What Is Kettlebell Kings?
Kettlebell Kings is a specialist kettlebell brand founded in Austin, Texas, that has grown into one of the most recognised names in functional fitness equipment worldwide. Unlike generalist gym equipment retailers, Kettlebell Kings focuses almost exclusively on kettlebells — offering powder-coated cast iron, competition-style, and adjustable options across a wide weight range.
What sets them apart from a standard equipment retailer is their integration of training content. Purchasers gain access to workout programmes, instructional videos, and coaching resources designed to help users actually get results from the equipment they buy. This makes Kettlebell Kings less of a shop and more of a complete fitness ecosystem built around a single training tool.
For UK buyers, the brand is available via specialist fitness retailers and ships internationally, though this does affect lead times and costs. Their reputation for consistent quality control, flat-base handles, and smooth powder coating has earned them a loyal following among kettlebell sport athletes, CrossFit athletes, and serious home gym builders alike.

Key Features
Competition-Standard Kettlebells
Kettlebell Kings’ competition kettlebells are manufactured to consistent dimensions across all weights — meaning a 16kg and a 32kg bell are the same size, only heavier. This is essential for athletes training for kettlebell sport or anyone who wants consistency in their technique as they progress. The steel construction, smooth handle finish, and wide window make these a genuine step above budget alternatives. The powder coating on their cast iron range is notably durable and provides excellent grip even during high-rep sets.
Integrated Training App and Programmes
Beyond the hardware, Kettlebell Kings offers structured workout programming through their online platform. These aren’t filler videos thrown together to justify a premium price — the content covers beginner fundamentals through to advanced kettlebell sport preparation. Programmes are categorised by goal, experience level, and available equipment, making it accessible whether you own one bell or a full set.
Adjustable Kettlebells
Their adjustable kettlebell range is one of the more practical offerings for home gym users with limited space. Allowing weight changes via removable plates, these deliver versatility without the cost or footprint of a full rack. Build quality is solid, though purists may prefer the feel of a fixed-weight bell for heavy swings and ballistic movements.
Expert Coaching and Community
Kettlebell Kings has invested heavily in building a coaching and community layer around their products. Email coaching, video breakdowns from certified instructors, and an engaged social community provide ongoing support that most equipment brands simply don’t offer. For self-directed learners, this adds genuine long-term value.

Pricing
Kettlebell Kings sits firmly in the premium segment of the market, and their pricing reflects that positioning. Here’s a breakdown of what to expect:
| Product Tier | Approximate Price | Notes |
|---|---|---|
| Powder-Coated Cast Iron (single) | £40–£90 | Weight dependent; most popular range |
| Competition Steel Kettlebells | £70–£130 | Uniform sizing across weights |
| Adjustable Kettlebell | £150–£250 | Replaces multiple bells; space-saving |
| Training Programme Access | Included / Subscription | Bundled with purchases or standalone |
For UK buyers, it’s worth factoring in international shipping costs and the potential for import duties, which can add meaningfully to the total outlay. UK-based fitness retailers that stock comparable premium kettlebells can often provide a more cost-effective and quicker route to your door.
Who Is Kettlebell Kings Best For?
Perfect For:
- Home gym builders who want a premium, long-lasting kettlebell set and are willing to invest in quality over the cheapest option
- Kettlebell sport athletes who require competition-standard uniform sizing across all weights for consistent technique training
- Self-coached fitness enthusiasts who will genuinely use the integrated training programmes and benefit from structured programming
- Functional fitness and CrossFit athletes who do high-volume swings, cleans, and snatches and need a handle that won’t tear up their hands
- Personal trainers building a studio who want reliable, professional-grade equipment that lasts years without degradation
Not Ideal For:
- Budget-conscious beginners who just want to dip their toes in — a mid-range UK brand will serve you better at a lower entry cost
- Buyers needing fast delivery — international shipping from the US doesn’t suit those who want equipment within a few days
- Casual gym-goers who train infrequently and won’t benefit from the premium quality differential
- Those primarily after a training app — if coaching content is your priority rather than the kettlebells themselves, dedicated platforms like Brute Force Training offer more depth
Our Verdict
After thorough testing, our Kettlebell Kings review lands firmly in positive territory — with some important caveats for UK buyers. The equipment itself is genuinely excellent. Build quality, handle consistency, and coating durability are all class-leading, and the training content adds real value that transforms a purchase into an ongoing fitness resource. However, for buyers based in the UK, the international shipping situation is the elephant in the room. Costs, lead times, and potential import duties make this a more complicated buy than it needs to be. Our recommendation: if you can source comparable Kettlebell Kings stock through a UK-based fitness retailer, do so. The equipment earns its premium price — the logistics shouldn’t get in the way of your decision.

Frequently Asked Questions
Are Kettlebell Kings kettlebells worth the money?
For serious kettlebell practitioners and home gym enthusiasts, yes — the premium price reflects genuinely superior build quality, handle consistency, and coating durability. If you train regularly and want equipment that lasts years without deterioration, Kettlebell Kings represents strong long-term value. Casual users or beginners may find mid-range alternatives more appropriate for their current needs and budget.
Do Kettlebell Kings ship to the UK?
Kettlebell Kings are a US-based brand and do ship internationally, but UK buyers should factor in international delivery costs, extended lead times, and the potential for import duties. For a smoother purchase experience, many UK buyers opt to source Kettlebell Kings or equivalent premium kettlebells through established UK fitness retailers who hold stock domestically.
What is the difference between Kettlebell Kings’ powder-coated and competition kettlebells?
Powder-coated cast iron kettlebells vary in size by weight, which is normal for most recreational training. Competition kettlebells, by contrast, maintain a uniform body size across all weights — only the internal material density changes. This consistency is essential for kettlebell sport athletes who need identical positioning and movement patterns regardless of the weight being lifted.
Does Kettlebell Kings have a training app?
Yes. Kettlebell Kings integrates training content, structured programmes, and coaching resources with their equipment ecosystem. The platform covers beginner to advanced levels with goal-based programming. It’s a meaningful differentiator from pure equipment retailers, though dedicated standalone training apps may offer a more polished digital experience if app functionality is your primary concern.
How do Kettlebell Kings compare to Rogue Fitness kettlebells?
Both brands produce high-quality competition and cast iron kettlebells with strong reputations among serious athletes. Rogue has a broader strength equipment catalogue and established UK fulfilment, making logistics easier for British buyers. Kettlebell Kings’ advantage lies in their training content integration and their specialist focus on kettlebell-specific coaching — something Rogue doesn’t offer as part of an equipment purchase.
