About the WSJ Best Selling Book

Many fitness “experts” defend weights and cardio like they are infallible, but where are the results? Why does almost nobody look even marginally athletic?

Fitness may be the most failed human endeavor, and you are about to see how exercise science has missed some obvious principles that when enacted will turn you into the superhuman you always wanted to be.

In Weight Lifting is a Waste of Time, Dr. John Jaquish and Henry Alkire explore the science that supports this argument and lay out a superior strength training approach that has been seen to put 20 pounds of muscle on drug-free, experienced lifters (i.e. not beginners) in six months.

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.

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.

Dr. Jaquish has fundamentally reshaped my understanding of exercise’s physiological effects, the benefits of variable resistance, and the impact of intermittent fasting.

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!
