Definitely the best Kettlebells

Having bought numerous makes of kettlebells over the past year, trying to find a decent shaped one at a good price. I had given up. Then I found ‘Northern’. I wish I had known about them sooner. Their kettlebells are the perfect shape and size. Those who use them will know how important that is. The grip is fantastic for all exercises. Easy to grasp when switching between hands. They’ve made training much more fun and easier. I’m gaining strength at increasing over 2kg per month in all exercises. I wasn’t doing this prior Northern as the kettlebells I used were just too bulky.
Northern kettlebells take up less than half the space the other brands were taking.
Fast delivery and great service.
I’ve uploaded a 20kg Northern KB against my older one so you can see the size difference.

Two out of three isn't so bad

I bought 8kg, 12kg, and 16kg kettlebells, the 8 and 12 are perfect but the 16kg came with a dent/chip and surrounding the dent is what looks like the remains of a sticker that was removed. I thought, two out of three isn't too bad. Apart from that, no complaints, the delivery was fine, and so was the packaging. I'm quite sure I'll order again when I need to.

Very disappointed

Already owning northerns 4,6,8,12,16 and 20KG kettlebells and being super impressed with the quality and finish I purchased the 24 to complete the set.
The finish is terrible, the painting is shocking and there are multiple sharp shards sticking out on the handle. This shows a clear lack of quality control.
I did send an email to northern who agreed with me that the item they sent me was sub standard and offered a return and replacement, but by the time they had received and inspected my return then processed and sent a replacement it would be too late for what I actually needed it for.
Left me really disappointed and unsure if I’ll use northern again.

Waste of time, items won’t arive

Ordered a set of Kettlebells and after a week messaged them to say the haven’t arrived, then said they will send some more out which never materialised , then said they were delivered, they were not.
Absolute waste of time, no refund and no kettlebells.
Order at your own Peril.

Good quality cast-iron kettle bells like you would find in a commercial gym. Quick fast delivery less than 2 days considering I opted for the standard delivery. Very happy

Don’t know how it passed quality control!

Really disappointing with the quality and the lack of response from my emails!
My product came with sharp and zagged nibs in several areas, the painted stripes are rough, misshapen and grazed.

Absolute class! Iron cast kettlebells I got on offer during the Black Friday bonanza! Pure solid iron cast! Perfect / can’t wait to evolve in the KB world! I also got the yoga mat that folds in three stages - quality product. Actual cushion - very comfortable. Thank you!!!

High quality, budget friendly kettlebells!

I ordered these after returning a set of Taurus vinyl coated cast iron kettlebells, that were just a terrible design. And these cast iron bells from Northern Gym Equipment are far superior, I just love everything about them. The quality is great, you get exactly what it says on the tin, the design in terms of handle thickness and space between handle and bell is in the correct range, unlike the Taurus bells I returned, and best of all, they came at an amazing price. I also had a 20% discount on top which really put the cherry on the top.
They work well for all main movements like swings, snatches, cleans, squats, etc. And I couldn't recommend them enough!

Kettlebells good.....

The kettlebells are good, smooth surface, the packaging and delivery is another matter which brought the rating down. Bought 3 bells all meant to be delivered by Evri and had this notification. I then got a notification from DHL which I thought was a scam (emailed northern and all they gave me gave was Evri tracking info) but came home to find my parcel. Was quite concerned as two bells had been taped together so the poor delivery guy had to man handle 22kg in a small odd shaped package. I then had to split the bells to get them upstairs to my flat. The 3rd bell was delivered by Evri but the packaging had broken 10kg bell and someone had wrapped in parcel tape so not secure. Very disappointed really and still can't understand why two bells were strapped together.

Solid and dependable

Ordered a couple of kettlebells. Arrived timely though separately to each other. These are quality solid cast iron kettlebells with traditional ergonomic handles unlike some that are filled to weight making the bell imbalanced.
Already referred others to Northern and when renovation work at home is complete I’ll be ordering a few more bits so I can achieve a good workout at home on days I can’t get to the gym.

Great as a small weight used for warmup.

Great as a small weight used for warmup, speedy delivery. Ordered with heavier weights and all turned up at the same time and within expected time frames. Easy to identify which weight is which with the coloured bands.

12kg kettlebell

Upgrading from vinyl to a cast irol kettlebell completely changed my workout —better grip and the compact sizing makes my movements smoother.
Very quick delivery.
Good value.

One for the future

Bought the 18kg kettlebell as something to aim for in the near future, 16kg first though!

Are cast iron kettlebells better than competition steel ?

Depends on what you're training for. Cast iron has a wider handle than steel competition kettlebells, better suited to two-handed swings and goblet work.

While steel kettlebells stay the same size regardless of weight, cast iron increments grow as you get stronger, this is what levelling up feels like.

If you want that classic, rugged feel with more room for your grip, these cast iron kbells are perfect.

Can I lose weight and build muscles using cast iron kettlebells?

Exercises with cast-iron kettlebells fire up your entire body, from your glutes to your core. Every swing and lunge burns fat and supports weight loss. With proper progressive overload and increasing your workout intensity, you can lose that weight and fat while building pure muscle.

How do I maintain cast iron kettlebells to stop them from rusting?

Cast iron kettlebells are finished with a durable coating that resists chipping and rust, but simple cleaning and maintenance can help extend their lifespan. After each strength training session, wipe down the kettlebell to remove sweat. This keeps the professional finish looking sharp and ready for the next use. Store them in a dry place or on a kettlebell stand or rack. Following these simple steps helps prevent rust in your gym equipment.

What kettlebell weight should I start with as a beginner?

For beginners, start with an 8kg to 12kg kettlebell for women or a 10kg to 16kg kettlebell for men. Your goal is to master the form and the basic. Then you slowly increase the weight in progressing. Choosing a weight in this range ensures you can move with the necessary speed and explosiveness without putting a strain on your muscles.

Cast iron kettlebell or vinyl: which is better for strength training?

For raw strength, cast iron kettlebells are better because their solid, compact build and textured grip are made for technical work and smashing personal bests. Meanwhile, vinyl kettlebells are designed for hybrid training, with a protective coating that makes them ideal for quieter workouts and floor-friendly use.
