Programming Your Swings: Heavier, Lighter, and Why It Matters

The following question has come up in my training group a few times recently as we’ve been working with different rep patterns in our kettlebell Swings (that is: how many Swings we do in a row, how many times we repeat that number, and how much rest we take in between).

Is it better to do fewer Swings with a heavier kettlebell? Or more Swings with a lighter one?

The answer is both/and.

Without understanding the benefits of each choice, most people decide based on how fast they want it over with, or how confident they feel with the kettlebell weights they have access to. But the more exposure you have to Swings with different weights, the more accurately you can judge which weight to use – and how long you can use it without losing power.

That’s the real choice that needs challenging.

Not just, “How do I get this done fast?” but:

Can I harden myself to working harder for longer?
Can I learn how my body responds to heavier weights than I’ve been letting myself use?

I remember asking this same question when I was starting out and trying to understand how different choices affected my body. I also understand that a hardstyle kettlebell class can feel overwhelming – the work is often intense, and necessarily so. I create an environment of safety and self-regulation in my groups, but that doesn’t change the fact that a lot of it feels really hard.

That’s part of it. If something works as well as this style of training works, you can feel it working, you know? 😉

This is where treating your training as a practice – and an ongoing experiment – becomes useful. You’re not in the room to impress anyone, or to switch off your brain and blindly follow whoever’s at the front.

You’re here to use your body.

So you have to pay attention to it.

What Heavy Swings Do

When you choose a kettlebell that is heavy – and by heavy I mean one you can do up to ca.10-20 Swings with before you lose power* – it changes things.

*Losing power means your Swings go soggy. Your knees soften. The bell doesn’t reach hip height. There’s no float at the apex. You must stop before this happens. But you also need to pay attention so you can recognise what the last strong Swing before that felt like. That awareness only comes from exposure and experimentation over time.

If you can perform strong, snappy, genuinely heavy Swings, for however many reps you can maintain power (and yes, this will be far fewer than your lighter Swings), you build power.

Power is your body’s ability to handle force and shock resiliently. It’s how quickly your muscles contract to protect you or respond to something happening around you.

It’s the reason your dog can spot a squirrel before you and lunge like a demon, yet you somehow stay upright and the squirrel lives to squirrel another day. Or, more relevantly, it’s why you can keep producing strong Swings.

Building power also builds strength (and I know you’re here for that).

Heavy Swings strengthen everything that requires you to get upright quickly and stay there:

Whether you deadlift or dance in your spare time, it will feel stronger.
Squats and lunges feel more powerful out of the bottom.
Anything that demands you stand your ground improves (see: dog vs squirrel).
And perhaps most importantly, you stop quietly wondering whether something feels hard because you’re “getting older.”

They’ll also create a bum the 90s told us to hide – but that people now risk life and limb on operating tables trying to manufacture. The difference is that our are hard-earned, solid, and actually useful.

If it requires you to get or stay upright quickly, hard heavy Swings will improve it more effectively than basically anything else I know.

What Lighter Swings Are For

After all that, you’d be forgiven for thinking lighter Swings don’t matter.

They absolutely do.

First, “lighter” is relative. Notice I’m not saying light, I’m saying lighter. Lighter in relation to your heavy.

Your lighter and my lighter are probably very different. And even your own lighter weight will change over time depending on how many Swings you’ve done in your life, how many weights you’ve used, and what the current session demands.

For example, these require a lighter kettlebell:

Five minutes of Swings at 40 seconds on / 20 seconds off
100 Swings unbroken
30+ minutes of 15 Swings EMOM

Compared to something like:

10 sets of 5 reps with 2 minutes rest
3 x Power Swing EMOM for 10 minutes
20 Swings, 20 deep breaths, AMRAP in 15 minutes

Protocols that suit lighter kettlebells build power endurance and cardiovascular capacity, protocols that suit heavier kettlebells build strength and power generation.

For both protocols and both ends of the heavy–light spectrum, the real question is the same:

How much can you do, and for how long?

If you can regularly answer that question with “more than last time,” here’s what happens, and the cool thing it – it’s circular.

You get fitter, stronger, and more powerful.

Because of that, your body undergoes real structural and physiological changes: muscles grow denser, connective tissue toughens, your nervous system becomes more efficient, your energy systems improve.

Those changes allow you to handle heavier kettlebells both for endurance-focused work and for power-focused work.

Handling heavier kettlebells then demands more from you. Your body responds by building itself stronger (sleep and food play a BIG part in this, but that’s another post!)

This response pushes the “how much and how long?” question further.

Which makes you fitter, stronger, and more powerful again.

And so it continues.

When Everything Shifts Heavier

Being able to move everything up a bell is a direct reflection of the physiological adaptations happening inside your body.

Muscles grow and increase in density.
Bones and connective tissue become tougher.
Your metabolic system becomes more efficient at using energy.

And it feels wildly satisfying, physically and mentally. This is what kept me coming back, right at the beginning when I started exploring the question myself: is it better to do heavy Swings for a few reps or lighter Swings for more reps?

The Concise Answer To Our Question (Read Carefully)

You need to do heavy Swings for low reps ✅
so that you can do lighter Swings for high reps ✅
so that you can do even heavier Swings for low reps ✅
so that you can do heavier-than-before Swings for even higher reps ✅

The more exposure you have to this cycle, the more options you have, the better condition your body is in.

Moral of the ramble-blog:
Always aim to use the heaviest kettlebell you can — safely — for whatever it is you’re doing.
