Alright, so I’ve been messing around in my garage gym setup again. Had this urge to try some kettlebell stuff, you know, swings, maybe some goblet squats, but didn’t really want to splash out on actual kettlebells just yet. They take up space, and I wasn’t sure if I’d stick with it. I looked over at my trusty adjustable dumbbells, the ones with the screw collars.

Thinking it Through
So there I was, staring at the dumbbell. The handle’s okay for presses and rows, obviously, but try swinging that thing? Nah, awkward grip, feels all wrong. My brain started ticking. How could I make this dumbbell handle more like a kettlebell handle? Needed something wider, something I could grip with two hands properly, maybe something that shifted the center of gravity just a tiny bit, though probably not much.
First thought was just duct tape. Wrap a ton of it around the handle to build it up? Seemed messy and probably wouldn’t hold up. Then I saw some old heavy-duty straps I had, the kind you use for tying stuff down on a roof rack. Strong nylon, sturdy buckle. Lightbulb moment.
Putting it Together
Here’s what I did, pretty straightforward really:
- Grabbed one of my dumbbells. I used a lighter one first, maybe 20 pounds, just to be safe.
- Took one of those heavy-duty lashing straps.
- Fed the strap end under the dumbbell handle.
- Brought it back up and over, feeding it through its own buckle.
- Pulled that sucker really tight. Like, wrenched on it hard. The idea was to create a loop sticking up from the dumbbell handle that I could grab.
- Made sure the buckle was positioned out of the way, not where my hand would grip.
- Double-checked everything. Gave the strap loop a good few yanks in different directions. Seemed solid enough, wasn’t slipping on the metal handle.
Giving it a Go
Okay, moment of truth. Picked it up by the strap handle. Felt… different. Not quite a kettlebell, the weight distribution is still mostly like a dumbbell, centered on that bar. But the grip? Way better for two hands.
Tried some two-handed swings. Careful at first. It worked! The strap held fine. Felt much more natural than trying to swing the dumbbell by its actual handle. Did some halo rotations around my head too. Again, the strap made it possible, even if the balance felt a bit off compared to what I imagine a real kettlebell feels like.
Goblet squats were alright too. Holding the strap loop felt okay, maybe a bit less comfortable than a proper kettlebell horn, but totally doable.

Final Thoughts
So, yeah. It’s a hack. A total garage-gym-style workaround. Is it a perfect kettlebell replacement? Absolutely not. The feel is different, the balance is off, and I wouldn’t trust it with super heavy weight or really dynamic, jerky movements. There’s always that tiny worry the strap could slip or the buckle might give way, although mine felt pretty secure.
But for trying out some basic kettlebell movements? Or if you’re stuck with only dumbbells and want a bit of variety? It actually does the job, surprisingly well for something cobbled together in five minutes. Just use common sense, start light, check the strap tightness constantly, and don’t go crazy. It’s a converter, kinda, but keep your expectations grounded. Good enough for a quick session, though.
