The Sorinex Center Mass Bell brings an entirely new standard to the gym. The product’s original design is the work of gym equipment mastermind Donnie Thompson.
We recently reviewed the similar Rogue Thompson Fatbells and found them to reduce shoulder sheer while completely replacing dumbbells for many of our favorite bench and floor-based workouts.
In true Sorinex fashion, the company has taken the idea of the Center Mass Bells design and improved upon it. Sorinex offers a ductile iron design that is stronger than cast iron, ensuring drops down lead to cracking and other issues. Sorinex is so confident in its design that a limited lifetime warranty is included with every Center Mass Bell purchase.
The Center Mass Bell is balanced perfectly on three planes, this helps produce a natural gross load for easier movements. The bells are so perfectly balanced in shape that they are easily used on smooth surfaces for various exercises that require rolling the bells back and forth.
While the Rogue Thompson Fatbells are excellent additions to any gym, we found that Sorinex’s decision to leave both sides of their CMB’s wide open allows for additional exercise options we can’t perform with Rogue’s closed system.
As one reviewer on this page has pointed out, because the center mass bells are hallowed out, by design, they do tend to run larger than a standard kettlebell. If you plan on placing heavier sizes on our kettlebell shelf, remember you’ll have less space because of the design factor.
If you’re looking for a more connected kinetic chain, Sorinex promises to deliver and users agree that the delivery is close to perfection.
The Center Mass Bells start at 5 pounds and increase in 5 pound increments until 50 pounds at which point they increase by 10 pounds to 100. This is a nice advantage over other options that jump non-traditionally between sizes.
In our opinion, you could replace all your dumbbells with the Sorinex Center Mass Bell and you would never look back.
The Sorinex Center Mass Bells are my new go-to
I struggled to find any workout equipment during lockdown and stumbled upon these completely by accident. I ordered a pair from Sorinex and 10 days later they arrived. I’m really glad I bought them almost by accident. After watching Sorinex’s on-page video about exercises that can be completed with these center mass bells I was off to the race. I will probably never go back to dumbbells again. Sadly, they are out now and I have to “check back daily” as their website says to eventually buy more. Highly recommend!!!
I have both dumbbells and kettlebells but had a sense that CMB might have some of the advantages of both. They are typically sold-out, but I received an email from Sorinex that they were available and immediately bought a pair of 50lbs. As I tend to go more with traditional weight-training movements like bench press and row, I tend to prefer my Iron Grip dumbbells (which are pretty awesome) but I really like the way that I can grab a single kettlebell or a pair and get a complete workout anywhere in a short period of time. Typically with kettlebells, I tend to do grinds (presses, squats, etc) more than ballistics (swings, snatches), so having a more dumbbell-like kettlebell, if that makes sense, seem custom-made for me.
