French Scientists Discover 30-Second 
“Red Onion Exercise” Boosts Strength 
by 54% In 8 Weeks Flat
... Say GOODBYE To Strenuous Exercises That Can Destroy 
Precious Joint Cartilage, Stress Your Heart & Lungs And Leave 
You Feeling Exhausted All Day

Dear friend,

Scientists in Paris France recently made a startling discovery. After years of research, they stumbled upon a simple 30 second exercise proven to increase muscle strength and overall health by 54% in 8 weeks... without ever touching a weight or doing any strenuous movements (regardless of age or fitness level)...

They call it... "The Red Onion" and if you do it regularly (from your desk at work or your bedside tonight)... your strength will increase by at least 5% per week. You'll be shocked to notice that activities you once thought were "hard" or even impossible, become fluid, easy and pain-free...

But that’s not even the BEST part…  

17 other research studies from top universities (including Yale and Harvard) independently confirmed this unique exercise builds your bodies' "protective armor"... helping to shield you against the most common age-related health disasters such as… heart disease, osteoporosis, sciatica, disc herniation, joint pain and so much more…

Using "The Red Onion" in your exercise regimen is like leveraging $1 and making it do the work of $5 or $10. 

You get a better return on your “workout investment” in a fraction of the time… 

Tragically, it was buried in 1966 by a self-centered “fitness Goliath” in the industry. They locked it away in their hidden vault. Then quietly threw away the key… praying no one would ever find it.

But now, their deception… and the truth behind this remarkable exercise is being exposed…

The “Red Onion Exercise” Discovered In The Most Unusual Place…

You may be wondering who I am and how I discovered the “Red Onion Exercise”.

My name is Todd Kuslikis (sounds like “Koosh-Lick-Iss). 

Over the past 7 years, I’ve been blessed to own and operate one of the most popular bodyweight-based exercise sites online,

But I’m embarrassed to share this with you… even though I taught personal training at a local fitness school in Michigan for several years and have written for top health sites like, and 

I believed the lies from deep-pocketed health clubs claiming fancy equipment is a MUST to improve strength and health. I'm ashamed that I was also sucked into the television ads that shouted "insanity" style workouts (often too hard or too long to even complete) were ideal for the human body. 

Even many of the text books that I taught from... missed a simple truth that I discovered in such an usual place... 

Several years ago, I joined a Tai Chi class in my home town of Grand Rapids, Michigan. I’ll never forget walking into that dimly lit Masonic temple. I would never have imagined my life would be changed forever.

At the end of the lesson, the 60 year-old Grandmaster, affectionately known as “The Doc” (he was renowned for his healing abilities) took me aside and said, “Put your hands around my forearm.”  

Was he about to whip me across the room with his “chi”? 

Not sure, but I timidly obeyed... 

Then something VERY bizarre happened…

I could feel the inner layers of his forearm muscles get tighter… yet the outer muscles were still soft and relaxed. Then he tightened up the next layer and another layer... like a python slowly squeezing it's prey. In a few moments, his entire forearm felt like fortified steel. My hands were now wrapped around a piece of thick iron. 
I had never experienced anything like it. 

This was my first glimpse at "The Red Onion" and the power of “MVC-based” exercise (I'll explain more in a bit). 

But I was amazed by what I saw...and felt. 
The next week when I visited the class again, I enthusiastically shared my "iron-forearm" story with other students. 
Oddly enough, they were NOT surprised.. and enlightened me with their own tales of "iron transformation"...  

A 64 year old man named Steve described it this way… “My favorite is Doc’s 60 second ‘Sun & Moon’ exercise…You feel so invigorated and you don’t even move. My wife has told me she was shocked when she saw how trim I was within a few short weeks. It’s a shame more people don’t know about this.”...

Well, there’s one irresponsible culprit to blame for the burial of this priceless exercise pearl, but I’ll get to him in a second…

After just a few short weeks of using The Red Onion... and more of the Doc's 30 second "iron body exercises" I was startled by the results. My body felt and looked ripped. I was strengthening muscles I never knew I had... and my body surged with energy - like every muscle cell had been "awakened" from a deep slumber... I felt strong, healthy, and alive (unlike many of the fitness techniques I've done in the past that jarred my body and left me with achy, sore joints)... 

What’s the REAL Secret Behind “The Red Onion Exercise”?

French Scientists call it “Maximal Voluntary Contraction” or MVC for short. I’ll explain in a moment the science behind why it’s so effective, and how to “activate” your own MVC, using just your own body. But first...  

When exercise-goers feel this power-packed "squeeze and release" technique for the first time, they feel... to be honest, jipped.

Jipped by the fitness industry for selling them lies.

You too may have suffered through long hours of endless cardio on an elliptical machine… lifting dangerously heavy weights that leave your body battered… or hopping around the living room like a deranged jack rabbit only to hear your throbbing joints crying back at you later that night at 2am.  

Getting a strong, healthy body can be so simple… WITHOUT the unnecessary destruction of our precious joints or wasting another mind-numbing moment in some over-crowded "health club"... 

Yes, when you try out these "squeeze and release" exercises for yourself, you'll activate your “MVC switch” and over a period of only 8 weeks… you’ll enjoy 54% greater strength throughout your entire body. 

You’ll firm up your buns, tighten your stomach and add more muscle tone to your arms.

Not only that…

You’ll have newfound energy and feel like you were in your 20’s or 30’s. Maybe even outrun your kids or grandkids when playing soccer with them… 

You'll be able to ride your bicycle for miles on that cool summer evening and actually feel GOOD afterward (without a single joint complaining to you)…  

Your body will wake up from the deepest sleep you've had in years - feeling rested, alive... ready to handle anything you have planned... with ease and comfort..

Here are just a few real responses from people using this unique technique…

Christy J. from Missouri
Other exercises were so taxing on my body that even 3 times a week gave me symptoms of overtraining and poor recovery… now I’m actually seeing more definition, faster”.

Laurie S. from Jacksonville 
I’ve always hated to exercise. This is the first thing I’ve ever done where I don’t watch the clock count down til I’m done.”

Beth A. from Kansas 
I didn’t move, yet I still feel like I just worked out. Brilliant!

Why Is Maximal Voluntary Contraction (MVC) So POWERFUL?

Compared to other fitness solutions - such as high intensity interval training (HIIT), aerobics and even weight lifting... MVC has an “unfair advantage”. Here’s what I mean...

Imagine you wanted to plant a full-size hydrangea in your front yard. You first have to dig a large hole, right?

If you used a hand spade… you would need literally hundreds of repetitions to dig the hole. 

But if you used a crane, it would take only one or two scoops… and you’d be done.

Your muscles work the same way. Did you know that you have 840 different muscles in your body

And each muscle is divided into 10-100 muscle fibers inside each muscle. When you exercise, your brain signals ONLY the minimal amount of fibers needed to complete a movement.  

So you have to wait until those muscle fibers "tire out", then your brain tells more fibers to pick up the slack. This happens hundreds of times during a workout until all the fibers are worked.  

But when you use Maximal Voluntary Contraction (MVC), you’re like an Army Sergeant that tells EVERY cadet to go now. Aka... all fibers engage at once. So your body gets stronger and healthier… WAY faster.

3 Key Elements to Activate Your “MVC Switch” & Accelerate Your Strength & Health

MVC is activated by a unique form of isometric-based exercise. You may have heard of traditional isometric exercises already. They are exercises where you tense up the muscle without moving the joint. Maybe you’ve done a “wall sit” in High School or held a “downward dog” in a yoga class.

Yet, this is different...

There are 3 types of isometric exercises needed (static, yielding and overcoming isometrics)...  

And they are combined in a unique sequence to activate MVC and give you the strong, healthy body you’ve dreamed of.

Think of them as the "3 Strength Musketeers". They work in perfect harmony to give you the maximum benefit from every exercise, in less time. 

The best part is that anyone can do them... no matter what your fitness level or age - or even if you've suffered from a recent injury. And you actually feel good after doing them (one student claimed "it's like drinking a cup of espresso without the after-jitters"). 

If you are sick of wasting endless hours at the gym or feel exhausted after traditional “high intensity” exercises…  

If you want to feel stronger and healthier than you did in your early years… so you can enjoy all your favorite activities well into your 70’s, 80’s and beyond…

The “Red Onion Exercise” technique is a “must-have” for every man and woman over the age of 45…

You may be wondering, “Why haven’t I heard of this before?”

Massive Cover Up Behind America’s Most Popular Strength & Health Magazine

A college student working at the renowned “Strength & Health Magazine” way back in the summer of 1966... recently revealed a tragic cover-up that took place over 5 decades ago.

He shared one of the biggest dilemmas while working at the magazine during that time... was that sales for barbells had drastically declined because of the growing popularity of isometrics.

Later he revealed in a public thread they received a huge number of letters from men and women who had achieved better results using isometrics... than they did with weights.

Check this out…

Several men took a “lay off” from weights and used isometrics instead. After a couple of months, when they went back to the weight room, they were even stronger than before they had taken the lay off.

In his “tell all” letter, the intern revealed that they constantly received letters from readers that got injured, but those letters never saw the light of day.

Injuries were extremely common because of the constant admonition in the magazine to lift heavier and heavier weights”.

Several of the men that worked at the magazine also sustained injuries and were forced to take a break from weights.  So they practiced isometrics and did so with fantastic results. 

Here’s how the intern describes what he witnessed while working at the magazine's headquarters in York, Pennsylvania…

They achieved levels of development and muscular definition they had not seen in years… fantastic results in hardening of physique and the men kept going around asking people to ‘feel my muscles’”.

So why weren’t these results publicized?

In the health and fitness industry…

Cash is king.

A new subscriber that purchases an Olympic power rack, barbell and weights could spend at minimum of $1,997. Compare that to teaching you how to turn on your bodies “MVC switch”... so you can increase your strength, from home, without ever touching a weight.

That's why this powerful MVC-strength method was buried by this once-trusted fitness publication...

But science now confirms these amazing results... 
Scientists from Paris France Discover This Simple Exercise Increases Strength By 54%  

In a laboratory in Paris France, three scientists, Thepaut-Mathiew, Van Hoeck and Maton, wanted to learn if strength could increase using a simple protocol of isometric exercises.

After assembling a group of “every day folks” (non-athletes, ages 30-65), they assigned them 30-60 seconds of a few non-movement “squeezes” a few times a week for 5 weeks.

They measured the results and were startled by what they saw....

Participants increased their strength levels anywhere from 23-54%! And they felt better than they had in years with more energy and vitality. 

Does “Maximal Voluntary Contraction” build lean muscle?

That’s what researchers in the Journal of Physiology wanted to learn.

They compared MVC based exercises versus dynamic strength training (traditional exercises you’ve probably tried for years).

Two amazing results were found.

Participants on average increased their overall strength by 45%... AND had a 5% growth in lean muscle mass.

But the benefits of this near forgotten exercise don’t stop there...

17 different studies performed by top universities and publications revealed strength and lean muscle were just the beginning of the benefits

The Red Onion Technique Scientifically-Proven To Lower Cardiovascular Risk, Increase Bone Density
Protect Against Joint Pain

  •  Increase mineral density in bone [24]
  •  Injury recovery and prevention [16]
  •  So many more…

If you are willing to spare three short 30-minute "squeeze sessions' per week to firm up your entire body and increase your strength by 54%... and prevent some of the most common age-related ailments… without even putting on your workout clothes (no "bopping around" like with almost every other fitness method)...

Then I’d like to introduce you to something VERY special and unique…

How Do You Get A Copy of 8 Week Isometrics Strength System for Maximum Strength & Health Improvement? 

Hold on… I’d like to reveal once last but important benefit you’re about to experience...
Did you know that this once-buried exercise technique has even been medically-proven to melt off 22.3 pounds of ugly and unhealthy body fat in 30 days…?

It’s true.

The American Medical Association discovered this in 2003... “The weight loss for some subjects in the first two weeks was as high as 18.5 lbs, after 4 weeks some subjects lost as much as 22.3 lbs in body weight using this technique”...

If you perform the simple “MVC squeezes” for the prescribed time, 3X per week… you'll be pleasantly surprised to see a trimmer waist smiling back at you in the mirror.

Why does it work so well for fat loss? 

Your body burns more calories in the 24 hours after an MVC strength training workout than nearly any other type of workout. In fact, as your strength and lean muscle increase... your body will automatically burn an EXTRA 30-50 calories per day (for every extra pound of new lean muscle)...without changing one thing about your diet.  

That's why I can say MVC exercises are like $1 doing the work of $5 or $10...

Yes! There are numerous studies that show at least a 5% increase in cross-sectional area after performing an isometrics program. Cross-sectional area means the girth or “wideness” of a certain body part. The amount of strength in your muscles have also been proven to increase tremendously, even when compared to concentric and eccentric workout regimens. The Isometrics Strength program will guide you through a 30 minute workout done 3-4 times a week that incorporates the right methods to build strength and size using isometrics.
Yes, as mentioned above, isometrics are extremely powerful to help you melt unwanted fat right off your body. But in addition… you’ll get access to simple and very powerful “diet tweaks” to accelerate your fat loss. 
Honestly, this is up to you. The Isometrics Strength program outlines a schedule of 3-4 times per week. But, if you already have a strength program that you are following than you can use it as an “add on.” The second part of the workout only takes 3-5 minutes to complete. This makes it a great finisher to any workout. 
Absolutely. You may already have a strength training program that you currently perform. Isometrics are a great additional method that will “finish off” your muscle even more than if you were to do your current program alone. In Isometrics Strength, I teach you the 50/40/10 Rule in how to properly add isometrics to your current program. 
Isometrics Strength is a digital download product so you’ll get access to the program right away. No need to wait for shipping and you can access it from your computer, smart phone or tablet.
With your purchase of Isometrics Strength, you get a FREE 14-day trial to our Feel Good Life Academy. In this Elite VIP Academy... you’ll discover the most powerful & scientifically proven “health hacks” to add years to your life… and help you feel amazing. 

For example, did you know there are three herbs that contain anti-cancer effects… or what your fingernails are revealing about your health (and what to do about it). Or the BEST quick trick to cure nighttime leg cramps (also 3 ways to prevent them)?

Research has shown using isometrics based programs can help you add 5% extra strength per week. But realize each person is different and responds differently to the program. Some will gain strength faster… other’s it will take more time. Be patient with yourself. It’s a journey.  
Nope. That’s the great thing about the “MVC-holds” and Isometrics Strength. You don’t need any equipment.
