Kettlebells are an amazing addition to your home gym, giving you the opportunity to lift heavy and add some conditioning work. You could actually build an entire strength and fitness routine around kettlebells. Press, push, pull, hinge, swing… kettlebells are so versatile (one reason that they’ve stood the test of time!)

But one traditional problem with kettlebells is that they take up so much space. Not always ideal for a small home gym. After all, every inch of floor space is precious when you want to kit out your perfect training space.

IronmasterUK Kettlebell Specifications

Ironmaster solved the problem with this truly innovative approach to kettlebells. You’ll wonder why nobody thought of this before!

The Ironmaster Quick-Lock Adjustable Kettlebell Handle is a really smart design from the home gym experts at Ironmaster. This system is the culmination of years of research and development, resulting in the most versatile and strongest adjustable kettlebell you can buy for your home gym.

See how it will save you tons of space (and cash) so you can continue to kit out your home gym space with no limitations.

“Built solid for functional heavy duty use/abuse and much more durable than you are. There’s nothing to break or fail and it only takes moments to change anything. Five stars for the Quick-Lock Dumbbells and Kettlebell that I actually own and consider priceless.” – Dwight

If you’ve already got the Ironmaster Quick-Lock Adjustable Dumbbells, you’ll already have an idea of how the Quick-Lock Adjustable Kettlebell works. It gives you all the benefits of a whole row of traditional kettlebells, with just one handle.

Home Gym Kettlebells Up To 80lbs

Here’s how it works. You get one handle, made from high quality steel for long-lasting strength and durability. Then you use our custom-made screw and weight plates to create a heavier home gym kettlebell according to your needs. The locking threads are made from top quality machined steel, so they will withstand decades of tough workouts. Changing the plates is quick and easy (no tools are needed), so it won’t hold you up even if you’re doing a kettlebell ladder or pyramid.

– Step by step images of weight changes –

We know that the feel of a kettlebell is really important. It needs to feel solid and comfortable in the palm of your hand whether you’re doing double-armed work or changing from hand to hand. Ironmaster Quick-Lock Adjustable Kettlebells feel exactly like traditional kettlebells – solid, robust, and comfortingly heavy.

This amazing kettlebell system has been used and reviewed highly by home gym kettlebell users from novices right through to competitive athletes. You’re going to love it as much as they do.

Adjustable Kettlebell System Saves Space In Your Home Gym

The Quick-Lock Adjustable Kettlebell handle itself weighs 22.5 lbs (10.2 kg) empty, which will be enough for some of you. But if you want to go heavier, the handle can accommodate plates taking it right up to 80 lbs (36 kg) with the add-on kit locking screws. With the standard locking screws, it will go up to 57.5 lbs (26 kg).

It takes the same weight plates as our Quick-Lock Dumbbell weight plates and uses the same locking screws which are heavy-duty, made of quality machined steel. So if you’ve already got the Ironmaster adjustable dumbbells, you won’t need anything extra once you’ve got the basic adjustable kettlebell handle. Just one more money saving solution from Ironmaster.

With the locking screw system, it locks up completely tight with no need for tools. You will feel totally confident as you swing, clean, and press this adjustable kettlebell.

Ironmaster have designed the handle ergonomically so it feels great for single handed work and is big enough for two handed work, too. We understand that you might want to do a huge range of exercises with just one kettlebell handle.

Why Choose This Adjustable Kettlebell System?

Quite simply, this innovative kettlebell handle and additional weight plates saves you space and cash when you’re kitting out your home gym. Kettlebells are a great addition to home training, but they will inevitably take up a lot of floor space. Ironmaster Quick-Lock Kettlebell solves that problem. All you need it one main handle, plus a set of weight plates which turn that one handle into as many kettlebells as you need. And the plates also work with our adjustable dumbbells, saving even more space in your gym and your budget.

Amazing Design

Everything about the kettlebell handle and locking system has been designed to make your life easier. You don’t need any tools to change, remove, or add plates on. It’s really fast and easy. And the handle itself feels great whether you’re doing single or two handed work.

“The handle is just the right shape and thickness for both of us. The way the weights are changed is very clever, simple and fast. Even with a lot of weight (well, a lot for us!) the kettlebell feels very secure and indestructible.” – Mr & Mrs H

Space Saver

This one kettlebell handle does away with the need to have a long row of kettlebells taking up floor space in your home gym. The weight plates are the same ones used for our adjustable dumbbells, so if you have both then that’s even more space freed up.

Cost Effective

Have you seen how much kettlebells cost? By replacing an entire set of kettlebells with one handle plus a set of plates, this system is friendly to your home gym budget. With the complete system, you get kettlebells ranging from 22.5 lbs (10.2 kg) to 80 lbs (36 kg) in 2.5lb (1.1 kg) increments. That’s a huge saving on space and cash!

Heavy Duty Kettle Bell

Kettlebells need to withstand hard work and serious workouts. They are the original serious training tool. Ironmaster’s Quick-Lock Kettlebell System is made from solid steel, and backed by a lifetime warranty.

“The Quick-Lock Kettlebell is a perfect addition to my home gym. It’s one solid piece of kit that should take the abuse I’m going to dish it! The Ironmaster is a quickly adjustable kettlebell that still has the same shape and feel of a standard kettlebell. I’ll definitely be ordering a second one!” – Derrick T.

Exercises to try with your Adjustable Kettlebell

IronmasterUK Quadriceps

Goblet Squat

Work your quads with this squat variation. Hold the kettlebell by the horns close to your chest while standing. Squat down, keeping your back straight and your chest and head up. When your hamstrings are on your calves, pause then return to the starting position.

IronmasterUK Hamstring Group

One-Arm Kettlebell Swing

This great compound move focusses on your hamstrings. Your starting position is with one kettlebell between your legs, your butt pushed back, knees bent and back straight. Looking straight ahead, swing the kettlebell forcefully between your legs. Quickly reverse direction and drive through with your hips, taking the kettlebell straight out in front of you. Repeat by letting the kettlebell swing back between your legs.

IronmasterUK Deltoid

One-Arm Kettlebell Push Press

Hit your shoulders by first cleaning the kettlebell to your shoulder. This will be your starting position with your palm facing forward. Keeping your torso upright, bend your knees to dip your body. Immediately reverse direction and drive through your heels to create momentum. At the same time, press the kettlebell overhead upward until your arm is fully extended. Lower the weight to the starting position and repeat.

And these are just a few suggestions!

What Can This Adjustable Kettlebell Handle Do?

There really is no limit with these adjustable kettlebells. Anything you could do with a traditional set of multiple kettlebells. Swing, clean, press, squat, lunge, farmer’s carry, overhead work… whatever your workout demands.

“The Kettlebell is an ancient Russian weapon against weakness” – Pavel Tsatsouline

So be strong and train with kettlebells.

Quick-Lock Kettlebell

8 reviews for Quick-Lock Adjustable Kettlebell Handle

  1. I’ve had this for 2 years now and still looks like it is new. This is the handle only which is 22.5 pounds. The grip with this one is way better than any other KB I’ve used. And I have to say that this one is more much better than the one from powerblock. In fact, the whole set (KB and dumbbells) is better than the ones from powerblock. You can add a lot of weight to it if you have the long screws they sell but honestly for the average joe this alone would do.

  2. Built solid for functional heavy duty use/abuse and much more durable than you are. There’s nothing to break or fail and it only takes moments to change anything. Somewhere down the road perhaps I may mist the plates with some rustoleum, but I treat iron like iron here. Five stars for the Quick-Lock Dumbbells and Kettlebell that I actually own and consider priceless. Couldn’t tell ya about Ironmaster’s other products aside from their fat grip adapters for the dumbbells that I also love and will never take off.

  3. If you are considering purchasing kettlebells, give this a look. The handle is well-made, with a wide, comfortable handle you can grip easily with both hands. The top is rounded, and tapers into the loadable plates to avoid irritation of your arms with overhead lifting. Locks up securely, so you can swing away without fear of launching a plate or two at a loved one. Just make sure the locking pin is snug before you hoist it. This is the handle only, if you do not already own Ironmaster plates and a locking pin, you will need to purchase those also. Weight ranges from 22.5 lbs with the handle alone, to 57.5 lbs fully-loaded. Purchase an extended locking pin and you can load the handle to 80 lbs. If you are into kettlebell training, and need more than 2-3 different weights, this is a great choice. I tried the Powerblock and Stamina versions of adjustable kb’s, and they just seemed more cumbersome and flimsy. After a month of regular use, I am still happy with the purchase.

  4. Both my wife and I have enjoyed using the Ironmaster Quicklock dumbbell for the past year. We wanted to buy a few other pieces of Ironmaster home gym equipment, so looked on the Valley Fitness website (it looks great BTW!). Whilst here, we thought we’d leave a review. The handle is just the right shape and thickness for both of us. The way the weights are changed is very cleaver, simple and fast. Even with a lot of weight (well, a lot for us!) the kettlebell fells very secure and indestructible – I do drop it from time to time. If you have any questions then email Valley Fitness – they are very good at getting back to you fast and they are honest and helpful.

  5. Bought one of these great adjustable kettlebells after seeing them in Muscle & Fitness magazine. I’d been looking at others, but they were either expensive or looked like they’d fall apart easily. I needed a kettlebell that I could change the weight quickly and I wanted it to feel like a normal kettlebell. These seem just right. I really can’t stress how good the build quality of this kettlebell is! I’m very happy and I know some of my friends will be purchasing one shortly :0)

  6. The Quick-Lock Kettlebell is a perfect addition to my home gym. It’s one solid piece of kit that should take the abuse I’m going to dish it! The Ironmaster is a quickly adjustable kettlebell that still has the same shape and feel of a standard kettlebell. I’ll definitely be ordering a second one! Valley Fitness were also a joy to deal with and their help and communication was faultless.

  7. I recently purchased the Quick-lock Dumbbells and Bench Combo – and thought I would also buy the Kettlebell handle to complement my training. I must say that the product is excellent. I have not really used a Kettlebell before – but after 3 workouts – i am very impressed. The fact that the weight is adjustable with the plates from the dumbbells is excellent. I am very happy with this purchase.

  8. I have just purchased two Ironmaster adjustable kettlebells; this is firstly the only company which stated,” that if I am not happy they would refund my money, no questions asked”. Secondly the quality, durability and ease of assembly of this product has amazed me and being an engineer, looking at mass production and profit margins you most definitely do get a bang for your buck. The reality is that product is expensive but compared to what else is available on the market and the long term durability, ironmaster is a no brainer. Please note this the first ever review I have written, and only because no other product I have used is worthy
