Kinstretch for Jiu-Jitsu: Upper Extremities

What if your Jiu-Jitsu practice built your body up, instead of breaking it down?

Introducing the most powerful, scientifically proven system you can use to make your body feel better, move better, and become more resilient each week you practice Jiu-Jitsu.


"It's hard to stay healthy in Jiu-Jitsu."

You hear this everywhere you go. And injuries have been accepted as a fact of Jiu-Jitsu life. But it doesn't have to be that way. In fact, it's baffling how simple it is (thanks to the latest sports science) to keep your joints healthy and actually to make them stronger each week, in ever-expanding ranges of motion.

Because you'd think, "hey, if it's this simple, why isn't everyone doing it?" Well, it's sort of like proper breathing, or eating healthy and staying lean, or anything in life really. The difference between wild success and mediocrity or worse is really just a matter of whether you do the work consistently or not. 

And in this case, the work is called "Kinstretch". Kinstretch is a scientifically developed movement system that trains your joints to become stronger and stronger, and more and more mobile each week. The mechanism that makes this all work is based on Functional Range Conditioning (FRC) which is a very well-established methodology for improving mobility and strength of joints. 

What that means in plain English is: as you practice Kinstretch for Jiu-Jitsu, you will be bulletproofing your joints against the most common strains and injuries in Jiu-Jitsu, and at the same time increasing your athletic capacity to be able to move more efficiently and feel better while you do it.  And while there are many places you can learn Kinstretch, Dr. Mike Piekarski is not only a board-certified physical therapist but was also one of the first individuals awarded a black belt by Henry Akins. 

Which makes Dr. Mike Piekarski the most qualified, trusted voice on how to successfully apply Kinstretch to Jiu-Jitsu training and for MMA fighters.
