Bowflex vs Powerblocks Dumbbells (2024) Which Is Better?

As a fitness trainer with years of experience, I've had my hands on countless weights, and for the longest time, I was skeptical about adjustable dumbbells.

I'd often suggest traditional sets to my clients, citing the cumbersome adjustment process and limited exercise range of the adjustable ones.

But Bowflex and Powerblocks changed my perspective. I spent several months testing these dumbbells, and I also had several of my clients compare them. Here's how they fare, from grip comfort to weight transition speed and more, so you can choose the best one for you.

We also compared ​PowerBlock vs IronMaster, another popular product on the market.

I teamed up with a group of my clients to put these two adjustable dumbbells to the test. To ensure fairness and objectivity, I divided them into two distinct groups. Over the course of a month, each group exclusively used one set of dumbbells for their training routines.

Before diving into the test, I meticulously recorded their initial fitness metrics to gauge progress accurately.

At the end of the month, while both groups showed improvement, one group notably outperformed the other in terms of strength gains and adaptability to the equipment.

Let's get into the head to head comparison, and pros and cons of both dumbbells.

From my years of training, I've tried various dumbbells, but the Bowflex adjustable ones hold a special place. Their dial system, in my experience, is not just innovative but incredibly user-friendly, especially during intense sessions. I know some people prefer a selector pin, but I have found that after a few goes, you should be able to adjust them much faster.

Bowflex 552 vs. Bowflex 1090.

The Bowflex SelectTech 552 set gives you from 5 pounds all the way up to 52.5 weight range settings. That's quite impressive, thus many users consider ​this equipment the best adjustable dumbbell set. In comparison, a set of traditional dumbbells could cost you many times as much to get the same kind of range.

The weight range of ​Bowflex 552 is also great for a beginner.

There's also the Bowflex SelectTech 1090, which has the same features as the 552. The only difference, however, is that you can adjust it from 10 to 90 pounds. All you need is to adjust the built-in dial found on the sides.

This dumbbell is perfect for those who are looking for more weight that goes beyond the 552 weight range.

Durability and Safety of Bowflex Dumbbells

The Bowflex dumbbell's durability is also impressive. You won't even have to fear dropping them accidentally because there are no fragile or plastic parts that will break.

According to the article in Harvard Health Publishing, safety should always come first when it comes to strength training [1].

I also like that the warranty lasts for two years, which gives you some added peace of mind in case things go wrong.

Now, you’ll probably adjust to the pin system quickly, which is quite similar to what you see on gym machines. But, PowerBlock's weight adjustment is not quite as fast and seamless a movement in comparison to the Bowflex.

There's also a PowerBlock Compact Weight Stand available if you wish to have convenient storage for stacking your PowerBlock adjustable dumbbells.

When you’re trying to make a decision between PowerBlock vs ​Bowflex, I would suggest that you take a look at your personal workout program, goals, and needs before your purchase.

Here’s what I recommend to my clients when it comes to the PowerBlock vs Bowflex brands dilemma.

Bowflex is excellent for quick weight changes during workouts and is more compact, making it suitable for smaller spaces.

PowerBlock, although slower in adjusting weights, offers stability and a comfortable grip, with the Elite model nearly matching Bowflex in terms of weight increments.

If speed is not a must-have, and you want to save a few dollars as well, the PowerBlock Elite might just be the best adjustable dumbbells on the market.

Both products are also excellent in terms of durability and quality. Unlike other adjustable dumbbells that have plastic parts, the Bowflex and Powerblock sets are made of metal.

Safety Precautions for Bowflex and Powerblocks Adjustable Dumbbells

The unique designs of these dumbbells have specific safety considerations:

• Bowflex's dial system: Always ensure the dials are securely set to your desired weight before lifting. Misalignment can cause an uneven weight distribution or even cause plates to detach during exercises.
• Powerblocks' magnetic pin system: Before each exercise, double-check that the pin is fully inserted and securely held by the magnet. An improperly placed pin can lead to weights dislodging during a workout.
• Weight transition: For both dumbbells, adjust weights while they are on the ground or their respective stands. Lifting them during change increases the risk of dropping or misaligning the weights.
• Regular maintenance: For Bowflex, ensure the dial turns smoothly without jamming. For Powerblocks, ensure the magnetic pin isn't worn out and retains its magnetic strength.
• Avoid dropping: While traditional dumbbells might withstand drops, the intricate mechanisms in Bowflex and Powerblocks can be damaged by impact. Always set them down with care.

Having spent considerable time with both the PowerBlock and Bowflex dumbbells in my home gym, I've come to appreciate the unique features each brings to the table.

While both are top-notch in quality, my personal preference leans towards the Bowflex series.

The dial adjustment system, from my experience, offers a tad more convenience, especially during those high-intensity workouts where every second counts. It's all about finding what aligns with your routine and comfort, and I found the Bowflex provides more flexibility.

With their ease of use and excellent quality, Bowflex will have you excited to work out every day.
