I bought the CVB to help 16 y/o son with backside incorporation. I should have known from the plethora of "testimonials"  with endless scrolling on order page that it was a scam. Doesn't come with any instructions or DVD. The sheet of paper in the box advises not to use the belt until you visit the website.  When I visited the website, it was down (under construction). Immediately upon purchase they emailed advising for a "limited time" I can get a week's worth of detailed video instruction "for free."    Emailed the guy for this limited "bonus" and he replied he no longer works in that capacity for the company!! Waste of time and money!!

He's also "baseball think tank" if memory serves me.

He's out of Nashville. I've heard good things about him and know folks that have done business with him.

Good luck!

Unless they're anchored at both ends and twisted into knots (like those wooden propeller planes you flew as a kid) rubber bands stretch and pull linearly. A better device for promoting and strengthening hip rotation is a SOMAX machine. The tension is provided by a torsion spring.  I sold the CVB to my neighbor. He uses it to help teach his gymnast daughter how to do back flips.

The resistance on the Somax derives from a torsion spring and, although varying in intensity, remains perpendicular to a given radius. If you look at the angle of the rubber bands of the CVB, they close as the hip turns away and open as the hip turns toward the anchor point. That happens because a rubber band can only apply a linear force. It is an approximation of rotational resistance, and is not how the spine and hips store and release energy. That is why the CVB pulls pitchers down the mound when it is used "improperly."

Updating an old thread with our experience. We purchased the CVB within the last month. My 2018 son and I both highly recommend it. We are also working with Lantz so obviously have more direction in terms of how to use effectively in regards to my son's issues. Lantz has a lot of helpful videos on his youtube page that can help those who are not working with him directly. My son has seen some dramatic improvement in just 2 weeks. Not sure that it is the norm to have big improvements in just 2 weeks but do know that the CVB was a key component. Just our experience and opinions.
