Best Kettlebell for Beginners: How to Buy Your First One

By Aiden Islay Updated November 9, 2026 4 min read

Buying your first kettlebell does not take much. One bell, the right size, from a maker that tells you the real specs. Here is how to get there without wasting money. This is general information, not medical advice.

Quick answer: pick the type (cast iron, competition or adjustable), start lighter than you think, check the handle diameter on the maker’s own page, and ask a doctor or physical therapist first if you have an injury or health condition.

Buying your first kettlebell in 4 steps: pick the type, pick the weight, check the handle and finish, and think about what else you own — The four steps of buying your first kettlebell.

Step 1: pick the type

Cast iron. The standard home bell. A heavier bell is a bigger bell, and the handle gets thicker with the weight. Wide range of sizes. More in competition vs cast iron kettlebells.
Competition. One size at every weight, with a fixed handle width. The choice if you want the same feel as you move up, or you might compete. Whether you need one is answered in competition vs cast iron kettlebells.
Adjustable. One bell that changes weight, so it saves space if you want several sizes. We cover the trade-offs in adjustable vs fixed kettlebells.
Soft. A sand-filled bag with a handle, sold as quieter and gentler on floors. We found no independent evidence on how they perform, so see soft kettlebells before you buy.

Step 2: pick the weight

Start lighter than you think. StrongFirst’s own guide suggests starting sets by strength and warns not to go above them, because bells feel heavier than the number on them. Our guide to what weight to start with has the starting sizes for women and for men, the sources and when to ask a professional first. If a listing gives only pounds, our kettlebell weight chart converts kilograms, pounds and pood, with a pounds-first table.

Step 3: check the handle and finish

Handle width varies. A competition bell holds one width (Rogue’s is 33 mm); on cast iron it changes with weight (Rogue lists about 30 to 44 mm). Check the maker’s listed handle diameter, material and weight tolerance. If a listing hides the specs, that tells you something.

Step 4: think about what else you might own

If you also lift dumbbells, or are weighing the two, read kettlebell vs dumbbell. The honest answer there is that we found no research crowning a winner, and the choice comes down to the moves you want. Thinking of owning more than one bell, or a rack? See kettlebell sets and racks, and for floor-friendly options soft kettlebells. For a 2010 opinion on mass-market kettlebells, see this archive piece.

Before you order

Read the maker’s own page for weight, handle diameter and warranty, and note the date you checked.
Look for both kilograms and pounds on the label.
Check how the seller handles returns.
If you have an injury, a heart, blood pressure or joint condition, or you are pregnant, ask a doctor or physical therapist before you start.

Questions people ask

What is the best kettlebell for beginners?

There is no single best one. For most beginners it comes down to the type, a weight that fits you, and a handle you can grip comfortably. Start with the steps above, then see our starter weight guide.

Which type of kettlebell should a beginner choose?

A cast iron bell is the standard home choice and the simplest place to start. Competition bells keep one size at every weight, adjustable bells save space if you want several weights, and soft bells are sold as quieter on floors. Step 1 above compares the four.

What should I check before ordering a kettlebell?

The maker’s own page for weight, handle diameter and warranty, kilograms and pounds on the label, and how the seller handles returns. Note the date you checked, because prices and specs change.

Do I need anything else with my first kettlebell?

Not to start. One bell is enough to begin, and a rack, a set or floor protection only make sense later. See kettlebell sets and racks and kettlebell storage and floor protection.
