Comparison of Strengthbae Classic, Competition, and Adjustable Kettlebells

Comparison of Strengthbae Classic, Competition, and Adjustable Kettlebells

Strengthbae Kettlebells are available in three main options: Classic Kettlebell, Competition Kettlebell, and Adjustable Kettlebell. Each has different characteristics and advantages, allowing you to choose based on your training needs, storage space, and personal preferences.

All three types of kettlebells can be used for various strength, conditioning, and functional training exercises, both for home gyms and commercial gyms. To understand the differences and determine which option is most suitable, let's look at the characteristics of each kettlebell type below.

Understanding the Strengthbae Classic Kettlebell

The Strengthbae Classic Kettlebell is made from solid cast iron in a single-piece mold without welded joints, providing a strong construction that is durable and suitable for intensive use. Its surface features a rust-resistant powder coat finish that also provides a non-slip grip and is suitable for use with chalk.

The Classic Kettlebell has body and handle dimensions that vary according to its weight. Lighter kettlebells have a more compact size, making them easier to control, including for beginners, women, teenagers, and seniors. It is available in a range of 2.5–48.5 kg with color coding on the grip to make the weight easier to identify.

The handle provides an ergonomic gripping area to support various movements such as kettlebell swings, cleans, snatches, presses, and goblet squats.

Understanding the Strengthbae Competition Kettlebell

The Strengthbae Competition Kettlebell is designed with a steel hollow body, meaning the hollow steel body creates weight differences through variations in material thickness. The bottom of the body is also designed with an opening without additional weights inside. This design helps maintain consistent weight distribution and center of mass.

Its main advantage is that the body size remains the same across all weight options. The height, diameter, and 35 mm handle size with a wide opening remain consistent, so the kettlebell's position when placed on the rack or its distance from the floor does not change as you increase the weight.

This allows your body to adapt to increased loads without having to significantly change your technique. The Strengthbae Competition Kettlebell is also comparable to kettlebells used in hybrid races such as the farmer's carry in HYROX.

The Strengthbae Competition Kettlebell is available from 4–48 kg. Options include competition weights from 8–32 kg in 4 kg increments, transition weights from 10–20 kg in 2 kg increments marked with black lines, as well as 4 kg and 6 kg for technique training and 36–48 kg for higher-load training.

Understanding the Strengthbae Adjustable Kettlebell

The Strengthbae Adjustable Kettlebell combines convenient weight adjustment with a competition kettlebell-style shape. One unit has the same body shape, diameter, and handle size across all weight settings.

Its weight can be adjusted from 12–32 kg with flexible weight increments. The weight adjustment uses a tight screw locking mechanism that securely locks the weight plates to prevent them from wobbling or shifting during dynamic movements such as swings, cleans, and snatches.

With one Adjustable Kettlebell, you can replace multiple fixed kettlebells, making it more practical, space-efficient, and economical, especially for home gyms.

Physical Differences Between the Three Kettlebells

The three types of kettlebells have different shapes and systems. These differences affect not only the weight and size of the equipment, but can also influence how you grip, swing, and position the kettlebell on your forearm during training.

  • Strengthbae Classic Kettlebell is made from solid cast iron. The body and handle become larger as the kettlebell weight increases.

  • Strengthbae Competition Kettlebell is made from a steel hollow body. The body and handle dimensions remain the same across all weight options, providing a more consistent kettlebell position during use.

  • Strengthbae Adjustable Kettlebell has a competition-style outer body with an internal screw system for adjusting the weight according to your needs.

These differences in shape can affect comfort during various movements, especially when the kettlebell is in the rack position and resting against the forearm.

Differences in Handle and Feel During Use

The handle shape and body size affect comfort and how the kettlebell feels during use, especially when transitioning the kettlebell from the hand to the forearm.

  • Strengthbae Classic Kettlebell has a relatively wide handle opening, especially in medium to heavy weights, making it comfortable for two-handed movements such as goblet squats and kettlebell swings. However, users need to adapt to the larger body size when using heavier weights.

  • Strengthbae Competition Kettlebell has a fixed 35 mm handle with a wide opening. This design supports single-arm movements such as cleans, snatches, and jerks more consistently. The kettlebell position against the forearm also remains the same across all weight options.

  • Strengthbae Adjustable Kettlebell has an outer body shape similar to the Competition Kettlebell, so the feel and rack position remain consistent even when the weight is adjusted.

Classic vs Competition vs Adjustable for Home Gyms

Choosing a kettlebell for a home gym should be based on the available space, training needs, and how you want to store your equipment.

Strengthbae Classic Kettlebell

Suitable for those who want to build a kettlebell collection with various weight options. It is available from 2.5 kg for warm-ups, beginners, and light training up to heavier loads for strength training. If you have multiple kettlebells, you should prepare a kettlebell storage rack.

Strengthbae Competition Kettlebell

Suitable for users who regularly perform kettlebell training for HYROX hybrid race training or need consistent kettlebell size and positioning across different weights. Its shape remains the same even when the weight changes, making it easier to maintain training technique.

Strengthbae Adjustable Kettlebell

A practical choice for home gyms with limited space. One unit can replace up to 19 kettlebells with different weights, saving space and reducing the need to purchase multiple separate kettlebells.

Classic vs Competition vs Adjustable for Commercial Gyms

Choosing kettlebells for a commercial gym should consider the number of users, training intensity, exercise variety, and available storage space.

Strengthbae Classic Kettlebell

Suitable for gym businesses that want to provide a complete range of weights for different user levels. Its weight range is broad, from 2.5 kg to 48.5 kg, making it suitable for beginners through users who require heavier loads. If many weight options are available, a kettlebell rack should be used to keep the training area organized and easily accessible.

Strengthbae Competition Kettlebell

Suitable for gyms frequently used by hybrid race participants, athletes, or people who practice kettlebell sport. Consistent body and handle dimensions across different weights help users maintain their technique as they increase the load. Its construction is also suitable for intensive and regular gym use.

Strengthbae Adjustable Kettlebell

Suitable for gyms or studios with limited space that still require a variety of weight options. One unit can provide multiple weight settings, reducing the amount of equipment that needs to be stored. However, for gyms with many users training simultaneously, fixed kettlebells are generally more practical because the weight does not need to be adjusted between users.

Choosing a Kettlebell Based on Exercise Type

All three variants can be used for each kettlebell movement, but some types offer certain advantages depending on the movement:

  • Kettlebell Swing can be performed with Classic, Competition, or Adjustable kettlebells. For two-handed swings, the Classic provides a more spacious grip area.

  • Goblet Squat can be performed with all three kettlebell types because the weight is held in front of the chest.

  • Clean & Jerk is more comfortable with the Competition or Adjustable kettlebell because the handle shape and rack position are more consistent.

  • Snatch requires a controlled grip. Competition and Adjustable kettlebells provide consistent handle dimensions and body positioning, making it easier to transition the kettlebell overhead.

  • Overhead Press can be performed with all three variants, depending on your ability and shoulder strength.

  • Farmer's Carry can be performed with any variant. Choose the weight based on your grip strength and the distance to be covered. However, if you want to simulate the Farmer's Carry used in HYROX, using the Strengthbae Competition Kettlebell is highly recommended.

Choosing a Kettlebell Based on User Needs

Match your kettlebell choice to your training needs, ability, and available space.

Beginners and General Training

Choose the Classic Kettlebell. Weight options starting from 2.5 kg make it easier for beginners to learn basic movements with an appropriate load at a more affordable cost.

Training with Consistent Dimensions

Choose the Competition Kettlebell. Its body size remains the same across all weight options, helping maintain consistent positioning and technique as you increase the load.

Home Gym with Limited Space

Choose the Adjustable Kettlebell. One unit provides weight options from 12–32 kg with 1 kg increments, saving space compared with owning multiple fixed kettlebells.

Need Multiple Weight Options

Choose Classic or Competition Kettlebells in fixed-weight versions. These options are suitable for fitness facilities used by many people because each kettlebell has a predetermined weight and can be used immediately without adjusting the load.

Tips for Choosing a Kettlebell for Beginners

Prioritize technique over weight. Choose a weight that allows you to perform the movement with proper posture and technique.

Master the basic movements. Learn the hip hinge in the kettlebell swing and the rack position before trying movements such as the snatch.

Check the Adjustable Kettlebell lock. Make sure the screw lock is properly installed and securely tightened before performing swinging movements.

Consider storage space. For a home gym, match the number of kettlebells you need with the available space before choosing between fixed or adjustable variants.

FAQ

Which is more suitable for beginners, Classic or Competition Kettlebell?

The Classic Kettlebell is generally easier for beginners because it is available starting from 2.5 kg, with a smaller body size at lighter weights. However, the Competition Kettlebell and Adjustable Kettlebell can also be good choices if you want to become familiar with a competition-style shape and size from the beginning.

Is the Adjustable Kettlebell safe for swings and snatches?

Yes, as long as the locking mechanism is properly secured. The Strengthbae Adjustable Kettlebell uses a tight screw locking mechanism that securely locks the weight plates to prevent them from shifting or wobbling during dynamic movements.

Why does the Competition Kettlebell have the same body size across different weights?

Consistent body dimensions keep the kettlebell position on the forearm, handle distance from the floor, and movement pattern the same across different weight options. This means you do not need to make significant technique adjustments when increasing the weight.

How much space is needed to store a kettlebell in a home gym?

For one Adjustable Kettlebell, an area of approximately 30 × 30 cm is required. If you use several Classic or Competition Kettlebells, a kettlebell rack is recommended to keep them organized and safely stored.

Is the Classic Kettlebell suitable for commercial gyms?

Yes. The Strengthbae Classic Kettlebell uses solid cast iron without welded joints and features a rust-resistant powder coat finish, making it suitable for intensive training in commercial gyms and personal training studios.
