PowerBlock Dumbbells

Is the PowerBlock adjustable dumbbell system right for you?

If so, which specific model should you choose?

Keep reading to discover those answers and more…

…Here, you’ll find a comparison chart of all the PowerBlock models, my top recommendations, and videos & photos of each different PowerBlock dumbbell set.

This page is a comprehensive buying guide. I created it based of my findings when researching which adjustable dumbbell system to buy for myself…

…It’s worth noting that I ultimately decided to buy the Ironmaster Quick-Lock Dumbbells, though it was a tough choice to make.

My hope is that presenting what I learned about the PowerBlocks will enable you to accurately assess which (if any) PowerBlock set is the best adjustable dumbbell set for you.

Be sure to check out my PowerBlock dumbbells review, where I discuss the pros & cons of the PowerBlock system; plus some of its key contrasts with the Ironmasters.


A General Overview of the PowerBlock Dumbbells

As seen in the above video, there are three different series of PowerBlock dumbbells currently in production.

The three series include the Classic Series, the Sport Series and the Urethane Series. Then, within each series there are several different models, which I’ll present in detail later.

Some models are expandable, while others are non-expandable. That is, with some models you have the option to purchase add-on kits to increase the maximum weight, while others lack such options.

It is quite confusing to distinguish between the various series, models and add-ons, especially when you’re just starting to research them.

With so many models, each having its own unique set of features, capabilities and limitations, it takes some effort to familiarize yourself with not only the major distinctions between models, but also their more subtle ones.

This process of gathering, filtering and analyzing crucial product information takes hours of tedious online research and is very frustrating

…It’s the last thing you’d want endure when your aim is to simply buy a set of PowerBlocks and be done with it.

However, it would be foolish to make such an expensive investment without first attaining all the knowledge needed to make the correct choice.

And so, it is my goal to help clear up the confusion surrounding the PowerBlock dumbbells by presenting all the essential information in a coherent fashion.

PowerBlock Dumbbells Comparison Chart

Please read the paragraphs below for an important note regarding the information in the chart:

You’ll notice that some models in the chart below have different “stages” (i.e. Stage I, Stage II, Stage III)…

…What this means is that you can expand the weight capacity of the base dumbbell set (i.e. the Stage I set) with a Stage II and, if applicable, with a Stage III add-on kit.

So, you can buy just the Stage I model to begin with, and then purchase the add-on kit(s) separately, some time in the future. This method is best if you’re strapped for cash and/or don’t know if you’ll even need the extra weight capacity. (The chart does not contain the info about for the individual add-on kits.)

Alternatively, you can buy the dumbbell sets with the add-on kit(s) included. This is what the “Stage II” and “Stage III” models in the chart refer to. You save some money this way, as opposed to buying the base set and add-on kits separately.

For example: You could buy just the U-90 Stage I set now, and then have the option to buy the Stage II and Stage III add-on kits later. Alternatively, you could buy the U-90 Stage II set now and have the choice to buy the Stage III add-on kit later. Or, the third and final option would be to go all out and buy the U-90 Stage III set now, and have everything included from the get-go.

Where to Buy: You can purchase any of the PowerBlock dumbbells shown in the chart below, online at Amazon or PowerBlock.com.

* The Elite 50, Elite 90 and Elite 130 dumbbells are all part of the same expandable set. You can think of the Elite 50
as the “Stage I” base set; the Elite 90 as the “Stage II” set; and the Elite 130 as the “Stage III” set.

** The precise weight increments for the “Heavy Weight 125 lb” and the “Heavy Weight 125 lb + 50 lb Add-On” are
stated below:

  • 2.5 lb increments from 10-105 lbs (and from 130-175 if using the 50 lb Add-On Kit)
  • 3 lb increments from 105-125 lbs
  • 2 lb increments from 120-122 lbs

What’s the Best PowerBlock Dumbbell Model to Buy?

As I stated in the introduction, I do not own any of the PowerBlock dumbbells. As such, I can’t give you a recommendation based on personal experience…

But, having done so much in-depth research of the PowerBlock dumbbells, I can confidently tell you which models would be at the top of my list, if I were to choose a pair for myself (or anyone serious about lifting).

First off, I wouldn’t choose any of the models that aren’t expandable to at least 125 lbs. This narrows our choices to just four:

  1. Heavy Weight (expandable to 175 lbs.)
  2. Sport 9.0 (expandable to 130 lbs.)
  3. Elite (expandable to 130 lbs.)
  4. U-90 (expandable to 125 lbs.)

If money wasn’t a conern, my top choice would be the Heavy Weight dumbbell set for the following reasons:

  • It is expandable to the heaviest weight capacity of 175 lbs.
  • It has the fewest unavailable weight increments (i.e. more weight options, which makes strength progression easier)
  • It has the best warranty offered by PowerBlock, Inc. It lasts 15 years and covers defects, damage from normal use and drops from up to 12 inches above the ground. (Note: The U-90 has the same warranty.)

If, however, money was a conern, my next choice would be one of the Sport 9.0 sets, because:

  • It is expandable to the second heaviest weight capacity of 130 lbs.
  • It has more available weight increments beyond 100 lbs than the U-90.
  • It a 15 year limited warranty, which covers manufacturer defects as well as damage from normal use and drops from as high as 12 inches. This is the second best warranty offered on all PowerBlock models.

The Elites and the U-90s are tied for my third/forth choice. It’s too difficult a decision to choose a clear-cut winner, without actually testing each one first…

…Each model has its own positives and negatives, described below, which make it a toss up between the two.

  • The Elites are more affordable and have more weight increment options beyond 100 lbs.
  • The U-90 models, however, have a superior build quality. Also, it has a better warranty than the Elite set. The warranty for the Elites lasts only 10 years (as opposed to a lifetime for the U-90) and only covers drops of up to 6 inches (as opposed to 12 inches for the U-90) above the ground.
