In this video, Dr. Jaquish demonstrates a deadlift exercise using the X3 system variable resistance system. As you will see, X3 produces an incredible amount of force without sacrificing safety.
With weights, muscles are underloaded, and joints are overloaded. It’s quite the opposite with the X3 Bar.
The X3 deadlift process allows a user to effectively exercise with more force than would otherwise be possible, even while using a smaller load during the more disadvantaged range of motion to reduce injury risk.
Completing high-intensity variable resistance exercises like X3 has been shown to trigger a greater amount of muscular strength increase than is seen with weight lifting. This is because the exercise load dynamically changes as the user proceeds through each repetition, thereby providing a greater stimulus for muscle growth.
Also, when performing a heavy band deadlift with X3, the heavy duty resistance band bar moves freely, and the lifter must stabilize their body during the process, triggering the release of human growth hormone.

Dr. John Jaquish: When performing the research with my first invention, OsteoStrong, we could see that humans were 7X more powerful in impact-ready positions than they were in the weaker positions.
Dr. John Jaquish: This was data that only I had, and when looking at it, I realized weightlifting is a lousy stimulus for muscle growth. We needed something better. We needed something that had the weight change as we move through different ranges of motion to create greater fatigue of the muscle. Let me show you what I’m talking about.
Dr.John Jaquish: As you can see, lighter forces are used at the bottom of the deadlift movement. This is where people injure, so it is beneficial to have a lower weight here. As we move through the range of motion, the weight climbs all the way up past 600 pounds. So this gives us the benefit of incredible loading—loading that would be higher than what you would see in a standard fitness environment, all so that multiple repetitions can be done and we trigger more growth.
Dr. John Jaquish: When building strength and muscle, there is no getting away from “heavy.” X3 allows you to safely place far heavier loads on the body, which then stimulates hormonal responses that are greater than weight training to induce more growth.
Dr. John Jaquish: You end up with a full-body workout that you can do at home that will be even better than what you get at the gym.
