Dumbbells Adjustable or Fixed, Which is Better?

Dumbbells Adjustable

As I began assembling equipment for my new home gym, one of the first dilemmas I faced was whether to invest in a set of dumbbells adjustable or traditional fixed dumbbells. Both options seemed to have advantages and disadvantages that made the decision difficult. Would the versatility and space saving design of adjustable dumbbells be worth the higher price tag? Or would I be better off sticking with standard plates and bars that have stood the test of time? 

After doing extensive research and talking with experienced lifters, I’ve determined that there is no one size fits all answer. Depending on your budget, workout space, strength goals, and preferences, either adjustable or fixed dumbbells could be the better choice for your home gym. This article examines the key differences between the two styles in depth so you can make an informed decision when purchasing your own set.

What Are Adjustable Dumbbells?

Adjustable dumbbells utilise a specialised barbell handle design that allows weight plates to be added or removed quickly to change the total amount of weight. Most adjustable dumbbell systems consist of a pair of handles and a set of weight plates. By sliding plates onto each end of the handle, you can customise the weight in increments, usually ranging from 5 to 50+ pounds. 

There are several popular adjustable dumbbell systems on the market, each with their own unique handle and plate changing mechanism. Spinlock dumbbells use a threaded lock nut to securely fasten plates. Dial or selectorized models have a rotating dial that allows you to dial into the desired weight. Powerblocks use a pin selector system to add or remove plates. Ironmasters, Bowflex, and Nuobell use a magnetic or latching system to secure weight plates.

In summary, the major benefit of adjustable dumbbells is the ability to have a wide range of weight options in one compact, space saving product. The convenience of changing weights quickly is a major selling point for adjustable systems.

What Are Fixed Dumbbells?

In contrast to adjustable dumbbells, fixed dumbbells have a set weight that cannot be changed. They consist of a solid cast iron or rubber hex handle with the weight permanently affixed on each end. To increase weight, you must purchase individual dumbbells of heavier weights. Most fixed dumbbells range from 1 pound up to 100+ pounds and are sold individually or in pre configured sets. 

While not as convenient for changing weight increments, fixed dumbbells have remained popular for several reasons. Their simple design makes them extremely durable and maintenance free. The fixed weight also allows very heavy dumbbells to be manufactured that adjustable systems cannot accommodate. However, the downside is that each weight requires its own dumbbell, quickly consuming storage space.

Choosing Between Adjustable and Fixed Dumbbells

When deciding between adjustable and fixed dumbbells for your home gym, there are several key factors to consider:

  • Budget: Adjustable systems have higher upfront costs but lower long term costs. Fixed dumbbells are cheaper individually but expensive as a full set.
  • Weight range needed: Adjustable accommodates a wider spectrum; fixed offers extreme light and heavy weights.
  •   Available storage space: Adjustable saves space; fixed requires individual storage spots.
  •   Workout goals: Adjustable offers incremental progress; fixed works for focused heavy lifting.
  •   Convenience: Adjustable quick changes; fixed avoids breakdowns and maintenance.


  • Adjustable dumbbells are ideal for space limited gyms needing a wide, incremental weight range.
  • Fixed dumbbells suit large budgets, focused heavy lifting, and durability.
  • A hybrid approach of adjustable handles for lighter weights and fixed dumbbells for heavy training combines benefits.

Recommendations for Common Goals

Here are my dumbbell recommendations for a few common home gym scenarios:

  • Beginners: Start with an adjustable set or a lighter fixed set of around 5 25 lbs for foundational strength training.
  • Intermediate lifters: Invest in an adjustable system with higher weight plate capacity to progress into heavy training. 
  • Advanced lifters: Utilise heavy fixed dumbbells up to 100+ lbs for intense lifts, plus adjustable handles for auxiliary exercises. 
  • Small spaces: Choose a compact adjustable system that provides a complete weight range without consuming storage room.
