X3 Bar

Train with Greater Force to Trigger Greater Gains

The Jaquish Biomedical X3 Elite is a complete home gym system that provides greater exercise benefits than free weights, cable machines, and “smart” home gyms.

X3 safely channels the power of variable resistance training through heavy-duty resistance bands, steel ground plate, and machined alloy steel bar.

“The X3 bar is a highly effective, time and equipment efficient way to safely produce the necessary loads with the added benefit of variable resistance to further stimulate aggressive muscle growth!”

Weightlifting is a Waste of Time

Read the WSJ Best-Selling Book that Exposes the Failures of Fitness

In Dr. John Jaquish’s Wall Street Journal best-selling book, Weightlifting Is a Waste of Time, he discusses why weightlifting is a failed human endeavor and how modern exercise science has missed obvious principles.

Once implemented, these principles will help you build more muscle than you thought possible in less time than going to the gym.

“After seven orthopedic surgeries, lifting conventional weights just wasn’t an option for me any longer. Fortunately, I met Dr. Jaquish, whose discoveries have allowed me to maintain size and strength without any damage to my joints.”

X3 Inventor John Jaquish: a Revolutionary Approach to Bone Health & Muscle Growth #134

John Jaquish is a visionary biomedical engineer. His inventions are revolutionizing the way we think about muscle hypertrophy and disrupted the conventional beliefs about muscular strength and bone health. He’s an outside the box thinker whose story demonstrates that unconventional thinking is not enough for success. You gotta have determination and perseverance if you have any hope that your innovations will ever see the light of day. From pursuing his PhD to developing osteogenic loading devices, he has confronted and overcome the skepticism of his colleagues, of academic gatekeepers and even fellow strength and conditioning experts. His research into osteogenic loading led directly to the development of X3, an exercise system that overcomes the limitations inherent in traditional resistance training systems. Whether you agree or disagree with his conclusions, you will definitely be entertained.

Variable Resistance: The Ultimate Muscle Hack – Dr. John Jaquish | 1136 | Dave Asprey

Today we're talking about testosterone replacement and unpacking the novel concepts of progressive overload and variable resistance training—both methods to gain, and keep, muscle mass in your body without living in the gym. I’m joined by strength expert, entrepreneur, past guest of the show, and PhD, John Jaquish. John has spent years researching and developing improved approaches to health. Inventor of X3, a technology that is proven to develop muscle much faster than conventional weight lifting with the lowest risk of joint injury, Dr. Jaquish’s methods are used in training the world's most elite athletes as well as Olympians. Aligning with the most basic tenet of biohacking, if you can achieve all of your physical or athletic goals in half the time of your competitors, why not explore the option? John is as gracious as he is informed in this one, detailing the benefits of variable resistance training and indulging me in a super deep dive into diet and nutrition experimentation, testosterone replacement therapy, and efficient muscle growth. You’ll learn what he eats every day to look as good as he does. You’ll get repetition-count-specific recommendations on ultra-quick workout routines.
