You have one kettlebell. Good. You don’t need more. You need better programming.
After I finally moved up to a 24 kg bell, I trained with just that one for close to a year before buying another size. Not because I was being minimalist on purpose. I just couldn’t justify spending money on more gear when I hadn’t exhausted what I already had. Turns out, I wasn’t even close.
Most people buy a heavier bell the moment their current one starts feeling manageable. That’s one option. But there are a dozen ways to make the same weight harder before you need to go up.
Why constraints work
When you only have one bell, you can’t just slap more weight on the bar and call it progressive overload. You have to get creative with other variables. Volume, density, tempo, complexity, rest periods. These are all levers you can pull, and most people only ever touch one of them.
A 24 kg press for 3x5 with two minutes rest is a completely different stimulus than 24 kg for 5x5 with 60 seconds rest. Same weight. Same movement. Harder session.
This is actually better training in some ways. You learn to manipulate programming variables instead of just chasing heavier loads. That skill stays with you even when you eventually have a full rack.
Tactics that make one weight feel like five
Complexes
String movements together without putting the bell down. A clean into a press into a squat into a row. That’s one rep. Do five per side. Your 24 suddenly feels like a 32.
A simple one I keep coming back to:
- Clean x 1
- Press x 1
- Front squat x 1
- Snatch x 1
Five rounds per side. Rest 90 seconds between sides. Takes about 15 minutes. You’ll be breathing hard by round three.
Chains
Similar to complexes, but you add a rep each round. Clean x 1, press x 1. Then clean x 2, press x 2. Up to 5 and back down. The volume sneaks up on you fast. By round 4 you’re questioning your life choices.
Tempo work
Slow down the eccentric. A goblet squat with a 3-second lowering phase turns a moderate weight into a brutal one. Try a set of 8 with a 3-second descent and tell me your 20 kg bell is too light.
Same idea works for presses. Strict press up, 3 to 4 seconds on the way down. Five reps per side and your shoulders are cooked.
Single-arm emphasis
Everything single-arm. Single-arm swings, single-arm rows, single-arm farmer carries. You cut your effective load in half compared to two-hand movements, which means your “moderate” bell becomes your heavy bell. Plus you get anti-rotation work through your trunk on basically every rep.
EMOM structures
Every minute on the minute formats let you manipulate density without changing weight or reps. Start with 5 presses EMOM for 10 minutes. Too easy? Do 6 per minute. Still easy? Drop the clock to every 45 seconds. Same weight, same reps, way harder.
High-rep sets
20-rep sets of swings or snatches are a different animal than sets of 10. Your grip and your lungs will give out before your legs do. A 10-minute snatch test at a “moderate” weight will humble anyone.
Two sessions you can steal
Session A: Grind day
- Turkish get-up: 3 per side, slow
- Single-arm press: 5x5 per side, 60 seconds rest
- Goblet squat: 4x8, 3-second eccentric
- Single-arm row: 3x10 per side
About 30 minutes. Nothing flashy. Just solid work.
Session B: Conditioning day
Complex, 5 rounds per side, 90 seconds rest between sides:
- Clean x 2
- Press x 2
- Front squat x 2
Then:
- One-arm swings: 100 reps. 10x10 EMOM, alternating sides every set.
25 minutes total. The complex gasses your upper body, then the swings finish off your posterior chain.
When you actually need a second bell
I’m not going to pretend one bell lasts forever. There’s a ceiling.
If you want to do double kettlebell work (double cleans, double presses, double front squats), you obviously need two matching bells. Doubles are a different training stimulus and worth exploring eventually.
Heavy pressing has a limit too. Once you can strict press your bell for sets of 8 or more, tempo and density tricks can only stretch things so far. At some point, you need a heavier bell.
Same goes for swings. If your one bell is a 24 and you’re ripping through 100 reps without breaking a sweat, a 32 is the right call.
But honestly? Most people hit that point later than they think. I see people buying their third and fourth bell when they haven’t done a single complex with their first one. The weight isn’t the problem. The programming is.
The buy list when you’re ready
When you do buy your second bell, go one size up from what you have. If you’re swinging a 24, get a 28. If you’re pressing a 16, get a 20. Don’t skip sizes. The jumps in kettlebells are big enough already.
That gives you a light bell for high-rep work and pressing, and a heavy bell for swings and squats. Two bells, two sizes, and you’re set for a long time.
One bell got me through my first year. I’ve had three bells for most of the time since then, and that covers basically everything I need. The collection doesn’t need to be big. It needs to be used.
