REP Fitness Rubber Hex Dumbbells Review

The REP Fitness Rubber Hex Dumbbells are super reliable — they’re nothing fancy, but can offer weights ranging from 2.5 pounds on the low end to 125 pounds on the higher end, so you won’t be limited in how you can train. If you could choose just one piece of equipment in your home gym, we would argue that you should go all in with dumbbells. Lighter dumbbells can be used for pilates work and high-rep HIIT workouts, and, if you can afford them, heavy dumbbells can help facilitate strength gains and muscle growth. Most of the things you can do with a barbell, you can do with a dumbbell, so don’t be fooled into thinking they’re a weak training tool. 

Though these pairs may seem pricey, you’re getting a high-quality pair of dumbbells that will likely last you a lifetime. From the ability to perform curls and chest presses to goblet squats and Romanian deadlifts, dumbbells are some of the most versatile pieces of equipment you can have in your home gym. If you’re looking to build out your gym with lasting, hexagon-shaped dumbbells with straight, fully knurled handles, these REP Fitness Rubber Hex Dumbbells are worth the investment.

The REP Fitness Rubber Hex Dumbbells range in weight from 2.5 pounds to 125 pounds. You can buy them in pairs, and they have a knurled handle for grip, as well as a hexagon shape for stability on the floor. 

REP Fitness Rubber Hex Dumbbells Highlights

There’s no way around it — if you’re buying multiple sets of dumbbells (especially the heavier pairs), the costs can add up. These pairs range in cost from around $15 to over $500, increasing as the weight gets higher — this is right on par with Rogue’s other dumbbells, but you can find some cheaper, more generic options on the market. With these, you can buy pairs as low as 2.5 pounds and as high as 125 pounds.

The dumbbells have a hexagon shape to prevent rolling, and are coated in rubber so as not to damage any floors — plus, the rubber is also low-odor, which is ideal for home use. One pair of dumbbells is not going to take up a lot of space, but if you’re buying multiple pairs, they will take up a decent of room in your home gym, so you will need to ensure you have the space for the number of pairs you’re buying. Otherwise you will be better off opting for an adjustable dumbbell or just one or two sets of dumbbells you can store more easily.

Who Should Buy the REP Fitness Rubber Hex Dumbbells 

  • Anyone who wants multiple weights of the same build to choose from will appreciate that these pairs range from 2.5 pounds to 125 pounds. 
  • Folks who want rubber coated dumbbells to protect the floors of their home gym. 
  • Lifters who like that hexagonal dumbbells don’t roll around on the floor. The stability of hex dumbbells allow lifters to perform movements, such as renegade rows and push-ups, without the risk of face-planting. 

Who Shouldn’t Buy the REP Fitness Rubber Hex Dumbbells 

  • Buyers on a budget will be better off searching for cheaper pairs. You’ll be paying for the high-quality build here, but you can definitely find less expensive options out there at all weights — though they may be from more generic or lesser-known brands.
  • If you’re generally short on space — maybe you live in an apartment or your living room doubles as your workout area — you may be better off snagging a pair of adjustable dumbbells to save space.


These weights range from around $15 to over $500 — the price increases as the weight increases, so the heavier you go, the more expensive the pair. And this does not include the rack(s) you might want to store your weights, which will cost you an additional $180 a piece — though if you’re just buying one or two pairs, a rack may not be necessary.

Overall Build and Quality

The REP Fitness Rubber Hex Dumbbells range in weight from 2.5 pounds to 125 pounds. They have a rubber coating to protect any surfaces in your home, and fully knurled handles to offer maximum grip. Plus, they’re all the same design, which can help give your home gym a cohesive feel if you are buying multiple pairs.


These pairs come in multiple weights, with the lightest weight being 2.5 pounds and the heaviest being 125 pounds. All of the dumbbells offer fully knurled handles and low-order rubber coatings, as well as easy-to-view numbering on the top of each weight, so you can easily switch out weights mid-workout. Below, we dive a little deeper into these features.

Weight Options

These dumbbells are sold in pairs, and the weights range from 2.5 pounds at the lightest to 125 pounds at the heaviest. They increase in increments of 2.5 pounds or five pounds as you get higher in weight, which means you can choose from 31 different pairs of weights. 

Handle Grip

The handles on all of these dumbbells are fully knurled, which means they have small ridges that can help provide solid grip. They also vary in width based on weight, ranging from 22 millimeters (mm) to 34mm as the weights get heavier. The thicker handle is meant to add more comfort to your grip with the heavier weights. However, they are straight rather than ergonomically shaped, which some may like, while others may want more of a contour. 

Weight Design

These dumbbells have a classically common look to them. The heads on either end of each dumbbell are a hexagon shape to allow them to sit flat on a rack or the floor, and each iron weight is coated in rubber to protect the surfaces in your home. You’ll also find numbering that is easily visible on the top of each weight, which makes switching weights mid-workout seamless. Plus, these weights all look the same, varying only in size, which can make for a cohesive look within your gym space if you opt to buy multiple pairs.

Product Specs 

The rubber used to coat the dumbbell heads is low-odor, so you won’t have to wait for them to air out before you can stow them in your home gym. If you opt to buy multiple pairs, they will take up a fair amount of space though, so you’ll need to ensure your home gym has the room for a rack of dumbbells — or multiple racks depending on how many pairs/racks you purchase. But, it’s worth noting that you will have to purchase those racks separately as they do not come with these dumbbells. 


The heads of these dumbbells are attached via friction welding, which means these weights are all durable enough to last a lifetime. The weights themselves are made of iron, while the heads are coated in a protective layer of low-odor rubber. And the metal handles are knurled for grip and comfort, though the handles are not ergonomically shaped like others sometimes are.


While each pair of dumbbells is fairly portable on its own, it may be difficult to do a lot of back-and-forth moving of multiple pairs of dumbbells. Plus, as the weights get heavier, you’re less likely to be able to move them long distances. A supplemental rack can help provide a designated place for your weights, so you don’t have to dig through a pile of dumbbells to find the pair you’re looking for.

Size and Dimensions

A pair of dumbbells on its own is not going to take up a ton of room — maybe just that of a single shoebox. But if you’re buying multiple pairs to fill out a home gym, you could end up needing room for five or 20+ pairs of dumbbells. And the heavier bells take up even more room on their own. This could equal out to a ton of floor space, or at least one rack of dumbbells (or two or more for more extensive sets).


These sets do not come with a rack. If you want a designated rack to store multiple weights, it will cost you an additional $180 per rack. Or, if you don’t have that many pairs, you can just buy a storage tray, which will shave about $100 off that cost. While you can just stack your dumbbells on the floor, a supplemental rack or tray can provide more organization in your gym space. 


REP Fitness offers a one-year warranty on these dumbbells for commercial use, and a lifetime warranty for home use.

Final Word

The REP Fitness Rubber Hex Dumbbells offer a wide range of weights — from 2.5 pounds up to 125 pounds. If you are just starting to build out your home gym from scratch, buying multiple pairs of these can be a great option for you. Or if you just need one or two pairs, rest assured that these ones are built to last a lifetime. Plus, they have knurled handles for grip, and a rubber coating on the heads to protect your floor.

It’s worth noting that if you do decide to purchase multiple pairs of these dumbbells, they can take up quite a bit of space, and are a big investment. But if you’re a committed fitness enthusiast and know you will make use of them, the REP Fitness Rubber Hex Dumbbells are reliable and likely the only bells you will ever need to buy. 


How much space do I need for the REP Fitness Rubber Hex Dumbbells?

If you just buy one or two pairs, not that much space — maybe the same amount of space it would take to store a couple pairs of shoes. If you choose to buy more than a couple pairs, they can take up a decent amount of space. You could need room for anywhere from five to 30 sets of dumbbells, all of which will range in size depending on weight. If you rack your dumbbells, this may equate to one to 2+ racks.

Are the REP Fitness Rubber Hex Dumbbells expensive?

In short, yes. Even the lightest pair is more expensive than the market average, and the heaviest pair will cost you over $500. However, you’re getting dumbbells that will likely last you a lifetime, so it can be worth your money, as long as you make use of them.

What weights do the REP Fitness Rubber Hex Dumbbell come in?

These dumbbells are sold in 31 different pairs with weights ranging from 2.5 pounds to 125 pounds. They increase in increments of 2.5 or five pounds as they get heavier.
