Why our cast iron adjustable dumbbells are exceptional?

Cast iron adjustable dumbbells are the ideal, most economical, and versatile free-weights for home gym setup.

So what makes our adjustable dumbbells so efficient, and how can they fit your needs?

Solid weight plates

The adjustable dumbbells can ultimately coordinate with your training routine since you can use several weight settings on a single handheld device and adjust the weight as your wish.

These weight plates on the two sides of a dumbbell are what determine the product’s quality and workout effectiveness.

Therefore, to achieve solidness, corrosion resistance, and endurance for lifetime use, our foundry chooses to manufacture adjustable dumbbell plates by two primary metals: cast iron and steel, combining with sufficient coating technology.

Compact, convenient, and easy to use and store 

Nowadays, as the trend of making personal home gym and purchasing adjustable dumbbell sets is skyrocketing, many people have doubts about: “Are adjustable dumbbells worth it?”

The answer is an absolute yes. They definitely worth the money and trainer’s expectation.

Adjustable cast iron dumbbells are also known as “All-for-one dumbbells”. They are compact, adaptable, easy to use, and store weight tools.

Why?

Regardless of round or hex ones, the traditional dumbbell is a short bar with a fixed amount of weight at each end. They are useful, but to elevate your training routine, you will need multiple sets, not just one. Consequently, these weights can take up a great deal of space in your home for storage.

In that case, an adjustable weight set would be an excellent alternate.

Adjustable free weights are incredibly compact and significantly space-saving since they can eliminate the need for additional pieces of equipment in your cramped workout section.

Yet, not inferior to the other dumbbells, the adjustable one still delivers an excellent training experience. Investing in a single pair of dumbbells with various weighted increments can undoubtedly adapt to the entire workout routine. From toning body workouts, strength exercises, or even heavy lifts and curls can be adequately performed without any barriers or inconvenience.

One of the reasons helping to create a strong brand is the development of a logo.

Undoubtedly, a distinctive logo is the cornerstone of your corporate branding, and it serves to differentiate your brand from others.

Therefore, at VIC casting foundry, we offer professional logo custom service for your adjusted dumbbells. With the executive designing team, we can complete any logo design, and we also support bringing your idea to life.

Durability

Our adjustable dumbbell products comprise of cast iron/steel plates and a steel handlebar.

With vast metal casting expertise, one of our greatest fortes is the most satisfactory standard of cast iron and steel metal.

Cast iron and steel components are favored by their incredible strength, high corrosion resistance level, and durability. In addition, with the support of the fitting coating procedure, this product is made to last.

Cheap price

An adjustable dumbbell set allows you to modify the weight using locking mechanisms to mimic different weights for different training purposes. One adjustable dumbbell can replace multiple fixed dumbbells.

Thus, it is a budget-friendly investment for any home gym.

What is an adjustable dumbbell?

Comparison between adjustable dumbbells vs fixed ones, the similarity is that both weights are made up of a short bar and a set volume of weight on both sides.

What’s different is the adjusted dumbbells come with a range of weights in one unit; other weight plates can be added more to the handle or removed to suit your training needs.

Why adjustable dumbbells?

These changeable weights dumbbells are preferred for three main reasons:

1. Cost-effective:

Suppose you consider building your own gym at home but find it pricey to invest in the entire weight rack. A good alternative will be the adjustable weight set.

2. Space-saving

Compared to the full fixed weight set, the adjustable dumbbell is much smaller in size. Hence, pack-up and storage is more straightforward, more convenient, and making them perfect for at-home use.

3. Efficient

The adjustable dumbbell can do as much work as the other free-weights; it can faultlessly coordinate with your workout progress.

How do adjustable dumbbells work?

The SD03 model is the traditional adjustable dumbbell and the most common one.

It consists of a handle with threaded ends and standard weight plates secured to each end of the handles with weight fasteners (spin-lock collars).

Basically, to use these adjustable weight dumbbells, you have to manually put your desired weight on each end of the pole and secure them in place by twisting a metal lock. When the weight is set, all the movement and exercises can be performed similarly to any other free-weight type.
