Unique Features Of The Onnit Brand Kettlebells
Onnit kettlebells bring a fresh and unique design to the kettlebell market. Not only are their Standard range of kettlebells affordably priced, but their Primal range offers an element of fun to enhance your workout routine. Aside from an unusual design, Onnit kettlebells also boast a range of useful features. Let’s take a closer look!
Gravity Cast For More Consistency & Durability
Gravity casting is the best method used to create kettlebells. Molten metal is poured into a mold, and, as the name suggests, gravity works to create an accurately weighted kettlebell. However, when gravity isn't used to cast kettlebells, the weight and dimensions of each kettlebell can differ. This can cause them to be inaccurate in weight, even when made in the same batch.
Powder Finish For Better Grip
When it comes to coatings, powder coating is the most durable option available. Onnit kettlebells offer a smooth finish while still providing enough texture for an adequate grip. This means you won’t struggle with a kettlebell slipping out of your grasp when your hands get sweaty. In addition to providing excellent grip, the powder coating helps protect the kettlebell against corrosion.
Color-Coded for Ease of Use
When Onnit redesigned their Standard range of kettlebells, they included color-coded bands at the base of each handle. This is a truly useful feature that allows you to quickly and easily identify the weight you’d like to use - without having to pick up or tilt each kettlebell to check its weight stamp. Kettlebells are usually lined up together, often with the labels facing the wall, so having the bands visible from above makes a big difference!
Sturdy Handles For Safe Use

Since kettlebells are designed to be lifted and swung by the handle, they must be able to tolerate these movements.
The Standard Onnit kettlebells feature the same powder-coated finish used on the body for the handle.
The finish offers an excellent grip while still being comfortably smooth and free of any sharp edges.
The last thing you want when using a kettlebell is for the bottom portion to fly away from the handle during an exercise.
Since the Onnit kettlebells are made using a single cast, you don’t have to worry about this ever happening!
Unique Designs
When it comes to unique design, this is what sets Onnit apart from the rest. While the Standard range of Onnit kettlebells offers a plain black finish with color-coded bands, their Primal and Legend range brings something completely unique and fun to your workout. From a variety of ape designs to an assortment of mythical creatures, Onnit certainly wins the award for most unique designs!
Versatile
Kettlebells are the ideal tool for strength training. Not only are they the best choice for explosive movements, but they can also be used in the place of dumbbells. This means that you can do all of your dumbbell workouts plus a whole lot more. With just one pair of kettlebells, you can do strength training as well as HIIT training. This makes them a truly versatile option to include in your home gym setup.
Onnit Kettlebell Range Reviewed
Product Specifications
Material | Solid Iron |
Sizes Available | 6-32 kg |
Finish | Powder-Coated |
Earlier, we mentioned Onnit’s reputation for offering fun, creative designs within their kettlebell range. If you’re not already familiar with the range, Onnit offers standard round kettlebells and some unique options - like their Primal range as well as the Legend range.
Construction
Regardless of the design, all of Onnit’s kettlebells are made of solid iron and perfectly balanced. They are built tough and free from visible weld lines or plugs. You can expect the same level of craftsmanship and durability throughout every range of Onnit kettlebells.
Design & Finish
As mentioned, each range features a distinctly different design. The Primal range features a selection of ape-themed faces, while the Legends range offers a selection of various mythical/ fantasy characters.
Aside from their design differences, the Standard range features a powder-coated finish to ensure a high-quality, smooth surface that offers excellent grip and rust resistance. However, the Primal and Legends range features a chip-resistant iron without the powder-coat finish.
Additionally, all of the kettlebells also include a machine-finished flat bottom. This adds stability and ensures they don’t roll around when set down on the floor.
Kettlebell Handle
The handles of the Primal and Legends range of kettlebells are designed to be larger than average, allowing you to further enhance your grip strength. Most people find this to be a positive rather than a negative.
However, if you’re someone with smaller hands, there’s a possibility you might find the larger handle size slightly more uncomfortable to hold.
Aside from thickness, the handles themselves are easy to grip, even with sweaty hands. Unlike other budget kettlebell handles, Onnit has ensured that the handles are smooth and won’t cut your hands during your workout.
Performance
Taking a look at performance, Onnit kettlebells exceed expectations both with or without chalk. If you prefer to skip out on using chalk with your kettlebells, you’ll appreciate the decent grip offered by the chip-resistant iron finish. While thicker than the powder-coat finish on the Standard kettlebells, you will still be able to have a secure grasp on the kettlebell throughout the workout. Using the kettlebell with chalk, however, certainly adds even more grip and is ideal for people who experience very sweaty palms.
Sizes Available
Within the Standard range, you have a selection of the Dark-Blue 6kg, Pink 8kg, Light-Blue 12kg, Yellow 16kg, Purple 20kg, Green 24kg, Orange 28kg, and the Red 32kg. As mentioned, these kettlebells feature an all-black finish with their allocated color added to the base of the handle.
Within the Primal range, you have the option of an 18lb Howler, a 36lb Chimp, a 54lb Orangutan, a 72lb Gorilla, and a 90lb Bigfoot design. The Legend range includes a 12kg Harpy, a 20kg Cyclops, and a 28kg Werewolf design. Additionally, Onnit also stocks other designs like the 18lb Brain Goblin Zombie or Star Wars-themed kettlebells from time to time.
Price
Taking a look at pricing, the Onnit Standard range offers an excellent price that is competitive with other brands. For example, you can expect to pay just under $45 for a 12kg (26lb) Onnit kettlebell, while a Rogue 26lb kettlebell will knock you back around $60.
However, since the Onnit range of kettlebells also offers something completely unique and different, you should expect to pay a far more premium price for the Primal and/or Legend range. For example, the Onnit Primal Kettlebells start at around $42 for their 18lb weight and go up to $215 for their 90lb kettlebell.
Comparisons With Onnit Kettlebell Alternatives

If you’re wondering how Onnit kettlebells compare with other brands, like Rogue or Kettlebell Kings, we’ve got you covered! When it comes to design, it’s a no-brainer that Onnit’s range of fun designs wins in this category!
In terms of ease of use, you might think that doing certain movements with the Onnit Primal series would be uncomfortable. However, Onnit ensured that the back-side features the same shape as any other kettlebell while still being balanced. This means you’ll still be able to do all of the same exercises that you would with a standard round kettlebell.
Unlike both Onnit and Rogue, Kettlebell Kings offers free shipping on their kettlebells for orders above $150. However, looking at the pricing of the kettlebells themselves, Onnit offers the best value for money and is the most affordable option with their Standard range. In terms of quality, all three brands are made using a single cast and are coated with a powder coat finish.

Onnit Kettlebell Workouts For Beginners
The Onnit Full-Body Kettlebell Workout For Beginners offers simple yet highly effective exercises. When using a kettlebell, there are five basic movements involved. These include the press, row, hip-hinge, squat, spinal rotation, and rotation-resistance. Designed by Onnit’s Chief Fitness Officer, John Wolf, the beginner workout plan might be simple and suitable for beginners, but it’s certainly not an easy workout plan! The plan itself features the following exercises:
The purpose of this workout plan is to help beginners improve their familiarity with using kettlebells while also building strength and endurance too. While the plan foregoes movements like a full kettlebell swing, the chest-loaded swing stands as a more beginner-friendly alternative.
Once you’ve gained the confidence, you can then move on to more advanced movements like the full kettlebell swing, as well as cleans, snatches, and more. To do the Onnit Full-Body Kettlebell Workout For Beginners, all you’ll need is a single kettlebell. Depending on your strength level, an 8kg or 18lb kettlebell is recommended for women and a 16kg or 35lb kettlebell for men.
