The short version: both are good first kettlebells, and the choice is fixed versus adjustable. Buy the Amazon Basics 20 lbif you want the truest kettlebell feel, the lowest entry price, and mostly swings and single-weight work — a solid cast bell that just works. Buy the Yes4All adjustableif you want to progress the weight over time and save space, since one bell covers several loads. The one caveat that tips a lot of beginners toward the fixed bell: swings want a solid, balanced bell, and the adjustable’s plate-loaded handle feels different in the hand. Here is the full comparison.
The verdict up front
If you want the simplest, best-feeling first bell for the least money, buy the Amazon Basics 20 lb kettlebell. It is a vinyl-coated cast-iron bell with the balanced, one-piece feel that swings, goblet squats, and carries are built around, and it is inexpensive to start. If you already know you will want to add weight soon and your floor space is tight, buy the Yes4All adjustable kettlebell— one bell that swaps plates to cover several loads, so it grows with you and replaces a rack of fixed bells. Both train the same movements; the choice is whether you value feel and price or progression and space more.
What they share: the same beginner movements
Whichever you pick, a single kettlebell covers a remarkable amount of training. Both of these handle the core beginner list: swings for hips and conditioning, goblet squats for legs, presses for shoulders, and carries for grip and core. One bell is genuinely enough to build a full conditioning and strength habit, which is why a kettlebell is such an efficient first purchase for a small home gym. If you want a session to run with either bell, our beginner kettlebell workout lays out a simple, effective routine you can start on day one.
With the movements shared, the decision comes down to how the bell is built and what you want it to do over the next year. That is really a question of format — fixed or adjustable — which we zoom out to in fixed vs. adjustable kettlebell. Everything below applies that choice specifically to these two bells.
Where the Amazon Basics wins: feel and lowest entry
The Amazon Basics kettlebell wins on two things a beginner feels immediately: the feel of the bell and the price to start. Because it is a one-piece cast-iron casting, the weight sits exactly where your hands expect it through a swing, and the smooth vinyl coating both protects your floor and softens the bell against your forearm in the rack position. That balanced, predictable feel is the “true” kettlebell feel, and it is the thing that makes the fundamental movements click for a new lifter.
It is also the cheapest way to start. A single fixed bell is inexpensive, you own it outright, and there is nothing to assemble or adjust — you pick it up and swing. The honest limits are two, and both come from it being fixed at 20 lb. First, 20 lb gets light for heavy swings fairly quickly as your hips get strong, so it is a starting weight rather than a forever weight. Second, because you cannot change it, you will want a second, heavier bell later to keep progressing. Neither is a flaw so much as the nature of a fixed bell: it is the best-feeling, lowest-cost way in, with a known ceiling.
Where the Yes4All wins: progression and space
The Yes4All adjustable kettlebell wins on progression and space. Because you swap plates to change the weight, one bell covers several loads — so a single purchase carries you from a lighter press to a heavier swing without buying a whole set of fixed bells. That makes it genuinely space-efficient: one bell on the floor instead of three or four, which matters in a spare room or a shared garage. And it grows with you: as you get stronger, you add a plate rather than a new bell, so the bell keeps pace with your training for far longer than a fixed 20-pounder can.
The trade-offs are honest and worth knowing before you buy. The handle feel differsfrom a solid cast bell — a plate-loaded design does not have quite the seamless balance of a one-piece casting, and you notice it most on fast, ballistic reps. And plate swaps take a moment: changing the weight is not as instant as grabbing a different fixed bell, so mid-workout weight jumps are a small chore. For a lifter who values progression and a tidy floor over the last few percent of swing feel, those are fair trades — and it is why we call the Yes4All the space-saving pick.
Cost over time: one bell or a growing set
The price comparison changes depending on how far ahead you look. On day one, the fixed Amazon Basics is cheaper, full stop — a single 20 lb bell is inexpensive and there is nothing else to buy. But kettlebell training rewards having more than one weight: you press lighter than you swing, and you swing lighter than you deadlift or carry, so most people eventually want a range. That is where the maths shifts. If you buy fixed and later add a second and third bell, the running total climbs; the adjustable Yes4All bundles that range into one purchase.
So think about your next twelve months, not just checkout day. If you suspect you will stick with kettlebells and want to progress the weight, paying a step up front for the Yes4All can be cheaper than assembling a set of fixed bells one at a time — and it keeps your floor clear while it does. If you are testing the waters and want the smallest possible outlay to find out whether kettlebell training is for you, the single fixed bell is the low-risk way in. Neither is wrong; they are optimised for different time horizons.
The swing question, settled
This is the detail that decides it for a lot of beginners, so it deserves its own section. The kettlebell swing is the movement the tool is most famous for, and it is ballistic— the bell accelerates fast and your hands have to trust where the weight is. A solid, balanced bell is ideal for that, which is where the fixed Amazon Basics has the edge: its one-piece cast body keeps the load steady and predictable through every fast rep. The Yes4All can swing perfectly well, and plenty of people train swings with it, but the plate-loaded handle feels different and the plates need to be snug so nothing shifts.
So if swings are your main event, lean toward the fixed cast bell for the cleaner feel. If swings are just one movement among goblet squats, presses, and carries — and progression matters more to you — the adjustable’s different handle feel is a minor compromise for the weight range you gain. Match the bell to how you will actually train, and the swing question answers itself.
How to decide
Two questions settle it. First, what do you value more, feel and price or progression and space? If you want the truest kettlebell feel and the lowest possible entry, the fixed Amazon Basics is the pick. If you want one bell that covers several weights and keeps your floor clear, the adjustable Yes4All is built for that. Second, how central are heavy swings?If they are the core of your training, the solid cast bell serves them best; if they are one movement among many, the adjustable’s range is the bigger prize.
For most beginners, we lean toward starting with the fixed 20 lb Amazon Basics— the truest feel, the lowest cost, and the movements that teach you the tool — then adding an adjustable or a heavier fixed bell once you know you are sticking with it. If you are confident you will progress quickly and space is at a premium, start adjustable with the Yes4Alland skip the second purchase. Either way, size the weight to your body and your lifts first — our how to choose a kettlebellguide walks that through — and then get moving with a beginner kettlebell workout.
