I've heard that the electrical impulses can fuck up your muscles which gives you uncontrollable muscle spasms

or you could do some planks

your call

>>37023215
yes they work
is that what you wanted to hear?

>>37023287
you speaking from experience?

I mean, there are studies that show just flexing your muscles will lead to more muscle growth than just sitting around doing nothing, and this stimulates them to be flexed...

So yes it works, it's just no where near optimal, and you'd be better off buying like a $10 ab wheel and not being a lazy pile of shit.
