Our adjustable dumbbells look, feel, and function just like real dumbbells. They are solid and ready to go containing no plastic or fragile components. More information about this product is available in the product details section.

    Includes 1 pair (2) of 75 lb adjustable dumbbells.

    Outstanding Product
    ROnak Mukhopadhyay (GA) | January 18th, 2023
    Perfect product for those who value quality & invest in their fitness / health. These have a great feel that mimics traditional DBs. The quick-lock is secure and I have no concerns about equipment failure during the middle of difficult sets. They also fit in my very small footprint home gym, and are invaluable for providing much needed exercise variety. Simply fantastic, and looking forward to getting strong enough to need the heavier expansion!

    The best adjustable dumbbells
    Ryan (Hercules, CA) | January 15th, 2023
    I bought these after debating whether to buy the twist-adjust DBs that adjust instantly and I'm very happy with my decision. These DBs feel like you're lifting a solid piece of metal because there's no movement whatsoever between the plates. There's a lifetime guarantee but I'm not worried at all that these will break.

    Changing the plates is fast but not instant. The only thing you can't do is a drop set. However, you can combine these with other equipment to do a super set. Rest assured though that you can easily change the weights in time between traditional sets.

    The "plate math" is super simple and there's plenty of room on the PRO stand to keep all of the weights that come in this set (2 stacks of 5 lb plates and 1 stack of 2.5 lb plates). You can also increment the weight by 2.5 lbs by adding an extra 2.5 lb. plate to one side (twist-adjust DBs increment by 5 lbs).

    I highly recommend the heavy plate handle kit to improve the balance. It makes the lightest weight 20 lbs but because it improves the feel, I think it's worth it to get it and buy 15 lb. DBs if you need them.

    These are the best adjustable DBs you can buy. They can expand to more weight than you can ever lift and you'll feel like you're pumping iron instead of a toy or gadget.

    Compact and Heavy
    Scottie Tudor (Houston, TX) | January 12th, 2023
    These dumbbells are beasts. The quicklock system is much more stable than camlock style dumbbells and the plate design makes for a very compact package. While they tend to get long as they get heavier, that length isn't a hindrance as it allows the weights to be slim, giving a better range of motion than variable dumbbells using larger plates.

    Great set of dumbbells
    Hal (Florida) | December 31st, 2022
    After doing extensive research on various adjustable dumbbells, I zeroed in on Ironmaster’s quick lock set. I just received them a few weeks ago and they are great! Very rugged and well made. Should last a lot longer than their plastic competitors. I also ordered the curl bar that works with the dumbbells’ weight plates. Overall, I’m very satisfied with everything!

    fantastic equipment
    henry goldbeck (British Columbia) | December 28th, 2022
    My son and I purchased the dumbbell set a month ago and are extremely pleased with it. The design, quality and functionality are fantastic. We bought direct from the showroom in Monroe WA and were excited to see some of the other Ironmaster equipment especially the multifunctional benches which have the same positive qualities. We have added them to our home gym wish list.

    Best piece of gear in its category Ive ever used
    Chad Pietsch (Lexington Virginia) | December 13th, 2022
    Having been a precision machinist for over a decade I can say these are one of the highest quality designs Ive ever seen. They lock so tight its amazing. They proprietary locking shaft is ingenious. They have replaced countless pairs of fixed DB’s. If you are looking for an investment thats well worth the money, these live up to the hype and then some! These are solid!

    In love… Just Wow
    Reece | December 7th, 2022
    I didn’t realize I could love a piece of equipment so much. The dumbbells with stand look great in the home gym, and I’m extremely impressed with the build quality. They are absolutely bombproof and I’ve got no worries that these will last a life time. Shipping was quick once they were in stock, and to be honest it was also some of the best packaging of equipment I’ve ever received. In total it came in 6 boxes, each plate individually wrapped, all items could survive a nuclear winter. I would recommend these to anyone looking for an adjustable dumbbell and after using all of the other “competition” in the past I’m absolutely sure the Ironmasters are the clear winner.

    Just bite the bullet and buy these and the expansion set
    Daniel (Ohio) | October 28th, 2022
    I'd been looking at these for awhile. Bought the Super bench and a bunch of the exercises so I know ironmaster is good, but these are pricey and hard to find in stock. Finally bit the bullet and bought them when they were in stock. All Ironmaster stuff is good, but these things are even a step up from their normal stuff. The dumbells look like a work of art. More importantly they work great and I've already worked up to using 80's on incline bench. Highly recommend the dumbell spotter as well. Without it I don't think I could lift nearly as much.

    Best adjustable dumbbell I've used
    Brandon (Texas) | October 28th, 2022
    First impression of these dumbbells are very good quality as they all arrived miraculously No damage to any of the shipping boxes everything was well packaged. In comparison I've actually owned the power block Pro DBs 90lb and yes even though They are more efficient when it comes to adjusting the weights due to the box type design aka cage They just feel unnatural compared to ironmaster. If you're considering these vs power blocks I definitely have to say Ironmaster for the win most people rest anywhere from 60 - 90 seconds which is plenty time to change the weights on these dumbbells. The knurling on the handle feels good not super aggressive but not passive either. I've also had the opportunity to utilize Nuobells And I would still choose ironmaster over them as they just don't feel like commercial dumbbells. When you use ironmaster It just feels like a real commercial gym dumbbell It does not feel awkward at all. Overall I'm very impressed with my purchase and have no regrets definitely worth the money you won't regret it.

    Best Decision
    Harold (California) | October 26th, 2022
    I have a dumbbell set up to 50lbs and quickly needed heavier dumbbells. With DB sets from 55-100lb pairs ranging up to almost 3k and the thought of how much room it would take in my garage...this was a no-brainer. Easy to add and remove weights, and I have tye add on that let's it get to 120lbs. Very small profile and a lot of versatility. Perfect solution

    Worth every penny!
    John (UT) | October 2nd, 2022
    I'm impressed with the solidity of the dumbells even at 120 lbs. I am very grateful for the excellent engineering. They are a TON cheaper than buying heavy dumbells individually and save a TON of space. Switching the weight is like counting how many dollars I have saved with this purchased. Nicely done!

    Quick Lock 75 Lb Adjustable
    Nathan (Maryland) | October 1st, 2022
    I recently bit the bullet and purchased the 75# adjustable dumbbell set. This is my first set of adjustable dumbbells and I did a ton of research. For me, I already had existing smaller dumbbells (in the 10-35# range), so was drawn to Iron Master set for two prime reasons: durability and accommodating heavy loads. Most adjustable dumbbells in this price range have plastic internals for the interlocking mechanisms. While quicker, I expect they are far less durable and most certainly don't advertise that you can drop them; in fact, most tell you not to.

    I've had them now for a few weeks, and though I haven't really pushed it to the limits and dropped them from several feet, they definitely feel durable. So far, so good.

    Granted, I'm only a few weeks in, but so far my impression is that I would recommend them to anyone looking for a rugged, long-lasting dumbbell to add to their home gym.

    Expensive, but worth it. Love the quick adjust and solid feel. The only person unhappy with my purchase was the UPS guy who had to deliver them!
    Buy Once, Cry Once
    Larry (Raleigh NC) | September 23rd, 2022
    Back when gyms closed due to Covid, we all scrambled to set up home gyms. New companies sprang up with no track record. The demand for established products like the Ironmaster dumbbells were insane. After about 3 months of trying I finally was able to order. They were everything I assumed. No plastic parts to break and shaped like traditional DBs. They aren't cheap but compared to any other adjustables, they're worth every dime if you want something that will outlive you.
    I'm loving these!
    Aleksandar (Algonquin, IL) | August 22nd, 2022
    After watching and reading tons of reviews I settled with these Ironmaster adjustable dumbbells. I liked Powerblocks as well, but Ironmaster won out for durability incase of drops, and more natural feel. Even as you add plates, they never feel too long or big in relation to a regular dumbbell of the same weight. The other adjustables didn't feel as nice. I also added the heavy handle kit at the same time I bought these and it really gives the handle grip a nicer feel by shortening the handle length. They feel great! I notice no difference between these or regular dumbbells. I'm still working on adjusting the plates faster, but the system works great. No rattles, no plate movement (they fit very tightly), and a natural feel. The stand was smaller than I expected, but it works and the positive is it takes up very little space. Compared to the space a traditional set would occupy, the footprint on these is nothing! You won't regret getting this setup!

    Quick-Lock Adjustable Dumbbell System 75lb Set
    Jason (Brooklyn NY) | August 12th, 2022
    Scarce: Yes, they took forever - to be available. I have been trying to buy these since the Pandemic began. Pricey: Are they? If you buy individual weights, to 75lbs - not really. Quality and Ease of use: Priceless and Spot-On. I would wait again and again for the quality that came with this. Most adjustable weight are flimsy, and “Shakey”, at best; these are SOLID. Highly recommended. Spend the money, this is worth it. I’m waiting on the Add-On, to get to 120lbs.

    Exactly What I wanted
    John (IL) | August 4th, 2022
    I was looking for a high quality and strong adjustable dumbbell set. After using other brands that had plastic components, I was happy to find Ironmaster. Everything is steel and very strong. I like the aesthetics and the design a lot. The only detraction I commonly see is that it takes time to adjust the dumbbells. This doesn’t bother me at all because I lift heavy 90% of the time. I’m in no hurry to change the weight plates for a 70lbs dumbbell press. As soon as the expansion kit is back in stock, I will be purchasing that immediately.
    Amazing, worth every penny
    Jacob Gonzalez (Upland, CA) | August 3rd, 2022
    This is my first time buying gym equipment after deciding to make my own gym at home, these are easily the best investment in my health and fitness journey I have made and will probably ever make. Unfortunately if you are someone who needs to do supersets with different weights, they are not super fast to change weight (considering you have to do all 4 sides) which is not a problem for me at all because I am a slow lifter. Still worth every penny regardless if that's a problem for you or not, I can't give anything less than 5/5

    Rock Solid and Quick Changing
    Sterling Brown (New York) | August 3rd, 2022
    I've been using the Ironmaster adjustable dumbbells for around a month now, and I've been really pleased with their performance. After a lot of research, I decided to get these vs the Nuobells, Powerblocks, Bowflexs, and Pepins. I love how these use absolutely no plastic, and because of the square ends of the weights, they're extremely easy to add or remove weight from with the quick lock system. Even though some competitors can be slightly faster, knowing that these aren't fragile and won't break after being dropped is a huge peace of mind. Swapping weights only takes around 30 seconds, which is the perfect weight time between sets.

    I'll probably be getting the heavy handle kit in a few months, but for my current level, these are a great range of weights.

    Unique design
    Marc Brunton (California) | July 18th, 2022
    If I saw this product in a sporting goods store I might look at it twice. It is a unique design, plates change quickly, the lock bolt is easy to operate. I like the sturdy cabinet that is easy to assemble. The plates are heavy duty, The only real negative is the price. It's a great product but expensive.

    Extremely High Quality Dumbbell Set
    John | July 13th, 2022
    This is a great set of dumbbells, they are secure, heavy duty, easy to adjust, and have the same feel as traditional non-adjustable dumbbells.

    I wish I discovered these before I found the Powerblocks, it is nice to finally have a reliable dumbbell set that does not use fragile and flimsy parts, unlike Powerblock. My set of Powerblocks became unsafe and nearly unusable with all the parts that kept chipping away and snapping off.

    I am absolutely impressed with the high quality of this product, and the way it was so carefully shipped really caught my attention and showed that this is a company that cares and stands behind its product. Thank you Iron Master!

    Heavy (pun intended) duty
    Kevin | July 11th, 2022
    The very first thing you notice is the quality of materials used. Everything is clean, undamaged (very well packed), and clearly durable (chrome plating looks of high quality with powder coated weights). I haven't really banged em around much yet but I'm hoping I'm right when I say that I can see these withstanding the test of time and frequent use. Other products may change weight faster (comparable to changing weights on a barbell, with only 5lb plates available), but not with the availability of the additional weight (of the add-ons) my only complaint is that the pack of hardware to assemble the stand was missing the screws for the top platform but ironmaster was quick to respond to my email and send some out. Great customer service and quality product.

    Excellent quality and shipped/packaged well
    Kp (Texas) | June 30th, 2022
    I began my search for adjustable dumbbells with a similarly priced competitive "selectable" dumbbell product - both dumbbells arrived broken on my doorstep. They were not packaged well and their customer service was disappointingly subpar. I could never imagine hoisting those 80lb "selectable" dumbbells with plastic parts above my head after seeing how easily they broke in transit.

    In contrast, the Ironmaster dumbbells were packaged very well and all parts of my order (dumbbells, stand, kettlebell) arrived in absolutely perfect condition (same carrier as before). This kind of attention to detail from Ironmaster truly communicates what kind of company they are!

    I am very impressed with the build quality of the dumbbells, plates, stand, and kettlebell (and I'm very picky about these things). Everything works exactly as advertised. While it takes a few moments longer to change plates, I find the process to be totally reasonable between sets. The tradeoff for having super solid (no movement) and reliable dumbbells is definitely worth it, and I feel very safe using this product.

    Well done, Ironmaster. Thanks for doing things the right way.
    Well built product
    Eric Albrecht (Oshkosh, wi) | June 24th, 2022
    Very well built and easy to use. I love using these things, very compact too. I think they are easier to hang onto than even a regular dumbell. It's so nice to have 5 to 75lbs adjustable dumbells. They change out fairly quick. These are one of my better purchases.

    Long Term Review
    Van (CA) | April 6th, 2022
    I've been using these, along with the additional weight kit, for over 15 years and they are still working great. I mostly only use them for heavy sets. I've supplemented them with quick select dumbbells for speed. If I could only have one set, it would be these.
