3 design differences you’ll notice on your first rep
Ergonomic Fit - Contours That Work With Your Body
Contoured armrests guide the bell into position—no guessing, no fighting it.
Less impact and smoother transitions so you can train longer and avoid beating up your forearms.
Design to Perform - Lighter Feel. Better Control.
These bells are uniform in outside shape. Weight is determined by how hollow the bell is.
This keeps the center of mass high—making it feel lighter and easier to control with the 35mm competiton spec handle.
Wide & Open Base - More Stable. More Versatile.
A wider base gives you confidence for push-ups, planks, and ground work.
The open rim doubles as a second handle and makes loading chip weights fast and secure.

Hollow Core Design
Competition kettlebells are uniform in outer geometry, so all weights are the same size and shape on the outside but the lighter the kettlebell, the more hollow it is.
Flat Inside
24kg is the heaviest we can make Atlas Line Pro Kettlebells since they are close to filled at that point.
The Apollo line has a larger outer geometry, so a 32kg Apollo looks like a 24kg Atlas… almost solid, where an 8 kg is completely empty.
Regardless of the weight, the inside is flat, to accommodate easy and strong attachment to our Level-Up Magnetic Chip Weights.
USA Atlas Pro Kettlebells
Made in USA Atlas are the compact Pro Kettlebell, better fitting to smaller bodies and easier to swing two between your legs. Available in 4kg Increments from 4kg-24kg (9lbs -53lbs).
USA Apollo Pro Kettlebells
Made in USA Apollo Pro Kettlebells are similar in size to traditional competition kettlebells. They're extremely comfortable and designed for larger framed bodies. If you're 5'8" and taller and/or to lift heavier than 24kg, choose the Apollo Line! (8kg /18lbs-32kg/70lbs)
What to Expect from Our Kettlebells
We’re temporarily pausing presales on our Made in USA kettlebells while we finish the remaining steps needed to get foundry production up and running.
A limited number of Made in USA Apollo and Atlas kettlebells are still available now, including select individual listings and Factory Seconds. Check the current product listings and Factory Second Pro Kettlebells collection for what’s still in stock.
Once the remaining inventory is gone, Made in USA presales will stay closed until the next production run is ready.
Pro Kettlebell’s patented, contoured arm rests promote proper technique by guiding your arm to its most ergonomic position. Unlike other kettlebells, where so much of the weight presses into your forearm at one spot (causing painful bumps and bruises), this contouring spreads the weight of the kettlebell across your forearm. Buy kettlebells from our online store and you'll be able to lift more weight and/or lift more often without injury.
All "Apollo" kettlebells (our larger kettlebells) and all "Atlas" kettlebells (our smaller kettlebells) are the same size and shape regardless of weight.
This consistency allows you to keep your technique the same as you move between lighter and heavier bells, resulting in seamless and safer workouts.
The weight of each bell is determined by how hollow the kettlebell is. The lighter the kettlebell, the more hollow. The heaviest weights in each line are nearly solid, leaving a fingertip rim.
We designed the bells to be flat on the inside so you can add one of our magnetic chip weights.
This design keeps the center of mass as high as possible, which allows for maximum control while maneuvering the kettlebell. You'll find your ballistic kettlebell moves like cleans, jerks and snatches much cleaner when you order kettlebells online with Pro Kettlebell.
The Flat Spot
The flat "face" of the Pro Kettlebell allows it to lay on its side and become a stable platform for exercises like kettlebell pushups.
Also, in case you were to lose control and drop it during a swing, snatch, or while kettlebell juggling (it's a thing!) the flat spot keeps the kettlebell from rolling and potentially damaging something or someone in its path.
The horns (the parallel sides of the handle) are designed for ergonomics while holding the kettlebell both right-side up and upside-down. This makes it more comfortable and versatile than other kettlebells.
The handles are 34mm (Atlas) and 35mm (Apollo) and come unfinished so they hold chalk beautifully.
They’re polished smooth on the top and underside, but we leave a little texture on the sides for extra grip that makes them easier to hold and feel lighter when swinging.
The base ring (the bottom) of a Pro Kettlebell is proportionatley wider than other kettlebells, providing more stability when performing exercises like renegade rows where you're planking on the handles.
This base ring also has a smooth edge so you can grip it, allowing for an extra hand-hold on the bottom.
This is something unique to our kettlebells, and just one of the elements that make our kettlebells for sale the best of the market.
