    Size chart

    Train heavy with adjustable dumbbells that feel compact and solid like fixed dumbbells. The Ironmaster Quick-Lock Adjustable Dumbbell Set (2 x 34 kg) combines fast weight changes, an all-metal construction and two dumbbells that are each adjustable up to 34 kg.

    Benefits of the Ironmaster Quick-Lock Adjustable Dumbbell Set (2 x 34 kg):
    ✓ Set of 2 adjustable dumbbells, each adjustable from 2.3 to 34 kg
    ✓ Replaces 2 x 15 fixed dumbbells in one compact set
    ✓ Patented Quick-Lock system for fast weight changes
    ✓ All-metal construction without fragile plastic parts
    ✓ Flat ends and fine knurling for comfort, balance and a secure grip

    Fast weight changes with the Quick-Lock system
    The patented Ironmaster Quick-Lock system makes changing weight quick and secure. With a short twist, you unlock the Quick-Lock locking screw, remove or add weight plates and lock the dumbbell again. This lets you adjust the weight within seconds, without complicated click mechanisms or vulnerable plastic parts.

    The feel of a fixed dumbbell
    Many adjustable dumbbells feel bulky, long or unstable. Ironmaster Quick-Lock Dumbbells stay compact and well balanced, even when you train with less weight. The flat ends rest comfortably on your thighs when starting heavy presses, while the fine knurling on the handle provides reliable grip during rows, curls, shoulder presses and other strength exercises.

    Built for serious strength training at home
    This set is made for strength athletes who want to train heavy in their home gym without a full dumbbell rack. The fully welded iron and steel construction feels solid and is designed for intensive use. No fragile plastic housing, no surrounding cage design, but a robust adjustable dumbbell system that stays close to the feel of traditional dumbbells.

    Space-saving and expandable
    With this set, you replace 30 individual dumbbells with one compact solution. Each dumbbell is adjustable from 2.3 to 34 kg and can be expanded with optional Ironmaster expansion kits to 54 kg and even 74 kg per dumbbell. Ideal if you want to keep building strength while keeping your training space clean and organized.

    Exactly what I wanted, quick to change weights by adjustable dumbbell standards, and it actually feels like a dumbbell. Stable, no rattling, great grip 👍

    Manubri indistruttibili, ben bilanciati, possono raggiungere carichi davvero alti e nessuna paura di romperli. Zigrinatura perfetta e meccanismo di blocco ottimo! Appoggiarli sulla pancia o sulle gambe per iniziare o finire l'esercizio è comodissimo a causa della forma quadrata e raccordata dei manubri e alla forma piatta alle estremità. Ho frequentato diverse palestre negli anni, ma questi manubri battono anche tutti quelli commerciali che ho utilizzato fino ad ora. Il prezzo non è basso, ma una volta provati valgono ogni singolo centesimo! Personalmente li utilizzo con upgrade a 54kg a manubrio.

    High Quality Dumbbells

    The ironmaster adjustable dumbbells are fantastic. They are all metal which really makes them feel durable compared to others with lots of plastic components. All dumbbells pieces and weights were shipped with proper protection so everything arrived in good condition (surprising how many expensive companies don't protect their shipped product).

    Only had the dumbbells for a month so far, but they have worked great. Really like the fact that they feel like regular dumbbells and it feels normal to do dumbbells exercises with them. Will update review if anything changes my opinion as I use them over the coming months to years.

    Better Then Expected

    I was considering a lot of different adjustable dumbbells before getting these. Many of then used plastics, internal gears that could give out, docking stations that are required just to adjust weight, and many more complicated and silly designs. But these were simple and had the normal dumbbell feel.
    I like that the construction is all metal material, and I don't have to worry about parts breaking because of a drop (haven't dropped them yet, I'm confident they'll be fine). Some videos I have seen talk about it being slower to change weights, but its not slow at all. I keep my plates organized so changing plates is quick and the pin design makes it even easier to remove or add plates. Also, the flat bottom is very comfortable when you got to rest it on your thighs.
    Makes my garage gym complete.

    Just what the doctor ordered

    Like many others I spent a lot of time reviewing adjustable dumbbell sets. And in the end, I'm really happy with the purchase. My Ironmaster dumbbells are high quality, easy to use, requires minimal storage space, and the 75lb set is the enough weight for almost all of my endeavors. These are the perfect adjustable dumbbells for any garage gym.

    75lb adjustable DB set

    First off, these things are built tough. The knurled handles feel comfortable in your hands and honestly these feel just as good as real DB’s. I also got the 120lb extension kit to go along with them. Best purchase I’ve made in a long time.

    Fantastic Equipment

    These dumbbells feel great and get the job done! So far the quality seems excellent. I wish I had bought a set sooner! Will be buying the 120lb extension set when the time comes. Worth every cent

    Hot Gear

    Just got my dumbbells the other day and I'm very pleased. I live in Phoenix, so I need equipment that can handle the heat. These should do very well, no plastic! easy to use and definitely worth the money!

    Exactly what I was looking for

    I wanted adjustable dumbbells so they didn’t take up a ton of space: did lots of research and I’m thrilled with them. They are made to last. No plastic parts that might break or overly complicated bells and whistles - just solid, well-designed engineering. Love that they are square so you can put them down and have them stay put. Worth the investment as I know we’ll have them for years and years.

    Awesome Dumbbells

    These dumbbells are my first my real piece of home gym equipment and I cannot recommend them enough. It's incredibly easy to adjust the weight, the knurling feels great, and they actually feel like dumbbells when used during various exercises.

    Great Start

    These are my first weights that I've ever owned and to say I'm satisfied is an understatement. These are worth the price from the material being real iron; To the paint and design; and to the ease of use. The price of these weights is more than fair for what you get and I can already tell they will last for a long time. Not to mention all the add ons you can get insetad of having to search for other options. As I grow in my journey I will definitely be brand loyal to Ironmaster.

    Adjustable dumbbells

    I don't typically write a review. But this is a big purchase. It is well worth it. These dumbells feel better than any standard dumbbells I've ever used, and the square shape prevent rolling around.
    The knurling is very comfortable and does it's job.
    Thinking of eventually purchasing the extra 45lb per dumbell.
    I would highly recommend these for a home gym. All metal components, made to be abused, ha!

    Adjustable 75lb dumbbells--Best purchase in my home gym

    I have a newly set up home gym that is well supplied. This dumbbell set is an important part of it and is the highest quality item in the room. These are so much better than competitor plastic dumbbells and/or weird shapes that make them hard to lift.
    These however are perfect. And extremely high attention to detail--even the minor installation is easy because everything fits as it should and is durable. They feel great and are easy to change weights plates.
    Plus you can upgrade further AND get a kettlebell attachment? Cmon--perfect! Great work Ironmaster!

    Quick, compact and stellar quality

    I had a set of Bowflex adjustables and wanted to upgrade to the larger size, but I figured I'd check out some alternatives — I'm glad I did. After reading a lot of reviews (Garage Gym Reviews has some helpful stuff) I landed on these Ironmasters because of their quality and durability. Don't be concerned about the speed of changing weights. It's about 30 seconds to change both dumbbells. I love how solid these feel — and they look amazing.
    I ended up ordering the heavy handles, which I'm keeping, and another accessory, which I decided to return. The return process isn't complete but has gone smoothly so far. Great customer service. I hope to get strong enough to need the next weight expansion so I can get more of their stuff.

    High quality and expandable
    I have a home gym and was looking for a good set of dumbbells. Most of the dial ones don't go high enough. These are expandable, I bought he 120lb add on also. They are easy to adjust and are very high quality. The iron plates are cast so finely that they almost look fake. Usually iron plates look rough but not these. The weights fit together perfectly and the handles are beefy and comfortable to hold. They handle just like gym dumbbells. Very happy, these are awesome!

    I compared and debated making this purchase forever it feels. As a person who likes to lift heavier dumbbells, THESE are by far the best selection for the money. No regrets and would happily buy them again without question.

    Great Product
    My first set of adjustable dumbbells. Needed to go beyond my static set to have higher weights. No regrets. These are incredibly solid to hold and easy to adjust. I also bought the kettlebell and it is great to be able to interchangeably use the weights. I went all in with the Pro Stand (it was Black Friday). The whole set is very well thought out and will last for a generation or two. I say this from experience. I purchased the IM1000 in the year 2000 and it still looks brand new.

    QLADBs
    1- sturdy 2- quick changing or adding plates basically takes little time as in 20-30 seconds a DB. 3- Quick Lock screws are legit and lock in tight no worries bout these screw locks coming out. 4- feel like fixed DBs, they just feel so good lifting. No cheap plastic no rattling. 5- drop them and don’t worry, I don’t really drop mine but I have a few times with heavier weight due to my bad back I prefer to just drop the weight if my back ain’t feeling right and they hold up with zero issues. I can see how anyone would pass on these. Best Adjustable DBs ever made. I wish I got these years ago.

    These are fantastic
    I got these and the add on kit to create 120lb dumbells for my home gym. These are fantastic dumbells. The grip resembles the knurling of a power bar. They are nice and compact and pretty easy to adjust. They save you a lot of space and money compared to a full out dumbell rack. I would say these are the best adjustable dumbells on the market. The only thing to test is how long they hold up and last. I am assuming that will be a long time as they seem very high quality. Big fan

    Love these from day one
    Bought these for an update from NordicTrack dumbbells. Though changing weight is a bit harder, I really like the sturdy design of iron master. The longer holding bar needs some getting used to, but overall it has actually is more compact than NordicTrack. Also it gives me the freedom to increase the weight to 95lb. FREEDOM!!!

    Best dumbbells for home gym
    I finally pulled the trigger on purchasing a home gym setup but have limited space in a 2 car garage. These are by far the best adjustable dumbbells on the market, especially if you’re trying to save space. The quality of these is amazing. Don’t have to worry about something breaking if you drop them like almost all other adjustable dumbbells. I also really appreciate the first responder discount. Communications were fast and easy to verify eligibility. Will definitely be buying more from iron master!
