How does the CFF Adjustable Russian Kettlebell work?

The CFF Adjustable Russian Kettlebell uses a simple lever-based locking mechanism to allow you to add and remove weight plates securely without taking up a lot of time.

To remove plates, place your thumb in the indent to turn the lock dial towards the “unlock” labeled side. Remove the necessary plates, then return the dial to its original position to lock. You can follow the same process when you’re ready to add plates on.

The locking mechanism was simple to use; however, since the plates aren’t labeled, it may take you a few tries to place them on in the correct order. If this becomes an ongoing issue, you may want to label the plates yourself using a permanent marker or colored tape.

What are the Pros of the CFF Adjustable Russian Kettlebell?

One of the best things about this adjustable kettlebell set is the weight increments available to use. Ranging from ten to forty pounds in five-pound increments, this adjustable set gives you a similar set of weights that you would find in a big-box gym or CrossFit box - but without taking up all the space and costing you hundreds of dollars. The versatile weight increments make it easy to tailor your kettlebell to whatever workout you want to do that day.

The locking mechanism is also very intuitive, even if this is the first adjustable kettlebell set you’ve purchased. You’ll feel secure knowing that the weight plates will stay locked in place, even during a high-intensity workout. This added peace of mind gives you the strength to get after your workout without pausing to check and double-check that the mechanism is locked.

Adding and removing weight plates takes very little time, making this adjustable kettlebell set a good choice for those high-intensity interval workouts with little to no recovery and transition time. You won’t have to constantly pause your workout as you add or remove plates from this adjustable kettlebell.

Finally, you’ll appreciate the small details of this adjustable kettlebell. For example, the soft, rubber pad on the bottom thoughtfully protects your floors from scratches. Also, the inclusion of an instructional DVD is very helpful for those just starting to incorporate kettlebells into their workout routine.

What can the Kettlebell Kings Adjustable Kettlebell Improve on?

It would be helpful if the adjustable weight plates were color-coded or numbered so that they were easy to load and unload in the proper order. The plates have to be added in a certain order for the locking mechanism to work properly, and labeling them somehow would make it a little faster to assemble, especially for your first few times using the equipment. However, you’ll be able to learn the proper order quickly, and you can also label the plates yourself if that makes things easier for you.

Also, the weight plates were a little uncomfortable when doing moves that required the plates to rest against your arms for a long period of time. Since the plates don’t fit flush together, the small gaps can pinch your forearms if you’re not careful. A tighter fit between plates would address this issue.

​Who is the CFF Adjustable Russian Kettlebell ​for?

As mentioned above, having labeled or color-coded weight plates would be helpful for further streamlining the addition and removal of weight plates. However, you’ll learn the correct order quickly, so it’s not enough of a con to keep you from buying this product.

You might also feel some discomfort during certain moves with this adjustable kettlebell. The plates are a little sharp on the edges, and they could rub you the wrong way during certain moves in which the kettlebell collides with the body. You might consider learning the kettlebell technique of allowing the kettlebell to “roll” so that it slides over your palm properly; consult with a trainer or experienced kettlebell user to learn the proper form.
