Last weekend, I was fortunate to attend the DVRT (Dynamic Variable Resistance Training) Level 1 and Level 2 certification hosted by Josh Henkin, a strength coach from Scottsdale, AZ and creator of the Ultimate Sandbag. I knew this course was more than just about “a bag of sand” but didn’t expect to see so many concepts integrated together.

I’m proud to say that I passed my exams and am now Level 1 & 2 DVRT certified! Whoop whoop!

What does this mean? It means I have the training to successfully integrate sandbag training into a traditional fitness program and still teach proper fundamental movement patterns such as the squat and hip hinge while also enforcing core and shoulder stability. Using the Ultimate Sandbag may enhance the teaching of these movements and body positions compared to traditional fitness equipment.

For my top 3 take aways from the DVRT course, check out my guest post on Josh’s Ultimate Sandbag Website:

I also put together this Ultimate Sandbag complex which kicked my butt yesterday! Here’s what I did:

A1. Lateral Deadlift to Clean
A2. Rotation Lunge to Clean
A3. Rotation Lunge to Clean
A4. Cossack Squat

 
As for the reps/sets, I performed 3 reps per exercise per side per set and did 5 total sets with 60-seconds rest. I used a 3/4 full water bladder inside my Ultimate Sandbag – you can hear the water sloshing around in the video (below). This increases the instability of the implement as you can see my weight shift from time to time during the complex. This increases the complexity of the exercises and forces by body to react to the always changing water position in the bag.

If you want to add sandbag training to your program, I recommend Josh’s Ultimate Sandbag. They are made from a durable vinyl with easy to grip handles. Sand filled or water filled options are available. Discloser – I am an affiliate but remember, I only support the best products available.

That’s a wrap.

I’m 29 and I just had my 3rd Liftiversary 🥳 at JKC. I chose to train here because of the great word on the street and the fact that at lululemon, we’re encouraged to support our local community. My day-to-day routine is very busy, and I love showing up and having to think very little about my workout. The vibes are always good, my music choice is usually accommodated, and the bys are incredibly supportive and compassionate, helping me reach my goals (even when I had a broken hand). I also get to be my weird self, and am embraced fully.

JKC was recommended to me by my good friend Casidhe Dyke. Cas had been training with JKC for a while, and both he and his father had seen great results from the personal training that Jon and Thomas were giving them. I was and still am primarily a triathlete and I’ve always struggled with injuries. I was talking to Cas about incorporating more strength training in my program to try and prevent injuries going forward and Cas suggested that I give JKC a try. I reached out to Jon not long after, and the rest is history! After working with Jon and Thomas for a few months, I was getting stronger, faster, and most importantly, I was staying injury-free. I ended up being able to train the whole season without significant injury and posted a personal best at Ironman Copenhagen in 2018. A big part of that was due to the strength training and coaching I received at JKC.

I was looking for something to augment my 20+ year yoga practice with a focus on strength conditioning. I am friend’s with Jon’s sister in-law and over the years always heard great things about JKC, especially with respect to the top quality trainers they have and programs they run. After talking to Jon about my goals, and hearing his thoughts on a training plan, I knew that this was going to be an awesome experience … and it sure has been. JKC stands out from other gyms because of the attention to detail, the high quality of the staff and the facilities. Also, the amazing people that train there. And no one posing and taking selfies. I’m 41 years old and I started in Dec 2021.

I’m 34 and started at JKC in 2015. My wife joined while I was working away in 2015 and started making amazing progress while also completing exercises I’d never perform on my own. I felt I was missing out so I signed up. JKC helps in establishing goals while also having clear direction of what to do, and how, in each session. They also measure your progress which is another means of motivation! At other gyms I wouldn’t have a clear plan and would just use whatever equipment was free, it was hard to see any results. Between setting some personal bests and making good friends its hard to identify a favorite memory.  One that does come to mind was when I hit my target goal/PB in both bench and squats in the same session, big day.
