Onnit is mostly known for their supplements and for being liked by Joe Rogan, but did you know they also make an excellent kettlebell?

I bought Onnit’s 20kg (44lbs) kettlebell and have been using it daily for a few weeks now.

It’s a no-regrets option for anyone looking for a well-made kettlebell at a reasonable price.

Onnit, the company

Onnit was founded in 2010 in Austin, TX and sells supplements, protein powders, on-demand home fitness programs, kettlebells, and apparel.

It also hosts events and fosters an active online community of people who want to improve their lives by getting fit, eating better and getting rid of their bad habits.

In 2021 Onnit was acquired by Unilever, a large, international consumer goods conglomerate that’s based in London. The strength of Onnit’s brand and its potential to keep growing fast is probably what drove Unilever’s purchase.

The kettlebell: specs

I got the 20kg kettlebell. Since Onnit doesn’t publish specs for its kettlebells apart from weight, the numbers that follow are from my measurements (and any inaccuracies are mine):

  1. Weight: 20kg (44lbs)
  2. Handle diameter: 38mm (1.5in)
  3. Distance between handles: 133mm (5.25in)
  4. Handle outside distance: 206mm (8.125in)
  5. Handle vertical space: 70mm (2.75in)
  6. Total height: 254mm (10in)
  7. Diameter: 168mm (5.625in)
  8. Base diameter: 120mm (4.7in)

Onnit’s kettlebells are powder-coated and each weight is assigned a different color.

I imagine the color-coding is more useful for gym owners who have multiple kettlebells and need to keep track of them. I doubt most people just working out at home will have enough kettlebells to have a hard time telling them apart. Still, it looks nice.

What I liked

There are no casting defects and the finish is excellent. The powder coating feels great and takes chalk well.

There’s ample space between the handle and the body. I like how wide the base is because it provides a lot of stability when doing floor exercises, such as push-ups or planks using a kettlebell.

What I didn’t like

My only complaint was the shipping. When the box arrived, it was trashed. Really, you’d be forgiven for passing it by on the street and assuming it was garbage.

Inside, the kettlebell was loosely packed with just a couple pieces of cardboard for padding. The result was that it came with noticeable scratches and scuffs.

This isn’t a big deal, given that kettlebells are very durable and destined for a future of hard use. But it was annoying that so little care was taken to ship the kettlebell in good condition.

Worth it?

Definitely. If you’re looking for a kettlebell, Onnit makes good ones. This 20kg one cost $69.95 plus $28.26 in shipping.
