what is ultimate sandbag™?

The Evolution of Functional Fitness!

Developed in 2005 by Strength Coach, Josh Henkin, and Physical Therapist, Jessica Bento, the Ultimate Sandbag™ is the perfect tool to help you improve your fitness in and out of the gym. Josh and Jessica worked on developing a tool that would represent the imperfect nature of the real world and sport. Having been competitive athletes suffering serious back and shoulder injuries, it was important to Josh and Jessica to figure out a system of training that would allow people to build resiliency in their bodies and discover levels of their fitness they never knew possible!

"I was first introduced to the DVRT system at KohPT Lab in 2008 when I was having to rehab from an ACL surgery-  I saw the benefits immediately!  Because it’s not your traditional method of loading, it allows you to explore ranges of motion and movements while under load; strengthening and providing feedback- discovering dysfunctions not seen unless loaded.   As someone who is constantly seeking to provide his clients with the best methods to reach their goals safely and...

With 25 years experience working with clients and competitive athletes, I am well-versed in using many different training tools and modalities.The sandbags have a 'perpetual progressive" component to them that is difficult to encapsulate. Each time you perform a drill with even the same size bag the body...

"In my many years of teaching, training, DVRT Ultimate Sandbag Training has increased my awareness of movement with any modality I now use.The foundational strength I have gained by implementing DVRT and using the Ultimate Sandbag has helped me strengthen weakness I had built from years of lifting, to the mirror.
