Our Story: The Creation of the DVRT Ultimate Sandbag Training Revolution!

Not Fitness Equipment, The Ultimate Solution

Let’s face it, you aren’t here for a fitness sandbag. You don’t need more equipment, you demand better solutions. The Ultimate Sandbag was designed to be just that! The most efficient, effective, challenging, and fun way to unlock your potential for better movement, fitness, and well-being.

How do we know? Because Ultimate Sandbag Training wasn’t designed in some corporate board room. No! The Ultimate Sandbag was created by Strength Coach, Josh Henkin, and Physical Therapist, Jessica Bento. Not just so they could work out harder, but so that they could make REAL change.

Both had suffered from athletic careers that left them battered, hurting, and unable to be the role models for their clients and patients they had hoped. Frustrated that other programs and methods weren’t delivering on their lofty promises they looked outside of the typical therapy and fitness ideas.

Instead of looking at just exercises, they examined life. How people moved, how they lived, and how they faced the demands of every part of their life. It became obvious that standard weight and gym practices weren’t cutting it. “Good enough” shouldn’t be in your vocabulary of fitness or better living, that is just settling.

Our Story


2005 was the beginning of a revolution. The Ultimate Sandbag and Dynamic Variable Resistance Training System (DVRT™) were born. For the first time, a training tool and program weren’t created for better training in the gym, but rather for elevating what people did in life and sport….the REAL world!

Over a decade later, while others try to create “sandbags”, we continue to dedicate ourselves to innovation of movement and fitness. The Ultimate Sandbag Training is not just like any fitness tool or sandbag. That is because the Ultimate Sandbag Training is not made to be lifted, it is designed to be moved! Unlike anything else, Ultimate Sandbag Training is designed to match the natural movement of the body. Each intricate design feature is meant to make you feel better in each movement and give you almost unlimited potential in what can be created.

What this means is avoiding the typical aches and pains that most find during the training. Rather, you improve your flexibility, core strength, endurance, and real world strength, not in hours, but minutes. That isn’t an infomercial, but rather a guarantee!

Ultimate Sandbag Training was created to give you a phenomenal fitness experience in a short amount of time. This isn’t a sales pitch, but science (read the University of Wisconsin-Milwaukee study to the right) as the Ultimate Sandbag gives unique instability demands that make more muscles work each repetition. Not only do you work more efficiently, but you can hit angles and positions that are impossible with any other fitness tool. This allows you to create endless exercises not just to avoid boredom, but to continue to meet the demands of real life and sport.

There is a reason that  Ultimate Sandbag Training has become the tool and program of choice for top fitness professionals, therapists, athletes, and our brave men and women in the U.S. Marines, Army, Police, and Fire Departments. Yet, what makes us MOST proud is that the Ultimate Sandbag is right for you, no matter where you are starting! The DVRT system and Ultimate Sandbag allows you to transform ANYWHERE into the best gym of your life.

“Education in my opinion is paramount in this industry! It doesn’t matter how good the piece of gear is, if you don’t know how to use it or even more importantly, if you can’t coach someone else how to use it, it is useless. I have been incorporating the Josh Henkin”s DVRT Ultimate Sandbag training system into my practice for almost 2 years now and I can say without hesitation it is one of the most effective systems I have come across in years. From his principles around progression to coaching, Josh’s system is simple to understand and easy to communicate. As far as  Ultimate Sandbag Training  as a modality, well there are vey few tools out there today that can provide so much bang for your buck! Strength, stability, mobility, Power, Motor control you name it, and you can train it using Ultimate Sandbag Training! I use Ultimate Sandbags almost daily with individuals’ young & old and with athlete’s amateur to professional. Its is one of those tools you almost love to hate because you know once you pick it up, something both challenging & great is about to happen!”
