Why our cast iron dumbbells are among the best?

Gaining trust from customers and sports enthusiasts worldwide, our SD01 Cast Iron Dumbbells are favored and approved by the below features:

Made of cast iron or steel

These fixed-weight dumbbell sets come in multiple sizes, shapes, and the material can also vary. At VIC, we are promoting the SD01 dumbbell in two primary materials: Cast Iron and Steel. Each material has its own distinct characteristics and is one factor that needs to be considered when purchasing dumbbells.

Cast iron material

Cast iron is the standard and typical material used in the free-weight casting industry based on some beneficial properties like:

  • good vibration damping
  • good wear resistance
  • good machinability

Steel

The most important advantages of steel content when it comes to casting dumbbells are the flexibility of metallurgy processing and the most significant variability.

It means that steel dumbbells can customize freely in design, allowing for complex shapes and hollow cross-section sections.

Single cast from solid metal

Our cast iron dumbbell for sale is made of one solid piece of metal, without welding. You can tell by looking at the smooth transition surface from the handle to the flat edges and the point where they are in contact with each other.

Our dumbbells are guaranteed a solid, durable handle that can withstand any impact.

Round end caps

How does this round end form help the training experience of the trainer?

When the dumbbell rolls, they actually give trainers an outstanding possibility to vary their routines and challenge themselves.

For instance, when you do push-ups with a pair of round dumbbells, you can completely feel the added squeezes. Although this exercise can be quite advanced, the result is worth it.

It helps to strengthen the core, stabilize triceps, shoulders, encourage muscle development, etc.

Smooth surface finish

The surface finish directly affects the efficiency and durability of sports equipment. Rough surfaces wear faster and have higher friction coefficients than smooth surfaces, leading to unpleasant training experience, potentially causing injury.

Hence, at VIC, various manufacturing steps are then taken to produce products with the smoothest possible surface finish.

Good gripping

Are you looking for dumbbells with good grip? Consider our SD01 Cast Iron Dumbbells for sale!

The balance between proper design, excellent coating technique, and skilled casting of this product allows you to perform the movement without worrying about gripping or slipping, and it will not tear your hands off either, particularly when sweating.

Kilogram and Pound Markings

At our foundry, we are able to provide any sizes of cast dumbbells to meet any workout needs, regardless of physical condition or fitness experience. Whether you’re a beginner, intermediate or advanced trainer, we’ve got the product for you!

Besides, on the SD01 Cast Iron Dumbbell surface, there is a number inscription that refers to the weight, both in kilogram and pound measurements.

Note: One kilogram equals 2.2 pounds.

Custom Logo

We understand that a distinctive logo is the cornerstone of your brand identity.

Therefore, we are pleased to help you reveal your brand’s personality and send your message through our personalized promotional dumbbell sets.

Please give us your logo concept sketches or your suggestions, and we’ll take care of the rest.

Durability

From the selected material: Cast iron – extremely strong and durable when used appropriately and protected from adverse exposure

To the single casting method: Limits welding joints that can lead to cracking if under severe impact

Combine with a premium coating that ensures dual surface endurance. Our cast iron dumbbells are built to last.

Do cast iron dumbbells really work? 

You can easily see a stack of cast iron dumbbells in every fitness center, high-end gym, or home gym. Due to their efficiency and aesthetics, they are now one of the fundamental pieces of sports equipment. So, yes, they work.

Cast iron dumbbells are relatively compact, affordable, versatile, and often used for joint insulation exercises.

Like other free weights, dumbbell training helps burn calories, stimulate muscles, and increase muscular, cardiovascular strength, endurance, etc.

How heavy should cast iron dumbbells to be? 

Dumbbells aren’t one-size-fits-all.

In spite of the tremendous benefits that the dumbbells offer us, let’s consider their weight carefully to optimize training performance and minimize the risk of injury.

Choosing the right weight can be challenging since it depends on various factors such as your fitness condition, your goal, your experience in weightlifting, gender, age, etc.

Here are some approximate standards for both men and women concerning two common dumbbell exercises.

Dumbbell Curl:

Beginner Novice Intermediate Advanced
Men 13lbs (6kg) 28lbs (13kg) 49lbs (22kg) 77lbs (35kg)
Women 7lbs(3kg) 16lbs (7kg) 29lbs (13kg) 46lbs (21kg)

Dumbbell Bench Press:

Beginner Novice Intermediate Advanced
Men 33lbs (15kg) 56lbs (25kg) 87lbs (39kg) 124lbs (56kg)
Women 12lbs (5kg) 25lbs (11kg) 45lbs (20kg) 71lbs (32kg)

How many cast iron dumbbells do you need?

Our muscles are not equally strong; some are stronger than others. When working out, you need a variety of weights to carry each exercise to achieve their fitness goal.

Therefore, we recommend buying the whole set of dumbbells. With a complete range of different sizes, you would be able to select the best weights for different muscle groups.

However, not everyone has enough space and is willing to pay for the entire dumbbell set, so the solution is to get a cast iron adjustable dumbbell set instead. These are a single set of dumbbells that you can easily adjust the weight plates on the two sides to imitate different weights.

At VIC, both cast iron dumbbell sets and cast iron adjustable dumbbell sets are available!
