue, weight gain, difficulty seeing, slow healing of as well as tingling or loss of sensation in the extremities. As such, given its widespread nature, fasting plasma glucose screening is important for everyone over the age of 30 and might be a good idea for younger men and women as well. Especially those who are at risk due to lifestyle and or a high incidence of family history with diabetes. The good news is that only a few minutes of hard training can help reverse it and researchers hope that the high intensity, low volume approach is promoted more as a practical way to exercise in modern times in conjunction with proper diet and maintaining a healthy body weight.

Not Bad For Training Only Three Days A Week!

Because it's three days a week with soul crunching intensity non stop for the past 33 years.

There's no gimmick to it and it means being uncompromisingly all in for your workouts and with your nutrition.

I don't think there's that much that special about me.

There's nothing enhanced, nothing boosted by testosterone and there weren't any special "supplements" along the way.

Just three days of blistering hard work each week and meticulous attention to what I eat.

Being 90% on point each week means you are 100% off after 10 weeks and I can't emphasize enough how much of a difference unshakeable consistency makes to your overall results.

Most of the natural athletes didn't get where they are by any genetic advantage, they just did what is so very rare- which is stick to their process 100%.

It's not easy as it's not always easy and certainly not always popular, but you owe it to yourself to see just how far you can go if you go all in!

Looking forward to seeing your results and as always, Excelsior!!! #naturallyintense

What I Eat To Stay Lean and Keep Building Muscle All Year Round.

If there every was a "secret" to how I consistently stay in shape (and almost 20 years since my last competition) the answer would be my diet.

Diet is the deciding factor in what your body looks like and your overall performance and I want to stress that while this is a layout of the foods I eat on a daily basis, it's not a blueprint for your YOU should be eating.

What it can be is an example of what it takes to maintain a certain degree of size and muscularity at all times as a natural athlete, and also the underlying principle to how I select my foods.

Which is that I don't eat junk foods or highly processed foods and I only drink water.

(No protein shakes, ever!)

If you can start with that, there's no doubt that you will be on the right track in terms of your nutrition.

So stay away from processed foods, know that I believe in you and as always, Excelsior!!! #naturallyintense

Post workout physique check in.

The contest gets closer and closer as the sun meanders across the sky, as my contest is and always will be, did I do everything I possibly could that day to improve?

Did I train hard enough?

Did I push it enough?

The dietary part isn't an issue.

It hasn't been for many years as I always make sure that my nutrition is on point, and there's no leeway on that front.

I don't feel good when I'm not eating optimally, and I respect myself enough to not settle into a place where not feeling my best is the norm.

And to be honest, it feels really good to put my head down at the end of the day knowing that I gave it my all.

Not that I was the best or was even necessarily successful at everything that I set out to accomplish, but knowing that I gave everything nonetheless.

It's a feeling I want everyone to have.

To sleep soundly knowing that you gave it your all.

That you didn't miss an opportunity to improve on what you are passionate about, because in so doing, you experience an eagerness to do the same the next day.

It's the ultimate contest and I invite everyone to submit their application forms, as it's one of the few competitions where everyone who does the work and shows up, is in the winner's circle.

Keep striving, keep pushing and as always, Excelsior! #naturallyintense

(Thanks @indi.anna.r or taking the shot, as I know your arm was probably shaking after that workout!)

Motivation vs Discipline. What You Really Need To Be Successful!

I am often asked what was my motivation to keep going starting off as a skinny 125lb kid who no one believed could ever be a successful bodybuilder.

The answer is that motivation didn't have that much to do with it.

Motivation may have played a part in getting me started, but it was discipline that got me to where I wanted to be.

Motivation is fleeting and ephemeral, it's not always going to be there and on the days when you don't feel like eating right or training hard, you need a disciplined practice to see you through.

A disciplined practiced based on doing what you need to do to be successful regardless of the circumstances.

That's how I made it through all those tough times when I felt I wasn't getting anywhere, and it's what will help you as well.

So forget motivation, focus on building a disciplined practice, know that I believe in you and as always, Excelsior!!! #naturallyintense

Do You Have Good Genetics for Natural Bodybuilding?

I don't believe it's the question that needs to be asked.

Far too many, myself included, who went on to be successful natural bodybuilders would never have been the men and women you would expect to have the genetics for bodybuilding.

But we put in the work, the years, the dedication and the consistency, and so what matters isn't the question of genetics, but rather do you have the passion, the drive and the discipline to train hard and focus on your diet nonstop for years on end to realize your potential?

That's the real question, and yes, there are men and women who have great genetics for natural bodybuilding, but there are even more who would be amazing onstage but don't know it because they didn't believe enough in themselves to put in the time to see how far they could go.

So I am here to say that I believe you have it in you to do amazing things, so if it's your goal, or even if you just want to improve the way you look, stick with it and don't quit!

Know that I believe in you and as always, Excelsior!!! #naturallyintense

Nope it's not a contest cut- it's just another day on the Path.

There are two ways to get cut, the fast way that requires going to extremes and which is inevitably temporary.

Or the Path-based way. Whereby your lifestyle and sustainable healthy practices get you there and keeps you there.

It takes time. It takes patience but it's an extremely honest endeavor.

If you put in the work and stay consistent with your training and following a processed food free and healthy diet, excellence is just a matter of time.

It takes time but as long as you draw breath, you have the time and you can do this.

So take the Path-based way and as always, Excelsior!!!

And my thanks to my son @reid_443 for snapping the shot, and the approval rating! 😂
