About Onnit

Onnit Kettlebell Review

Onnit is a multifaceted brand that incorporates various health and fitness products for men and women. Onnit made the list of Inc. 500 companies in 2020 and is an industry leader, with over 250 products ranging from peak performance supplements, foods, fitness equipment, and apparel.

You’re probably well aware that exercising can positively impact literally all of the body’s systems. Want to adjust your mood? Move your body! What about improving your memory? Move your body! Want to reduce your risk of heart disease and diabetes? You guessed it…move your body! 

Physical activity not only helps prevent and reduce the risk of cardiovascular disease and cancer, but it can also lessen stress and anxiety, boost happy chemicals, improve self-confidence, increase brain power, sharpen memory, and increase our muscles and bone strength. 

The problem is that only about 19% of the US population engages in daily exercise. If you’re part of the whopping 81% of people who don’t exercise daily but hope to start, the products offered by Onnit might be able to help you reach your goal.

Trainer’s Tip: The worse your mood is, the more important the workout. Stressed? Angry? Sad? Frustrated? Anxious? The best thing to do is move your body!

Onnit founder, Aubrey Marcus, has been featured in major media outlets such as Entrepreneur, Forbes, Men’s Health, and Men’s Journal and hosts a very successful podcast, Ecstasy in Life and Death that garners over 10 million listeners

Perhaps the biggest supporter of the brand is comedian, podcast host, and UFC commentator Joe Rogan, who has given his professional recommendation when it comes to Onnit. His major endorsement is for the Onnit Kettlebell 6 program. This Onnit review discovered that the brand is also loved by professional athletes such as AJ Hawk, Adam Dowell, and Ognjen Topic.

This Onnit Kettlebell review will now take an in-depth look at the brand’s kettlebells, their customer ratings, promotions, and more to help you decide if their products are worth the buy.

Trainer’s Tip: Kettlebells are a versatile, effective, efficient, and easy-to-store piece of equipment in your home. Why? Because it’s an excellent addition to any home gym, acting as a “one-stop shop” for fitness. 

Plus, it can give you unique benefits—the shape of the bell and the fact that you typically use momentum (versus lifting slowly and with control) means you’ll get both cardiovascular and strength-based workouts. The shape of the bell adds stabilization and core challenge, which means you have to move with power.

Overview of Onnit 

Onnit Kettlebell Review

Onnit can be summarized in three words: Total Human Optimization (THO). The founder Aubrey Marcus likes to say, “THO is a commitment to get strong in the places where we are weak, become great in places where we’re good, and shine a light on the stuff we need to take a look at.”

Inspired by his lifelong experience as a multisport athlete and using his background in ancient philosophy, Marcus’ ultimate goal was to create a company that empowered customers to achieve their fullest human potential. His vision was realized in 2011 when he founded the brand in Austin, Texas.

To uphold his philosophy, Onnit live chats with customer service representatives and instructional videos provided by Onnit Academy will help you every step of the way in learning how to use your Onnit Kettlebells effectively for at-home or gym workouts to reach your full fitness potential. 

According to Onnit, its mission is to provide customers with a “holistic philosophy regarding physical, mental, and spiritual well-being.”

Onnit Primal Bells

Onnit Kettlebell Review

Some people like to keep it simple and opt for standard kettlebells, while others want to shake it up with a mashup.

Take the basic kettlebell and put a monkey, ape, or Sasquatch face on it, and you’ve got an Onnit Primal Bell. Each kettlebell is perfectly balanced, featuring durable chip-resistant iron and enlarged handles to enhance grip strength. 

If you’re looking to gain strength but aren’t a fan of traditional bodyweight exercises like pushups, consider this kettlebell. Studies[1] have shown that kettlebell training effectively increases aerobic ability and muscle strength. For example, one study had participants complete 1 repetition maximum (1RM) testing for one-arm shoulder press, leg press, upright row, and handgrip strength. 

Subjects then performed an 8-minute kettlebell VO2max snatch test to determine aerobic capacity. Testing was done before and after the 8-week training program. The results show that an 8-week kettlebell training program is an effective way to improve muscular strength and aerobic capacity.

Trainer’s Tip: For example, to strengthen the wrists and shoulder stabilizers, holding one of the lighter bells up will strengthen your wrists (a weak link for many of us – thank you, computers), the small stabilizer muscles of the shoulder as well as your core. 

We share a common ancestor with today’s chimpanzees, so this collection is all about getting back to your inner beast. Don’t believe me? Google it. Then check out Onnit’s Primal Bell collection:

18lb (0.5 poods) Howler Primal Bell 

As with all Onnit Kettlebell equipment, the Howler Primal Bell is sturdy enough to keep up with your toughest workouts. Unleash your inner beast with the Howler Primal Bell, an 18-pound beast that will bring out the strength of your inner animal. 

The lightest weight in the Primal Bells collection is perfect for an Onnit kettlebell workout beginner. And if you’re looking for more of a challenge, one study[2] showed that 18lb kettlebells effectively improve fitness. 

Not ready to jump to a 30 or 50+ lb bell yet? No problem, Onnit offers their product in a range of weights so you can fit the bell to your current fitness level. 

Trainer’s Tip: Start at your current level of fitness. Don’t be discouraged if the 18lb bell or the 6kg bell is where you are at. The best part of fitness is feeling yourself get stronger, and that comes with consistency. There’s no need to injure yourself on the first try.The Howler Primal Bell is priced at $43.

36lb (1 pood) Chimp Primal Bell 

The Chimp Primal Bell is the next weight up in the Primal Bell Collection. This Onnit Kettlebell review recommends using this to do wings, snatches, cleans, and all other essential kettlebell lifts.

This 36lb Onnit kettlebell will motivate you to push yourself to new heights and power through like any wild beast. Kettlebell training doesn’t just increase your strength; it helps you perform better in your other workouts. 

One study[3] showed that kettlebell training was associated with an increase in jump height, so consider adding this tool to your workout if you want to up your volleyball or jump shot game. The second-lightest weight in the Primal Bell collection is perfect for an Onnit Kettlebell workout beginner moving towards becoming an intermediate. The Chimp Primal Bell rings in at $85.

54lb (1.5 pood) Orangutan Primal Bell 

The Orangutan Onnit Kettlebell is your transition into the big leagues. Level up with this 54-pound ape. This kettlebell is excellent for perfecting your form as you sweat your way through intermediate lifting.

Most of us need a bit of motivation and information on form. Lucky for us, Onnit provides instructional videos on how to use this product, so you will be unleashing your inner beast in no time at all. 

Trainer’s Tip: Make use of the Onnit instructional videos because consistency is much better than perfection. Listen to your body, progress appropriately, and learn the basic moves before you start loading the weight. 

Learning the basics is especially important when trying the more advanced moves like the swing or if you have a history of lower-back issues. Train the body you have at this moment so you can create the body you want. There is nothing like an injury to derail your progress. Get the Orangutan Onnit Kettlebell for $130.

72lb (2 poods) Gorilla Primal Bell

Progress even further with the Gorilla Primal Bell. This 72-pound Onnit Kettlebells gorilla will have you pounding on your chest and letting out primal screams as you conquer your body. This Onnit Kettlebell review found that a reviewer on the website states that the Gorilla Primal Bell is “ideal for single-arm workouts.” 

The Gorilla Primal Bell is perfect for someone looking to move from an Onnit Kettlebell workout intermediate to a master. This Onnit Kettlebell is a dead ringer for King Kong and will set you back $170.  

90lb (2.5 poods) Bigfoot Primal Bell

The end-all beast. The final step in unleashing your workout potential. The Bigfoot Primal Bell is an impressive ninety-pound Onnit Kettlebell and will leave you feeling the burn. This Onnit Kettlebell review found an Amazon buyer who described the Bigfoot Primal Bell as “powerful and a must-have tool for a full-body workout.” 

The heaviest weight in the Primal Bell collection is for those who have perfected their form and are in need of a serious challenge. Get the Bigfoot Primal Bell for $215.
