What are Soft Kettlebells?

Soft kettlebells are constructed with a soft outer covering that helps to protect the user from injury during a workout. Most are filled with some type of filler such as sand or water. They’re made in a range of different weights, and models. Each manufacturer offers their version of the soft kettlebell, but the best will feature high quality and durable materials that resist wear and tear under heavy use.

When shopping around, it’s wise to make sure that this kettlebell style is made with strong and durable materials and reinforced stitching. Also, choose a model that features a large handle that is comfortable to hold and offers a good grip to reduce the chance of injury from equipment failure. 

Soft Kettlebell vs Hardstyle Kettlebell

We’ve learned what Soft kettlebells are, but how do they stack up to hardstyle kettlebells? Hardstyle kettlebells are made of cast iron or steel materials, in most cases. They are sometimes made of hard plastic or covered in rubberized material. You’ll notice the difference between the two when you compare them side by side.

Great for Home & Travel!

You can buy hardstyle kettlebells with adjustable weights, but most traditional kettlebells are one solid weight.

Thus making them difficult to carry if you plan on lugging your hardstyle kettlebell to the gym and back. These are only a few of the considerations to be aware of when choosing between the two.

We will look at more later.

There are pros and cons to any type of exercise equipment. When deciding which type is best for you, it’s a good idea to weigh the benefits against the drawbacks.

Lifestyle is also something to think about. Where you live and the type of flooring you have in your home will matters.

Advantages of Softstyle Kettlebells

Softstyle kettlebells have a few advantages over the hardstyle type. The advantages include:

-Safer to use

Hardstyle Kettlebells are more dangerous when you’re swinging them around because they have no padding. If you make an impact on a part of your body, you’re likely to get a nasty bruise or worse. Softstyle is padded and less likely to cause injury. They’re also safer if you have children in the house thanks to the padding. 

-Quiet on floors

The padding on softstyle kettlebells muffles the sound when the bells are placed on the floor. The hardstyle is louder and may disturb people in other rooms of the house.

If you live in an apartment or duplex with neighbors nearby, the sound is less likely to be heard by the people next door. 

-Will not damage floors or carpet

There is always the risk of damaging wood or tile floors with hardstyle kettlebells. The hard materials could cause breakage of tile floors or scratches, grooves or dents if dropped on wood floors. The soft exterior provides several benefits over kettlebells without this protection. 

-Will not rust

Soft kettlebells are made of materials that are resistant to rust and corrosion. Most come with waterproof liners on the inside of the bag. This prevents the fillers from leaking.

Hardstyle Kettlebells made of cast iron may rust when exposed to moisture such as sweat or humidity. 

-More portable and convenient

Softstyle kettlebells may be emptied of their contents for more convenient carrying and storage. 

-Better adjustability

You can fill the soft-style kettlebells with the desired amount of sand or water to achieve a range of weights. This means that just one soft style kettlebell can take the place of a dozen Hardstyle types. It takes up less room in your home and it’s less expensive to have a range of weights at your disposal. 

Advantages of Hardstyle Kettlebells

-Heavier weight options

The better hardstyle kettlebells are made from one solid piece of metal. They provide heavier weight options than Softstyle. After you’ve been working out with kettlebells for a while, you’ll be ready for a heavier weight. In fact, it will be necessary to continue to present a challenge for building endurance and strength. 

-Less bulky

Hardstyle Kettlebells come in a variety of shapes and sizes. In general, most are less bulky than the sand or water-filled versions. 

-More stable

Hardstyle Kettlebells are one solid piece of metal. This means that they are stable. Softstyle bells are filled with materials that have a tendency to move and shift. The weight is not always evenly distributed and this can throw you off when you’re working out, creating an imbalance and potential injuries such as a pulled muscle, tendon or other damage to soft tissue from the strain. 

6 Soft Kettlebell Styles I Have Reviewed

There are a few different types of soft kettlebells available. These include sand-filled and water-filled. We pulled a few examples to show you the differences from one brand to another. 

Sand-filled Soft Kettlebells

JMJ Products version of the sand-filled soft kettlebell has a handle that is like a suitcase, complete with grips and a soft covering. This kettlebell is completely adjustable because the bag can be filled with either wet or dry sand, pebbles, rocks, dirt, chains, buckshot or other materials.

You can fill the bag with the desired weight up to 35 pounds to customize your workout, and the inside of the bag is lined to keep the outside free of dust or leakage from the materials inside.

Meister Elite soft kettlebell

Meister’s Soft Kettlebell is similar in construction with a slightly different shape. Although it doesn’t advertise that you can adjust the weight, you will need to buy the sand for filling, sold separately. It comes empty, so you can add the desired amount of sand. 

Water-filled Soft Kettlebells

When is a Soft Kettlebell Better to Use Than a Hardstyle?

-Use in apartment or home

The soft kettlebell is usually a better choice when you live in an apartment with neighbors or in a home with other people. The reason for this is because of the noise that the hardstyle cause when they come in contact with the floor. If a Hardstyle kettlebell slips out of your hand during an exercise, it is more likely to cause damage to ceilings, windows, walls or floors. 

-Fewer injuries and safer to use around kids

The padding that covers the soft kettlebell adds a safety feature that lessens the damage of an impact. If a child picks up the kettlebell and drops it on their feet, there will be at least some protection thanks to the padding. 

-Much more portable and easier to store

Soft kettlebells may be emptied of the filler which makes them more portable and lighter for carrying to the gym and back. This feature also saves space in storage when the equipment is not in use.

-More functional and versatile

You can use just one soft-style kettlebell to cover a range of weights that would require more cast-iron or steel kettlebells. If you use an adjustable softstyle, then you will be able to adjust the weight by the amount of filler that you use. 

Final Thoughts

The debate over soft-style kettlebells vs hardstyle is ongoing, but it’s not really a matter of one being any better than the other. They’re just very different and it’s really more a matter of which fits better into your lifestyle.

In most aspects, soft kettlebells are safer, quieter, and more convenient than hardstyle. You trade the stability of solid construction and heavier weight of the hardstyle, which is why some prefer to stick with this type, while others are in favor of the versatility of soft kettlebells.
