What Our Athletes Are Saying

“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 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 the Ultimate Sandbags themselves 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 Sandbags! 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!”
