Best Adjustable Kettlebell Under $100 (2026)

My rule for this list: each kettlebell had to be $100 or less on Amazon when I checked, and I took the weight settings from the current listing, not from memory. Most pages that rank for this search are general “best adjustable kettlebell” lists where the budget pick is an afterthought, and a few quote prices that are way off. One review lists the Apex at $93.46. It was $47.99 when I checked. Another puts the Stamina Versa-Bell at “$90 to $130”. It was $138.99. So I built a list that sticks to the budget.

How I built it: this guide is research-based. I compared current Amazon listings and published reviews. I haven’t hands-on tested these kettlebells. Prices are what I saw on Amazon on Oct 25, 2026. Prices change daily, so check the current price before you buy.

The picks

1. Yes4All Adjustable Kettlebell: best overall under $100

This one gets you to 40 lb for $89.99, which is the most weight per dollar of any all-in-one pick here (about $2.25 per pound). The listing gives 7 settings: 7.8, 12.4, 17.9, 23.9, 29.9, 35.4, and 40 lb. It’s cast iron, stands 10″ tall, has a flat base so it stays upright, and comes with a 1-year warranty and 30-day returns (Amazon listing). It’s rated 4.6 from 954 ratings. A couple of reviews say it rattles a little and to read the lock instructions carefully. One reviewer weighed theirs at 39.4 lb. Heads-up: some review sites describe it as “10 to 40 lb”, but the current listing starts at 7.8 lb. Check price on Amazon

2. Apex Kettlebell Handle Set: best if you already own plates

At $47.99 it’s the cheapest way to get to 50 lb, but only if you already have standard 1″ plates. The box has a 15 lb cast iron handle, a 5 lb base, 4 plastic spacers, and a locking pin, so it starts at 20 lb. To go heavier, you swap the spacers for your own 2.5, 5, or 10 lb plates, up to 30 lb more (Amazon listing). Plates are sold separately. It has a 2-year warranty and is rated 4.5 from 870 ratings. If 20 lb is too heavy to start with, skip this one. [UNVERIFIED: the title says “15 to 50lb”, but the bullets say it starts at 20 lb. I’d go by the 20 lb.] Check price on Amazon

3. Yagud Adjustable Kettlebell (22.5 lb): best quick-change under $100

Dial-style kettlebells usually cost $149 or more. This is the only quick-change one I found under $100 with a decent number of ratings. The 22.5 lb version is $79.99 and has 7 settings: 3.5, 7, 10, 13, 16, 19.5, and 22.5 lb. The handle is aluminum, the plates are steel, and they sit inside a plastic (ABS) shell. It’s 8.3″ across and 12.6″ tall (Amazon listing). It’s rated 4.7, but that’s from only 55 ratings, and the listing is new (first available May 2026, per a search snippet). The top weight is low, so this suits lighter swings and accessory work more than heavy training. The 44 lb version was $139.99, over my cap. [UNVERIFIED: the lightest setting. One line says 2.5 lb, but the list of settings starts at 3.5 lb.] Check price on Amazon

4. Polyfit Adjustable Kettlebell: best light starter

This one’s for someone just starting out or doing light work. It’s $45.99 and gives you 3 weights: 5, 8, and 12 lb. It has a soft PE coating, comes in colors, and includes a laminated workout guide (Amazon listing). It’s the best-rated pick here: 4.8 from 1,004 ratings. The catch is the 12 lb ceiling. One reviewer wished it went to 20 lb, and you’ll probably outgrow it fast for swings. Check price on Amazon

How to choose

Start with the top weight you’ll need, not the bottom. Most people outgrow light bells fastest on swings and goblet squats. If you want one bell for a long time, the Yes4All (40 lb) or Apex (50 lb with plates) makes more sense than a 12 or 22.5 lb top end.
Check what’s in the box. The Apex is a handle set. Without your own 1″ plates, it’s a 20 lb kettlebell.
Speed vs. feel. Quick-change bells like the Yagud switch faster between sets. Plate-and-lock bells like the Yes4All take longer, but they’re cast iron all the way around.
Count the ratings. 954 and 870 ratings tell you more than 55. Newer listings can be fine, but there’s less history to go on.
Build the corner. A kettlebell pairs well with adjustable dumbbells from my under $200 or under $300 lists and a bench from my weight bench under $150 list.
