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.

-JK

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.

I chose JKC originally to help prevent rowing injuries. I’m a rower and we won the St. John’s Regatta in 2019 but I rowed through a rib stress fracture and missed significant time in the boat during the racing season. Training at JKC consistently since the pandemic helped me stay injury free this year and made me the strongest I’ve ever felt, which helped me help my team win the 2021 St. John’s Regatta! Jon adds variety and mixes the exercises up well so that the workout goes by quickly and strength is gained. The gym is very personable and I like the eclectic mix of people that are there. JKC is much more intimate and personal than other gyms.

I am the oldest client at JKC at 79 years, soon to be 80. I started training at JKC July 2021. I started at JKC because two of my three sons Justin and Michael and their partners Andrea and Keir and one of my doctors recommended JKC. They all train at JKC Now my wife Linda trains at JKC too. My third son Jonathan lives in Kingston. There is a congenial community atmosphere at JKC. People are introduced to each other. There is effective personal training at JKC.

I originally joined JKC because I was anxious about passing out and embarrassing myself since I hadn’t weight trained in a while and I’d hoped to find somewhere sympathetic. My husband @terry_hussey had been training at JKC and his success there made me miss the achievement you feel from a good workout. I went to meet Jon and immediately knew it was going to be a safe space for me. I was never judged for the fears I had and where I was starting from. Jon and Thomas made sure to check on me often, and found a way to challenge me but make me feel secure at the same time, and Terry and I were able to book sessions together, so working out became a shared win for us!

JKC is different from other gyms because of the personal growth you have outside JKC (the sessions inside JKC creates a great positive feedback loop!). You gain self confidence, learn how to show up for yourself, meet a community of newfound friends, and get the support of your trainers who are behind you 100%. I’ve left a scattered workout so proud of myself I’ve honestly shed a tear in the car on the drive home. JKC is the mental health relief valve I need to stay positive, and keep my anxiety and health related fears at bay.
