Understanding Kettlebell Types

Cast Iron Kettlebells

Traditional kettlebells are cast from a single piece of iron, creating a seamless, balanced weight. They vary in size based on weight, with heavier bells being physically larger.

Pros:

• Most durable construction
• Wide handle accommodates two hands easily
• Available in the widest weight range (5-200+ lbs)
• Most affordable per pound
• Ideal for swings, goblet squats, rows

Cons:

• Size varies with weight (inconsistent feel)
• May require more storage space as the collection grows
• Handle width varies between weights

Best For: General fitness, CrossFit, strength training, beginners, and anyone building a kettlebell collection.

---

Competition Kettlebells

Competition or sport kettlebells maintain the same outer dimensions regardless of weight. A 16kg bell is the same size and has the same handle as a 32kg bell. They use a steel shell with internal ballast.

Pros:

• Consistent form across all weights
• Standard 35mm handle diameter
• Sits comfortably on the forearm during racks and presses
• Preferred for cleans, snatches, and get-ups
• Color-coded by weight for easy identification

Cons:

• Higher price per bell
• The handle may feel thin for two-handed work
• Less ideal for swings (handle width)
• Takes more space than an equivalent cast-iron weight

Best For: Kettlebell sport athletes, those perfecting technique, Olympic-style movements, and serious practitioners.

---

Adjustable Kettlebells

Adjustable kettlebells combine multiple weights into a single unit using plates, dials, or pin systems. They save space and money compared to buying individual bells.

Pros:

• Replaces 4-6+ individual kettlebells
• Significant space savings
• Cost-effective for multiple weights
• Ideal for apartments and small home gyms

Cons:

• Bulkier than traditional kettlebells
• May feel less natural during movements
• Not suitable for dropping
• Slower to change weight than grabbing a new bell
• Mechanical components can wear over time

Best For: Space-limited home gyms, renters, and those who want variety without multiple bells.

Selecting the Right Weight

Beginner Recommendations

Women:

• Start: 8-12 lbs (4-5 kg) for technique
• Progress to: 18-26 lbs (8-12 kg) for swings
• Goal: 26-35 lbs (12-16 kg) for most movements

Men:

• Start: 18-26 lbs (8-12 kg) for technique
• Progress to: 35-44 lbs (16-20 kg) for swings
• Goal: 44-53 lbs (20-24 kg) for most movements

Exercise-Based Recommendations

Swings and Ballistic Work: Choose a weight you can swing for 20+ reps with good form. This is typically heavier than pressing weights.

Presses and Get-Ups: Select a weight you can press 5-8 times per arm. This is typically lighter than swing weight.

Goblet Squats: Use a weight that allows you to perform 10-12 reps while maintaining upright posture.

Building a Set

Minimal Setup (2 bells):

• Light: For presses, get-ups, windmills
• Heavy: For swings, squats, rows

Standard Setup (3-4 bells):

• Light (12-16 kg): Technical work, warm-ups
• Medium (20-24 kg): Main training weight
• Heavy (28-32 kg): Swings, carries

Complete Setup (5+ bells):

• Build in 4 kg increments for progressive overload

Key Features to Consider

Handle Diameter and Width

• 30-33mm diameter: Standard cast iron, comfortable for most
• 35mm diameter: Competition standard, consistent feel
• 38-40mm diameter: Found on heavier cast iron bells, challenges grip

Handle width matters for two-handed swings. Competition bells have narrower handles, better suited for one-handed work.

Finish and Coating

Powder Coated: Best grip, holds chalk well, standard on quality bells

E-Coat: Smoother finish, good rust resistance, may be slippery

Vinyl/Rubber Coating: Protects floors, quieter, but may feel slick

Raw Iron: Traditional feel, requires maintenance to prevent rust

Base Design

Flat, stable bases allow kettlebells to be used for exercises like renegade rows, push-up variations, and floor storage without rolling.

Weight Accuracy

Competition kettlebells should be within ±1 % of the stated weight. Cast iron bells may vary by 2-5%, which matters less for general training.

Frequently Asked Questions

What weight kettlebell should I start with? Most men should start with 16-20 kg (35-44 lbs), and most women with 8-12 kg (18-26 lbs). When in doubt, start lighter and progress quickly rather than risking injury with too much weight.

Do I need both cast iron and competition kettlebells? Most people do fine with just cast iron bells. Competition bells are only necessary if you are training for kettlebell sport or want a consistent feel across weights.

How many kettlebells do I need? Start with two: one for pressing movements and one heavier bell for swings. Add weights as you progress.

Are adjustable kettlebells worth it? If space is limited, yes. They replace multiple bells in one footprint. However, they feel different than single-cast bells and cannot be dropped.

What exercises can I do with kettlebells? Kettlebells excel at swings, snatches, cleans, presses, get-ups, goblet squats, rows, carries, and windmills. They provide full-body training in a compact package.

How do I prevent kettlebell handles from rusting? Store in dry areas, wipe down after sweaty sessions, and apply a light oil (like 3-in-1) periodically. Powder-coated bells resist rust better than raw iron.
