What the fuck are these actually meant to work? How are these

They're meant to create a shearing force on your spine so stupid people get injured.

they are very effective as HIIT
they hit the whole back-side chain and a lot of front-side chain
one-handed variants also work on stability
swings are not for normies anyway

if you do it right
its a good glut/hamstring/quad workout
hip thrust is the key
arms/shoulders are just along for the ride

both of these

Also if you can do one armed swings and release at the peak and switch arms. If you want to further challenge your coordination you can release with one hand and then tap the handle once with each hand before grabbing it with the opposite hand that you started with. Also they're kinda fun to do. You can do them with dumbells though if you don't have access/want to invest in kettlebells

>How are these beneficial in any way

Does a really fucking decent job at teaching double extension.

You can also do it like a snatch so you don't strain your back.
To be honest, I hate swings for cardio purposes. Hill sprints are way better/less damaging.
The ultimate in KB use is going into your backyard, finding a tree limb, and practicing throwing the KB over the tree limb. Accelerating a weight to maximum velocity without being forced to pause at the top: This is the purest form of power development and will make you into goku.

It works the back, abs, and legs well, atleast if you use a heavy enough one. It takes a lot of hip power to swing a heavy kettlebell into the air, and good core/back support to bring it back down without flying forward.

The problem is that since people do the swings as cardio they start to fuck up the form at the end. This can lead to some really nasty back injuries as they try to slow the KB down.

There's no reason not to do KB swings on grass or a 4'x4'x1' memory foam and just drop the thing on the eccentric.

The solution is not to do it for cardio and not fuck up the form. The eccentric movement is key.
