Today we are going to make a comparison of the Lullax Neo40 adjustable dumbbells of 40 kg. and the Bowflex, which you already know that I have them for a long time, the Bowflex adjustable dumbbells of 41 kg. They are similar but have a lot of differences. Also, I bring you a special offer that we got for all of you.
We will see the qualities of these dumbbells, their differences and the innovations that brings the adjustable dumbbell Lullax Neo40 against the veteran Bowflex. I leave here a link to the dumbbells, with the 💸 coupon discount Lullax BILBOTEAM10 and you will have a 10% discount on automatic weights, adjustable dumbbells in Official Lullax Store Adjustable Dumbbell NEO40 and other models of dumbbells for training.

Key Differences Between Lullax Neo40 and Bowflex Adjustable Dumbbells
The differences, apart from the size of the adjustable dumbbells, which in the Bowflex is superior, and that the Lullax are more compact, is the way in which we select the weight. In the adjustable dumbbells Lullax Neo40 in which it is varying in the middle a pin that as it is advancing it is taking discs. In the Bowflex we have a selector in each one of the lateral ones and it is choosing the disks depending on the weight that you are going to choose.
Design and Size: Compact vs. Bulky
So, for example, here in the Lullax Neo40 if we have them taken with the smallest weight which is 4.5 kg, you would take out the dumbbell and only the first disc comes out, shortening in length and making it compact and manageable. In the Bowflex having selected the 4 kg comes out without any disc, but here the differences begin. It always comes out the total of the dumbbell in all its length, being much bigger than the adjustable dumbbell Lullax that you only take out a small dumbbell.

Weight Selection Mechanism: Adjustable Weights Lullax Neo40 Simplicity
When selecting the weight, on the Lullax NEO40 adjustable dumbbells all you have to do is turn the middle handle, the area where you grip the dumbbell. If you turn you increase the weight. If you select 9 kg and two discs come out.
On the Bowflex you have to rotate in two places, you have to rotate the side weight selector, for example on the right, and then on the left side and then repeat on the other dumbbell. So it’s three steps when on the Lullax it’s just one, where you turn to the weight you want and you pull the dumbbell straight out.
So the Lullax NEO40 is far superior to the Bowflex, because every time we have to select the weight on the Bowflex we have to keep turning it as if it were a safe. For example, you look for the 11 for 11 kg, you look for it on the left side and, you take it out, the selected discs come out so that they are 11 kg.

The problem is that, for example, when you pick up and say to put 14 kg, on one side you see the number right side up, and on the other side it’s the other way around, you start looking for 14 kg, but it’s really 41, it’s not 14. So it takes you a while, that is, you lose a little bit of time in terms of preparing the dumbbells when in the Lullax NEO40 adjustable dumbbell is much easier, in the Lullax I have selected 9 kg, I turn to the plus and I already have 13 and a half and a little more and 18, you have to take into account that the weight jumps in the Lullax are greater. But in terms of ease of weight selection it is better. The Bowflex dumbbells have slightly smaller jumps. I indicate in the following table the jumps so that you can compare them.
Comparative Table: Weight Jumps

Material Safety and Quality
As for the quality of the dumbbells, I’ve had the Bowflex dumbbells for a long time, they go pretty well, yes, there have been times when a disc seemed to have fit wrong and has given some failure, but I’ve never dropped a disc. That is to say, if the dumbbell is not in place you can not remove the discs, it has to be embedded in its support. If not, the discs will not come out.
Now, the Lullax NEO40 adjustable dumbbells have one thing that I like and give me much more confidence, because when I’m doing an incline press and you have the discs on your face, the truth is that with the Bowflex I always get a little scared because of the opening that the Bowflex discs have and that makes you think that the disc can fall, that it can break with a little tab and fall on your face. I tell you that I have never seen it happen and it has never happened to me.
The good thing about the Bowflex is that at any weight you choose, you pull it out and the metal plunger is there in the middle, that is, it moves forward and picks up the discs, in addition to the polyurethane hooks that prevent them from slipping out, and they fit one on top of the other. So if we keep increasing the weight, the plunger moves forward and picks up the discs, so it seems to me to be an extra safety measure. I think it’s a safety measure. You won’t be able to drop the disc on top of it because apart from the polyurethane hooks, you have the metal plunger that goes in the middle.

As for the quality of the inside of the dumbbell, they both have that metallic feel. In the Bowflex dumbbells when you are turning the roulette you see that there is something metallic that gives confidence. And in the adjustable weights Lullax NEO40 the same thing, when you are turning you notice that metallic click inside that for me gives quality and robustness to this type of dumbbells and the mechanism is based on turning the roulette and a metallic plunger that goes to both sides.
The ease of use and comfort of either of the two adjustable dumbbells are good, they are very good, for me they are the top of what you can find in terms of adjustable dumbbells. The Bowflex came out a long time ago and of course for me the Lullax NEO40 adjustable dumbbells are like an evolution.
So Bowflex I think you have to get your act together and renew the system, because Bowflex is a very good brand, Bowflex is a very good brand, top, and Lullax is proving that as well.
As for the ease of use, you already know that on the Lullax dumbbells you simply rotate once and you have selected the weight and take it off, and on the Bowflex you have to rotate on both sides and then lift the dumbbell.
Comfort of use and grip of the best adjustable weights.
In the Lullax NEO40 I check that we have a rough handle that does not skid at all, it is completely round and a little fatter than normal, it is not a fat grip but it is fatter than normal, it is even a little bit fatter than the powerlifting bar, it is quite comfortable and pleasant to use, I really like it.
In the Bowflex that also have a rough grip, with a mottled that does grip well but unlike the Lullax is not round, it’s like a square, it’s a little weird and when you’re carrying a little heavy it can hurt your hand a little, it’s like you try to place it where it best supports you in your hand.

As for the grip, it is much better than the Lullax NEO40 adjustable weights. I think Bowflex has made this grip so that you always have to fit it in your hand, because of course if you put it on the back of your hand it will slip because it is smooth. So they make sure that you will always have the mottling on your finger and on the palm of your hand. That way when you pose them again you always have them vertical.
Maneuverability During Exercise: dumbbell press, inclined press
As for the size of the dumbbells, here I say: size does matter. The problem with the Bowflex is that once you get the minimum weight, they are huge compared to the Lullax. This limits you a lot to do exercises like a curl, it’s going to hit your leg. The Lullax adjustable dumbbells with any weight is like a normal dumbbell, it’s like the ones you find in every gym. With the Lullax NEO40 adjustable dumbbell you can do the exercise as you want because it is much more manageable.
The problem is that when you go to do a press or an incline press or a shoulder press, with the Bowflex dumbbells, if you go a little heavy, they have the outer rubber that bothers, it ends up bothering a little. It is tolerated because it is plastic, although you can get a little bit stuck in the leg, it is not as uncomfortable as some that have an iron tip and you can not support it.
However, the Lullax NEO40 dumbbells are completely smooth, in this they are also superior, they are much easier to put on the leg, to support and much easier to throw without fear, because it does not matter where you support it.
If we’re going to do a shoulder press, with the Bowflex you have to be careful, you have to have it a little bit wider apart because if you don’t, when you come down you’re going to rip your ears off. However, with the Lullax, you have a lot more space.
Easy to leave adjustable dumbbells in the holder
Additionally the Lullax are much more manageable when it comes to leave them on the stand. Let’s see, both models have that little point that you have to find the right place, but with the Bowflex you have to fit the discs, sometimes it’s a bit more complicated because you have to look for the place, but once they fit, you drop them and they go to the place. With the Lullax NEO40 you just snap them in the middle and put them in.
How delicate is this material? Well, I’ve been using Bowflex for a very long time and it hasn’t given me any problems. But since I got the Lullax NEO40 I haven’t gone back to using the Bowflex. I’m using the Lullax all the time and they don’t give me any problems either. Of course, the gym equipment is mine and I take care of it, and if you get on top of it, you’re going to ruin this or any other equipment.
Even the Bowflex indicate it with a little drawing saying, please, do not throw the dumbbells on the floor, do not drop them, it is a delicate material, delicate as far as it goes, they are weights, they are hard, they are metallic, but of course, they are not made for you to drop them on the floor, because if they fall flat maybe nothing happens to them, but if they fall like that, I am sure that at the third fall you will be left without dumbbells. So I think they are sturdy enough to last for many years, but you have to use it as a material, because it is yours.
