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 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 had tried JKC based on the recommendation of a parent of one of my students. I originally started by attending Saturday drop in classes. I was hooked. I decided to join full time when I I had taken a year off from teaching and it was the best thing I have done for myself.

First and foremost the trainers at JKC are extremely knowledgeable. I feel like they are as dedicated to my success as I am. The workouts are tailored to me, my skills and my goals. This is important. Jon and Thomas truly want the best for their clients no matter what level of fitness they are starting from. I also like being able to book a session at a time that suits my schedule. This also helps keep me accountable. Once the session is booked I am not likely to cancel!

I’m 35 and I started at JKC in November of 2019. I was coming off the win of the Royal St. John’s Regatta in 2019, and our crew was chomping at the bit to be stronger and faster for 2020. The reputation of JKC leached into our group and away we went! Unfortunately the regatta was cancelled due to COVID-19, but I just loved JKC so much I stuck around. JKC is different from other gyms because the level of experience the team has is unparalleled. Jon, Thomas and Craig all mesh well together and mentor me in a way that I know they love what they do and are genuinely excited to guide me towards my goals (and beyond). I really enjoy the atmosphere, the sense of community and all the positive vibes that I experience in every session. There’s never a time I don’t want to go because I’m motivated by the team’s coaching style and I get results.

JKC was recommended to me by a fellow runner. I was experiencing injuries, and feeling weak and fragile. When I started with JKC, Jon asked me about my goals and my focus. I wanted to concentrate specifically on running, and preventing injury. Jon developed a program for me that has enabled me to focus on my form and strength and has been flexible enough to enable me to train for many different races. I have been training with JKC for six years, and during that time I have enjoyed Jon and Thomas’s expertise in a very warm and supportive atmosphere.

My original reason for joining JKC was to get some sage advice to help with my running. I had been looking for awhile, came across Jon, met for an assessment, and was quite happy with how that all went. Apart from the running specific strengthening and conditioning approaches, JKC is different from other gyms as I am a fan of the small group sessions where everyone has their own goals and individualized programs. As well, the run coaching is super. All the coaches go the extra mile to make sure you get the best out each training session. They are fantastic motivators! My favourite memory is deadlifting 330lbs. Making a lot of great friends and meeting some really cool people is pretty high up on that list, too.
