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!”

See What People Are Saying

  • “The X3 (concept described in this book) is a great addition to our program. It is joint-friendly, and the variable resistance with a diminishing range of motion is a game changer. We have not been able to duplicate it with any other equipment. With the crazy NBA travel, it makes for great workouts on the road as well.”

    Bill Foran, Strength and Conditioning Coach for the Miami HEAT. USA Strength and Conditioning Hall of Fame

  • “I admit I was skeptical of the system in this book. I'm a convert now. I use it like 2x or 3x a week, and only for like 10 minutes in the morning. I've put on at least 4 pounds of muscle and was already in great shape. I even quit my gym. I save a few hours a day and a few thousand dollars a year and get better results.”

    Tucker Max, 4x New York Times bestselling author

  • “With the X3 bar, I tried it for a few weeks before I promoted it. I was like, holy crap, this is different.” “I feel like the X3 is one of the things that turns on that muscle stimulation faster than lifting heavy stuff.””

    Dave Asprey

    Dave Asprey, 4x New York Times bestselling author, ‘Father of Biohacking’

  • “Musculoskeletal health is key for disease prevention, function, and longevity. Resistance training with heavy loads is essential to building and preserving lean muscle mass. The X3 bar, discussed in this book, offers an efficient, safe way to achieve necessary loads with added benefit of variable resistance to boost muscle growth!”

    Ben Greenfield, New York Times bestselling author. Host of one of the world's top fitness podcasts

  • “Dr. Jaquish has fundamentally reshaped my understanding of exercise’s physiological effects, the benefits of variable resistance, and the impact of intermittent fasting. His guidance helped me build a sustainable framework for health and longevity, which I've since shared with colleagues and patients.”
