Dumbbells & Kettlebells
The industry’s best adjustable free weights! Got little time and space for working out? Our extremely compact and efficient dumbbells and kettlebells will give you the sculpted, stronger body you want, regardless of time and space constraints. Our adjustable dumbbells and kettlebells feature our patented Quick-Lock design that allows you to modify the weights easily and quickly. You only need a few seconds to increase the weight of our adjustable dumbbells from 5lbs up to 165lbs. The same holds true for our adjustable kettlebells that can hold anywhere from 22.5lbs to 80lbs using the same weight plates and screws as our dumbbells. Take note that the weight capacity of our adjustable dumbbells and kettlebells will also depend on the type of locking screws you will use. For our next lottery drawing info, please click here.

Our quick-lock adjustable dumbbells can be adjusted from 5lbs to 75lbs in under 15 seconds. So if you think you need to devote hours for your workout, our adjustable free weights will prove otherwise.
Our fixed-weight rubber dumbbells are even quicker to use and promote an efficient training experience with their highly visible weight markings and compact square shape.
Space-saving fitness gear
Aside from saving you time, they also save you plenty of floor space. Our adjustable dumbbell handles measure only 6.7" square and 14.5" long with the 75lb weight plates. On the other hand, our empty kettlebell handle is only 8.75" wide and 7.75" tall. As you can imagine, they only take up a fraction of the space required by a rack of fixed dumbbells or kettlebells.
This is why so many people with limited floor space find our equipment the perfect addition to their home gym.
However, if you prefer training with fixed weight dumbbells, we suggest you check out our 3-tier and 4-tier dumbbell racks. These multi-level racks will save you space, keep your dumbbells organized and off the floor, lowering your (and your kids’) risk of tripping over them.
Our adjustable dumbbells and adjustable kettlebells are designed to adapt to your evolving fitness level and capacity. For our adjustable dumbbells, we offer a 45lb set suited for beginners, a 75lb upgrade kit for experienced trainers, and a 120lb and custom 165lb Add on weight kit for advanced trainers. We also offer weight kits of 57.5lbs and 80lbs for our adjustable kettlebells. As you progress in your dumbbell and kettlebell training, you can easily adjust the weight of your equipment to match your current level of strength. Our fixed weight dumbbells are available from 5 to 100lbs to cater to a wide range of trainers as well.
Easy to use
Easy and quick weight changes - this is the promise we have been fulfilling since we created our adjustable dumbbells and kettlebell systems. The shape of our specially designed plates allows them to simply stack together and lean toward the handle, making the process of changing them easier for you. True to its name, our Quick-Lock design lets you add or remove weight plates with ease. Just turn the locking screws and adjust the weight to your liking! If you’re using these weight plates on your EZ Curl Bar or Straight Bar, simply load the plates and secure them in place with the fast-acting spinning collars.
The user-friendly design of our dumbbells and kettlebells is one of their best-selling points. From the comfortable, wide handle of our Quick-Lock adjustable kettlebell to the knurling on our EZ Curl Bar, you can expect a superior level of comfort from any of our dumbbell and kettlebell products. Our adjustable dumbbells even offer no restrictions in terms of how you can grip them.
Borne out of extensive research and development, our adjustable kettlebells, in particular, are very popular among trainers. Their handle feels like that of their traditional counterparts, and the locking screw doesn’t interfere with your grip. Lastly, the adjustable weight plates are labeled in both lbs and kgs for your convenience.
High level of functionality
If you’re looking for cost-effective and powerful fitness tools, consider our adjustable dumbbells and kettlebells. Their weight plates and locking screws can be used interchangeably. The same weight plates can also be used on our EZ Curl Bar and Straight Bar.
Our adjustable dumbbell stand is also designed to hold the 120lb Add on Kit while supporting your adjustable dumbbells. Aside from providing an extra challenge to your workout, our fat grip adapter set is also suited for use with the IM2000 lifting bar.
Superior safety features
Our adjustable dumbbells and kettlebells are safe to use in all types of training. Excellent construction and well-thought-out design result in a safe and sturdy piece of equipment that will last you for years. Everything locks up tight and can only be released if the locking screw is unscrewed and dialed to exactly 12 o’clock. No plastic or fragile parts are used to assure reliability.
Our adjustable dumbbells and kettlebells are known for being safe and secure. Once you have made sure that the locking pin has a snug fit, we guarantee you that there will be no rattling plates or injury risks with our products.
Durability you can rely on
We only use the highest quality materials for our dumbbells so you can rest assured they will withstand years of use and abuse. Made with chrome plated steel handles and solid cast iron plates, they have no breakable or plastic parts and come with a lifetime warranty.
Our equally heavy-duty adjustable kettlebells also contain no breakable parts and our EZ Curl Bar and Straight Bar are made of solid, chrome plated steel. Even our dumbbell racks and fixed dumbbell weights feature the same level of durability as our adjustable dumbbells and kettlebells.
Our fixed dumbbells also offer great convenience for trainers. Simply grab the weights you need and start lifting! These fixed weights also perfectly complement your other Ironmaster Gym equipment including Quick-Lock dumbbells. If you are training with a partner or a group, having this set of fixed dumbbells will help ensure every trainer has a dumbbell for their workout.
Classy modern style
Our adjustable dumbbells, kettlebells, and even our fixed weight rubber dumbbells have a stylish look that will enhance any gym. These products come in our signature square shape. Our fixed dumbbells also feature our custom Ironmaster logo design.
