Like many, you are most likely sick of promotions for particular sets of dumbbells that insist they are the best.  They generally claim that they can make your every dream come true.

Every manufacturer claims that they have the highest quality product.

Why should you trust them?

Simply because they received a few high reviews and claim to be the best?

Maybe you should approach the buying situation in a different way?

Following many attempts and failures I acknowledged that some of the advice from these sites became inaccurate and unhelpful.  I figured out that the right dumbbell for me may not be the correct match for another individual.  The buyer is the only one that matters and should do their own research in order to find the right adjustable dumbbell match for them.

Top 3 Adjustable Dumbbells Reviews

Below are our reviews on the top 3 adjustable dumbbells

Bowflex SelectTech 552

One of the most attractive aspects of this product is its price.  This is the most reasonable of the three reviewed products and is capable of being effective for all weight trainers, despite experience level.  The Bowflex SelectTech is great for those individuals that are just beginning their muscle toning process.  These weights allow you to increase weight by smaller increment levels as compared to the Weider dumbbell set.  These are the main reasons that I chose this set at the best value of the three. That being said, if you want something that is going to be cheaper and not adjustable, you can check out these cheaper dumbbell sets here.

The traits this set offers are key to a gradual increase in weight training.  You should not begin with too much weight for a number of reasons.  Your body may not be able to handle lifting that much extra weight, and you want to avoid injury and muscle stress.  Working your way up slowly helps you to be more successful during all of your weight training sessions.  As an example, if may not be a smart choice to jump from 10 to 25 pounds, as this can be too much for your muscles to handle.  Be sure to get the best workout and results by working in smaller increments.

Some other advantages worth noting:

  • Increased functionality due to smaller weight increments
  •  An incredible time of just 5-10 seconds to adjust the four dial and set a new weight
  • 15 to 30 seconds to adjust the set for a completely new workout
  • This set has the widest variety of weight setting, providing even more opportunities for muscle growth.

One of the major disadvantages of this dumbbell set is its size.  This is the bulkiest of the three options at 15” x 8” x 9”.

Ironmaster 75 lb Quick-Lock

The second dumbbell set on this list is this Ironmaster product.  This seems to be the most sturdy of the options and can be noticed by a great feeling of balance and may be because of its production in the USA.  Some other desirable aspects of the IronMaster dumbbells include:

  • This set offers the widest increments of weights ranging from 5 to 75 pounds, making them ideal for individuals that may want to intensify their workouts in the near future.
  • They have a very comfortable grip.
  • This is the most compact of the options at 14.5 inches long
  • These dumbbells are known for being great for press exercises.

A downside of this set is that take a little longer to change the weight settings.  This can be frustrating if you plan on doing curls or other exercises that require quickly changing the weight.  A second problem could be the lack of a locking mechanism for the screen in pins.  This could cause a safety concern during use because the plates may be more likely to fall off of the bar.  Just because there are not moving plates on this set does not mean that it is a safer product.  Considering the pins are not present, some worries may arise.  With that being said, there have not been any reported injuries as of this time.

Weider SpeedWeight 120

The final review will discuss the Weider product which possesses a multitude of aspects that made it one of my top three choices.  One of the best qualities is its six inch diameter, making it the smallest in diameter of the three.  This makes it look smaller than the others.  Other properties worth recognizing include:

  • The sets robust locking system and metal sliding
  • The high quality stand that is included with purchase

If you have the money, this is the dumbbell set to buy and is by far the best option.  This being said, there are some disadvantages as well.  As an example, this option has the fewest weight settings with only 10 as compared to the Bowflex with 15 and the IronMaster with 14.  The following are some aspects of the product that could be improved upon:

  • This set increases by an increment of five pounds.  This is disadvantageous for people who like to gradually increase weight during their workout.  A 10-pound interval is often too much for people and may overuse your muscles.
  • This set is the longest of the three reviewed products of top adjustable dumbbells.  This may not matter to some, but it can be a problem when discussing storage options.  Some say that lifting a dumbbell this long can be a bit awkward.

How to Find the Best Adjustable Dumbbells

These are just my opinion of these three adjustable dumbbells.  You can decide what your three favorite products are by making use of the following criteria.  While searching it is important to keep a few ideas in mind:

  • packaging
  • weight settings
  • price
  • increments
  • warranty
  • dimensions/size
  • durability

I tend to focus on price, weight increments, and settings when reading reviews by other customers.

Some people tend to be too money conscious when looking for the cheapest adjustable dumbbell, but you should make sure that you are getting a valuable and reasonable deal.  It may be helpful to calculate the cost per pound of each dumbbell.  With the three sets just reviewed their price per pound is $5.70/pound for the BowFlex, $7.05/pound for the IronMaster, and $6.70/pound for Weider.

Pay attention to weight increments and settings of adjustable dumbbells since these will be important aspects in the long run.  Try not to focus on the price as much as the dumbbells fit to your body and needs.  As an example, I believe the BowFlex set is the best since they allow you more freedom when choosing the weight of each dumbbell.  They range from 5 to 52.5 pounds.

Take my advice when I say that this range is incredible and will allow for a great deal of muscle improvement in the process of becoming a lean, mean, fighting machine.  Additionally, the 2.5 pound increments of the BowFlex provide gradual weight settings and 15 options, as compared to 14 and 10 in the other two sets cases.

Customer satisfaction should also be another concern as well, regardless of what you are purchasing.  Amazon reviews can help the buyer get a better idea of product quality so that you can make the smartest decisions.  Use other peoples’ reviews to your advantage.

Do not simply look at the rating of products.  Reviews say much more about quality and traits and show that the customer thought their opinion would be beneficial to others that were once in their position.  With this being said, it may be too time consuming to look at every review.

If time is short for you, looking at the highest rated reviews and their values may be the most beneficial.  If a product is rated as five stars, this may not mean that it is the best choice.  For example, Weider would appear to be the best based on ratings only, but this does not tell us the whole story.

The number of ratings and reviews can also be helpful.  Using Weider as an example, this product has a 100% 5-star rating but upon closer review, only one customer has provided input.  IronMaster and BowFlex have a 4.8 and 4.5 star rating respectively.

This being said, BowFlex would appear to be the least favored product, which is false, considering that this product has the most reviews of all three weight sets (564, compared to 1 for Weider and 78 for IronMaster).

With all of this being said, which would you purchase?  Would the 560 reviews or the one review item convince you?  Have you decided which is most credible?  I would go with the item that has the most good ratings instead of the highest average rating.


I would choose to purchase the BowFlex SelectTech 552 because of its long list of advantages and lack of disadvantages.  The high number of comments is a fact that is hard to ignore and is a good sign for this product.  Excellent reviews and the quality of this item have convinced me that it is one of the best and should be one of your top choices!

The other two reviewed products in this article are fantastic as well and are great values for their price.
