People are constantly encouraged to lift weights, but often the methods and equipment they use fail to change their physique and even cause injury. What is at the root of inefficient weight lifting that plagues so many workouts? How can you get your central nervous system to help you build muscle? What is the X3 Bar, and why it is the secret to growing muscle and reducing joint pain? On this episode, I’m joined by author, entrepreneur and founder of the X3 Bar, Dr. John Jaquish, who shares how his invention is making a real impact in helping people grow stronger.
Being strong and lean are the two biggest determinants of long life. -Dr. John Jaquish
Three Takeaways
You don’t just go to the gym to lift weights. You go to contract muscle fibers to build up your muscles and bone density.
A lot of the soreness people experience after lifting isn’t caused by lactic acid. It’s just joint damage, which doesn’t do anything for your muscles.
Think of the central nervous system as an engineering team of deaf and blind entities in your body that can only communicate based on the environment you create in the body.
When you do fasted cardio, you reduce growth hormone and increase cortisol. When you lift, you increase growth hormone, which is important in improving your skeletal health.
At the start of the show, John shared what led to the creation of The X3 Bar, and why triggering adaptation in older people is so powerful. Next, we talked about the lessons John learned from gymnasts and why people are more powerful in the impact-ready range of motion. We discussed how to communicate with the central nervous system, and how the X3 Bar triggers androgen receptor sensitivity.
We also discussed:
The dangers of high pain tolerance
The connection between The X3 Bar, testosterone and androgen receptors
The growth hormone effect of the X3 Bar
Going to the gym shouldn’t just be about how much we lift, but about contracting our muscles so that they grow. If our weightlifting is overloading our joints and underloading our muscle, there’s so much potential we’re leaving on the table. How we lift weights needs to help our central nervous system increase growth hormone. To do that you need to train at the right intensity in impact-ready positions. The body is incredibly efficient if we know exactly how to train it.
