In this video, Dr. Jaquish demonstrates a deadlift exercise using the
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 up to three times the amount of muscular strength increase 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
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

invention, OsteoStrong, we could see that humans were 7X more powerful in
impact-ready positions than they were in the weaker positions. Dr. Jaquish: [0:13–0:37] 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. Jaquish: [0:38–1:12] 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. Jaquish: [1:13–1:29] 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. Jaquish: [1:30–1:41] 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.
