Best Adjustable Dumbbells For Crossfit: Buyer’s Guide

The best adjustable dumbbells for CrossFit combine fast weight changes, a secure grip, and enough range for varied workouts.

You start a WOD with light thrusters, move to heavy deadlifts, then finish with high-rep snatches. Changing tools each time wastes space and breaks your pace. The right adjustable dumbbells solve that problem. I reviewed these sets for grip, loading speed, stability, storage, and CrossFit use. I also looked at value, workout range, and common buyer concerns so you can choose with confidence.

See the differences between my top picks at a glance.

28 lb Adjustable Dumbbell Set

Check the Price on Amazon

This 28-pound adjustable dumbbell set offers 11 weight options in one dumbbell. That makes it a useful pick for small rooms, travel, and simple home workouts. The single-dumbbell format suits one-arm rows, presses, carries, and split movements. It also keeps the entry price and storage demand lower than a full pair.

For CrossFit, I would use it for technique work, conditioning, and moderate strength sessions. The compact format lets you move from curls to presses without a large rack. Still, one dumbbell means you must switch sides during many movements. It works best for newer athletes or anyone who needs a light, space-saving tool.

Pros:

• Offers 11 weight options
• Uses very little storage space
• Supports one-arm training
• Useful for home and travel workouts
• Costs less than many heavy pairs

Cons:

• Only one dumbbell comes in the set
• 28 pounds may limit advanced strength work
• Plate changes take longer than a dial system

What Amazon Buyers Are Saying

Buyer feedback for compact adjustable sets often centers on value, small size, and workout variety. Buyers tend to like having many weight choices in one unit. Common concerns include the time needed to change plates and the limits of a single dumbbell. Check the current listing reviews for the latest fit, locking, and durability comments before ordering.

My Recommendation

I recommend this set for beginners, small apartments, and athletes who want a light dumbbell for conditioning. It is not my first choice for heavy two-arm CrossFit work. It earns a good score for simplicity and space savings.

Rivotrance Olympic Dumbbell Handles

Check the Price on Amazon

The Rivotrance handles give you a loadable dumbbell setup for 2-inch Olympic plates. This design suits lifters who already own Olympic plates. You choose the load by adding or removing plates on each side. The chrome finish also gives the handles a traditional gym look.

These are better for strength-focused CrossFit sessions than for fast, repeated weight changes. You can build a heavier dumbbell for deadlifts, rows, and presses. However, plate size can make the dumbbell wider than a fixed or dial model. Always tighten the collars and test the setup before explosive work.

Pros:

• Works with 2-inch Olympic plates
• Allows custom loading
• Can support heavier training than light sets
• Useful for athletes who own plates
• Traditional handle design feels familiar

Cons:

• Plates are not included with the handles
• Loading takes time between movements
• Large plates may affect range of motion

What Amazon Buyers Are Saying

Buyers of loadable handles commonly value their flexibility and compatibility with existing plates. They also point out that collars must stay tight during use. The usual complaints for this product type involve plate wobble, awkward bulk, or slower transitions. Review the current customer comments to confirm how the collars fit your plates.

My Recommendation

This is a smart choice for a garage gym with Olympic plates. I would choose it for heavy rows, presses, and strength work. I would not choose it as the only tool for a fast chipper with many weight changes.

UNNMIIY Adjustable Dumbbell Set

Check the Price on Amazon

The UNNMIIY adjustable dumbbell range stands out because the listing offers 20, 30, 45, 70, and 90-pound set options. That gives you a path from basic training to heavier work. It can suit athletes with changing goals and families who need different loads. The adjustable format also cuts down on the number of separate dumbbells in your gym.

For CrossFit, the right size matters more than the biggest number. A lighter set may work well for high-rep snatches and presses, while a heavier set can support rows and deadlifts. Larger loads may feel bulky during fast movements. I suggest checking the exact option, included parts, and dimensions on Amazon before you buy.

Pros:

• Offers several listed weight options
• Supports long-term strength progress
• Reduces the need for many fixed dumbbells
• Fits varied home gym needs
• Can cover both light and heavy sessions

Cons:

• Each weight option may have a different price
• Plate-style changes may slow a WOD
• Heavy models can take more floor space

What Amazon Buyers Are Saying

Customers shopping in this category often praise the broad size choice and the chance to expand over time. Some buyers also mention that assembly, locking parts, and product size deserve close attention. The experience can vary by selected weight option. Read reviews for the exact option shown in your cart, not only the general product page.

My Recommendation

I recommend UNNMIIY for athletes who want a growth path. It is one of the better choices here for mixed strength levels. Select a weight that you can control during overhead and fast movements, rather than buying the largest option by default.

BCBIG 20 lb Convertible Dumbbell Set

Check the Price on Amazon

The BCBIG set provides two 10-pound dumbbells for a listed 20-pound total. It can also convert into a barbell, which adds useful variety for home training. The light load suits beginners, mobility work, and higher-rep circuits. Its pair format also lets you train both arms at the same time.

This set makes sense for light CrossFit workouts and general fitness. It can handle movements such as presses, rows, lunges, and controlled squats. It will feel limited for stronger athletes during deadlifts or heavy dumbbell cleans. Treat the conversion parts as a feature for variety, not as a replacement for a full Olympic barbell.

Pros:

• Includes a pair of dumbbells
• Converts to a barbell
• Useful for beginners
• Supports bilateral movements
• Works well in small home gyms

Cons:

• 20-pound total load limits progression
• Not ideal for advanced strength work
• Conversion takes time between exercises

What Amazon Buyers Are Saying

Buyers tend to like the low price, simple setup, and barbell conversion. The most common concern with light convertible sets is limited load for stronger users. Some buyers also prefer a tighter, more solid feel during movement. Check current reviews for comments about the collars and the conversion connection.

My Recommendation

I recommend BCBIG for beginners, teens, light home workouts, and shared family use. It offers more exercise choices than a basic pair. Advanced CrossFit athletes should choose a heavier system.

FDS1 45 lb Adjustable Dumbbell Set

Check the Price on Amazon

The FDS1 adjustable set lists a 45-pound load and five exercise formats. It can work as dumbbells, kettlebells, a barbell, and push-up stands, depending on the included parts and setup. That broad design appeals to people who want one compact home gym system. The upgraded nut mentioned in the listing aims to support a secure plate connection.

I like this concept for mixed CrossFit accessory work. You can use dumbbells for presses, a kettlebell format for swings, and the bar setup for selected strength movements. Each conversion takes a little time, so it is not perfect for a nonstop WOD. Still, it gives a small gym more training options without buying every tool separately.

Pros:

• Listed as a 45-pound set
• Supports five exercise formats
• Can serve several home gym roles
• Useful for strength and conditioning
• Good choice when storage is limited

Cons:

• Conversions interrupt workout flow
• Load may feel modest for advanced users
• More parts require careful storage

What Amazon Buyers Are Saying

Review patterns for multi-function sets usually highlight the number of exercises available from one purchase. Buyers also tend to discuss setup time and how firmly the parts connect. Some users prefer the convenience, while others want a dedicated tool for each movement. Read current comments to learn how the included connectors perform in daily use.

My Recommendation

FDS1 is worth considering for a compact home gym or beginner CrossFit setup. It offers more value when you will use several configurations. I would choose a dedicated dumbbell system instead if fast transitions matter most.

BowFlex Results Series 552 SelectTech

Check the Price on Amazon

The BowFlex Results Series 552 SelectTech dumbbells use a dial-based adjustment system. That design makes weight changes much faster than removing several plates by hand. The pair format also suits two-arm presses, squats, and carries. BowFlex has a strong name in adjustable home fitness gear, which adds confidence for shoppers who want a polished system.

Fast changes matter in CrossFit. You can move from a lighter conditioning load to a heavier strength load with less interruption. The dumbbells still need careful placement on their bases before you turn the dials. They may also feel larger than traditional fixed dumbbells, so practice cleans and snatches with control.

Pros:

• Dial adjustment saves time
• Comes as a pair
• Supports many full-body movements
• Strong fit for changing WOD loads
• Recognized home fitness brand

Cons:

• Requires careful use of the base
• Adjustable shape may feel bulky
• Usually costs more than basic plate sets

What Amazon Buyers Are Saying

Buyers commonly value the quick dial changes and the clean storage footprint. Many adjustable-dumbbell owners also stress the need to set the handle fully into the base before changing weight. Complaints in this product category often involve bulk, mechanical parts, or shipping damage. Check recent reviews and the warranty details before purchase.

My Recommendation

For most athletes who want the best adjustable dumbbells for CrossFit, this is my leading pick. The fast adjustment fits interval work and mixed WODs better than plate-and-collar designs. I rate it highly for convenience, but I would still use careful form during explosive lifts.

ALTLER 52 lb Adjustable Dumbbell Pair

Check the Price on Amazon

The ALTLER set includes a listed 52-pound pair, a tray, weight dials, and anti-slip handles. This combination targets users who want a neat storage solution and quick load changes. A pair lets you train both sides together. The tray also gives each dumbbell a clear resting place between sets.

This set looks suited to strength circuits, presses, rows, lunges, and carries. The dial system should reduce the delay between movements, though you still need to follow the adjustment instructions. The anti-slip handle may help during sweaty sessions, but grip comfort remains personal. I would test the handle width and balance with light loads before a fast workout.

Pros:

• Listed as a 52-pound pair
• Uses weight dials
• Includes a storage tray
• Offers anti-slip handles
• Works well for paired exercises

Cons:

• Dial parts need careful handling
• May feel large for small hands
• Exact adjustment steps need review

What Amazon Buyers Are Saying

Customers who choose dial sets usually like faster changes and less floor clutter. Buyers also often mention handle comfort, tray quality, and how smoothly the selector turns. Common concerns include the size of the dumbbell head and long-term confidence in moving parts. Read the latest reviews for the exact set configuration.

My Recommendation

ALTLER is a strong middle-ground option for athletes who want a pair, a tray, and a useful listed load. It suits home strength circuits better than a single light dumbbell. I would pick it when storage and quick changes matter almost as much as price.

Amazon Basics 38 lb Adjustable Set

Check the Price on Amazon

The Amazon Basics adjustable hand weight set offers a listed 38-pound load and a storage case. Its traditional design uses removable plates, which keeps the system easy to understand. The case helps keep the parts together after training. This makes it a practical choice for basic home lifting and beginner strength work.

It can support rows, presses, lunges, squats, and controlled curls. It is less suited to fast CrossFit transitions because plate changes take time. The threaded parts also need regular checks during use. I like this set for steady strength sessions where you control the pace.

Pros:

• Includes a storage case
• Simple plate-based design
• Useful for basic strength training
• Easy to store after workouts
• Recognizable value-focused brand

Cons:

• Changes are slower than dial systems
• 38 pounds may not suit advanced athletes
• Loose parts can clutter the workout area

What Amazon Buyers Are Saying

Buyers often like the low cost, basic function, and included case. Common comments for this type of set focus on plate changes, collar tightness, and the limits of the included load. Some users want a faster system for circuits. Check current reviews for the latest comments on the case and threaded parts.

My Recommendation

This set is worth buying for basic lifting on a budget. It is not the fastest choice for a timed CrossFit workout. I would choose it for controlled sessions, beginner training, and users who want a simple storage case.

yuhqc 16-Inch Olympic Dumbbell Handles

Check the Price on Amazon

The yuhqc set includes 16-inch Olympic dumbbell bars and two pairs of collar clips. These handles accept 2-inch Olympic plates, so you can set the load to match your training. The longer bar gives room for plates and can help users who need more loading space. This is a good fit for lifters who already own compatible plates.

Loadable handles suit heavy rows, presses, lunges, and carries. They also let you adjust each dumbbell on its own. The tradeoff is clear: every load change takes hands-on work. For CrossFit, I would use them for strength days or planned sessions, not rapid ladder workouts.

Pros:

• Uses 2-inch Olympic plates
• Includes two pairs of collars
• Supports custom loading
• 16-inch length gives loading room
• Useful for home bodybuilding and strength work

Cons:

• Plates are purchased separately
• Collars need regular checks
• Long handles may feel bulky in some movements

What Amazon Buyers Are Saying

Buyers of Olympic handles usually appreciate the freedom to use plates they already own. They also discuss the fit of the collars and the feel of the longer bar. Common limitations include bulk and slower transitions. Read current customer reviews to confirm compatibility with your plate brand.

My Recommendation

I recommend yuhqc for experienced home lifters who own Olympic plates. It offers strong loading flexibility and good value when used with an existing setup. It is not the most convenient choice for fast CrossFit intervals.

How to Choose the Best Adjustable Dumbbells for CrossFit

Choosing the best adjustable dumbbells for CrossFit takes more than comparing the largest weight number. CrossFit blends strength, speed, skill, and endurance. A dumbbell that feels good for slow presses may feel awkward during snatches or cleans. Use the points below to match the tool to your training.

1. Match the adjustment system to your WOD pace

Dial systems work best when your workout changes weight often. You can move from light raises to heavier rows with less downtime. Plate-and-collar sets cost less in many cases, but they take longer to change. Loadable Olympic handles suit planned strength work, especially when you already own plates.

Think about your real workouts. If you follow timed intervals, fast weight changes can protect your work time. If you lift in straight sets, a slower plate system may offer better value. A quick system only helps when it stays secure and easy to use.

2. Check grip, balance, and movement clearance

A good dumbbell needs a firm handle that does not twist in your palm. Look for a shape that feels stable during presses, carries, and rows. Anti-slip details can help, but no handle replaces a dry grip and sound technique.

Also check the size of the weight plates. Wide plates can touch your forearm during presses or hit your body during cleans. Adjustable dumbbells often feel longer than fixed dumbbells. Practice with a light load before using them in a fast WOD.

3. Compare the true load, pair format, and value

Read the listing closely. A “20-pound set” may mean 20 pounds total, not 20 pounds per dumbbell. A single dumbbell costs less but forces you to switch sides. A pair costs more, yet it supports two-arm movements and keeps a workout balanced.

Count the parts you need. Olympic handles need compatible plates. Convertible systems may include several connectors. Dial sets need a safe base and careful placement. The best adjustable dumbbells for CrossFit give you the load range, speed, and control you will use often.

Final Verdict: Which Should You Buy?

For most athletes, the BowFlex Results Series 552 SelectTech is the best adjustable dumbbell for CrossFit. Its dial system supports quick changes, and the pair format suits varied WODs. Choose UNNMIIY for broader weight options or Rivotrance and yuhqc if you already own Olympic plates.

Pick the set that matches your pace, grip, space, and strength level. The best adjustable dumbbells for CrossFit should make training smoother, safer, and easier to repeat.

FAQs Of best adjustable dumbbells for crossfit
