I Recommend the 40kg Rythin Helix Mirror: An 8-Year Home Workout Veteran Compares the 20kg, 32kg, and 40kg Models

Hello! I'm Torimune, and I've been doing home workouts for 8 years.

In this article, I will explain which model you should choose among Rythin's popular adjustable dumbbells, the "Helix Mirror" 20kg, 32kg, and 40kg versions.

I'll start with the conclusion.

If your goal is muscle hypertrophy at home, I would choose the 40kg model without hesitation.👇

However, it's not just for the simple reason that it's the heaviest.

After carefully examining the product specifications and inquiring with the manufacturer, I discovered an important fact that I hadn't noticed before purchasing.

That is,it is not practical to buy the 20kg or 32kg models and later purchase additional parts to expand them to 32kg or 40kg.that is the case.

Home workout equipment is not a cheap purchase. That is precisely why,not regretting your initial choice

is more important than anything else.

I should clarify beforehand that I have not actually used the Helix Mirror. Therefore, this article is not a so-called usage review.

Based on the specs released by the manufacturer and my 8 years of experience with home workouts, I will look at it as objectively as possible from the perspective of,Would I want to choose this dumbbell if I were buying one today?perspective.

In this article, I, with 8 years of home workout experience, will compare the Helix Mirror's

• 20kg

• 32kg

• 40kg

and write my honest opinion from the perspective of "which one would I buy if I were in your shoes now?"

I hope this article will be helpful for those considering purchasing the Helix Mirror.

You cannot increase the weight of the Rythin Helix Mirror later

Actually, I had considered purchasing this Helix Mirror before. I thought, "Wouldn't it be fine to buy the 20kg or 32kg first, and then just add plates later if it's not enough?"

On the official Rythin page, there is information regarding the model parts as follows.

Since I couldn't quite understand this from the product page alone, I contacted Lysin directly to ask.

In response, I received the following answer.

In other words,it's not as simple as just adding plates.

You also need to buy additional shafts and bases. In my opinion, if you're going to go that far,it feels almost like buying the whole unit over again.

The moment I learned about this specification,I felt that "choosing the initial weight is more important than I thought."I felt that.

Home workout equipment is something you use for many years. That is precisely why I recommend thinking not about the "weight you can use now," but about the"weight you can use years from now."

Reasons why I do not recommend the 【Helix Mirror 20kg】

From here on, I will write down my thoughts on each weight.

First, the"20kg model"👇

To conclude,I do not recommend it.

Of course, I am not dismissing the 20kg weight itself. In fact, I still use adjustable dumbbells with a maximum of 20kg to this day.

They are still in active use for isolation exercises like side raises and arm curls.

However,if the premise is "buying a Helix Mirror," the story changes.

There is a reason for this.

Reason 1: There are models with better cost-performance in the 20kg range

The biggest appeal of the Helix Mirror is,

• the availability of a 40kg maximum model

• Adjustable in 1kg increments

• Long-lasting

These are the three.

Conversely, the 20kg model cannot fully utilize these benefits.

In the 20kg range, there are several other adjustable dumbbell models that are more affordable and offer similar ease of weight adjustment.

In fact, I recommend the 24kg model to beginners and intermediate users👇

The balance with the price is excellent, and it has more than enough performance to start home training.

That is precisely why, if you are choosing a high-end product like the Helix Mirror, I honestly feel that 20kg is a waste.

Reason 2: Chest, legs, and back muscles surprisingly reach their limit quickly

I also initially thought, '20kg is plenty heavy.' But as I continued home training, the first muscle group to hit a plateau was my pectoralis major.

As my dumbbell bench press gradually improved, I found myself able to do 10 or more reps at 20kg. By that time, I naturally started wanting heavier weights.

The same goes for the legs and back. In compound exercises that use large muscles, there is a high possibility that 20kg will become insufficient if you keep training.

Of course, there are individual differences, but if you are thinking, 'I want to continue home training for a long time,' you won't regret choosing with the possibility of future insufficiency in mind.

Reason 3: High probability of needing to replace it eventually

And this is the biggest reason.

As I introduced at the beginning of this article, the Helix Mirror is not a product where you can easily increase just the weight later on.

In other words, when 20kg is no longer enough, you will need to purchase not just additional plates, but also the shaft and the base.

Even if you intended to save money at first, your total expenditure will increase in a few years. I think this is quite a waste.

So, I am not denying the 20kg model itself. However, if you are choosing a high-end product like the Helix Mirror, the benefits of choosing the 20kg model are small.

This is my honest opinion after 8 years of home training.

The [Helix Mirror 32kg] is a model that falls just short

Personally, I overwhelmingly recommend the 32kg model over the 20kg one👇

In fact, for most people, 32kg is enough for several years of training.

• Dumbbell Bench Press

• Shoulder Press

• One-Arm Row

• Dumbbell Squat

If you are a beginner at home training, your muscles will grow significantly with this much weight.

So, it is by no means a bad model. In fact, it is quite attractive.

However... when you consider continuing home training for a long time, it falls just a little bit short.

I myself thought for the first year or two of home training that I would never be able to handle 40kg.

But it is a strange thing about continuing strength training; the weight you can handle gradually increases.

The dumbbell bench press, which was limited to 20kg at first, became 25kg, then 30kg, and before I knew it, I was challenging weights over 30kg.

Of course, I am not saying everyone will be able to handle 40kg immediately. But,
"I want to challenge heavier weights!" is a natural thought, which is the interesting part of strength training.

And, strength training that challenges high weights is incredibly exciting.

As you continue home training, it is quite possible that 32kg will eventually feel insufficient.

And at that point, you might think, "I wish I had just gone with the 40kg from the start..."

That is why I consider the 32kg to be a "model that falls just short".

It is enough for now. But when you think about a few years down the line, you want just a little more room to grow.

That is my impression.

3 Reasons Why I Recommend the [Helix Mirror 40kg]

If I were buying a Helix Mirror from scratch today, I would choose the 40kg model without hesitation.👇

The reason is simple.

“Because it lasts for years and is the most suitable for muscle hypertrophy.”

That is all there is to it.

Reason 1: No need to replace it, making it the best long-term value

This is the biggest reason to choose the 40kg model.

Once you buy home workout equipment, you use it for years. That is why the value of not having to replace it is worth many times more than the price difference at the time of purchase.

I have bought various pieces of home workout equipment myself. Among them, the ones I chose by compromising were the ones I ended up replacing later.

I bought screw-on 10kg dumbbells only to find them lacking in weight, leading me to replace them with 20kg dumbbells.
I bought a flat bench because it was cheap, but reached the limit of exercises I could do, forcing me to buy an incline bench.
I bought a 10kg weighted vest, but it wasn't enough, so I had to buy a 20kg model.

These are all things I have experienced myself.

With the 40kg model, you don't need to think about replacing it even if you find the weight insufficient in the future.

Of course, the initial cost is the highest. But if you keep using it for years, the annual cost becomes smaller and smaller.

Even if it feels expensive at first, it is ultimately the most cost-effective in the long run.

In my 8 years of home training, I have realized that it is important to think about “how many years it will last” rather than “how cheap it is now” when it comes to home workout equipment.

Reason 2: Can be adjusted in fine 1kg increments up to 40kg

This is one of the greatest appeals of the Helix Mirror.

For adjustable dumbbells, the precision of weight adjustment greatly affects usability.

For example, with dumbbells that adjust in 5kg increments, there are often situations where you can handle 30kg but 35kg is too heavy.

In that regard, the Helix Mirror adjusts in 1kg increments.

Because you can make fine adjustments to increase the weight by just 1kg, you can build up your strength without overexerting yourself.

You will especially appreciate these 1kg increments for exercises like side raises, arm curls, and shoulder presses.

This fine weight adjustment becomes increasingly valuable not only for beginners but also as you continue your strength training journey.

Reason 3: It will last you until your future, stronger self

“40kg is still too heavy for me.”

I think many people considering a purchase feel this way.

In fact, I felt the same way when I first started strength training.

At first, even 5kg dumbbells felt heavy enough, and 40kg seemed like a different world. I genuinely thought, “There’s no way I’ll ever handle that kind of weight.”

However, as you continue working out at home, your strength gradually increases. A 10kg dumbbell bench press becomes 15kg, then 20kg, and beyond.

Before I knew it, I was challenging myself with weights I couldn't have imagined when I first started.

That is the nature of strength training.

Therefore, choosing the 40kg model doesn't mean you have to use 40kg from the start.

It’s like a partner that lets you start with a weight that suits you for the day and gradually increase it as you grow. Adjustable dumbbells are equipment that will support your progress for a long time.

Choose it not for who you are now, but for your future, stronger self.

Now that I have been training at home for eight years, if I were to buy dumbbells from scratch again, I would choose the 40kg model without hesitation.

Potential downsides of the Helix Mirror 40kg

While I have highly recommended the 40kg model, there are some disadvantages unique to this version.

That would be the width.

When you get close to 40kg, the number of plates inevitably increases. Consequently, the width of the dumbbell also becomes longer.

As a result, it becomes slightly more difficult to perform the “on-the-knee” technique when doing dumbbell bench presses or shoulder presses.

When the dumbbell itself is long, the center of gravity becomes higher, which compromises stability on the knees when using heavy weights.

This is a common feature not just for the Helix Mirror, but for many adjustable dumbbells with this structure.

If you are primarily considering dumbbell presses, this is a point you should understand before purchasing.

That said, if you choose it while understanding this disadvantage, I think it is a dumbbell that offers a high level of satisfaction.

Block-type dumbbells are also recommended if you prioritize dumbbell presses

If you are someone who prioritizes dumbbell presses above all else, block-type dumbbells are also highly recommended👇

I have been using 40kg block-type dumbbells myself for over 4 years.

The biggest appeal of the block type is that the width is short and the contact area is wide, making the 'on-the-knee' position very easy to perform.Because the sides are wide, they sit very stably on the knees.

The heavier the weight, the greater this sense of security really is.

On the other hand, weight adjustments are in increments of about 5kg.

In other words,

Helix Mirror

• Outstanding ease of use with 1kg increments

• Can be difficult to handle at heavy weights due to its long width

• High price

Block type

• Large adjustment increments of about 5kg

• The width is short, making it easy to handle even at high weights

• The price is low

These are the differences.

If you are thinking primarily about dumbbell presses, please also refer to my review article on the block-type ones I have been using for over 4 years↓

Conclusion | I would choose the Lysin Helix Mirror 40kg

Finally, I will summarize my conclusion.

Helix Mirror 20kg

★★☆☆☆

I do not recommend it. For the 20kg range, there are models with better cost performance↓

Furthermore, if you want to increase the weight later, it is realistically close to buying a new one.

Helix Mirror 32kg

★★★★☆

It is by no means bad. I think you will be satisfied enough at first.

However, the longer you continue home training, the more likely you are to find it insufficient.

Helix Mirror 40kg

★★★★★

I would choose this one.

It can be used for a long time from beginner to advanced levels, and it can be adjusted in 1kg increments up to 40kg.

And above all,you won't have to think about buying a replacement.Home training equipment is something you use for many years. That is why the initial choice is truly important.

Looking only at the specs, the difference between 20kg, 32kg, and 40kg seems to be only the "weight".

However, in reality, this is a product that requires you to consider future replacements as well.
Therefore, if I were to choose a Helix Mirror now, I would buy the 40kg model without hesitation.

To avoid regretting your choice in a few years by thinking, "I should have just gone with the 40kg from the start," please try to choose your weight with a long-term perspective.

In conclusion

If I were to build a home workout environment from scratch right now and choose a Helix Mirror, I would buy the 40kg model without hesitation.

The reason is that I want to choose based on my "future self," not my "current self."

When I first started working out at home, I felt that even 20kg was heavy enough. However, as I continued, my strength gradually increased, and there were many times when I thought, "I want to go a bit heavier."

That is why I want many people to know the information I learned from inquiring with Lysin: that you cannot easily increase the weight later.

Home workout equipment becomes a partner you will be with for several years. If you choose based solely on reasons like "it's cheap" or "this is enough for now," you may end up having to replace it later.

I hope this article serves as a helpful reference for you to choose dumbbells without regrets.

Thank you once again for reading until the end!
