Teaching Functional Movement Strength Education Since 2008

Our Dynamic Variable Resistance Training program (DVRT™) has become a standard in the fitness industry for teaching and educating fitness professionals, physical therapists, and strength coaches on true functional training. We have provided top level continuing education for over a decade and 13 countries worldwide. Our DVRT program has been a focus of top industry conferences as well, but we understand there are many questions about what DVRT really is all about. Below we are going to answer some of the top questions about DVRT, if you don’t see your question please email us at info@ultimatesandbagtraining.com

“This was one of the best training sessions I have ever attended, and I am so grateful I found you guys. You all are an incredible team! Josh is an incredible speaker, instructor and all around communicator, he kept us interested for the entire day with great information, demonstrations and humor – to ensure we were having fun. I have been watching your videos for the past year and self-teaching as much as I could, but holy cow, nothing could have prepared me for the class. I am rediculously excited to start incorporating what I learned into my own training, and then once I feel more confident, into my classes. “-Anne Mathie

We understand why many people at first glance might think that DVRT is simply a users course about our Ultimate Sandbag. However, that couldn’t be further from the truth!

“The DVRT Certification isn’t a “how to do sandbag training program”, it will completely change how you see real world fitness and give you infinite ways to solve your clients’ needs!”

– Brendan Startz, Owner Full Potential Fitness

Our goal with DVRT is to educate attendees on how the body works, how the body creates real life movement, and why we see so much dysfunction. Establishing the why’s, we create solutions in building extensive progressions of exercises. We not only cover over 20 movements that you can immediately use with your clients, we provide you the system to make every program customized for any training environment.

Whether you are training one on one, small group, or team based training, the DVRT system is designed to give you the ability to work with a wide variety of abilities while providing a customized approach. The DVRT instructional concepts provide you a feeling of almost infinite exercises, but more importantly, you learn the simple cues that provide you a huge impact to your clients’ success!

“Amazing Certification!!! The Level 1 & 2 cert was amazing! There was a ton to learn and all of the coaches were awesome. The system covered in the certification is instantly applicable and can easily be applied to what I’m currently doing in my programming to make it even better! I definitely recommend this to ALL fitness professionals.”

– Craig Shinkarik, Owner Forever Fit



Our DVRT workshops are a great introduction to our DVRT system and why it is so impactful to getting people results so fast and how it is so different than anything else you have experienced. Being a 4 hour program, we highlight some of our most popular DVRT drills and how they fit into the larger scheme of a functional fitness program.

The DVRT certifications are designed to help coaches or enthusiasts excel in the skills of applying DVRT. Not only do we delve into far more detailed functional fitness concepts, there is more time exposing the student to the many layers of progressions and programming of DVRT. We get into the heart of proper cuing, proper movement identification, and students are measured in their ability to apply these concepts in both a written exam (that is done at home) and our DVRT Clean and Press test.

“I highly recommend the DVRT System and program to everyone I meet! The DVRT system has had a profound impact not just on my personal fitness but on my professional business as well! As a business owner the DVRT system is about finding solutions and identifying strategies to get my clients the results that they want. Whether it’s increased performance and fitness, or strength and fat-loss, DVRT helps identify solutions to get them to their goals.”

– James Newman, Owner of Quest Fitness, Guilford, CT

“This is a system that will forever be teaching me through feedback and evolution of movement. I’ve already improved my kettlebell skills because of the DVRT. Thank you for this great opportunity! “-With Much Gratitude,Charles 



We always want to be transparent about what we do at DVRT because everything is done with great intent. Before the implementation of a physical standard, most attendees had not even touched an Ultimate Sandbag. This made the program much more limited because every concept was so new to the student. Having more familiarity with the tool allowed us to spend more time on building the system, cover more exercises, and offer more layers to what the program can do for one’s training business.

There is also our desire to quantify the quality of one’s coaching. We believe whether you are coaching yourself or others, there are three key qualities of being a good coach.

-The ability to design a program that achieves a specific goal. The intent with the Clean and Press test is that it will take a 4-6 week program to achieve the goal. One shouldn’t be able to pass on their first attempt of the standard.

-Understanding how to put several movement patterns together and the proper performance of them. The Clean and Press involves hip hinge, plank, pushing, pulling, mobility, strength, and power-endurance. So many key functional fitness qualities.

-The essence of coaching is the ability to problem solve. We want to see coaches that may have technique flaws, they may lack mobility in some part of their body, they may need to increase certain fitness qualities. Can you identify your needs and create a solutions based upon them.

Some may think a standard like this is about toughness, it is not! It is about all the elements of good coaching!

Each program is an 8 hour one day program that is designed to give the most to the student. Restoration can be thought of as our corrective exercise program. We help students understand what functional movement means, how to build the proper foundation, how the kinetic chains work, progressions to increase mobility, stability, and total body strength and awareness. Restoration goes a long way to helping the big 3 joint issues of the body; knees, shoulders, and low backs.

“This was by far one of the most, if not the most, valuable CE that I’ve done since I’ve been in the industry for the last 6 years. I did the DVRT Level 1 this past January and I knew within a few minutes of being there that this was going to change the way I think about fitness. The Restoration program took that to another level and I feel like EVERY trainer/coach out there should go through it so they can understand more about the human body and a system for core progressions/screens. This was incredible. I’m also good friends with Cory Cripe and a few other Master trainers, but Cory and I live in the same city and I love talking DVRT with him. Thank you for all you and Josh have done and continue to do to help our industry!!”

“The DVRT Restoration course is by far the most thorough online course I’ve ever taken in the fitness industry! The scientific foundation for the program integrated with functionally applicable movements makes this a course that can be implemented immediately. I greatly appreciate the included videos that I can always refer back to as a resource. The detailed explanation of the movements, as well as the regressions and progressions of the movements, has helped my 30 Minutes of Everything program better progress clients. I use these DVRT principles every day!”

Our Level 1: 
Foundations of Functional Training is built to be the perfect combination of strength, corrective, coaching, and true functional fitness. Based on movement concepts taught in Restoration, Level 1 brings us to more challenging strength training that will both change how you see familiar movements and bring you a whole new world of fitness solutions. We cover how to establish, progress, and build the 7 primal movement patterns that will instantly improve strength, mobility, and overall performance.

“As a physical therapist, you may be interested to know that I have made attempts to lift overhead, over the last couple years. All have been with bad pain. Having been recently diagnosed with a torn labrum, , I’d basically thrown in the towel on having overhead strength, but this past weekend changed that. DVRT is the REAL deal!”

-Pete Cathey, Physical Therapist

People often inquire the most about what is the difference between Level 1 and Level 2. While it is easy to say it is “more advanced” that doesn’t do the difference justice. Our Level 2: Advanced Movement Strength Concepts is the collection of principles of Restoration and Level 1 to be put together and progressed to their full potential.

Level 2 is corrective, it is strength, it is coordination, it is mobility, it is fluidity, it is the culmination of all functional fitness concepts set-up in a systemized manner so that people can benefit from the great drills and ideas that Level 2 is based upon. Unlike some programs that make things unnecessarily difficult, or aim for novelty for effectiveness, Level 2 is a clear continuation fo all the ideas, strategies, and progressions set forth in Restoration and Level 1. Your world of functional training will never be the same and you will find how extensive real world strength training for any individual!

“If you are not using DVRT, you are falling behind in the fitness industry!”
