Primal Kettlebells

Onnit’s Primal Kettlebells are a five-weight, primate-themed spin on the standard cast-iron kettlebell — Howler (18 lb), Chimp (36 lb), Orangutan (54 lb), Gorilla (72 lb), and Bigfoot (90 lb) — each cast from a single piece of chip-resistant iron with a sculpted primate face standing in for the usual smooth dome, an oversized handle for grip-strength work, and a flat, wide base for stability. Despite the decorative face, owners and reviewers report the bells are genuinely well balanced, supporting bottoms-up presses, Turkish get-ups, cleans, and snatches just like a standard round bell. The tradeoff shows up at the margins: the protruding face — most pronounced on the Chimp and Orangutan — can bump or clip the forearm during transitions, fast bell switches, and front-rack holds, a complaint raised independently by both a hands-on gym-owner review and Reddit kettlebell owners. Onnit discontinued its entire fitness-equipment line — kettlebells (Primal and Legend Bells), steel clubs, maces, and more — in 2025 to focus on its supplement business; the Primal Bells product page now redirects to Onnit’s supplements homepage, and GymRadar independently labels it a “Discontinued product.” Today’s buyers are shopping the secondary market rather than a live storefront, sometimes at prices well above the original $42.95-$214.95 launch range for out-of-production weights.

What is a Kettlebell?

What kettlebells are

A kettlebell is a cast-iron (or steel) ball with a handle, built for swings, cleans, snatches, presses, and carries — ballistic, full-body work a dumbbell doesn’t do as well. One or two bells cover a lot of conditioning and strength.

What actually matters

  • Cast iron vs. competition. One-piece cast iron is the durable, affordable default. Competition (“comp”) bells are steel and share the SAME dimensions across every weight, so your technique doesn’t change as you go heavier — worth it for dedicated technique/girevoy work.
  • Handle width & finish. Handle diameter and width decide grip comfort for two-hand swings vs. cleans; a smooth handle takes chalk well and won’t tear hands the way an overly rough powder coat can.
  • Coating. Powder coat grips well but varies in roughness; e-coat is smooth and rust-resistant; bare handles need chalk.
  • Single vs. adjustable. An adjustable kettlebell saves space and money if you want a range, but adds bulk and can feel less balanced than a fixed bell.
  • What to buy first. Common starting points are ~16 kg (35 lb) for many men and ~8-12 kg for many women — then add a heavier and a lighter bell as you progress.

Who it’s for

Anyone who wants conditioning, posterior-chain power, and loaded carries without a rack. Start with one well-sized cast-iron bell; add weights or a competition set as your training demands.

Reviews by source

Expert 4.58/5 4 reviews
Reddit 3.5/5 2 reviews 2 threads with Primal-specific content (via pullpush.io, r/kettlebell). "These survived the Camp fire in NorCal...": a set of Onnit Legend and Primal kettlebells survived a house fire essentially undamaged -- "They lived up to the hype and their promise to 'inspire a strength in you previously thought to be mythical'" -- strong durability signal (409 upvotes). "Onnit Kettlebells" thread (mostly about the standard line): one commenter specifically on the Primal line -- "I got the primal ones for some dumb reason. I can't tgu the gorilla face because it hurts so bad and is shaped weird" -- and separately, "Works for swings and cleans but TGU just hurt my forearm a lot and they look cool," echoing the same forearm/edge complaint independently raised in the YouTube sources.
Youtube 3.5/5 3 reviews 3 videos considered with usable transcripts. Levi Jaeckel (Perform 24, gym owner, "Onnit Primal Kettlebells | Do they work?"): functional and genuinely well-balanced -- supports bottoms-up presses and front-rack holds -- but "there is no functional advantage to having these primal bells than to having regular kettlebells"; recommends a standard set first, and flags a smaller margin for error near the sculpted face's sharp edges (Chimp/Orangutan especially). Lebe Stark ("Are PRIMAL KETTLEBELLS From ONNIT Worth It? - Kettlebell Podcast Bits"): "a great piece of art" but "once you advance with your training it's not very useful" -- the protruding face bumps the forearm/shoulder during fast hand-to-hand switches. silversky 545 ("Onnit Howler Primal KettleBell Review"): short, joking clip, still lands on "I highly recommend them," praising the weight balance.

Onnit’s Primal Kettlebells trade the anonymous look of a standard cast-iron bell for sculpted primate faces (Howler, Chimp, Orangutan, Gorilla, Bigfoot) across an 18-90 lb range, and both independent reviewers and owners agree the underlying build is genuinely solid — GymRadar’s 14-gym sample rates it 4.58/5, and a hands-on gym-owner review calls the balance “perfectly engineered,” working fine even upside-down for bottoms-up presses. Versatility is the standout dimension: the wide flat base and single-cast iron construction support swings, cleans, presses, and bottoms-up drills just like a standard bell. The weakest dimension is functionality at the margins — the protruding primate face repeatedly draws complaints, from a hands-on YouTuber and Reddit owners alike, for bumping the forearm during transitions and stinging on Turkish get-ups — and Onnit discontinued its entire fitness-equipment line in 2025, so buying one today means shopping the secondary market rather than a live storefront.

  • +Build quality: single-piece gravity-cast iron construction with a wide, flat, machine-finished base that GymRadar's 14-gym sample rates 4.75/5 for build quality (GymRadar)
  • +Versatility: engineered to stay perfectly balanced despite the sculpted face, supporting bottoms-up presses and Turkish get-ups just like a standard round bell (Levi Jaeckel, gym-owner review)
  • +Durability: an owner reports a full Legend/Primal set survived the 2018 Camp Fire essentially undamaged (r/kettlebell)
  • +Value: the entry-level 18lb Howler listed around $42.95 at launch, competitive with premium-brand standard kettlebells at that weight (Garage Gym Products, GarageGymPro)
  • +Functionality: the oversized handle diameter aids grip-strength training beyond what a standard-diameter kettlebell handle offers (Garage Gym Products)
  • Functionality: the protruding primate face has sharp edges that can bump or clip the forearm during cleans, transitions, and front-rack work, most pronounced on the Chimp and Orangutan (Levi Jaeckel; corroborated independently by r/kettlebell owners)
  • Versatility: no functional advantage over a standard round kettlebell for anyone past novelty/aesthetics — a reviewer who owns both explicitly recommends buying a standard set first (Levi Jaeckel)
  • Build quality: coating chips on contact despite "chip-resistant" marketing claims, and chalk needs reapplying 2-3x more often than competitors (Garage Gym Products, GarageGymPro)
  • Value: Onnit discontinued its entire fitness-equipment line in 2025-2026 (Onnit's own support article; GymRadar independently labels it "Discontinued product"), leaving no live manufacturer purchase path — buyers are limited to the secondary market, sometimes at inflated prices ($150+ observed for the 90lb Bigfoot on Reddit)
  • Functionality: an advanced kettlebell-sport practitioner reports fast hand-to-hand bell switches become awkward with the protruding face and can sting on impact once movements get more demanding (Kettlebell Podcast Bits, Lebe Stark)
