The Best Adjustable Dumbbells for Your Home Gym
Adjustable dumbbells are one of the easiest ways to build a legitimate home gym without giving up an entire room.
A single pair can replace a large rack of traditional weights, making it possible to train your legs, back, chest, shoulders, arms, and core with relatively little equipment. Many of my virtual clients use adjustable dumbbells, and I have seen firsthand how useful they can be.
That doesn’t mean every adjustable dumbbell is right for every person. The best choice depends on how much weight you need, how quickly you want to change it, how much space you have, and how much you are willing to spend.
Best for Most Home-Gym Clients: BowFlex Results Series 552
The current BowFlex Results Series 552 adjusts from 5 to 52.5 pounds per dumbbell across 15 weight settings.
That range works well for many general-fitness clients because it provides lighter settings for shoulder work and other smaller movements while still offering enough weight for rows, presses, squats, and some deadlift variations.
The dial system is straightforward, and changing weights only takes a few seconds. The primary limitation is that the dumbbells remain fairly long, even at lighter settings. That can make certain exercises feel awkward for smaller clients or during movements where the weights need to remain close to the body.
The current model includes a two-year parts warranty, with longer protection plans available through BowFlex.
This is the option I would consider first for someone who:
• Wants one straightforward pair of dumbbells
• Primarily trains for general strength and health
• Needs both light and moderately heavy settings
• Values simple adjustments
• Doesn’t expect to need more than approximately 50 pounds per hand
A note for existing BowFlex owners: This recommendation applies to the current Results Series 552. Certain older SelectTech 552 and 1090 dumbbells were recalled in 2025. If you already own an older model, check its model and serial number on BowFlex’s recall page before continuing to use it.
Best for Long-Term Growth: PowerBlock Pro 100 EXP
The PowerBlock Pro 100 EXP can be purchased in stages and eventually expanded to 100 pounds per dumbbell.
That makes it a strong choice for someone who doesn’t need 100 pounds today but wants equipment that can grow with them. It also provides smaller weight adjustments at many settings, which can be particularly helpful when progressing upper-body exercises.
The main tradeoff is the shape. PowerBlocks don’t feel exactly like traditional dumbbells, and some people dislike placing their hands inside the frame. Other people love the compact design and never want to use anything else.
This is the option I would consider for someone who:
• Expects to become stronger than a 50-pound dumbbell allows
• Wants to purchase additional weight gradually
• Values compact equipment
• Wants smaller progression options
• Is comfortable with the enclosed PowerBlock design
Best Premium Traditional Feel: SMRTFT NÜOBELL 80
The SMRTFT NÜOBELL 80 adjusts from 5 to 80 pounds in 5-pound increments. Its open handle and weight-plate design make it feel more like a traditional dumbbell than many adjustable systems.
The twist-lock handle makes weight changes fast, which is useful during circuits or supersets. It also offers substantially more room for strength development than a dumbbell that stops around 50 pounds.
The drawbacks are the price and the 5-pound jumps. A 5-pound increase per hand can be significant during smaller shoulder and arm exercises. Like most adjustable dumbbells, these should also be handled carefully rather than dropped.
This is the option I would consider for someone who:
• Wants a more traditional dumbbell feel
• Needs up to 80 pounds per hand
• Changes weights frequently during workouts
• Values design and ease of use
• Is willing to pay more for a premium option

What to Consider Before Buying
Maximum Weight
Think beyond what you can lift today. Lower-body movements and rows will often require more weight than raises, curls, or smaller shoulder exercises.
At the same time, don’t assume that buying the heaviest available option automatically makes it the best. Your dumbbells need to provide useful weights at both ends of the range.
Weight Increments
Smaller jumps are particularly helpful for upper-body exercises. Moving from 10 to 15 pounds is a 50% increase, even though it only sounds like five pounds.
If you expect to perform a lot of shoulder, arm, or rehabilitation-focused movements, pay close attention to the available increments.
Dumbbell Length and Shape
Some adjustable dumbbells remain the same length regardless of the selected weight. Others become shorter when fewer plates are selected.
Longer dumbbells can feel awkward during curls, presses, and exercises performed close to the body. Enclosed designs may also feel unfamiliar if you are accustomed to traditional dumbbells.
Adjustment Speed
Fast adjustments matter if your workouts include supersets or circuits. They matter less if you take longer rest periods or use similar weights for several exercises.
Durability
Adjustable dumbbells contain selection and locking mechanisms that fixed dumbbells do not. They generally shouldn’t be dropped, thrown onto the floor, or treated like commercial-gym equipment.
Always make sure the selected plates are securely attached before beginning an exercise.
Your Actual Training Plan
Don’t choose a set based solely on the maximum number printed on the box. The best option is the one that supports the exercises you perform most often and gives you reasonable room to progress.
My Practical Recommendation
For many home-training clients, a pair that ranges from approximately 5 to 50 pounds is a strong starting point. Clients who already know they need heavier weights should consider an expandable system or a model that reaches 80 to 100 pounds.
Before purchasing, check the current specifications, warranty, return policy, and product-safety notices. Prices and models change, and a good set of adjustable dumbbells should be a long-term investment.
