About
Kettle Theory

Kettle Theory, Inc. was founded along with the invention of the KettlePod adjustable kettlebell and will be home to new, innovative products already in the pipeline. 

Invention of the KettlePod

The KettlePod adjustable kettlebell was born out of necessity…  I wanted to start using kettlebells when working out at home.  But I didn’t have the money or space for a full set of kettlebells, so I shopped around for “adjustable” kettlebells. And I found plenty…  but none of them made any sense. 

Every adjustable kettlebell on the market suffers from at least one of three fundamental flaws:

  1. Cheaply made  and don’t look or, most importantly, feel like a kettlebell;
  2. Changing weights is too time-consuming and tedious.
  3. Can’t use your own weight plates,  even if you already own them.

So, I built my own. It took two years of designing, building prototypes, and redesigning…  but finally, we have the KettlePod. It is truly the only adjustable kettlebell on the market that makes sense, and it addresses all the flaws I found in the existing products.

Why the KettlePod

What sets the KettlePod apart:

STRONG

Made in America from aluminum, steel, and cast iron, it looks and feels like a kettlebell.

SIMPLE

The patented design allows you to change weights in seconds so your workouts don’t get bogged down by funky equipment.

SMART

Compatible with Standard and Olympic weight plates — there is no need for proprietary weight systems. If you already own weight plates of any kind, you can use them. (And if you don’t have any weights, not a problem — you can get a set with your KettlePod.)

Have fun out there!

A kettlebell is always the most versatile piece of exercise equipment in most gyms. The KettlePod however, takes this to the highest level of personalization and performance. Put me on a desert island, my KettlePod is coming with me.

The KettlePod has been an awesome addition to our gym. We had one full set of standard kettlebells and then added three KettlePods to expand our capacity. They're tough, easy to use and members love them... some don’t even use the "traditional" kettlebells anymore.

The KettlePods have been a great addition to our physical therapy practice. We have a lot of top-flight equipment at our facilities, but we needed additional capacity and flexibility with our free weights – including the ability to use heavier loads with some clients in certain scenarios. But we also didn’t have space to bring in a lot of weightlifting equipment, so the KettlePods have been the perfect solution. They give us the flexibility and capacity we were looking for, but for a fraction of the cost and using a fraction of the space we would have otherwise.
